Constitution of Mexico

Chapter IIndividual Guarantees

Article 1. Every person in the United Mexican States shall enjoy the guarantees granted by this Constitution, which cannot be restricted or suspended except in such cases and under such conditions as are herein provided

Article 2. Slavery is forbidden in the United Mexican States. Slaves who enter national territory from abroad shall, by this act alone, recover their freedom and enjoy the protection afforded by the laws.

Article 3.⁽¹⁾ The education imparted by the Federal State shall be designed to develop harmoniously all the faculties of the human being and shall foster in him at the same time a love of country and a consciousness of international solidarity, in independence and justice.

Freedom of religious beliefs being guaranteed by Article 24, the standard which shall guide such education shall be maintained entirely apart from any religious doctrine and, based on the results of scientific progress, shall strive against ignorance and its effects, servitudes, fanaticism, and prejudices. Moreover:

It shall be democratic, considering democracy not only as a legal structure and a political regimen, but as a system of life founded on a constant economic, social, and cultural betterment of the people;
It shall be national insofar as -- without hostility or exclusiveness -it shall achieve the understanding of our problems, the utilization of our resources, the defense of our political independence, the assurance of our economic independence, and the continuity and growth of our culture; and
It shall contribute to better human relationships, not only with the elements which it contributes toward strengthening and at the same time inculcating, together with respect for the dignity of the person and the integrity of the family, the conviction of the general interest of society, but also by the care which it devotes to the ideals of brotherhood and equality of rights of all men, avoiding privileges of race, creed, class, sex, or persons.

Private persons may engage in education of all kinds and grades. But as regards elementary, secondary, and normal education (and that of any kind or grade designed for laborers and farm workers) they must previously obtain, in every case, the express authorization of the public power. Such authorization may be refused or revoked by decisions against which there can be no judicial proceedings or recourse.
Private institutions devoted to education of the kinds and grades specified in the preceding section must be without exception in conformity with the provisions of sections I and II of the first paragraph of this article and must also be in harmony with official plans and programs.
Religious corporations, ministers of religion, stock companies which exclusively or predominantly engage in educational activities, and associations or companies devoted to propagation of any religious creed shall not in any way participate in institutions giving elementary, secondary and normal education and education for laborers or field workers.
The State may in its discretion withdraw at any time the recognition of official validity of studies conducted in private institutions.
Elementary education shall be compulsory.
All education given by the State shall be free.
The Congress of the Union, with a view to unifying and coordinating education throughout the Republic, shall issue the necessary laws for dividing the social function of education among the Federation, the States and the Municipalities, for fixing the appropriate financial allocations for this public service and for establishing the penalties applicable to officials who do not comply with or enforce the pertinent provisions, as well as the penalties applicable to all those who infringe such provisions.

Article 4. No person can be prevented from engaging in the profession, industrial or commercial pursuit, or occupation of his choice, provided it is lawful. The exercise of this liberty shall only be forbidden by judicial order when the rights of third parties are infringed, or by administrative order, issued in the manner provided by law, when the rights of society are violated. No one may be deprived of the fruits of his labor except by judicial decision.

The law in each state shall determine the professions which may be practiced only with a degree, and set forth the requirements for obtaining it and the authorities empowered to issue it.

Article 5.⁽²⁾ No one can be compelled to render personal services without due remuneration and without his full consent, excepting labor imposed as a penalty by the judiciary, which shall be governed by the provisions of clauses I and II of Article 123.

Only the following public services shall be obligatory, subject to the conditions set forth in the respective laws: military service and jury service as well as the discharge of the office of municipal councilman and offices of direct or indirect popular election. Duties in relation to elections and the census shall be compulsory and unpaid. Professional services of a social character shall be compulsory and paid according to the provisions of law and with the exceptions fixed thereby.

The State cannot permit the execution of any contract, covenant, or agreement having for its object the restriction, loss or irrevocable sacrifice of the liberty of man, whether for work, education, or religious vows. The law, therefore, does not permit the establishment of monastic orders, whatever be their denomination or purpose.

Likewise no person can legally agree to his own proscription or exile, or to the temporary or permanent renunciation of the exercise of a given profession or industrial or commercial pursuit.

A labor contract shall be binding only to render the services agreed on for the time set by law and may never exceed one year to the detriment of the worker, and in no case may it embrace the waiver, loss, or restriction of any civil or political right.

Non-compliance with such contract by the worker shall only render him civilly liable for damages, but in no case shall it imply coercion against his person.

Article 6. The expression of ideas shall not be subject to any judicial or administrative investigation, unless it offends good morals, infringes the rights of others, incites to crime, or disturbs the public order.

Article 7. Freedom of writing and publishing writings on any subject is inviolable. No law or authority may establish censorship, require bonds from authors or printers, or restrict the freedom of printing, which shall be limited only by the respect due to private life, morals, and public peace. Under no circumstances may a printing press be sequestrated as the instrument of the offense.

The organic laws shall contain whatever provisions may be necessary to prevent the imprisonment of the vendors, newsboys, workmen, and other employees of the establishment publishing the work denounced, under pretext of a denunciation of offenses of the press, unless their guilt is previously established.

Article 8. Public officials and employees shall respect the exercise of the right of petition, provided it is made in writing and in a peaceful and respectful manner; but this right may only be exercised in political matters by citizens of the Republic.

Every petition shall be replied to in writing by the official to whom it is addressed, and said official is bound to inform the petitioner of the decision taken within a brief period.

Article 9. The right to assemble or associate peaceably for any lawful purpose cannot be restricted; but only citizens of the Republic may do so to take part in the political affairs of the country. No armed deliberative meeting is authorized.

No meeting or assembly shall be deemed unlawful which has for its object the petitioning of any authority or the presentation of a protest against any act; nor may it be dissolved, unless insults be proffered against said authority or violence is resorted to, or threats are used to intimidate or compel such authority to render a favorable decision.

Article 10. The inhabitants of the United Mexican States are entitled to have arms of any kind in their possession for their protection and legitimate defense, except such as are expressly forbidden by law, or which the nation may reserve for the exclusive use of the army, navy, or national guard; but they may not carry arms within inhabited places without complying with police regulations.

Article 11. Everyone has the right to enter and leave the Republic, to travel through its territory and to change his residence without necessity of a letter of security, passport, safe-conduct or any other similar requirement. The exercise of this right shall be subordinated to the powers of the judiciary, in cases of civil or criminal liability, and to those of the administrative authorities insofar as concerns the limitations imposed by the laws regarding emigration, immigration and public health of the country, or in regard to undesirable aliens resident in the country.

Article 12. No titles of nobility, or hereditary or prerogatives or honors shall be granted in the United Mexican States, nor shall any effect be given to those granted by other countries.

Article 13. No one may be tried by private laws or special tribunals. No person or corporate body shall have privileges or enjoy emoluments other than those given in compensation for public services and which are set by law. Military jurisdiction shall be recognized for the trial of crimes against and violation of military discipline, but the military tribunals shall in no case have jurisdiction over persons who do not belong to the army. Whenever a civilian is implicated in a military crime or violation, the respective civil authority shall deal with the case.

Article 14. No law shall be given retroactive effect to the detriment of any person whatsoever.

No person shall be deprived of life, liberty, property, possessions, or rights without a trial by a duly created court in which the essential formalities of procedure are observed and in accordance with laws issued prior to the act.

In criminal cases no penalty shall be imposed by mere analogy or by a prior evidence. The penalty must be decreed in a law in every respect applicable to the crime in question.

In civil suits the final judgment shall be according to the letter or the juridical interpretation of the law; in the absence of the latter it shall be based on the general principles of law.

Article 15. No treaty shall be authorized for the extradition of political offenders or of offenders of the common order who have been slaves in the country where the offense was committed. Nor shall any agreement or treaty be entered into which restricts or modifies the guarantees and rights which this Constitution grants to the individual and to the citizen.

Article 16. No one shall be molested in his person, family, domicile, papers, or possessions except by virtue of a written order of the competent authority stating the legal grounds and justification for the action taken. No order of arrest or detention shall be issued against any person other than by the competent judicial authority, and unless same is preceded by a charge, accusation, or complaint for a credible party or by other evidence indicating the probable guilt of the accused; in cases of flagrante delicto, any person may arrest the offender and his accomplices, turning them over without delay to the nearest authorities. Only in urgent cases instituted by the public attorney without previous complaint or indictment and when there is no judicial authority available, may the administrative authorities, on their strictest accountability, order the detention of an accused person, turning him over immediately to the judicial authorities. Every search warrant, which can be issued only by judicial authority and which must be in writing, shall specify the place to be searched, the person or persons to be arrested, and the objects sought, the proceedings to be limited thereto; at the conclusion of which a detailed statement shall be drawn up in the presence of two witnesses proposed by the occupant of the place searched, or by the official making the search in his absence or should he refuse to do so.

Administrative officials may enter private homes for the sole purpose of ascertaining whether the sanitary and police regulations have been complied with; and may demand to be shown the books and documents required to prove compliance with fiscal rulings, in which latter cases they must abide by the provisions of the respective laws and be subject to the formalities prescribed for cases of search.

Article 17. No one may be imprisoned for debts of a purely civil nature. No one may take the law into his own hands, or resort to violence in the enforcement of his rights. The courts shall be open for the administration of justice at such times and under such conditions as the law may establish; their services shall be gratuitous and all judicial costs are, accordingly, prohibited.

Article 18.⁽³⁾ Arrest is permissible only for offenses punishable by imprisonment. The place of detention shall be completely separate from the place used for the serving of sentences.

The federal and state governments shall organize the penal system withintheir respective jurisdictions on the basis of labor, training, and education as a means of social readjustment of the offender. Women shall serve their sentences in places separate from those intended for men for the same purpose.

Governors of States, subject to the provisions of the respective local laws, may conclude agreements of a general nature with the federal government, under which offenders convicted for common offenses may serve their sentence in establishments maintained by the federal executive.

The federal government and the state governments shall establish special institutions for the treatment of juvenile delinquents.

Article 19. No detention shall exceed three days without a formal order of commitment, which shall state the offense with which the accused is charged; the substance thereof; the place, time and circumstances of its commission; and the facts brought to light in the preliminary examination. These facts must be sufficient to establish the corpus delicti and the probable guilt of the accused. All authorities who order a detention or consent thereto, as well as all agents, subordinates, wardens, or jailers who execute it, shall be liable for any breach of this provision.

The trial shall take place only for the offense or offenses set forth in the formal order of commitment. Should it develop, during the course of the proceedings, that another offense, different from that charged, has been committed, a separate accusation must be brought. This, however, shall not prevent the joinder of both proceedings, if deemed advisable.

Any ill-treatment during arrest or confinement; any molesting without legal justification; any exaction or contribution levied in prison are abuses which shall be punishable by law and repressed by the authorities.

Article 20. In every criminal trial the accused shall enjoy the following guarantees:

He shall be freed on demand and on furnishing bail which shall be fixed by the judge, according to his status and the gravity of the offense with which he is charged, provided, however, that such offense is not punishable with more than five years' imprisonment. No requisites shall be necessary other than placing the stipulated sum at the disposal of the proper authorities or giving adequate security or personal bond for acceptance of which the judge is responsible.

The security or bond shall be not more than 250, 000 pesos except for offenses by which the offender profits or the victim suffers financially; for such offenses the security shall be at least three times the amount of the profit obtained or the damage suffered.⁽⁴⁾

He may not be forced to be a witness against himself; wherefore denial of access or other means tending to this end is strictly prohibited.
He shall be publicly notified within forty-eight hours after being turned over to the judicial authorities of the name of his accuser and the nature of and cause for the accusation, so that he may be familiar with the offense with which he is charged, and reply thereto and make a preliminary statement.
He shall be confronted with the witnesses against him, who shall testify in his presence if they are to be found in the place where the trial is held, so that he may cross-examine them in his defense.
All witnesses and other evidence which he may offer shall be heard in his defense, for which he shall be given the time which the law deems necessary for the purpose; he shall furthermore be assisted in securing the presence of the persons whose testimony he may request, provided they are to be found at the place where the trial is held.
He shall be entitled to a public trial by a judge or jury of citizens who can read and write and are also residents of the place and district where the offense was committed, provided the penalty for such offense exceeds one year's imprisonment. The accused shall always be entitled to a trial by jury for all offenses committed by means of the press against the public peace or against the domestic or foreign safety of the nation.
He shall be furnished with all information on record which he may request for his defense.
He shall be tried within four months, if charged with an offense whose maximum penalty does not exceed two years' imprisonment; and within one year, if the maximum penalty is greater.
He shall be heard in his own defense, either personally or by counsel, or by both, as he may desire. Should he have no one to defend him, a list of official counsel shall be submitted to him, in order that he may choose one or more to act in his defense. If the accused does not wish to name any counsel for his defense, after being called upon to do so at the time of his preliminary examination, the court shall appoint his counsel for the defense. The accused may name his counsel immediately upon arrest, and shall be entitled to have him present at every stage of the trial; but he shall be obliged to make him appear as often as required by the court.
In no event may imprisonment or detention be extended through failure to pay counsel fees or for any other monetary obligation, on account of civil liability, or for other similar cause.

Nor shall detention be extended beyond the time set by law as the maximum for the offense charged.

The period of detention shall be reckoned as a part of the term of imprisonment imposed by sentence.

Article 21. The imposition of all penalties is an exclusive attribute of the judiciary. The prosecution of offenses pertains to the public prosecutor and to the judicial police, who shall be under the immediate command and authority of the public prosecutor. The punishment of violations of governmental and police regulations pertains to the administrative authorities, which punishment shall consist solely of imprisonment for a period not exceeding thirty-six hours or of a fine. Should the offender fail to pay the fine, it shall be substituted by a corresponding period of detention, which in no case may exceed fifteen days.

If the offender is a day laborer or a workman, his punishment cannot consist of a fine exceeding the amount of his wages, for one week.

Article 22. Punishment by mutilation and infamy, branding, flogging, beating with sticks, torture of any kind, excessive fines, confiscation of property and any other unusual or extreme penalties are prohibited.

Attachment proceedings covering the whole or part of the property of a person made under judicial authority to cover payment of civil liability arising out of the commission of an offense or for the payment of taxes or fines shall not be deemed a confiscation of property.

Capital punishment for political offenses is likewise prohibited; as regards other offenses, it can only be imposed for high treason committed during a foreign war, parricide, murder that is treacherous, premeditated, or committed for profit, arson, abduction, highway robbery, piracy, and grave military offenses.

Article 23. No criminal trial shall have more than three instances. No person, whether acquitted or convicted, can be tried twice for the same offense. The practice of absolving from the instance⁽⁵⁾ is prohibited.

Article 24. Everyone is free to embrace the religion of his choice and to practice all ceremonies, devotions, or observances of his respective faith, either in places of public worship or at home, provided they do not constitute an offense punishable by law.

Every religious act of public worship must be performed strictly inside places of public worship, which shall at all times be under governmental supervision.

Article 25. Sealed correspondence sent through the mail shall be exempt from search and its violation shall be punishable by law.

Article 26. No member of the army shall in time of peace be quartered in private dwellings without the consent of the owner, nor may he impose any obligation whatsoever. In time of war the military may demand lodging, equipment, provisions, and other assistance, in the manner laid down in the respective martial law.

Article 27. Ownership of the lands and waters within the boundaries of the national territory is vested originally in the Nation, which has had, and has, the right to transmit title thereof to private persons, thereby constituting private property.

Private property shall not be expropriated except for reasons of public use and subject to payment of indemnity.

The Nation shall at all times have the right to impose on private property such limitations as the public interest may demand, as well as the right to regulate the utilization of natural resources which are susceptible of appropriation, in order to conserve them and to ensure a more equitable distribution of public wealth. With this end in view, necessary measures shall be taken to divide up large landed estates; to develop small landed holdings in operation; to create new agricultural centers, with necessary lands and waters; to encourage agriculture in general and to prevent the destruction of natural resources, and to protect property from damage to the detriment of society. Centers of population which at present either have no lands or water or which do not possess them in sufficient quantities for the needs of their inhabitants, shall be entitled to grants thereof, which shall be taken from adjacent properties, the rights of small landed holdings in operation being respected at all times.

In the Nation is vested the direct ownership of all natural resources of the continental shelf and the submarine shelf of the islands; of all minerals or substances, which in veins, ledges, masses or ore pockets, form deposits of a nature distinct from the components of the earth itself, such as the minerals from which industrial metals and metalloids are extracted; deposits of precious stones, rock-salt and the deposits of salt formed by sea water; products derived from the decomposition of rocks, when subterranean works are required for their extraction; mineral or organic deposits of materials susceptible of utilization as fertilizers; solid mineral fuels; petroleum and all solid, liquid, and gaseous hydrocarbons; and the space above the national territory to the extent and within the terms fixed by international law.⁽⁶⁾

In the Nation is likewise vested the ownership of the waters of the territorial seas, within the limits and terms fixed by international law; inland marine waters; those of lagoons and estuaries permanently or intermittently connected with the sea; those of natural, inland lakes which are directly connected with streams having a constant flow; those of rivers and their direct or indirect tributaries from the point in their source where the first permanent, intermittent, or torrential waters begin, to their mouth in the sea, or a lake, lagoon, or estuary forming a part of the public domain; those of constant or intermittent streams and their direct or indirect tributaries, whenever the bed of the stream, throughout the whole or a part of its length, serves as a boundary of the national territory or of two federal divisions, or if it flows from one federal division to another or crosses the boundary line of the Republic; those of lakes, lagoons, or estuaries whose basins, zones, or shores are crossed by the boundary lines of two or more divisions or by the boundary line of the Republic and a neighboring country or when the shoreline serves as the boundary between two federal divisions or of the Republic and a neighboring country; those of springs that issue from beaches, maritime areas, the beds, basins, or shores of lakes, lagoons, or estuaries in the national domain; and waters extracted from mines and the channels, beds, or shores of interior lakes and streams in an area fixed by law. Underground waters may be brought to the surface by artificial works and utilized by the surface owner, but if the public interest so requires or use by others is affected, the Federal Executive may regulate its extraction and utilization, and even establish prohibited areas, the same as may be done with other waters in the public domain. Any other waters not included in the foregoing enumeration shall be considered an integral part of the property through which they flow or in which they are deposited, but if they are located in two or more properties, their utilization shall bedeemed a matter of public use, and shall be subject to laws enacted by the States.⁽⁷⁾

In those cases to which the two preceding paragraphs refer, ownership by the Nation is inalienable and imprescriptible, and the exploitation, use, or appropriation of the resources concerned, by private persons or by companies organized according to Mexican laws, may not be undertaken except through concessions granted by the Federal Executive, in accordance with rules and conditions established by law. The legal rules relating to the working or exploitation of the minerals and substances referred to in the fourth paragraph shall govern the execution and proofs of what is carried out or should be carried out after they go into effect, independent of the date of granting the concessions, and their nonobservance will be grounds for cancellation thereof. The Federal Government has the power to establish national reserves and to abolish them. The declarations pertaining thereto shall be made by the Executive in those cases and conditions prescribed by law. In the case of petroleum, and solid, liquid, or gaseous hydrocarbons no concessions or contracts will be granted nor may those that have been granted continue, and the Nation shall carry out the exploitation of these products, in accordance with the provisions indicated in the respective regulatory law.⁽⁸⁾

It is exclusively a function of the general Nation to conduct, transform, distribute, and supply electric power which is to be used for public service. No concessions for this purpose will be granted to private persons and the Nation will make use of the property and natural resources which are required for these ends.⁽⁹⁾ (Note: A transitory provision of the amendment adding the foregoing paragraph to Article 27 states:

"A regulatory law shall establish the rules to which concessions granted prior to the enactment of the present law (amendment) shall be subject".)

Legal capacity to acquire ownership of lands and waters of the Nation shall be governed by the following provisions:

Only Mexicans by birth or naturalization and Mexican companies have the right to acquire ownership of lands, waters, and their appurtenances, or to obtain concessions for the exploitation of mines or of waters. The State may grant the same right to foreigners, provided they agree before the Ministry of Foreign Relations to consider themselves as nationals in respect to such property, and bind themselves not to invoke the protection of their governments in matters relating thereto; under penalty, in case of noncompliance with this agreement, of forfeiture of the property acquired to the Nation. Under no circumstances may foreigners acquire direct ownership of lands or waters within a zone of one hundred kilometers along the frontiers and of fifty kilometers along the shores of the country.

The State, in accordance with its internal public interests and with principles of reciprocity, may in the discretion of the Secretariat of Foreign Affairs authorize foreign states to acquire, at the permanent sites of the Federal Powers, private ownership of real property necessary for the direct services of their embassies or legations.⁽¹⁰⁾

Religious institutions known as churches, regardless of creed, may in no case acquire, hold, or administer real property or hold mortgages thereon; such property held at present either directly or through an intermediary shall revert to the Nation, any person whosoever being authorized to denounce any property so held. Presumptive evidence shall be sufficient to declare the denunciation well founded. Places of public worship are the property of the Nation, as represented by the Federal Government, which shall determine which of them may continue to be devoted to their present purposes. Bishoprics, rectories, seminaries, asylums, and schools belonging to religious orders, convents, or any other buildings built or intended for the administration, propagation, or teaching of a religious creed shall at once become the property of the Nation by inherent right, to be used exclusively for the public services of the Federal or State Governments, within their respective jurisdictions. All places of public worship hereafter erected shall be the property of the Nation.
Public or private charitable institutions for the rendering of assistance to the needy, for scientific research, the diffusion of knowledge, mutual aid to members, or for any other lawful purpose, may not acquire more real property than actually needed for their purpose and immediately and directly devoted thereto; but they may acquire, hold, or administer mortgages on real property provided the term thereof does not exceed ten years. Under no circumstances may institutions of this kind be under the patronage, direction, administration, charge, or supervision of religious orders or institutions, or of ministers of any religious sect or of their followers, even though the former or the latter may not be in active service.
Commercial stock companies may not acquire, hold, or administer rural properties. Companies of this kind that are organized to operate any manufacturing, mining, or petroleum industry or for any other purpose that is not agricultural, may acquire, hold, or administer lands only of an area that is strictly necessary for their buildings or services, and this area shall be fixed in each particular case by the Federal or State Executive.
Banks duly authorized to operate in accordance with the laws on credit institutions may hold mortgages on urban and rural property in conformity with the provisions of such laws but they may not own or administer more real property than is actually necessary for their direct purpose.
With the exception of the corporate entities referred to in clauses III, IV, and V hereof, and the centers of population which by law or in fact possess a communal status or centers that have received grants or restitutions or have been organized as centers of agricultural population, no other civil corporate entity may hold or administer real property or hold mortgages thereon, with the sole exception of the buildings intended immediately and directly for the purposes of the institution. The States, the Federal District, and the Territories, and all Municipalities in the Republic, shall have full legal capacity to acquire and hold all the real property needed to render public services.

The federal and state laws, within their respective jurisdictions, shall determine in what cases the occupation of private property shall be considered to be of public utility; and in accordance with such laws, the administrative authorities shall issue the respective declaration. The amount fixed as compensation for the expropriated property shall be based on the value recorded in assessment or tax offices for tax purposes, whether this value had been declared by the owner or tacitly accepted by him by having paid taxes on that basis. The increased or decreased value of such private property due to improvements or depreciation which occurred after such assessment is the only portion of the value that shall be subject to the decision of experts and judicial proceedings. This same procedure shall be followed in the case of property whose value is not recorded in the tax offices.

The exercise of actions pertaining to the Nation by virtue of the provisions of this article shall be made effective by judicial procedure, but during these proceedings and by order of the proper courts, which must render a decision within a maximum of one month, the administrative authorities shall proceed without delay to occupy, administer, auction, or sell the lands and waters in question and all their appurtenances, and in no case may the acts of such authorities be set aside until a final decision has been rendered.

⁽¹¹⁾The centers of population which, by law or in fact, possess a communal status shall have legal capacity to enjoy common possession of the lands, forests, and waters belonging to them or which have been or may be restored to them.

All questions, regardless of their origin, concerning the boundaries of communal lands, which are now pending or that may arise hereafter between two or more centers of population, are matters of federal jurisdiction. The Federal Executive shall take cognizance of such controversies and propose a solution to the interested parties. If the latter agree thereto, the proposal of the Executive shall take full effect as a final decision and shall be irrevocable; should they not be in conformity, the party or parties may appeal to the Supreme Court of Justice of the Nation, without prejudice to immediate enforcement of the presidential proposal.

The law shall specify the brief procedure to which the settling of such controversies shall conform.

The following are declared null and void:

All transfers of the lands, waters, and forests of villages, rancherías, groups, or communities made by local officials (jefes políticos), state governors, or other local authorities in violation of the provisions of the Law of June 25, 1856, and other related laws and rulings.
All concessions, deals or sales of lands, waters, and forests made by the Secretariat of Development, the Secretariat of Finance, or any other federal authority from December 1, 1876 to date, which encroach upon or illegally occupy communal lands (ejidos), lands allotted in common, or lands of any other kind belonging to villages, rancherias, groups or communities, and centers of population.
All survey or demarcation-of-boundary proceedings, transfers, alienations, or auction sales effected during the period of time referred to in the preceding sub-clause, by companies, judges, or other federal or state authorities entailing encroachments on or illegal occupation of the lands, waters, or forests of communal holdings (ejidos), lands held in common, or other holdings belonging to centers of population.

The sole exception to the aforesaid nullification shall be the lands to which title has been granted in allotments made in conformity with the Law of June 25, 1856, held by persons in their own name for more than ten years and having an area of not more than fifty hectares.

Divisions or allotments of land among the inhabitants of a given center of population which, although apparently legitimate are not so, due to a mistake or defect, may be annulled at the request of three fourths of the residents holding one fourth so divided, or one fourth of such residents holding three fourths of the lands.
Centers of population which lack communal lands (ejidos) or which are unable to have them restored to them due to lack of titles, impossibility of identification, or because they had been legally transferred, shall be granted sufficient lands and waters to constitute them, in accordance with the needs of the population; but in no case shall they fail to be granted the area needed, and for this purpose the land needed shall be expropriated, at the expense of the Federal Government, to be taken from lands adjoining the villages in question.

The area or individual unit of the grant shall hereafter be not less than ten hectares of moist or irrigated land, or in default of such land its equivalent in other types of land in accordance with the third paragraph of section XV of this article.⁽¹²⁾

For the purpose of carrying out the provisions of this article and of regulating laws that may be enacted, the following are established:

A direct agency of the Federal Executive entrusted with the application and enforcement of the agrarian laws;
An advisory board composed of five persons to be appointed by the President of the Republic and who shall perform the functions specified in the organic laws;
A mixed commission composed of an equal number of representatives of the Federal Government, the local governments, and a representative of the peasants, to be appointed in the manner set forth in the respective regulating law, to function in each State, Territory, and the Federal District, with the powers and duties set forth in the organic and regulatory laws;
Private executive committees for each of the centers of population that are concerned with agrarian cases;
A communal office (comisariado ejidal) for each of the centers of population that possess communal lands (ejidos).

Petitions for a restitution or grant of lands or waters shall be submitted directly to the state and territorial governors.

The governors shall refer the petitions to the mixed commissions, which shall study the cases during a fixed period of time and render a report; the State governors shall approve or modify the report of the mixed commission and issue orders that immediate possession be given to areas which they deem proper. The case shall then be turned over to the Federal Executive for decision.

Whenever the governors fail to comply with the provisions of the preceding paragraph, within the peremptory period of time fixed by law, the report of the mixed commission shall be deemed rejected and the case shall be referred immediately to the Federal Executive.

Inversely, whenever a mixed commission fails to render a report during the peremptory time limit, the Governor shall be empowered to grant possession of the area of land he deems appropriate.

The agency of the Executive and the Agrarian Advisory Board shall report on the approval, rectification, or modification of the reports submitted by the mixed commissions, containing the changes made therein by the local governments, and so notify the President of the Republic, who as the supreme agrarian authority will render a decision.
Landowners affected by decisions granting or restoring communal lands and waters to villages, or who may be affected by future decisions, shall have no ordinary legal right or recourse and cannot institute amparo proceedings.

Persons affected by such decisions shall have solely the right to apply to the Federal Government for payment of the corresponding indemnity. This right must be exercised by the interested parties within one year counting from the date of publication of the respective resolution in the Diario Oficial. After this period has elapsed, no claim is admissible.

Owners or occupants of agricultural or stockraising properties in operation who have been issued or to whom there may be issued in the future certificates of non-affectability may institute amparo proceedings against any illegal deprivation or agrarian claims on their lands or water.⁽¹³⁾

The mixed commissions, the local governments and any other authorities charged with agrarian proceedings cannot in any case affect small agricultural or livestock properties in operation and they shall incur liability for violations of the Constitution if they make grants which affect them.

Small agricultural property is that which does not exceed one hundred hectares of first-class moist or irrigated land or its equivalent in other classes of land, under cultivation.

To determine this equivalence one hectare of irrigated land shall be computed as two hectares of seasonal land; as four of good quality pasturage (agostadero) and as eight as monte (scrub land) or arid pasturage.

Associations of workers, formed to protect their own interests, do not constitute monopolies.

Nor do cooperative associations or societies of producers constitute monopolies, which in defense of their interests or of the general interest, sell directly in foreign markets the domestic or industrial products which are the main source of wealth in the region in which they are produced, and which are articles of prime necessity, provided that such associations are under the supervision and protection of the Federal or State Governments and that they were previously duly authorized for the purpose by the respective legislatures, which latter of themselves or on proposal of the Executive may, when the public need so requires, repeal the authorizations granted for the formation of the associations in question.

Article 29. In the event of invasion, serious disturbance of the public peace, or any other event which may place society in great danger or conflict, only the President of the Mexican Republic, with the consent of the Council of Ministers and with the approval of the Federal Congress, and during adjournments of the latter, of the Permanent Committee, may suspend throughout the country or in a determined place the guarantees which present an obstacle to a rapid and ready combatting of the situation; but he must do so for a limited time, by means of general preventive measures without such suspensions being limited to a specified individual. If the suspension should occur while the Congress is in session, the latter shall grant such authorizations that it deems necessary to enable the Executive to meet the situation.

Article 107.⁽⁴³⁾ All controversies mentioned in Article 103 shall be subject to the legal forms and procedure prescribed by law, on the following bases:

A trial in amparo shall always be held at the instance of the injured party.
The judgment shall always be such that it affects only private individuals, being limited to affording them redress and protection in the special case to which the complaint refers, without making any general declaration as to the law or act on which the complaint is based.

A defect in the complaint may be corrected, whenever the act complained of is based on laws declared unconstitutional by previous decisions of the Supreme Court of Justice.

A defect in the complaint may also be corrected in criminal matters and in behalf of workers in labor disputes, when it is found that there has been a manifest violation of the law against the injured party who is left without defense, and in criminal matters, likewise, when the trial has been based on a law not precisely applicable to the case.

In trials in amparo which contest acts that resulted or could result in depriving ejidos or population groups, or members of an ejido or communal holders having a de facto or de jure communal status, from ownership or possession and enjoyment of their lands, waters, pastures, and woodlands, defects in the complaint must be corrected as provided in regulations; and there shall be no abandonment, discontinuance due to inactivity, or lapse of the legal action, if the rights of ejidos or communal population groups are affected.⁽⁴⁴⁾

In judicial civil, criminal, or labor matters a writ of amparo shall be granted only:

Against final judgments or awards against which no ordinary recourse is available by virtue of which these judgments can be modified or amended, whether the violation of the law is committed in the judgments or awards, or whether, if committed during the course of the trial, the violation prejudices the petitioner's defense to the extent of affecting the judgment; provided that in civil or criminal judicial matters opportune objection and protest were made against it because of refusal to rectify the wrong and that if (the violation) was committed in first instance, it was urged in second instance as a grievance.
Against acts at the trial, the execution of which would be irreparable out of court, or at the conclusion of the trial once all available recourses have been exhausted.
Against acts that affect persons who are strangers to the trial.

In administrative matters, amparo may be invoked against decisions which cause an injury that cannot be remedied through any legal recourse, trial, or defense. It shall not be necessary to exhaust these remedies when the law that established them, in authorizing the suspension of the contested act, demand greater requirements than the regulatory law for trials in amparo requires as a condition for ordering such suspension.
Except as provided in the following section, a writ of amparo against final decisions or awards, for violations committed therein shall be applied for directly to the Supreme Court of Justice, which shall render its decision without other evidence than the original complaint, a certified copy of the claims of the aggrieved party, which shall be added to those made by the third party affected, the latter's complaint submitted either by the Attorney General of the Republic or his designated agent, and that of the responsible authority.
A writ of amparo against final decision or awards shall be applied for directly to the Full Circuit Court (Tribunal Colegiado de Circuito) within whose jurisdiction is the domicile of the authority who pronounced the decision or award, whenever the complaint is based on substantial violations committed during the course of the trial or on civil or criminal judgments against which there is no recourse of appeal, regardless of what such alleged violations may be.

Whenever a writ of amparo is sought against final civil or criminal judgments or awards relating to labor matters, based on alleged substantial violations committed during the course of the trial or violations contained in the judgment or award, it must be invoked jointly for all such allegations, submitting the writ to the appropriate full circuit court, which shall render a decision solely with respect to the substantial violations during the trial, and if the judgment is unfavorable to the aggrieved party, shall remit the case to the Supreme Court of Justice to decide on the violations committed in the judgment or award.

As to the application and procedure in amparo cases before the full circuit court, the provisions of the preceding section shall be observed. When this procedure has been completed, a judgment shall be rendered according to the procedure prescribed by law.

When a writ of amparo is sought against acts at the trial, outside the trial or after its conclusion, or if persons foreign to the case are affected, against laws or against acts of administrative authorities, application shall be made to the district judge in whose jurisdiction is located the place in which the act in question was performed or was to be performed, and the procedure shall be limited to the report from the authority in question, to a hearing to which a single summons will include the order for submission of the report and for evidence to be presented by the interested parties and their allegations, the judgment to be rendered at this same hearing.
Judgments in amparo rendered by district judges are subject to review. The Supreme Court of Justice will review such judgments in the following cases:

When a law is impugned as unconstitutional or if any of the cases included in sections II and III of Article 103 are concerned.
Whenever the responsible authority against whom amparo is granted is a federal administrative authority.
Whenever, in criminal cases, merely the violation of Article 22 of this Constitution is alleged.

In all other cases the review will be made by a full circuit court and their decisions may not be appealed.

Decisions in direct amparo rendered by a full circuit court may not be appealed unless the decision involves the unconstitutionality of a law or establishes a direct interpretation of a provision of the Constitution, in which case it may be appealed to the Supreme Court of Justice, limited exclusively to the decision of actual constitutional questions.

A decision of a full circuit court may not be appealed if it is based on a precedent established by the Supreme Court of Justice as to the constitutionality of a law or the direct interpretation of a provision of the Constitution.

Contested acts may be subject to suspension in those cases and under conditions and guarantees specified by law, with respect to which account shall be taken of the nature of the alleged violation, the difficulty of remedying the damages that might be incurred by the aggrieved party by its performance, and damages that the suspension might cause to third parties and the public interest.

A suspension must be granted with respect to final judgments in criminal matters at the time notice is given of the application for a writ of amparo, and in civil matters when bond is posted by the complainant to cover liability for damages occasioned by the suspension, but this is waived if the other party gives bond (contrafianza) to ensure restoration of things as they were if amparo is granted and to pay resulting damages.

The suspension shall be requested from the responsible authority, in the case of direct amparo before the Supreme Court of Justice or the full circuit court, in which case the aggrieved party shall notify the responsible authority, within the period fixed by law and under affirmation to tell the truth, of the claim for amparo, accompanied by two copies, one for use in the case and the other to be transmitted to the opposing party. In other cases, decisions as to suspension shall be made by the district courts.
Violation of the guarantees set forth in Article 16, in criminal matters, and Articles 19 and 20 may be taken before the court above the one where it was committed, or before the appropriate district judge, and in either case the decision shall be rendered in accordance with the terms prescribed in section VIII.

If the district judge resides in the same place as the responsible authority, the law shall specify the judge before whom the writ of amparo is to be presented, and that judge may provisionally suspend the act in question, in those cases and under the terms established in the same law.

The law shall specify the terms and cases in which the precedents of the courts of the federal judicial branch are binding, as well as the requirements for their modification.

If the full circuit courts sustain contradictory opinions in amparo cases within their jurisdiction, the ministers of the Supreme Court of Justice, the Attorney General of the Republic, or those courts, may denounce the contradiction before the appropriate section, to decide which opinion shall prevail.

When the sections of the Supreme Court of Justice sustain contradictory opinions in cases of amparo within their jurisdiction, any one section or the Attorney General of the Republic may denounce the contradiction before the Supreme Court of Justice, which, sitting as a full court, shall decide which opinion shall prevail. Both in this instance and in the case provided for in the preceding paragraph, the decision rendered shall be solely for the effect of fixing the precedent and shall not affect the concrete juridical situation deriving from contradictory judgments in the case in which they were rendered.

When the contested act originated with civil or administrative authorities, and provided that the constitutionality of a law is not involved, proceedings will be discontinued by inactivity of the aggrieved party in those cases and according to terms indicated in the law regulating this article.
The Attorney General of the Republic or an agent of the federal public ministry appointed for the purpose, shall be a party in all suits in amparo, but they may abstain from intervening in such cases, if the matter in question lacks public interest, in their opinion.
If after amparo is granted, the responsible official persists in repetition of the contested act or attempts to evade the decision of the federal authority, he shall be immediately removed from office and taken before the appropriate District Judge.
The responsible authority will be taken before the appropriate authority whenever he fails to suspend the act when bound to do so, and when he posts bond that is invalid or insufficient, and in such cases the responsible authority and bondsman are jointly and severally liable.
Bailiffs and jailers who do not receive an authorized copy of the order of imprisonment of an arrested person within the seventy-two hours prescribed by Article 19, counted from the day the party was at the disposal of the judge, must notify the judge of this fact at the end of such period, and if the order is not received within three hours' the prisoner shall be released.

Anyone violating the article cited in this provision will be immediately turned over to a competent authority.

Likewise, anyone who, after an arrest, does not take the arrested person before a judge within twenty-four hours, shall himself be turned over to such authority or his agent.

If the detention takes place outside the locality in which the judge resides, sufficient time is to be added to the above period to cover the distance involved.

TITLE IV

Responsibilities of Public Officials

Article 108. Senators and deputies of the Congress of the Union, magistrates of the Supreme Court of Justice of the Nation, secretaries of the Cabinet, and the Attorney General of the Republic are liable for common crimes that they may commit during their term of office, and also for crimes, offenses, or omissions that they incur in the exercise of their office.

Governors of the States and deputies of the local legislatures are liable for violations of the federal Constitution and laws.

The President of the Republic, during his term of office, may be impeached only for treason to the country and serious common crimes.

Article 109. If the offense is of a common order, the Chamber of Deputies acting as a grand jury shall determine, by an absolute majority of votes of its total membership, whether or not there are grounds for proceeding against the accused.

If the finding is negative, there shall be no grounds for any further proceedings; but such decision shall not be an obstacle to continuing the prosecution of the charge, whenever the accused has relinquished his immunity, since the decision of the Chamber in no way prejudges the merits of the charge.

If the finding is affirmative, the accused shall thereby be suspended from office and is immediately subject to action by the ordinary courts, excepting the case of the President of the Republic, who may be impeached only before the Chamber of Senators, as in the case of an official offense.

Article 110. Constitutional immunity shall not be enjoyed by high officials of the Federation with respect to official crimes, offenses or omissions incurred in the discharge of any office, employment or public commission which they have accepted during the period in which, according to law, they enjoy constitutional immunity. The same shall apply with respect to common crimes which they may commit during the performance of such office, employment, or commission. The procedure to be followed to institute proceedings against a high official who has resumed the exercise of his own functions is that prescribed in the preceding article

Article 111. The Senate, constituted as a grand jury, shall take cognizance of all official offenses; but it may not open the pertinent investigation without a previous bill of impeachment by the Chamber of Deputies. If after conducting such proceedings as it deems advisable and hearing the accused, the Chamber of Senators shall decide by a two-thirds majority of all its members that he is guilty, the latter shall be removed from office by virtue of such decision and disqualified from holding any other office for a period determined by law.

Whenever the law provides another penalty for the same act, the accused shall be placed at the disposal of the regular authorities, who shall judge and punish him according to such law.

In the cases governed by this article and those referred to in Article 109, the decisions of the grand jury and the findings of the Chamber of Deputies shall be final.

Any person has the right to denounce before the Chamber of Deputies the common or official offenses of high officials of the Federation Whenever the aforesaid Chamber finds that there are grounds for impeachment, it shall appoint a committee from among its members to sustain before the Senate the charges brought.

As soon as possible, the Congress of the Union shall enact a law covering the responsibilities of all officials and employees of the Federation and of the Federal District and Territories, defining as official offenses or misdemeanors all acts or omissions that may result in injury to public interests or to the proper conduct of business, even though they have not been considered previously as wrongful acts These offenses or misdemeanors shall always be tried before a jury of the people, in the manner established by Article 20 for offenses of the press.

The President of the Republic may request from the Chamber of Deputies the removal, for bad conduct, of any ministers of the Supreme Court of Justice, of circuit magistrates, of district judges, of the magistrates of the superior court of justice of the Federal District and of the Territories, and of the judges of common rank in the Federal District and Territories. In these cases, if the Chamber of Deputies first and the Senators thereafter decide by an absolute majority of votes that the request is justified, the accused official shall be removed from office immediately, independently of the legal liability that may have been incurred, and the Executive shall proceed with a new appointment.

The President of the Republic, before asking the chambers for the removal of any judicial official, shall grant a hearing to the latter privately in order to conscientiously appraise the justification of such request.⁽⁴⁵⁾

Article 112. The offender cannot be pardoned after a verdict of guilty is pronounced for official offenses.

Article 113. Responsibility for official offenses or misdemeanors may be exacted only during the term of office of the official in question, and within one year thereafter.

Article 114. There are no privileges or immunities for any public official with respect to claims of a civil character.

Article 123.⁽⁵⁰⁾ The Congress of the Union, without contravening the following basic principles, shall formulate labor laws which shall apply to:

I. The maximum duration of work for one day shall be eight hours.

II. ⁽⁵¹⁾ The maximum duration of nightwork shall be seven hours. The following are prohibited: unhealthful or dangerous work by women and by minors under sixteen years of age; industrial nightwork by either of these classes; work by women in commercial establishments after ten o'clock at night and work (of any kind) by persons under sixteen after ten o'clock at night.

During the nursing period they shall have two special rest periods each day, of a half hour each, for nursing their infants.

VI. The minimum wage to be received by a worker shall be general or according to occupation. The former shall govern in one or more economic zones; the latter shall be applicable to specified branches of industry or commerce or to special occupations, trades, or labor.

The general minimum wage must be sufficient to satisfy the normal material, social, and cultural needs of the head of a family and to provide for the compulsory education of his children. The occupational minimum wage shall be fixed by also taking into consideration the conditions of different industrial and commercial activities

Farm workers shall be entitled to a minimum wage adequate to their needs.

The minimum wage is to be fixed by regional committees, composed of representatives of the workers, employers, and the Government, and will be subject to approval by a national committee, organized in the same manner as the regional committees.

VIII. The minimum wage shall be exempt from attachment, compensation, or deduction.

A national committee, composed of representatives of workers, employers, and the Government, shall fix the percentage of profits to be distributed among workers.
The national committee shall undertake research and make necessary and appropriate studies in order to become acquainted with the general conditions of the national economy. It shall also take into consideration the need to promote the industrial development of the country, the reasonable return that should be obtained by capital, and the necessary reinvestment of capital.
The committee may revise the fixed percentage whenever new studies and research so justify.
The law may exempt newly established enterprises from the obligation of sharing profits for a specified and limited number of years for exploration work and other activities so justified by their nature or peculiar conditions.
To determine the amount of the profits of each enterprise the basis to be taken is the taxable income according to the provisions of the income tax law. Workers may submit to the appropriate office of the Secretariat of Finance and Public Credit any objections they may deem pertinent, in accordance with procedure indicated in the law.
The right of workers to participate in profits does not imply the power to intervene in the direction or administration of an enterprise.

X. Wages must necessarily be paid in money of legal tender and cannot be paid in goods, promissory notes, or any other token intended as a substitute for money.

XI. Whenever, due to extraordinary circumstances, the regular working hours of a day must be increased, one hundred percent shall be added to the amount for normal hours of work as remuneration for the overtime. Overtime work may never exceed three hours a day nor three times consecutively. Persons under sixteen years of age and women of any age may not be admitted to this kind of labor.

XII. In any agricultural, industrial, or mining enterprise or in any other kind of work, employers shall be obliged to furnish workmen comfortable and hygienic living quarters for which they may collect rent that shall not exceed one half percent monthly of the assessed valuation of the property. They also must establish schools, hospitals, and any other services necessary to the community. If the enterprise is situated within a town and employs more than one hundred workers, it shall be responsible for the first of the above obligations.

Establishments for the sale of intoxicating liquors and houses for games of chance are prohibited in all work centers.

XIV. Employers shall be responsible for labor accidents and for occupational diseases of workers, contracted because of or in the performance of their work or occupation; therefore, employers shall pay the corresponding indemnification whether death or only temporary or permanent incapacity to work has resulted, in accordance with what the law prescribes. This responsibility shall exist even if the employer contracts for the work through an intermediary.

XV. An employer shall be required to observe, in the installation of his establishments, the legal regulations on hygiene and health, and to adopt adequate measures for the prevention of accidents in the use of machines, instruments, and materials of labor, as well as to organize the same in such a way as to ensure the greatest possible guarantee for the health and safety of workers as is compatible with the nature of the work, under the penalties established by law in this respect.

XVI. Both employers and workers shall have the right to organize for the defense of their respective interests, by forming unions, professional associations, etc.

XVII. The laws shall recognize strikes and lockouts as rights of workmen and employers.

XVIII. Strikes shall be legal when they have as their purpose the attaining of an equilibrium among the various factors of production, by harmonizing the rights of labor with those of capital. In public services it shall be obligatory for workers to give notice ten days in advance to the Board of Conciliation and Arbitration as to the date agreed upon for the suspension of work. Strikes shall be considered illegal only when the majority of strikers engage in acts of violence against persons or property, or in the event of war, when the workers belong to establishments or services of the Government.

XX. Differences or disputes between capital and labor shall be subject to the decisions of a Board of Conciliation and Arbitration, consisting of an equal number of workmen and employers, with one from the Government.

XXI. ⁽⁵³⁾ If an employer refuses to submit his differences to arbitration or to accept the decision rendered by the Board, the labor contract shall be considered terminated and he shall be obliged to indemnify the worker to the amount of three months' wages and shall incur any liability resulting from the dispute. This provision shall not be applicable in the case of actions covered in the following section. If the refusal is made by workers, the labor contract shall be considered terminated.

XXII. ⁽⁵⁴⁾ An employer who dismisses a worker without justifiable cause or because he has entered an association or union, or for having taken part in a lawful strike, shall be required, at the election of the worker, either to fulfill the contract or to indemnify him to the amount of three months' wages. The law shall specify those cases in which the employer may be exempted from the obligation of fulfilling the contract by payment of an indemnity. He shall also have the obligation to indemnify a worker to the amount of three months' wages, if the worker leaves his employment due to lack of honesty on the part of the employer or because of ill treatment from him, either to himself or to his wife, parents, children, or brothers and sisters. An employer may not relieve himself of this responsibility when the ill treatment is attributable to his subordinates or members of his family acting with his consent or tolerance.

XXIII. Credits in favor of workers for wages or salary earned within the last year, and for indemnity compensation, shall have priority over all other obligations in the event of receivership or bankruptcy.

XXIV. A worker alone shall be responsible for debts contracted by himself and payable to his employer, his associates, members of his family, or dependents, and in no case and for no purpose may payment be exacted from members of the worker's family, nor are these debts demandable for an amount exceeding the wages of the worker for one month.

XXV. Services of employment placement for workers shall be gratuitous, whether such service is performed by a municipal office, labor exchange, or any other official or private institution.

XXVI. Every labor contract made between a Mexican and a foreign employer must be notarized by a competent municipal authority and countersigned by the consul of the nation to which the worker intends to go, because, in addition to the ordinary stipulations, it shall be clearly specified that the expenses of repatriation shall be borne by the contracting employer.

XXVII. The following conditions shall be considered null and void and not binding on the contracting parties, even if expressed in the contract:

Those that stipulate a day's work that is inhuman because it is obviously excessive, considering the kind of work;
Those that fix wages that are not remunerative, in the judgment of Boards of Conciliation and Arbitration;

Those that permit the retention of wages as a fine;
Those that constitute a waiver by the worker of indemnification to which he is entitled due to labor accidents or occupational diseases, damages occasioned by the nonfulfillment of the contract, or by being discharged;
All other stipulations that imply waiver of any right designed to favor the worker in the laws of protection and assistance for workmen;

XXVIII. The laws shall determine what property constitutes the family patrimony, property that shall be inalienable, not subject to encumbrances of attachment, and that shall be transmissible by inheritance with simplification of the formalities of succession.

XXIX. Enactment of a social security law shall be considered of public interest and it shall include insurance against disability, on life, against involuntary work stoppage, against sickness and accidents, and other forms for similar purposes;

XXX. Likewise, cooperative societies established for the construction of low-cost and hygienic houses to be purchased on installments by workers, shall be considered of social utility;

TITLE VII

General Considerations

Article 124. The powers not expressly granted by this Constitution to federal officials are understood to be reserved to the States.

Article 126. No payment may be made that is not included in the budget or provided for by a subsequent law.

Article 127. The President of the Republic, the members of the Supreme Court of Justice, the deputies and senators, and other elective public officials of the Federation shall receive a compensation for their services that shall be specified by law and paid by the federal Treasury. This compensation cannot be refused and any law that increases or decreases it shall not take effect during the term in which an official holds office.

Article 128. Every public official, without exception of any kind, before taking possession of his office, shall take an affirmation to uphold the Constitution and the laws emanating therefrom.

Article 130.⁽⁵⁸⁾ The federal powers shall exercise the supervision required by law in matters relating to religious worship and outward ecclesiastical forms. Other authorities shall act as auxiliaries of the Federation.

Congress cannot enact laws establishing or prohibiting any religion.

Marriage is a civil contract. This and other acts of a civil nature concerning persons are within the exclusive competence of civil officials and authorities, in the manner prescribed by law, and shall have the force and validity defined by said law.

A simple promise to tell the truth and to fulfill obligations that are contracted is binding on the one who so promises, and in the event of failure to do so, he shall be subject to the penalties that the law prescribes for this purpose.

The law does not recognize any personality in religious groups called churches.

Ministers of denominations shall be considered as persons who practice a profession and shall be directly subject to the laws enacted on such matters.

Only the legislatures of the States shall have the power to determine the maximum number of ministers of denominations necessary for local needs.

To practice the ministry of any denomination in the United Mexican States it is necessary to be a Mexican by birth.

Ministers of denominations may never, in a public or private meeting constituting an assembly, or in acts of worship or religious propaganda, criticize the fundamental laws of the country or the authorities of the Government, specifically or generally.

5. In Spanish law, when the evidence was inconclusive, the matter could be disposed of by an order of absolución de la instancia, which operated as a dismissal but not as a judgment for or against either party in a civil case, or as an acquittal or conviction in a criminal case. Hence, upon discovery of more evidence the case might be revived. Similar to the Scotch verdict of not proved, and to the Roman non liquet (it does not appear clear). Escriche Diccionario.
