1. The Committee notes that article 2 of the Covenant generally leaves it to the States parties concerned to choose their method of implementation in their territories within the framework set out in that article. It recognizes, in particular, that the implementation does not depend solely on constitutional or legislative enactments, which in themselves are often not per se sufficient. The Committee considers it necessary to draw the attention of States parties to the fact that the obligation under the Covenant is not confined to the respect of human rights, but that States parties have also undertaken to ensure the enjoyment of these rights to all individuals under their jurisdiction. This aspect calls for specific activities by the States parties to enable individuals to enjoy their rights. This is obvious in a number of articles (e.g. art. 3 which is dealt with in General Comment 4 below), but in principle this undertaking relates to all rights set forth in the Covenant.

2. In this connection, it is very important that individuals should know what their rights under the Covenant (and the Optional Protocol, as the case may be) are and also that all administrative and judicial authorities should be aware of the obligations which the State party has assumed under the Covenant. To this end, the Covenant should be publicized in all official languages of the State and steps should be taken to familiarize the authorities concerned with its contents as part of their training. It is desirable also to give publicity to the State party's cooperation with the Committee.
