CCPR/C/21/Rev.1/Add. 13 page 3 5. The article 2, paragraph 1, obligation to respect and ensure the rights recognized by in the Covenant has immediate effect for all States parties. Article 2, paragraph 2, provides the overarching framework within which the rights specified in the Covenant are to be promoted and protected. The Committee has as a consequence previously indicated in its General Comment 24 that reservations to article 2, would be incompatible with the Covenant when considered in the light of its objects and purposes. 6. The legal obligation under article 2, paragraph 1, is both negative and positive in nature. States Parties must refrain from violation of the rights recognized by the Covenant, and any restrictions on any of those rights must be permissible under the relevant provisions of the Covenant. Where such restrictions are made, States must demonstrate their necessity and only take such measures as are proportionate to the pursuance of legitimate aims in order to ensure continuous and effective protection of Covenant rights. In no case may the restrictions be applied or invoked in a manner that would impair the essence of a Covenant right. 7. Article 2 requires that States Parties adopt legislative, judicial, administrative, educative and other appropriate measures in order to fulfil their legal obligations. The Committee believes that it is important to raise levels of awareness about the Covenant not only among public officials and State agents but also among the population at large. 8. The article 2, paragraph 1, obligations are binding on States [Parties] and do not, as such, have direct horizontal effect as a matter of international law. The Covenant cannot be viewed as a substitute for domestic criminal or civil law. However the positive obligations on States Parties to ensure Covenant rights will only be fully discharged if individuals are protected by the State, not just against violations of Covenant rights by its agents, but also against acts committed by private persons or entities that would impair the enjoyment of Covenant rights in so far as they are amenable to application between private persons or entities. There may be circumstances in which a failure to ensure Covenant rights as required by article 2 would give rise to violations by States Parties of those rights, as a result of States Parties’ permitting or failing to take appropriate measures or to exercise due diligence to prevent, punish, investigate or redress the harm caused by such acts by private persons or entities. States are reminded of the interrelationship between the positive obligations imposed under article 2 and the need to provide effective remedies in the event of breach under article 2, paragraph 3.
