Human Rights Committee, General Comment 5, Article 4 (Thirteenth session, 1981). Compilation of General Comments and General Recommendations Adopted by Human Rights Treaty Bodies, U.N. Doc. HRI/GEN/1/Rev.1 at 5 (1994)
2. States parties have generally indicated the mechanism provided in their legal systems for the declaration of a state of emergency and the applicable provisions of the law governing derogations. However, in the case of a few States which had apparently derogated from Covenant rights, it was unclear not only whether a state of emergency had been officially declared but also whether rights from which the Covenant allows no derogation had in fact not been derogated from and further whether the other States parties had been informed of the derogations and of the reasons for the derogations.
3. The Committee holds the view that measures taken under article 4 are of an exceptional and temporary nature and may only last as long as the life of the nation concerned is threatened and that, in times of emergency, the protection of human rights becomes all the more important, particularly those rights from which no derogations can be made. The Committee also considers that it is equally important for States parties, in times of public emergency, to inform the other States parties of the nature and extent of the derogations they have made and of the reasons therefor and, further, to fulfil their reporting obligations under article 40 of the Covenant by indicating the nature and extent of each right derogated from together with the relevant documentation.
