CCPR/C/21/Rev.1/Add.6 page 4 10. The Committee has further examined whether categories of reservations may offend the "object and purpose" test. In particular, it falls for consideration as to whether reservations to the non-derogable provisions of the Covenant are compatible with its object and purpose. While there is no hierarchy of importance of rights under the Covenant, the operation of certain rights may not be suspended, even in times of national emergency. This underlines the great importance of non-derogable rights. But not all rights of profound importance, such as articles 9 and 27 of the Covenant, have in fact been made non-derogable. One reason for certain rights being made non-derogable is because their suspension is irrelevant to the legitimate control of the state of national emergency (for example, no imprisonment for debt, in article 11). Another reason is that derogation may indeed be impossible (as, for example, freedom of conscience). At the same time, some provisions are non-derogable exactly because without them there would be no rule of law. A reservation to the provisions of article 4 itself, which precisely stipulates the balance to be struck between the interests of the State and the rights of the individual in times of emergency, would fall in this category. And some non-derogable rights, which in any event cannot be reserved because of their status as peremptory norms, are also of this character - the prohibition of torture and arbitrary deprivation of life are examples. 4/ While there is no automatic correlation between reservations to non-derogable provisions, and reservations which offend against the object and purpose of the Covenant, a State has a heavy onus to justify such a reservation. 11. The Covenant consists not just of the specified rights, but of important supportive guarantees. These guarantees provide the necessary framework for securing the rights in the Covenant and are thus essential to its object and purpose. Some operate at the national level and some at the international level. Reservations designed to remove these guarantees are thus not acceptable. Thus, a State could not make a reservation to article 2, paragraph 3, of the Covenant, indicating that it intends to provide no remedies for human rights violations. Guarantees such as these are an integral part of the structure of the Covenant and underpin its efficacy. The Covenant also envisages, for the better attainment of its stated objectives, a monitoring role for the Committee. Reservations that purport to evade that essential element in the design of the Covenant, which is also directed to securing the enjoyment of the rights, are also incompatible with its object and purpose. A State may not reserve the right not to present a report and have it considered by the Committee. The Committee’s role under the Covenant, whether under article 40 or under the Optional Protocols, necessarily entails interpreting the provisions of the Covenant and the development of a jurisprudence. Accordingly, a reservation that rejects the Committee’s competence to interpret the requirements of any provisions of the Covenant would also be contrary to the object and purpose of that treaty. 12. The intention of the Covenant is that the rights contained therein should be ensured to all those under a State party’s jurisdiction. To this end 4/ Reservations have been entered to both article 6 and article 7, but not in terms which reserve a right to torture or to engage in arbitrary deprivation of life.
