9 led the U.N. International Law Commission (ILC) to engage itself, as from 1998, in the preparation of a Draft Practical Guide on Reservations to Treaties 26 (cf. infra). 29. It calls the attention, for example, to find one's extensive list of reservations, numerous and at times long, and often incongruous, of States Parties to the U.N. Covenant on Civil and Political Rights 27; and the practical problems generated by many of the reservations (also numerous and not always consistent) of the States Parties to the U.N. Convention on the Elimination of All Forms of Discrimination against Women are well-known, - to what one may add the reservations to the U.N. Convention against Torture and the Convention on the Elimination of All Forms of Racial Discrimination 28. 30. With the persistence of the inadequacy and the insufficiencies of the present system of reservations, it is not at all surprising that, firstly, multiple expressions of dissatisfaction in this respect in contemporary legal doctrine (both in general studies on the matter 29 and in respect of specific human rights treaties30); and secondly, the preparedness of human rights international supervisory organs to assert their competence to apply by themselves the criterion of the compatibility (supra) and to contribute thereby to secure the integrity of the respective human rights treaties. 31. At regional level, in its well-known judgment in the Belilos versus Switzerland case (1988) 31, locus classicus on the issue, the European Court of Human Rights considered the declaration amounting to a reservation (of a general character) of Switzerland to the European Convention on Human Rights incompatible with the object and purpose of this latter (in the light of its Article 64). On its turn, the InterAmerican Court of Human Rights, in its second and third Advisory Opinions 32, pointed out the difficulties of a pure and simple transposition from the system of reservations of the Vienna Convention on the Law of Treaties of 1969 into the domain of the international protection of human rights. 26 .

In its third Advisory Opinion on Restrictions to the Death Penalty (1983) the Court warned that the question of reciprocity as related to reservations did not fully apply vis-à-vis human rights treaties (paragraphs 62-63 and 65). Earlier, in its second Advisory Opinion on the Effect of Reservations on the Entry into Force of the American Convention (1982), the Court dismissed the postponement of the entry into force of the American Convention by application of Article 20(4) of the 1969 Vienna Convention (paragraph 34).
