Abstract

The notion of reservation is defined in Art 2 para 1 lit d of the Convention. According to this definition, “reservation” means “a unilateral statement, however phrased or named, made by a State, when signing, ratifying, accepting, approving or acceding to a treaty, whereby it purports to exclude or to modify the legal effect of certain provisions of the treaty in their application to that State.” Before the adoption of the Convention, several other definitions had been used in practice and discussed in literature. These definitions are, however, largely similar to the definition given in the Convention. The definition thus reflects the customary law notion of a reservation.

    An example may be found in the original version of Art 32 para 1 lit b of the 1989 European Convention on Transfrontier Television ETS 132 (the provision has been amended in 2002): “At the time of signature or when depositing its instrument of ratification, acceptance, approval or accession: […] the United Kingdom may declare that it reserves the right not to fulfil the obligation, set out in Article 15, para 1, to prohibit advertisements for tobacco products, in respect of advertisements for cigars and pipe tobacco broadcast by the Independent Broadcasting Authority by terrestrial means on its territory.”; for a critical discussion of the notion of “negotiated reservations see Pellet 5th Report, UN Doc A/CN.4/508, paras 164–171 (2000).

  76. 76.

    An example for a negotiated reservation with temporary limitation may be found in Art 17 (plus Annex) of the 1973 European Convention on Civil Liability for Damage caused by Motor Vehicles ETS 73: “Belgium may, at the time of signature or when depositing its instrument of ratification or acceptance of the Convention, declare that she reserves the right to exclude from the scope of the Convention material damage to vehicles, for a period of three years from the date of the entry into force of the Convention in her respect.”; for further examples see Spilioupoulou Åkermark (1999a), pp. 499–500.

In making the declaration a State is equally free either to do so unconditionally and without limit of time for its duration, or to qualify it with conditions or reservations. In particular, it may limit its effect to disputes arising after a certain date; or it may specify how long the declaration itself shall remain in force, or what notice (if any) will be required to terminate it.”; for further details see Tomuschat (2012), MN 75 et seq.

    The provision reads: “At the time of signature, ratification or accession, any State may make reservations to articles of the Convention other than to articles 1 to 3 inclusive.”

  129. 129.

    “[…], the Court considers the view expressed by both Parties that Article 12 cannot be read as committing States to accept in advance any and every reservation to article other than Articles 1, 2 and 3 to be clearly correct. Such in interpretation of Article 12 would amount almost to a license to contracting States to write their own treaty and would manifestly go beyond the purpose of the Article. Only if the Article had authorized the making or specific reservations could parties to the Convention be understood as having accepted a particular reservation in advance. But this is not the case with Article 12, which authorizes the making or reservations to articles other than Articles 1 to 3 in quite general terms. Article 12, as the practice of a number or States recorded in Multilateral Treaties in respects of which the Secretary-General Performs Depositary Functions confirms leaves contracting States free to react in any way they think fit to a reservation made in conformity with its provisions, including refusal to accept the reservations. Whether any such reaction amounts to a mere comment, a mere reserving of position, a rejection merely of the particular reservation or a wholesale rejection of any mutual relations with the reserving State under the treaty consequently depends on the intention of the State concerned.” Delimitation of the Continental Shelf between the United Kingdom and France (United Kingdom v France) (1977) 18 RIAA 3 para 39.

    “The question of the admissibility of reservations could only be determined by reference to the terms of the treaty as a whole. As a rule it was possible to draw a distinction between the essential clauses of a treaty, which normally did not admit of reservations, and the less important clauses, for which reservations were possible.” [1962-I] YbILC 141, para 35.

    In fact, the Draft Guidelines also treated reservations concerning norms of ius cogens character in that context (see Draft Guideline 3.1.9, UN Doc A/65/10 (2010)). However, during the final drafting process the respective Guideline was for systematic reasons moved to part 4 of the Guidelines which deals with legal effects of reservations and interpretative declarations, see Oral Report by the Chairman of the Working Group on Reservations to Treaties, Vázquez Bermúdez, ILC 63rd Session, 20 May 2011, http://legal.un.org/ilc/sessions/63/pdfs/reservations_to_treaties_report_20may2011.pdf.

    “The formal requirement in para 2 of Article 64 of the Convention is essentially a supplementary condition, which must be interpreted together with para 1 of that provision. It is recalled that the latter requires a reservation to refer to “any law in force” and prohibits reservations of a general character. This concern probably underlies the existence of paragraph 2. In other words, the information requested of States making a reservation should help to avoid the possibility of reservations of a general character being made.” ECommHR Temeltasch v Switzerland App No 9116/80 (1983) 31 DR 120, 150; for a similar approach see the decision in ECtHR Belilos v Switzerland App No 10328/83, Ser A 132, para 55 (1988).

    “Inasmuch as under the Canadian constitutional system legislative jurisdiction in respect of environmental assessment is divided between the provinces and the federal government, the Government of Canada in ratifying this Convention, makes a reservation in respect of proposed activities (as defined in this Convention) that fall outside of federal legislative jurisdiction exercised in respect of environmental assessment.”, Multilateral Treaties Deposited with the Secretary General (2009), UN Doc ST/LEG/SER.E/26, Vol III 678 (ch XXVII.4).

    See, for instance, the Austrian Declaration referring to reservations by Guatemala to the VCLT according to which “Austria is of the view that the Guatemalan reservations refer almost exclusively to general rules of [the said Convention] many of which are solidly based on international customary law. The reservations could call into question well-established and universally accepted norms. Austria is of the view that the reservations also raise doubts as to their compatibility with the object and purpose of the [said Convention]. Austria therefore objects to these reservations.” Multilateral Treaties Deposited with the Secretary General (2009), UN Doc ST/LEG/SER.E/26, Vol III 531 (ch XXIII.1).

    See, for instance, the objection entered by Norway: “A reservation by which a State Party limits its responsibilities under the Convention by invoking general principles of national law may create doubts about the commitments of the reserving state to the object and purpose of the Convention and, moreover, contribute to undermining the basis of international treaty law. It is in the common interest of states that treaties to which they have chosen to become parties also are respected, as to object and purpose, by all parties. The Government of Norway, therefore, objects to this reservation.” Multilateral Treaties Deposited with the Secretary General (2009), UN Doc ST/LEG/SER.E/26, Vol I 404 (ch IV.11).

The object and purpose of the Covenant is to create legally binding standards for human rights by defining certain civil and political rights and placing them in a framework of obligations which are legally binding for those States which ratify; and to provide an efficacious supervisory machinery for the obligations undertaken.”

    “It is clear that the first Optional Protocol is itself an international treaty, distinct from the Covenant but closely related to it. Its object and purpose is to recognize the competence of the Committee to receive and consider communications from individuals who claim to be victims of a violation by a State Party of any of the rights in the Covenant. States accept the substantive rights of individuals by reference to the Covenant, and not the first Optional Protocol. The function of the first Optional Protocol is to allow claims in respect of those rights to be tested before the Committee. Accordingly, a reservation to an obligation of a State to respect and ensure a right contained in the Covenant, made under the first Optional Protocol when it has not previously been made in respect of the same rights under the Covenant, does not affect the State’s duty to comply with its substantive obligation. A reservation cannot be made to the Covenant through the vehicle of the Optional Protocol but such a reservation would operate to ensure that the State’s compliance with that obligation may not be tested by the Committee under the first Optional Protocol. And because the object and purpose of the first Optional Protocol is to allow the rights obligatory for a State under the Covenant to be tested before the Committee, a reservation that seeks to preclude this would be contrary to the object and purpose of the first Optional Protocol, even if not of the Covenant.” General Comment No 24, 4 November 1994, UN Doc CCPR/C/21/Rev.1/Add.6, para 13.

    For that reason, the ILC adopted Draft Guideline 2.1.8 according to which in case of a reservation which in the opinion of the depositary “is manifestly invalid, the depositary shall draw the attention of the author of the reservation to what, in the depositary’s view, constitutes the grounds for the invalidity of the reservation. If the author of the reservation maintains the reservation, the depositary shall communicate the text of the reservation to the signatory States and international organizations and to the contracting States and international organizations and, where appropriate, the competent organ of the international organization concerned, indicating the nature of legal problems raised by the reservation.”; see notably the commentary on that Draft Guideline in ILC Report 2006, 359–361.
