reservation to treaty

English · International law

Meaning. A unilateral statement by which a State excludes or modifies the effect of certain treaty provisions for itself.

Article 2(1)(d) of the Vienna Convention on the Law of Treaties, 1969 defines a reservation as a unilateral statement, however phrased or named, made by a State when signing, ratifying, accepting, approving or acceding to a treaty, by which it purports to exclude or modify the legal effect of certain provisions in their application to that State.

Under Article 19, a reservation is not allowed if the treaty prohibits it, if it permits only specified reservations, or if it is incompatible with the object and purpose of the treaty. This compatibility test comes from the ICJ's advisory opinion on Reservations to the Genocide Convention (1951), which rejected the old rule of unanimous acceptance. Articles 20 to 23 deal with acceptance and objection. An interpretative declaration that only clarifies meaning is not a reservation. India has entered reservations, for example to Article 1 of the ICCPR on self-determination.

Example

A reservation that excludes the core obligation of the treaty is invalid as incompatible with its object and purpose under Article 19(c).

In Indian law

  • Articles 2(1)(d) and 19–23, Vienna Convention on the Law of Treaties, 1969
  • Reservations to the Convention on Genocide, Advisory Opinion (ICJ, 1951)
