Reservations to the Convention on Genocide
International Court of Justice
1951 I.C.J. 15
A dispute arose over the legal effect of reservations that several states attached when ratifying the United Nations Genocide Convention of 1948. The U.N. General Assembly asked the International Court of Justice (ICJ) for an advisory opinion on whether a state that ratifies the Convention subject to a reservation can still be considered a party if some but not all other parties object to that reservation, and if so, what effect the reservation has as between the reserving state and both the objecting and accepting parties.
Whether a State which ratifies an international convention subject to a reservation may still be regarded as a party to the convention if the reservation is objected to by one or more of the parties to the convention but not by others.
