For these reasons the Committee has deemed it useful to address in a General Comment the issues of international law and human rights policy that arise. The General Comment identifies the principles of international law that apply to the making of reservations and by reference to which their acceptability is to be tested and their purport to be interpreted. It addresses the role of States Parties in relation to the reservations of others. It further addresses the role of the Committee itself in relation to reservations. And it makes certain recommendations to present States Parties for a reviewing of reservations and to those States that are not yet parties about legal and human rights policy considerations to be borne in mind should they consider ratifying or acceding with particular reservations.
