The States Parties to the present Convention,

Recalling resolutions of the General Assembly of the United Nations 3 (I) of 13 February 1946 and 170 (II) of 31 October 1947 on the extradition and punishment of war criminals, resolution 95 (I) of 11 December 1946 affirming the principles of international law recognized by the Charter of the International Military Tribunal, Nuremberg, and the judgement of the Tribunal, and resolutions 2184 (XXI) of 12 December 1966 and 2202 (XXI) of 16 December 1966 which expressly condemned as crimes against humanity the violation of the economic and political rights of the indigenous population on the one hand and the policies of apartheid on the other,

Recalling resolutions of the Economic and Social Council of the United Nations 1074 D (XXXIX) of 28 July 1965 and 1158 (XLI) of 5 August 1966 on the punishment of war criminals and of persons who have committed crimes against humanity,

Noting that none of the solemn declarations, instruments or conventions relating to the prosecution and punishment of war crimes and crimes against humanity made provision for a period of limitation,

Considering that war crimes and crimes against humanity are among the gravest crimes in international law,

Convinced that the effective punishment of war crimes and crimes against humanity is an important element in the prevention of such crimes, the protection of human rights and fundamental freedoms, the encouragement of confidence, the furtherance of co-operation among peoples and the promotion of international peace and security,

Noting that the application to war crimes and crimes against humanity of the rules of municipal law relating to the period of limitation for ordinary crimes is a matter of serious concern to world public opinion, since it prevents the prosecution and punishment of persons responsible for those crimes,

Recognizing that it is necessary and timely to affirm in international law, through this Convention, the principle that there is no period of limitation for war crimes and crimes against humanity, and to secure its universal application,

Have agreed as follows:
