Trinidad and Tobago asked the General Assembly in December 1989 to re-open the talks for the establishment of an international criminal court and in 1994 presented a draft Statute. The General Assembly created an "ad hoc" committee for the International Criminal Court and, after hearing the conclusions, a Preparatory Committee that worked for two years (1996–1998) on the draft. Meanwhile, the United Nations created the "ad hoc" tribunals for the former Yugoslavia (ICTY) and for Rwanda (ICTR) using statutes—and amendments due to issues raised during pre-trial or trial stages of the proceedings—that are quite similar to the Rome Statute.
