Article 51 of the Rome Statute of the International Criminal Court proposes rules of procedure and evidence to be followed in the International Criminal Court.
In urgent cases, if rules do not provide for a specific situation, judges may formulate provisional rules until adopted, amended or rejected at the next session. The rules of procedure and evidence, amendments and any provisional rule should be consistent with the statute. If there is any conflict between the statute and the rules of procedure and evidence, then the statute should prevail.
