Article Art. 51
Rules of Procedure and Evidence

1.

The Rules of Procedure and Evidence shall enter into force upon adoption by a two-thirds majority of the members of the Assembly of States Parties.

2.

Amendments to the Rules of Procedure and Evidence may be proposed by:

(a)

Any State Party;

(b)

The judges acting by an absolute majority; or

(c)

The Prosecutor.
Such amendments shall enter into force upon adoption by a two-thirds majority of the members of the Assembly of States Parties.

3.

After the adoption of the Rules of Procedure and Evidence, in urgent cases where the Rules do not provide for a specific situation before the Court, the judges may, by a two-thirds majority, draw up provisional Rules to be applied until adopted, amended or rejected at the next ordinary or special session of the Assembly of States Parties.

4.

The Rules of Procedure and Evidence, amendments thereto and any provisional Rule shall be consistent with this Statute.
