(1) A time limit prescribed by these Rules may only be extended by agreement of the parties. A procedural step taken or document received after the expiry of such time limit shall be disregarded, unless the parties agree otherwise or the Tribunal decides that there are special circumstances justifying the failure to meet the time limit.

(2) A time limit fixed by the Tribunal or the Secretary-General may be extended by agreement of the parties or by the Tribunal, or the Secretary-General if applicable, upon reasoned application by either party made prior to its expiry. A procedural step taken or a document received after the expiry of such time limit shall be disregarded, unless the parties agree otherwise or the Tribunal, or the Secretary-General if applicable, decides that there are special circumstances justifying the failure to meet the time limit.

(3) The Tribunal may delegate the power to extend time limits to its President.
