146. In any matter of whatever nature, the decision must be given within three months after being taken under advisement, unless, for a valid reason, the president of the Tribunal has granted an extension.
Where a member seized of a matter fails to give a decision within three months or, as the case may be, within such additional time as has been granted, the president may, of his own initiative or on an application by a party, withdraw the matter from the member.
Before granting an extension or withdrawing a matter from a member who has failed to give his decision within the required time, the president shall take account of the circumstances and of the interests of the parties.
