The parties can reserve in the 'Compromis' the right to demand the revision of the Award.

In this case and unless there be an Agreement to the contrary, the demand must be addressed to the Tribunal which pronounced the Award. It can only be made on the ground of the discovery of some new fact calculated to exercise a decisive influence upon the Award and which was unknown to the Tribunal and to the party which demanded the revision at the time the discussion was closed.

Proceedings for revision can only be instituted by a decision of the Tribunal expressly recording the existence of the new fact, recognizing in it the character described in the preceding paragraph, and declaring the demand admissible on this ground.

The 'Compromis' fixes the period within which the demand for revision must be made.
