If in the case submitted to the commissioners either party shall have specified or alluded to any report or document in its own exclusive possession, without annexing a copy, such party shall be bound, if the other party thinks proper to apply for it, to furnish that party with a copy thereof; and either party may call upon the other, through the commissioners, to produce the originals or certified copies of any papers adduced as evidence, giving in each instance such reasonable notice as the commissioners may require.

The case on either side shall be closed within a period of six months from the date of the organization of the commission, and the commissioners shall be requested to give their award as soon as possible thereafter.  The aforesaid period of six months may be extended for three months in case of a vacancy occurring among the commissioners under the circumstances contemplated in Article XXIII of this treaty.

  Governments in equal moieties.
