The proceedings shall be conducted in such order as the commissioners
appointed under Articles XXII and XXIII of this treaty shall
determine. They shall be bound to receive such oral or written
testimony as either Government may present. If either party shall
offer oral testimony, the other party shall have the right of
cross-examination, under such rules as the commissioners shall
prescribe.
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.
