For all notices to be served by the Commission in the territory of a third Contracting Power, the Commission shall apply direct to the Government of the said Power. The same rule applies in the case of steps being taken on the spot to procure evidence.

The requests for this purpose are to be executed so far as the means at the disposal of the Power applied to under its municipal law allow. They cannot be rejected unless the Power in question considers they are calculated to impair its sovereign rights or its safety.

The Commission will equally be always entitled to act through the Power on whose territory it sits.
