For all notices which the Tribunal has to serve in the territory of a third Contracting Power, the Tribunal shall apply direct to the Government of that Power. The same rule applies in the case of steps being taken to procure evidence on the spot.

The requests for this purpose are to be executed as 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 them calculated to impair its own sovereign rights or its safety.

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