Part II : Constitution of the international prize court - Art. 27.
Art. 27. For all notices to be served, in particular on the parties, witnesses, or experts, the Court may apply direct to the Government of the State on whose territory the service is to be carried out. The same rule applies in the case of steps being taken 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 them calculated to impair its sovereign rights or its safety. If the request is complied with, the fees charged must only comprise the expenses actually incurred.
The Court is equally entitled to act through the Power on whose territory it sits.
Notices to be given to parties in the place where the Court sits may be served through the International Bureau.
