"3. Any party may, unless the second means of settlement is mutually adopted, submit the controversy to the Supervisory Committee of the International Council; and the Committee shall forthwith (a) name and direct a special commission to investigate and report upon the subject; (b) name and direct a commission to mediate between the parties to the controversy; or (c) direct the parties to submit the controversy to the Arbitral Tribunal for judicial settlement, it being understood that the direction to arbitrate may be made at any time in the event that investigation and mediation fail to result in a settlement of the controversy.
"Clause 2
"No party to a controversy shall assume any authority or perform any acts based upon disputed rights without authorization of the Supervisory Committee, such authorization being limited in all cases to the pendency of the controversy and its final settlement and being in no way prejudicial to the rights of the parties. An authorization thus granted by the Supervisory Committee may be modified or superseded by mutual agreement of the parties, by order of an arbitrator or arbitrators selected by the parties, or by order of the Arbitral Tribunal if the controversy is submitted to it.
"Clause 3
"The foregoing clause shall not apply to cases in which the constituted authorities of a power are unable or fail to give protection to the lives and property of nationals of another power. In the event that it becomes necessary for a power to use its military or naval forces to safeguard the lives or property of its nationals within the territorial jurisdiction of another power, the facts and reasons for such action shall be forthwith reported to the Supervisory Committee, which shall determine the course of action to be adopted in order to protect the rights of all parties, and shall notify the same to the governments involved which shall comply with such notification. In the event that a government fails to comply therewith it shall be deemed to have violated the covenant and guaranty hereinbefore set forth."
