The Dispute Tribunal should also have power to make interim orders, including orders for the suspension of action in any case where there is a good prima facie case and the award of compensation or damages would be inadequate and power to summarily dismiss matters that are clearly irreceivable or are frivolous or vexatious.

“When a State claims that an injury to the person or property of one of its nationals has been committed in violation of international law, any diplomatic claim or claim before a judicial body vested in the State making the claim by reason of such injury to one of its nationals is irreceivable if the internal legal order of the State against which the claim is made provides means of redress available to the injured person which appear to be effective and sufficient, so long as the normal use of these means of redress has not been exhausted.”
