A treaty breach does not automatically suspend or terminate treaty relations, however. It depends on how the other parties regard the breach and how they resolve to respond to it. Sometimes treaties will provide for the seriousness of a breach to be determined by a tribunal or other independent arbiter. An advantage of such an arbiter is that it prevents a party from prematurely and perhaps wrongfully suspending or terminating its own obligations due to another's alleged material breach.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): Does a material breach necessarily suspend or terminate treaty relations?
does not
