When an investor submits a claim to arbitration under a treaty that falls within the scope of an existing, contractual forum-selection clause between it and the host State, which prevails: the agreement to arbitrate under the treaty or the contractual clause? This is a vexed and commonly arising question. This article argues that by placing it in the context of both private and public international law and reasoning from first principles it is possible to arrive at a coherent, reliable and satisfactory approach. The true question is whether the contractual clause is a waiver of the investor's right to recourse to an investment tribunal.
