The bilateral and trilateral perspectives are closely related. The status and location of the actual or potential tripoint is dependent on the behavior of the three concerned states in their bilateral relationships. Conversely, the approach that parties to a bilateral agreement take to their endpoints is affected by previous bilateral agreements and by the status and location of the potential tripoint. Although the two perspectives are closely related, this report seeks to separate them for analytical clarity. Section II of this paper focuses on the bilateral perspective – that of parties, judges and arbitrators faced with two-party delimitation in the presence of a non-party, third state. Section III and the accompanying table focus on the trilateral perspective – a look from above at the current status and likely location of tripoints in light of the coastal geography and existing bilateral agreements and judicial decisions.
