Supplemental jurisdiction is the jurisdiction of an UNCLOS tribunal over a non-UNCLOS dispute. Its significance must not be underestimated. Almost every recent contentious dispute under UNCLOS has raised questions of supplemental jurisdiction. Nevertheless, to this day, no court, tribunal, or commentator has pieced together or even tried to piece together a comprehensive theory of supplemental jurisdiction. This Article aims to do just that.
