Dan Svantesson has introduced an important proposal to reformulate the way we allocate jurisdiction in the international community. Rather than asking whether a proposed assertion of jurisdiction falls into one of the canonical principles identified in the Harvard Research Draft Convention on Jurisdiction with Respect to Crime of 1935, Svantesson proposes to subject claims of jurisdiction to three “core” principles: (1) whether there is a substantial connection between the matter and the State seeking to exercise jurisdiction; (2) whether the State seeking to exercise jurisdiction has a legitimate interest in the matter; and (3) whether the claim of jurisdiction is reasonable given the balance between the state’s interests and other interests that might be asserted. He sees the first two of these as being implicit in the Harvard Draft paradigm, and the third a helpful addition to resolve conflicts in an increasingly interdependent world.
