The U.S. Supreme Court ruled that choice-of-law clauses in maritime contracts are presumptively enforceable as a matter of federal law. In a unanimous opinion authored by Justice Kavanaugh, the Court ruled in favor of S&C client Great Lakes, upholding Great Lakes’ choice of New York law in its marine insurance contract. The Court’s decision will have important implications in the maritime industry, reaffirming the primacy of federal maritime law and granting greater certainty regarding the enforceability of choice-of-law provisions in maritime insurance and other contracts.
