The Supreme Court unanimously ruled that choice-of-law provisions in maritime contracts are presumptively enforceable under federal maritime law, overturning a lower court decision that allowed state public policy to invalidate them.
Who it affects
Maritime insurers and vessel owners can generally rely on the law named in their contracts. For example, a yacht policy choosing New York law will not ordinarily be set aside because another state has a conflicting policy.
