- Where it stands
- Decided
Decided 9-0 · February 21, 2024 · Opinion by Justice Kavanaugh
- What it’s about
- 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.
