Facts
- The United States issued a war-risk policy insuring Standard Oil’s steam tanker John Worthington against “all consequences of hostilities or warlike operations.”
- On December 16, 1942, the John Worthington collided near the approaches to New York Harbor with the YMS-12, a U.S. Navy minesweeper engaged in minesweeping operations.
- The parties stipulated that both vessels were at fault for failing to follow applicable rules of good seamanship under the circumstances.
- The United States conceded minesweeping is a “warlike operation,” but disputed that the collision was a covered “consequence” of that operation under the policy.
- Standard Oil argued that collision with a moving naval vessel engaged in a warlike operation established coverage as a matter of law, relying in part on English marine insurance decisions.
Issues
- Whether, as a matter of law, a war-risk policy covering “all consequences of hostilities or warlike operations” covers a wartime collision between the insured vessel and a naval minesweeper engaged in minesweeping when both vessels are at fault.
- Whether coverage instead depends on proof that the warlike operation was the proximate (predominating and determining) cause of the collision, making causation a factual question.
Decision
- The Supreme Court affirmed the Second Circuit’s judgment denying recovery.
- The Court held that the policy language does not make the war-risk underwriter liable as a matter of law for any collision involving a naval vessel engaged in a warlike operation.
- To shift a collision loss from ordinary marine risk to war-risk coverage, the warlike operation must be the proximate cause of the collision.
- Because certiorari addressed only the policy’s legal construction, the Court did not revisit the lower courts’ conflicting fact findings and accepted the Second Circuit’s determination that proximate causation was not shown.
Legal Principles
- A collision is ordinarily a marine risk; war-risk coverage for “all consequences of” warlike operations applies only when the warlike operation is the proximate, predominating, and determining cause of the loss.
- The mere presence or involvement of a warship engaged in a warlike operation does not establish war-risk liability without proof of proximate causation.
- Interpretation of marine insurance contracts may consider English decisions, but U.S. courts are not bound to follow them automatically.
- When Supreme Court review is limited to a legal question, factual determinations by the court below are not reweighed absent review of those findings.
Conclusion
The Court ruled that war-risk insurance covering “all consequences of hostilities or warlike operations” does not automatically cover a collision with a naval minesweeper; the insured must prove the warlike operation proximately caused the collision, and the Court left intact the appellate finding that such causation was not established.
