Decision: Southwest Marine, Inc. v. Gizoni, 502 U.S. 81 (1991).

A shipyard job title did not end this worker’s right to present a Jones Act claim. Byron Gizoni repaired ships, but he also worked on and rode a group of floating platforms. The Supreme Court held that ship-repair work did not automatically exclude him from seaman status. It affirmed the reversal of summary judgment against him, not a final finding that he was a seaman. Southwest Marine, Inc. v. Gizoni, 502 U.S. 81, 83–85, 92 (1991).

The job title did not answer the coverage question

The San Diego shipyard used unpowered floating platforms to carry equipment and support repair crews. Tugboats moved them between repair sites. Gizoni rode the platforms, sometimes acted as a lookout or signaled the tug operator, and handled lines securing them to ships. He was injured when his foot broke through a sheet covering a deck opening while a platform transported a rudder. Gizoni, 502 U.S. at 83–84.

The Longshore and Harbor Workers’ Compensation Act lists ship repair among covered occupations but excludes vessel masters and crew members. That crew exclusion preserves the Jones Act route for a worker who actually qualifies as a seaman. The employer could not turn the occupational list into a rule that every ship repairman must use Longshore benefits exclusively. Gizoni, 502 U.S. at 86–89.

Seaman status depended on work and vessel relationship

The parties disputed whether the platforms were vessels in navigation and whether Gizoni had a sufficient employment connection to them. Those factual disputes mattered. The Court also rejected the premise that a seaman must help navigate: Doing the ship’s work can qualify, provided the required vessel connection exists. Gizoni, 502 U.S. at 87–89, 92 & note 6.

Receiving Longshore benefits did not automatically preclude suit

Gizoni had received medical and compensation payments under the Longshore Act before filing suit. The Court distinguished voluntary payments without a formal award from an actual litigated coverage decision: Accepting those payments did not itself bar the Jones Act claim. It also rejected a rule requiring the court to await an agency coverage determination first. This does not decide the effect of a different worker’s formal award or settlement; keep that document separate from a payment history. Gizoni, 502 U.S. at 90–92.

Nor did the decision promise two recoveries for the same loss. The Court relied on the statutory credit mechanism in discussing why accepting benefits should not force an election between disputed coverage theories. Gizoni, 502 U.S. at 91–92 & note 5.

Summary judgment against the Jones Act claim was improper

The Supreme Court affirmed the Ninth Circuit’s judgment allowing the claim to proceed. Gizoni still had to establish seaman status and the merits of his claim. For a present claim, also apply later authority: Chandris, Inc. v. Latsis, 515 U.S. 347, 368–369 (1995), requires a connection to a vessel in navigation, or an identifiable group of vessels, that is substantial in both duration and nature. Gizoni removes a job-title barrier; it does not supply a complete present-day coverage test.

Key takeaways

• Identify every platform or craft and analyze whether it is a vessel.
• Measure the worker’s duties, duration, and connection to the vessel or fleet.
• Separate voluntary benefit checks from any formal compensation award, release or adjudicated coverage decision.
• Apply current Jones Act and Longshore coverage precedent to the complete facts.

General information only, not legal advice. Maritime status, the effect of a prior award and filing deadlines require review of the complete record and governing law.
