Great Lakes Ins. SE v. Raiders Retreat Realty Co.
The Supreme Court unanimously ruled that when parties to a maritime contract — like a boat insurance policy — agree upfront on which state's law will govern disputes, federal maritime law treats that agreement as binding. A state's competing public policy cannot override it.
The decision resolves a split among the federal appeals courts and gives marine insurers and other maritime businesses a stable, predictable rule for settling which law applies before any accident or dispute ever occurs.
How it got here: The district court enforced the New York choice-of-law clause and ruled for Great Lakes; the Third Circuit vacated and remanded for a Pennsylvania public-policy analysis; the Supreme Court granted certiorari to resolve a split among the appeals courts.
The Case in Depth
What happened
Raiders Retreat Realty, a Pennsylvania company, purchased a boat insurance policy from Great Lakes Insurance, a European firm. The policy specified that New York law would govern any disputes. When Raiders' boat ran aground near Fort Lauderdale, Florida, Great Lakes denied coverage, claiming Raiders had failed to maintain the boat's fire-suppression system — a breach that, under the policy, voided coverage entirely even though the broken system had nothing to do with the accident. Raiders fought back by invoking Pennsylvania contract law rather than the New York law the policy had specified.
The question before the Court
When parties to a maritime boat-insurance contract agree in writing that a specific state's law will govern any disputes, can a different state's public policy override that agreement?
The Court's answer
Yes — federal maritime law makes choice-of-law clauses in maritime contracts presumptively enforceable, and a state's public policy is not a valid reason to override them. When parties to a maritime contract agree in writing that a specific state's law will govern their disputes, courts must honor that agreement. Only narrow exceptions apply: if the chosen law would conflict with a federal statute or an established federal maritime policy, or if the parties had no reasonable basis at all for choosing that jurisdiction's law.
The appeals court had held that Pennsylvania's insurance public policy could override the New York choice-of-law clause the parties agreed to. The Supreme Court unanimously rejected that approach. Allowing each state's public policy to override maritime choice-of-law clauses would destroy the certainty and uniformity those clauses exist to provide, and federal maritime law has no reason to prefer one state's law over another state's law in this situation.

Why it matters
Marine insurers, shipping companies, and boat owners who include choice-of-law clauses in their contracts can now rely on those clauses being honored in federal court nationwide. Insurers can more accurately price risk because they know which state's rules apply, potentially keeping marine insurance more available and affordable. States can no longer use their own insurance regulations to override the law the contracting parties specifically chose.
What changes now
By reversing the Third Circuit outright, the Supreme Court effectively reinstates the district court's original ruling, which had enforced the New York choice-of-law clause and rejected Raiders' Pennsylvania-law claims. The underlying coverage dispute — whether Great Lakes properly denied Raiders' insurance claim under New York law — was not resolved by the Supreme Court and would be addressed in the lower courts under New York law. Going forward, maritime parties nationwide can rely on choice-of-law clauses being enforced.
What this does not decide
The Court explicitly declined to resolve whether Wilburn Boat Co. v. Fireman's Fund Insurance Co. (1955) is in tension with modern maritime law or should be reconsidered — that question was unnecessary to resolve here. The ruling also does not decide whether Great Lakes properly denied Raiders' insurance claim; only which state's law governs that question.
Concurrences and dissents
Concurrence — Justice Thomas
Justice Thomas joined the majority opinion in full but wrote separately to argue that the Court's 1955 decision in Wilburn Boat was wrongly decided from the start. He contended that Wilburn Boat incorrectly found no established federal admiralty rule on warranty compliance, completely ignored the uniformity principle fundamental to admiralty law, and has generated decades of criticism and legal confusion. Thomas argued that the Court has been quietly limiting Wilburn Boat to disputes that are purely local in character, and he urged future litigants and courts to apply it only in truly local disputes — and no further.
How the Court got there
The legal reasoning, step by step
- Federal courts have constitutional authority over all admiralty and maritime cases under Article III, which requires a uniform body of maritime law operating consistently across the entire country. When no act of Congress applies, federal courts act as common-law courts, fashioning maritime rules from precedent, treatises, and scholarly sources — and they follow already-established maritime rules rather than reinventing them case by case.
- The threshold question was whether an established federal maritime rule already addressed the enforceability of choice-of-law clauses. The Court found that it did: multiple courts of appeals had consistently held such clauses presumptively enforceable, and the Supreme Court's own historical practice of enforcing them — dating back over a century — confirmed a well-established federal rule. No gap existed for state law to fill.
- The Court drew directly on its earlier decisions holding that forum-selection clauses (which specify where disputes must be litigated) are presumptively valid in maritime contracts. Choice-of-law clauses serve the same purposes — reducing legal uncertainty and cutting the cost of resolving disputes — and are if anything less controversial, since they don't force parties to travel to a distant location to litigate.
- The Court distinguished Wilburn Boat Co. v. Fireman's Fund Insurance Co. (1955), which Raiders argued required applying state law here. Wilburn Boat addressed a warranty-breach question in a marine insurance policy and contained no choice-of-law clause; it applied state law only because no established federal maritime rule covered that specific warranty issue. Here, a federal rule already governs choice-of-law clause enforceability, so there is no gap for Wilburn Boat's gap-filling rationale to reach.
- The Court examined the narrow recognized exceptions to the presumption of enforceability — (a) the chosen law conflicts with a controlling federal statute or established maritime policy, or (b) the parties had no reasonable basis for choosing that jurisdiction — and confirmed Raiders did not claim either exception applied. New York's commercial law was a perfectly reasonable choice that parties regularly make for well-developed, well-regarded legal rules.
- The Court rejected Raiders' proposed new exception: that a court can override a maritime choice-of-law clause when enforcing it would violate the public policy of the state with the greatest interest in the dispute. Such an exception would let all 50 states individually unravel maritime agreements, producing the very disuniformity and uncertainty that choice-of-law clauses exist to prevent — and it would just substitute one state's law for another's with no federal maritime interest served either way.

Reaffirms The Bremen v. Zapata Off-Shore Co. (407 U.S. 1)
The rule making forum-selection clauses presumptively valid in maritime contracts directly supports the same rule for choice-of-law clauses.

Confirms that maritime contract clauses reducing litigation uncertainty are presumptively enforceable, reinforcing today's holding.
Reaffirms Norfolk Southern R. Co. v. James N. Kirby, Pty Ltd. (543 U.S. 14)
Reaffirmed that federal maritime law requires national uniformity and controls non-local maritime contract disputes.
