Bisso v. Inland Waterways Corp.
The Supreme Court ruled that a towboat operator cannot use a contract to wipe out all liability for its own negligence in towing another vessel, striking down two clauses that tried to shift the blame onto the barge being towed.
The decision settles a decades-long split among lower courts and establishes a firm admiralty rule: towing companies cannot bargain their way out of responsibility for careless towing, protecting shippers who often have little leverage to negotiate otherwise.
“Because of this judicial history and cogent reasons in support of a rule outlawing such contracts we now, despite past uncertainty and difference among the circuits, accept this as the controlling rule.”
The Court announces its adoption of a firm rule against towage negligence-exemption contracts.
How it got here: The district court, sitting in admiralty, upheld the exculpatory clauses and ruled for the towboat owner; the Court of Appeals affirmed, and the Supreme Court agreed to hear the case.
The Case in Depth
What happened
An oil barge, the Bisso, was being towed up the Mississippi River by a steam towboat, the Cairo, when it collided with a bridge pier and sank because of negligent towing. The towing contract contained two clauses meant to shield the towboat's owner from liability: one placing the towing at the barge's "sole risk," and another declaring the towboat's crew to be legally the barge's own employees.
The question before the Court
Could a towboat company use a contract clause to escape all legal responsibility for its own crew's negligent towing?
Why it matters
Businesses that ship goods or vessels by barge can no longer be forced to accept contracts that let towing companies off the hook for careless accidents. The ruling protects shippers—who often must use whichever towing company operates in a given port—from being pressured into one-sided contracts, and it gives towing companies a continuing financial incentive to operate carefully.
What changes now
The judgment against the barge owner is reversed, meaning the towboat's negligence claim proceeds on the understanding that the exculpatory clauses are unenforceable and the towboat owner remains liable for the damage caused by its crew's negligence. The decision fixes a longstanding split among the federal circuits going forward, establishing a uniform admiralty rule that applies to towage contracts generally, though Congress remains free to legislate differently.
What this does not decide
The Court's ruling is limited to contracts that try to release a towboat from all liability for its own negligent towing; it does not disturb the separate rule from Sun Oil Co. v. Dalzell Towing Co. allowing exemptions specifically for a pilot's negligence, given pilots' distinct regulated role.

How the Justices voted
Majority (1). Justice Black (author).
Separate writings (1). Justice Douglas (author of a concurrence).
Dissent (1). Justice Frankfurter (author).
Concurrence — Justice Douglas
Justice Douglas agreed the established rule against exculpatory towage clauses should stand, but stressed that the Court lacks enough information about the tugboat industry's economics and competitive structure to decide whether the rule should be changed. He noted the same policy reasons barring common carriers from disclaiming negligence apply equally to contract carriers like the towboat here, and said any change to the rule should come from Congress after a fuller economic study.

Dissent — Justice Frankfurter
Justice Frankfurter argued that neither The Steamer Syracuse nor The Wash Gray ever actually decided the validity of a full negligence exemption—both were narrow rulings about how to construe ambiguous contract language. He contended the weight of lower-court authority, especially in the most active admiralty circuits, upheld such clauses, and that Sun Oil's reasoning about arm's-length bargaining and absence of monopoly power applied equally here. Finding no proof of unequal bargaining power in this record, he would have enforced the contract and affirmed. Read the full dissent →
How the Court got there
The legal reasoning, step by step
- The Court traced its own 1871 decision in The Steamer Syracuse and its 1928 decision in The Wash Gray, reading both as reflecting a public-policy rule—not merely a quirk of contract wording—that a tower must answer for its own negligence despite any contract saying otherwise.
- The Court applied a general principle used across many fields of law—bailors and bailees, employers and employees, public service companies and customers—that release-from-negligence contracts are unenforceable when one side needs the service and the other holds the power to dictate terms.
- The Court explained the rule serves two purposes: discouraging carelessness by making negligent parties pay for the harm they cause, and protecting people who need towing services from being pressured into one-sided contracts by towing companies that may have monopoly-like power in a given port.
- The Court distinguished its own earlier decision in Sun Oil Co. v. Dalzell Towing Co., which upheld a contract shielding a tug from liability only for a pilot's negligence. It reasoned that pilots occupy a specially regulated, independent role unlike ordinary towing crews, so permitting a pilotage exemption does not conflict with barring a full towing exemption.
- Applying this rule to the two contested clauses, the Court held that placing towing at the barge's 'sole risk' improperly shifted liability to the barge, and that labeling the towboat's crew as the barge's own employees was a legal fiction that could not change who actually controlled and paid the crew, so neither clause could shield the towboat owner from its own negligence.
Doctrinal impact
Cases affected by this decision
Reaffirms The Steamer Syracuse (12 Wall. 167)
The Court treats this 1871 decision as establishing that tow contracts cannot excuse a towboat's own negligence.
Reaffirms The Wash Gray (277 U.S. 66)
The Court relies on this 1928 ruling as confirming the same rule against negligence-exemption towage contracts.
Distinguishes Sun Oil Co. v. Dalzell Towing Co. (287 U.S. 291)
The Court says this earlier ruling upholding a pilot-negligence exemption does not conflict with barring full towing exemptions.
