Federal Maritime Commission v. South Carolina State Ports Authority
The Supreme Court ruled that states cannot be forced to defend themselves before the Federal Maritime Commission when a private company files a complaint against a state-run port, because states have the same immunity from such agency hearings that they have from private lawsuits in court.
The decision extends state sovereign immunity beyond courtrooms to court-like federal agency proceedings, meaning private parties cannot use administrative complaints as a workaround to sue states that haven't consented to be sued.
“Given both this interest in protecting States' dignity and the strong similarities between FMC proceedings and civil litigation, we hold that state sovereign immunity bars the FMC from adjudicating complaints filed by a private party against a nonconsenting State.”
The core holding extending state sovereign immunity to agency adjudications.
How it got here: An administrative law judge dismissed the complaint on immunity grounds, the full Commission reversed, and the Fourth Circuit then reversed the Commission and sided with the port.
The Case in Depth
What happened
A cruise company, South Carolina Maritime Services, wanted to berth a gambling cruise ship at the Port of Charleston, but the South Carolina State Ports Authority repeatedly refused, citing a policy against gambling vessels while allowing similar Carnival Cruise Lines ships to dock. The company filed a complaint with the Federal Maritime Commission, arguing the port's refusal violated the Shipping Act by unfairly favoring Carnival and unreasonably refusing to deal with it.
The question before the Court
Can a federal agency hold a trial-like hearing on a private company's complaint that a state-run port violated federal shipping law, without the state's consent?
The Court's answer
No — the Court ruled that state sovereign immunity does bar the Federal Maritime Commission from adjudicating a private party's complaint against a nonconsenting state-run port. Even though the Commission is an executive-branch agency rather than a court, the Court found its hearing process so similar to a civil lawsuit — with pleadings, discovery, an impartial adjudicator, and binding findings — that forcing a state to participate offends the same dignity interests that sovereign immunity protects in court.
The Court stressed this immunity applies regardless of what remedy is sought, whether money damages or a cease-and-desist order, because the doctrine's core purpose is respecting a state's status as a sovereign, not just protecting its treasury. The Commission remains free to investigate Shipping Act violations on its own and to sue states directly in federal court, but it cannot let a private party's complaint trigger its own adjudicative process against an unwilling state.

Why it matters
Private businesses that believe a state-run port, university, or other state agency violated federal law can no longer bring that dispute directly to a federal agency for a trial-like ruling if the state objects. They must instead rely on the federal government itself to investigate and pursue enforcement, which can be slower and less directly responsive to an individual complainant's grievance.
What changes now
The Federal Maritime Commission may no longer adjudicate private complaints against nonconsenting state-run ports through its trial-like hearing process, but it retains the power to investigate Shipping Act violations on its own initiative and to sue a state in federal court to enforce the law. Maritime Services' complaint against the SCSPA remains dismissed. Private parties with similar grievances against state entities must now rely on the FMC or the Attorney General to pursue enforcement rather than filing their own agency complaints.
What this does not decide
The Court did not decide whether sovereign immunity would apply if a state could get full independent judicial review of an agency order without first appearing before the agency, and it left the Commission free to investigate and sue states directly in federal court to enforce the Shipping Act.
Concurrences and dissents
Dissent — Justice Stevens
Justice Stevens joined Breyer's dissent in full but wrote separately to stress that the majority's two foundations—Alden v. Maine and the idea that sovereign immunity protects state 'dignity'—are especially weak. He traced the Eleventh Amendment's legislative history to argue Congress rejected language that would have protected states from process itself, choosing instead language about subject-matter jurisdiction, showing dignity was never the real concern.
Dissent — Justice Breyer
“Where does the Constitution contain the principle of law that the Court enunciates? I cannot find the answer to this question in any text, in any tradition, or in any relevant purpose.”Breyer's central objection that the majority's rule has no textual or historical grounding.
Justice Breyer argued the Constitution's text, history, and purpose give no support for barring an executive agency from adjudicating private complaints against states, since agencies exercise executive, not judicial, power and the Eleventh and Tenth Amendments don't address this. He contended the majority's analogy between agency proceedings and lawsuits is flawed, that any 'coercion' on states is no different from other lawful political pressures, and that the ruling will force wasteful growth of federal bureaucracy while weakening enforcement of worker-protection and other laws.
How the Court got there
The legal reasoning, step by step
- The Court applied the Hans presumption, a longstanding rule that the Constitution should not be read to allow lawsuits against states that would have been unfamiliar or unthinkable when the Constitution was adopted, to decide whether the Framers would have expected states to be immune from this kind of proceeding.
- Because states were not subjected to private complaints before administrative agencies at the founding or for well over a century afterward, the Court found no historical basis for concluding that states gave up immunity from this type of proceeding when they joined the Union.
- The Court then closely compared the Commission's procedures to a real lawsuit, finding that its rules on filing complaints, answers, discovery, depositions, and rulings by an administrative law judge closely track the Federal Rules of Civil Procedure, making the agency proceeding functionally indistinguishable from civil litigation despite happening inside the executive branch.
- The Court reasoned that the core purpose of state sovereign immunity is protecting a state's dignity from being hauled before an adversarial tribunal at a private party's demand, not merely protecting the state treasury, so that dignity interest is equally offended whether the tribunal is a court or an agency.
- Relying on its earlier decision in Seminole Tribe, the Court reasoned it would be inconsistent to bar Congress from forcing states into private lawsuits in federal court under its Article I powers while allowing Congress to achieve the same result by routing the same kind of dispute through a court-like agency instead.
- The Court concluded that because FMC adjudications are the practical equivalent of private lawsuits against a state, sovereign immunity bars the Commission from adjudicating a private party's complaint against a nonconsenting state, regardless of what remedy the private party seeks.
