Admiralty Courts in the United States are federal district courts that hear sea cases. If you sue the ship itself, only a federal judge will hear it. State courts still hear many sea injury and contract claims when you sue a person or a company because a law from 1789 left that choice open for the hurt side. The court you pick decides who judges you, whether a jury sits and how fast you get paid. Here is how the two systems share the work and how to pick the right one.
The ship that made Boston furious
In June 1768, customs officers in Boston seized a small sailing ship named Liberty. It belonged to John Hancock, a rich merchant. The officers said he had skipped the tax on a load of wine. They did not take the case to a regular court with a jury of local men. They took it to a vice-admiralty court where one judge picked by the Crown decided alone. A crowd attacked the customs men and they ran for safety. The Crown kept the ship. The case against Hancock himself was dropped in 1769.
Colonists took it as proof that the king could grab a ship and never face twelve local jurors. That fight is why the split between federal and state Admiralty Courts still matters today.
What happened in the vice-admiralty court?
The Crown created vice-admiralty courts in the colonies to deal with shipping and customs cases. A Crown-appointed judge handled each case without a jury. The Sugar Act of 1764 brought more customs cases into these courts and the Stamp Act of 1765 added stamp-related cases. One court was in Halifax, Nova Scotia, far from many colonial ports. Ship owners sometimes had to travel long distances just to defend their property.
Colonists saw this system as unfair. The Declaration of Independence even accused the king of denying people the right to a jury trial in many cases. After the American Revolution, the new country kept admiralty law and placed it under federal courts while still allowing some common law remedies. This decision shaped how admiralty law works in the United States today.
Where federal power over Admiralty Courts comes from
Article III of the Constitution gives federal courts power over cases of admiralty and maritime law. The Judiciary Act of 1789 put that power in the federal district courts. Today the rule sits in Title 28, section 1333 of the United States Code. It says federal district courts hold the power to hear admiralty cases and states don’t share it. Then it adds a short phrase that saves to suitors all other remedies they already hold. A suitor is just a person who sues.
That law is why Admiralty Courts sit inside the federal system and not in the states.
The saving to suitors clause explained
This phrase is the heart of the fight. It lets an injured person or a creditor use a common law remedy such as a lawsuit against the owner in state court. So a sea accident has more than one way in. One leads into federal Admiralty Courts where a judge decides alone. Another leads to a state court where the plaintiff asks for a jury. The last goes to a federal court on another ground such as the two sides living in different states and jury sit there too.
A hurt sailor with a Jones Act claim which covers an employer’s carelessness at sea, gets the same choice between a federal and a state courtroom.
What only federal Admiralty Courts decide
A claim against the ship itself is called in rem which means against the thing. The saving clause does not reach it. Only a federal court hears it. A federal marshal arrests the ship and the ship sits at the dock until someone pays or posts a bond. The ship must be inside that court’s district when the case starts.
For a lender, a repair yard or a crew owed wages this is the fastest way to get paid because a ship earns nothing while it sits in port.
Why flags of convenience matter in Admiralty Courts
Ownership papers make a sea claim harder than it sounds. A ship flies the flag of Panama belongs to a shell company in another country and runs under a manager in a third. Finding the real owner to sue takes months. The ship is easier to find if it enters a United States port, a federal court has the power to arrest it.

The test federal judges use to take a case
Before a federal judge takes a sea injury case the judge asks two simple questions. Did the harm happen on water open to ships or did a ship on that water cause it? Does the event threaten shipping and is the activity tied to normal sea work? The Supreme Court set this test in Grubert v. Great Lakes Dredge and Dock company in 1995. The case came from the 1992 Chicago flood when work on the river bottom broke a tunnel wall and water filled basement downtown.
Two pleasure boats that collide on a river pass the test. A fight at a lakeside restaurant fails it. These two questions keep Admiralty Courts from taking every dispute that happens near water.
How The Genesee Chief Expanded Federal Admiralty Jurisdiction
Early American courts took cases only from waters where the tide moves. That rule left Great Lakes out. In 1852 the Supreme Court dropped it in The Genesee Chief v. Fitzhugh a collision case from Lake Ontario. The Court said federal courts reach any water open to ships that is used for trade. Lakes and rivers with no ocean tide came in.
That ruling is why a boat collision on Lake Erie belongs in federal court.
What state courts must follow
A state judge who hears a sea claim must follow federal maritime law. States don’t write their own rules for sea injuries.
In Southern Pacific Company v. Jensen in 1917 the Supreme Court held that New York could not use its workers pay law for a man killed while unloading a ship. The Court wanted one set of rules for ships that sail from port to port. Later cases give states more room but the core rule stands. No state rule is allowed to clash with maritime law.
How Lewis v. Lewis and Clark Marine shifted power to injured workers
Shipowners have a tool in federal court that caps what they owe at the value of the ship after an accident. The owner files in federal court and asks the judge to freeze every other suit. In 2001 the Supreme Court decided Lewis v. Lewis and Clark Marine. An injured worker had sued in state court, and the owner tried to lock the case in federal court. The Court said the saving clause protected the worker’s choice when only one person claims against the owner and that person gives the federal court the final say on the cap.
The ruling shows that Admiralty Courts don’t always keep a case they start.
How to determine territorial jurisdiction?
The first step is the same for Admiralty Courts and every other court: find the link between the case and the place. Ask four simple Questions. Where did the harm happen? Where does the defendant live or do business? Where is the ship now? What do the contract papers say?
For a claim against a ship, the ship must be inside the court’s district when you file so where it sits picks the court. For a claim against a person or company the court needs a link to that defendant such as an office in the state or harm done there.
On the water, the lines run like this. Most coastal states own the first three nautical miles from shore. Texas and the Gulf coast of Florida own nine. The United States claims 12 nautical miles as it territorial sea.
Admiralty law applies in state water and federal water alike, so the line mostly decides which state’s courts sit closest to the harm.
A lesson from my own courtroom
I practice family law before the Courts. I don’t argue cases in Admiralty Courts still, the same lesson holds in my work. When a case lands in court with no power over it the court sends it back and the client loses weeks and fees. Territorial jurisdiction decides everything that follows, so I check it before I write one line of a plaint.
Does a federal judge have authority over the president?
Yes, but within limits. Federal courts have checked the executive branch since Marbury v. Madison in 1803. In United States v. Nixon in 1974, the Supreme Court ordered the president to hand over the Watergate tapes. In Clinton v. Jones in 1997 it ruled that a sitting president must answer a federal civil lawsuit over acts from before he took office.
Trump v. United States in 2024 drew a different line for crimes. A president has absolute immunity means full protection from prosecution for acts inside his core powers. He has presumed immunity for other official acts and none for private acts.
Judges also have no army. United States marshals sit inside the executive branch, so courts need that branch to carry out their orders.
Admiralty Courts show how far that reach goes. The Suits in Admiralty Act lets a person sue the federal government over a government ship or cargo and the Public Vessels Act covers claims over navy and other public ships. A federal judge hears those claims and rules against the government when the facts call for it.
Deadlines and ticket fine print that decide your case
Time limits kill more claims in Admiralty Court than weak proof does. Most sea injury claims face a three-year limit under federal law. Cargo claims under the Carriage of Goods by Sea Act face a one-year limit from delivery.
Cruise tickets come with fine print. In Carnival Cruise Lines v. Shute in 1991, the Supreme Court upheld a ticket clause that forced a Washington couple to sue in Florida. Read the ticket, the bill of lading and the contracts before you choose a court.
How to choose between a federal and a state court
Pick federal court when you sue the ship itself, when your contract names a federal court or when you want one judge who sees sea cases every week. Pick state court when you want a jury, when the harm and the witnesses sit close to that courthouse or when the claims run against a person or company.
Write down four facts before you call a lawyer: where it happened, who owns the ship, what the contract says and when the harm took place. Maritime lawyers read those four facts first.
What to do next
Admiralty Courts split power with the states on purpose. The split gives injured people a choice and gives ships one set of rules. Use that choice with care. Check the facts, the deadline and the ticket then pick the door that match your claim.
