No, we are not under maritime law in any general sense. Maritime law is a narrow body of rules that applies to incidents on navigable waters with a real connection to shipping, vessel operations, or seafaring commerce. If you’re on land, driving, working, renting, paying taxes, or standing in a courtroom, the law governing you is the ordinary mix of the U.S. Constitution, federal statutes, and state codes — not admiralty.
What Maritime Law Actually Covers
Federal authority over maritime cases comes from Article III, Section 2 of the Constitution, which extends judicial power to “all Cases of admiralty and maritime Jurisdiction.”1U.S. Congress. Federal Admiralty and Maritime Jurisdiction Generally Congress carried that power into 28 U.S.C. § 1333, which gives federal district courts original jurisdiction over “any civil case of admiralty or maritime jurisdiction.”2Office of the Law Revision Counsel. 28 USC 1333 – Admiralty, Maritime and Prize Cases
The disputes that fall inside that jurisdiction are specific: shipping contracts, collisions between vessels, cargo damage, marine insurance, salvage rights, and injuries to crew members. The point of the system is practical. A cargo ship moving from Houston to Hamburg needs one consistent set of liability rules, not a different regime at every port. Maritime law creates that uniformity for a global industry. It was never designed to govern the life of someone who lives inland and never sets foot on a vessel.
The Two Tests a Court Uses
A court doesn’t apply maritime law just because water is somewhere in the picture. Two tests have to be met, and failing either one keeps a case in ordinary land-based law.
The first is the locality test: did the incident happen on navigable waters? Navigable waters are oceans, major rivers, the Great Lakes, and other waterways used or capable of being used for interstate or international commerce. A crash on a bridge over a river doesn’t qualify. A collision between two barges on that river does.
The second is the maritime nexus test. Even when something happens on navigable water, the activity has to bear a significant relationship to traditional maritime commerce. In Sisson v. Ruby (1990), the Supreme Court held that courts should assess “the general features of the type of incident involved to determine whether such an incident is likely to disrupt commercial activity.”3Cornell Law School. Sisson v Ruby, 497 US 358 (1990) In Jerome B. Grubart, Inc. v. Great Lakes Dredge & Dock Co. (1995), the Court added that both the potential hazard to maritime commerce and a substantial relationship to traditional maritime work must be established.4Cornell Law School. Jerome B. Grubart Inc v Great Lakes Dredge and Dock Co, 513 US 527 (1995)
These tests exist to keep admiralty from creeping past its intended scope. A contract to build a ship is generally treated as a land-based agreement, even though the finished ship will sail. An injury on a dock or pier often fails the locality test because the structure is treated as an extension of land. Whatever you’re doing on shore, none of it satisfies either test.
What Governs Your Daily Life Instead
Unless you work on a vessel, ship cargo internationally, or are involved in an incident on navigable waters, the framework governing your life is the ordinary combination of federal and state law. The Tenth Amendment reserves to the states all powers not granted to the federal government,5Cornell Law School. US Constitution Tenth Amendment which is why states handle criminal law, traffic enforcement, property, family law, and most contracts. Federal law covers interstate commerce, immigration, bankruptcy, and taxes. None of it operates on admiralty principles.
When you get a traffic ticket, sign a lease, file for divorce, or face criminal charges, you’re in that land-based system. Courts follow standard civil or criminal procedure, which typically includes the right to a jury trial. There is no hidden layer of maritime authority running underneath any of it.
Where Maritime Law Can Actually Reach You
There are a few real situations where maritime law reaches people who don’t think of themselves as sailors. These are the overlaps worth knowing.
Harbor and Dock Workers
The Longshore and Harbor Workers’ Compensation Act covers employees in maritime occupations such as longshore workers, ship repairers, and shipbuilders who are injured on navigable waters or in adjoining areas like piers, docks, and terminals.6U.S. Department of Labor. Longshore and Harbor Workers Compensation Act Frequently Asked Questions The Act specifically excludes seamen, government employees, and workers doing purely clerical or office work. If you load cargo at a port, this federal system applies rather than state workers’ compensation.
Injured Seamen
Crew members aboard vessels have their own protections. Under the Jones Act, 46 U.S.C. § 30104, a seaman injured during employment can sue the employer for negligence and has the right to a jury trial.7Office of the Law Revision Counsel. 46 USC 30104 – Personal Injury to or Death of Seamen The separate doctrine of maintenance and cure requires a vessel owner to provide an injured seaman with food, lodging, and medical treatment until maximum medical improvement, regardless of fault. Seamen are generally excluded from ordinary workers’ compensation, so maritime law fills the gap.
Cruise Passengers
If you’ve booked a cruise, you’ve agreed to a maritime contract, usually buried in the ticket’s fine print. These contracts routinely include forum selection clauses that require any lawsuit to be filed in a specific court, often in Miami, and choice-of-law provisions specifying which jurisdiction’s law controls. Federal courts generally enforce these clauses, and the Supreme Court has endorsed a strong presumption of enforceability for such provisions in maritime contracts. The practical effect: if you’re injured on a cruise, you may not be able to sue in your home state, and the applicable law may limit your recovery compared to what state law would allow.
Filing Deadlines
Maritime claims run on their own clock. A personal injury or wrongful death claim arising from a maritime incident must be filed within three years.8Office of the Law Revision Counsel. 46 USC 30106 – Time Limit on Bringing Maritime Action for Personal Injury or Death Missing the three-year window forfeits the claim, and some state personal injury statutes allow longer windows, which catches people off guard.
The Gold Fringe Flag and Related Claims
The most common version of the “we’re under maritime law” claim points to the gold fringe on flags in courtrooms. The theory is that the fringe signals admiralty jurisdiction and makes the court’s rulings over ordinary citizens illegitimate. The argument comes from the sovereign citizen movement, and federal courts have rejected it for decades.
In McCann v. Greenway (1997), a federal court cataloged multiple prior decisions dismissing the flag fringe theory. Courts in Texas, Virginia, and Pennsylvania all independently rejected the argument, with one court calling it “a really unintelligible assertion” and others labeling it “totally frivolous.”9Justia Law. McCann v Greenway, 952 F Supp 647 (WD Mo 1997) No court in U.S. history has ever ruled that flag decorations change a court’s jurisdiction. Jurisdiction comes from the Constitution and implementing statutes.
Related claims from the same movement include the idea that writing your name in capital letters on a legal document creates a separate legal entity subject to admiralty, or that the Uniform Commercial Code secretly governs all human interactions as maritime commerce. None of these theories have ever succeeded in any court. They share a structure: take a real but narrow legal concept, strip it from its context, and claim it applies everywhere. Maritime law is real. It governs ships and shipping.
What Happens If You Argue This in Court
Raising these theories doesn’t just lose. It triggers penalties.
Under Rule 11 of the Federal Rules of Civil Procedure, anyone who files a pleading based on legal contentions that aren’t “warranted by existing law or by a nonfrivolous argument” faces sanctions.10Cornell Law School. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers; Representations to the Court; Sanctions Those sanctions can include orders to pay the opposing party’s attorney fees, fines payable to the court, mandatory legal education, and referral to disciplinary authorities. Courts start with the least severe sanction that will deter the behavior, but repeat filers see that threshold escalate.
The IRS has been more explicit. Its official list of frivolous tax positions, Notice 2010-33, identifies Position 39: the argument that “Federal courts may not enforce the internal revenue laws because their jurisdiction is limited to admiralty or maritime cases or issues.”11IRS. IRS Notice 2010-33 – Frivolous Positions Filing a tax return or submission based on that position triggers a flat $5,000 civil penalty under 26 U.S.C. § 6702.12Office of the Law Revision Counsel. 26 USC 6702 – Frivolous Tax Submissions The penalty applies per submission, so multiple filings multiply the cost.
Beyond formal sanctions, judges can hold litigants in contempt for repeatedly disrupting proceedings with arguments the court has already rejected. Contempt carries the possibility of fines and jail time. Attorneys who present these theories risk professional discipline, including loss of their license. The legal system treats sovereign citizen maritime arguments not as creative theories deserving debate, but as a waste of judicial resources that has been thoroughly and repeatedly rejected.
