If you commit a crime in Antarctica, your home country prosecutes you under its own criminal laws. The continent has no government, no police force, and no courts. Instead, the 58 nations that signed the Antarctic Treaty agreed that each country is responsible for the conduct of its own citizens on the ice. An American who assaults a coworker at a research station faces the same federal charges as if the assault happened in the United States. A Russian who stabs a colleague at a polar base gets sent home and charged under Russian law.
Why Nationality Decides It
The rule comes from Article VIII of the Antarctic Treaty. Designated treaty observers, exchanged scientific personnel, and their staff are “subject only to the jurisdiction of the Contracting Party of which they are nationals in respect of all acts or omissions occurring while they are in Antarctica.”1Secretariat of the Antarctic Treaty. The Antarctic Treaty – Full Text For everyone else, the treaty deliberately avoided the question, leaving jurisdiction “without prejudice to the respective positions of the Contracting Parties.” The drafters could not agree on who should have authority over non-designated personnel, tourists, or contractors, so they left it open.
In practice, the nationality principle has filled that gap. Each treaty nation prosecutes its own citizens, even those outside Article VIII’s specific categories, because the alternative (one country claiming territorial authority on a continent nobody officially owns) would collapse the treaty’s careful freeze on sovereignty.2Secretariat of the Antarctic Treaty.

What Happens Right After the Crime
There are no full-time police at any Antarctic station. For American bases, the U.S. Marshals Service is the official law enforcement entity, through an agreement with the National Science Foundation and the U.S. Attorney for Hawaii. NSF station managers at McMurdo and the South Pole receive training in crime investigation and evidence handling, and are sworn in as Special Deputy U.S. Marshals.3U.S. Marshals Service.

When something serious happens, the station manager’s job is to secure the scene, preserve evidence, and keep the suspect separated from the victim. There is no detention facility. In the 1996 case of an American cook who attacked a coworker with a hammer at McMurdo, the suspect was simply confined to a hut until investigators could arrive. A full investigation requires deploying FBI agents, usually from Hawaii, and Antarctic weather can ground flights for days. Suspect and victim may be stuck at the same small station in the meantime.4National Aeronautics and Space Administration. TIGER in Antarctica – Crime and Punishment
Getting the Suspect to Court
Once investigators finish on site, the suspect is flown back to the United States for trial. Prosecution falls to the U.S. Attorney for the District of Hawaii, which is the closest federal court district to the American Antarctic stations and already handles crimes at remote Pacific sites.4National Aeronautics and Space Administration. TIGER in Antarctica – Crime and Punishment Minor offenses that do not warrant a federal case are usually handled administratively: the person is fired and put on the next flight north.
Which U.S. Laws Apply
The statute that carries American criminal law to the bottom of the world is 18 U.S.C. ยง 7, which defines the “special maritime and territorial jurisdiction of the United States.” Paragraph 7, added by the Comprehensive Crime Control Act of 1984, extends that jurisdiction to “any place outside the jurisdiction of any nation with respect to an offense by or against a national of the United States.”5Office of the Law Revision Counsel. 18 USC 7 – Special Maritime and Territorial Jurisdiction of the United States Because no country has recognized sovereignty over Antarctica, the entire continent qualifies.
The full range of federal criminal law travels with every American on the ice. Assault, theft, sexual assault, drug offenses, murder. All carry the same penalties as they would in any federal district. There is no separate Antarctic criminal code and no leniency for the extreme conditions. Before paragraph 7 existed, a 1963 State Department legal memorandum noted that the government could find “no United States legislation by its terms specifically applicable to Antarctica.”6Office of the Historian. Foreign Relations of the United States, 1961-1963, Volume XXV, Document 474 The 1984 amendment closed that gap.
When the Perpetrator and Victim Are From Different Countries
The hardest situations are those where attacker and victim hold different nationalities. Article VIII paragraph 2 anticipates the problem without solving it, saying the parties involved “shall immediately consult together with a view to reaching a mutually acceptable solution.”1Secretariat of the Antarctic Treaty. The Antarctic Treaty – Full Text No binding arbitration exists, and no international court has standing jurisdiction over Antarctic crimes.
Typically the perpetrator’s home country takes the lead, because it has the clearest legal authority over its own citizen. But the victim’s country may also claim jurisdiction. U.S. law, for example, reaches offenses committed “by or against” an American national in places outside any nation’s control.5Office of the Law Revision Counsel. 18 USC 7 – Special Maritime and Territorial Jurisdiction of the United States If a foreign national attacked an American researcher, the United States could theoretically assert jurisdiction, though doing so against another treaty nation’s citizen would create significant diplomatic friction.
Cases That Show How It Actually Plays Out
Antarctic crime is rare, but not hypothetical. Small, isolated communities, months of winter darkness, no way to leave, and often alcohol on hand: tensions build.
In 1996 an American cook at McMurdo attacked a coworker with a hammer. The FBI deployed agents, and the cook was eventually taken into custody and returned to the United States. In 2018, at Russia’s Bellingshausen Station, researcher Sergey Savitsky stabbed a colleague in the dining hall after months of working together. The injured man was evacuated to Chile for medical care. Savitsky turned himself in to the station chief, was returned to Russia, and faced attempted murder charges there.
Not every case gets resolved. Australian astrophysicist Rodney Marks died at the Amundsen-Scott South Pole Station in 2000. An autopsy in New Zealand found methanol poisoning, but New Zealand police could not determine whether the death was accidental, a suicide, or a homicide. The remoteness and the delay in transporting the body hampered the investigation. The case remains unsolved.
Sexual harassment and assault have been a persistent problem at American stations. A 2022 National Science Foundation report documented systemic issues at McMurdo, including incidents that were misclassified, inadequately investigated, or responded to by removing the victim rather than the accused. The NSF has since required contractors to report incidents immediately and has established a confidential victim advocacy office and a 24-hour helpline. The systems exist on paper. The isolation makes enforcement genuinely difficult.
Environmental Offenses Are a Separate Track
Not every Antarctic offense is a violent crime. The Protocol on Environmental Protection to the Antarctic Treaty, adopted in 1991 and in force since 1998, designates the continent as “a natural reserve, devoted to peace and science” and bans mineral extraction except for scientific research.7U.S. Department of State. Antarctic Treaty – Environmental Protocol – National Contacts It also governs waste disposal in detail: radioactive materials, batteries, fuel, plastics, and heavy metals must be removed from the continent, and dumping into the surrounding seas is prohibited. PCBs cannot be brought in at all.8Secretariat of the Antarctic Treaty. Waste Disposal and Management
For Americans, the Antarctic Conservation Act translates these obligations into enforceable domestic law. It requires permits from the National Science Foundation for collecting native wildlife, entering specially protected areas, or introducing non-native species.9National Science Foundation. Antarctic Conservation Act Permit Application Form (NSF Form 1078) Violations can carry civil penalties of up to $5,000 per incident, with higher penalties for knowing violations.
Private expeditions carry their own paperwork. Any American organizing or joining a non-governmental trip must file a DS-4131 Advance Notification Form with the State Department’s Office of Ocean and Polar Affairs at least three months before departure, under Article VII of the treaty. Tour operators handle this for their clients, but independent travelers and private researchers file on their own. Skipping the notification can strip you of the legal protections and logistical support the treaty system provides, in a place where getting either on short notice is not an option.
