Flying Laws: Understanding Your Rights And Restrictions

Flying can be stressful, and sometimes situations escalate into criminal behaviour. But what laws apply when a crime is committed in the air?

When an aircraft is on the ground, the laws of that country apply. However, when a plane is in the air, the laws are more complicated. Generally, the country where the aircraft is registered has jurisdiction over offences committed on board. Multiple countries can apply jurisdiction at the same time, and the specific nature of an offence can dictate whether local jurisdiction applies. For example, if it concerns national security or affects a country's citizens.

The Tokyo Convention states that the laws of the country of registration of the aircraft apply to acts committed on board. This was extended by the Montreal Protocol in 2020, which gave automatic jurisdiction over criminal offences to the flight's destination country as well as the aircraft's country of registration.

So, the next time you're on a flight, remember that it's not just the flight path the pilot is in charge of – they're also responsible for your safety and can order passengers to be restrained.

Local laws apply when the plane is on the ground

When an aircraft is on the ground, the laws of the country it is in apply. This is the case for flights that have yet to take off and those that have landed at their destinations. Local laws will apply regardless of the airplane's country of residence, passenger nationality, or crew's nationality.

For example, in 2013, a Pakistan International Airlines pilot was arrested and charged when he was found to be over the legal alcohol limit for operating a flight from Leeds Bradford Airport in the United Kingdom. Although this would not have been a violation of the law in Pakistan, which has a 12-hour "bottle to throttle" rule, the pilot was charged under UK law. A similar case occurred in 2018 when a Singapore Airlines pilot was arrested in Melbourne for attempting to operate a flight while over the legal alcohol limit.

Before boarding, airline employees monitor passengers for signs of intoxication or aggression that could impact the safety or operation of the flight. If a problem arises, the airline will attempt to calm the passenger, and if necessary, work with airport police to have them arrested.

Laws of the country of aircraft registration apply in the air

When it comes to the laws that apply when flying, the situation can be complex and depends on several factors, including the nature of the offence, the location of the aircraft, and the nationalities of those involved. However, a general rule is that the laws of the country of aircraft registration apply to offences committed onboard. This is known as the "law of the flag" and is based on the concept of quasi-territorial jurisdiction, where a country's laws extend to its ships and aircraft.

The "law of the flag" principle is applied in international aviation law, particularly in the Tokyo Convention. According to this convention, the country where the aircraft is registered has jurisdiction over offences committed onboard. This means that the laws of that country will generally govern any incidents or crimes that occur during the flight. This convention also allows for multiple countries to have jurisdiction simultaneously and gives the aircraft commander the authority to maintain law and order onboard, including the right to disembark any offender in any contracting state where the aircraft lands.

However, it is important to note that the "law of the flag" is not the only factor at play. The laws of the country whose airspace the aircraft is traversing may also apply under certain conditions outlined in the Tokyo Convention. These conditions include when the act committed affects the overflown country, involves a national of that country, or concerns the national security or aviation regulations of that country.

Additionally, the Montreal Protocol of 2020 expanded the jurisdiction further. It grants automatic jurisdiction over criminal offences to both the flight's destination country and the aircraft's country of registration. This protocol aims to address the complexities of global aviation and ensure that offenders cannot exploit legal loopholes.

Airspace country laws may apply to in-flight offences

When an aircraft is on the ground, the laws of the country it is in apply. This takes precedence over the laws of the country of residence, passengers' nationality, or crew's nationality. However, once an aircraft is in the air, the laws that apply become more complex and depend on several factors.

Generally, the laws from the country of aircraft registration govern offences committed onboard. However, under specific conditions, the laws of the country whose airspace the aircraft is flying through may also apply to in-flight offences. These conditions are outlined in the Tokyo Convention and include the following:

• If the offence has an effect on the territory of the airspace country.
• If the offence has been committed by or against a national of the airspace country.
• If the offence is against the national security of the airspace country.
• If the offence consists of a breach of any rules and regulations relating to the flight and manoeuvre of aircraft in force in the airspace country.
• If the exercise of jurisdiction is necessary to ensure the observance of any obligation of the airspace country under an international agreement.

For example, a United States passenger aged 18 travelling on a Qantas aircraft in US airspace can legally drink alcohol, even though US law stipulates a minimum drinking age of 21. However, if a passenger is found to be in possession of illegal drugs on a Singapore Airlines flight from Singapore to Frankfurt, they would be prosecuted under German law, not Singapore's.

The Montreal Protocol, an expansion of the rules, gives jurisdiction to the arriving country and the home country of the operator in some cases, providing more flexibility in dealing with offences that fall into a grey area of jurisdiction.

Criminal jurisdiction and crimes against aircraft

The Tokyo Convention established that the country where the aircraft is registered has jurisdiction over offenses committed onboard. However, the Montreal Protocol expanded this, giving jurisdiction to the arriving country and the home country of the operator as well. This was done to provide more flexibility to authorities and encourage cooperation between states in prosecuting offenders.

In the case of international flights, determining jurisdiction can be challenging, and there may be conflicts between the laws of different countries. To address this, the 1963 Tokyo Convention on Offences and Certain Other Acts Committed on Board Aircraft was established, requiring contracting states to extend their criminal laws and jurisdiction to aircraft registered in their country when they are outside national territory. This convention also empowers the aircraft commander to ensure law and order onboard and disembark offenders in any contracting state where the aircraft lands.

Crimes against aircraft, such as piracy, are specifically addressed in the 1958 Geneva Convention on the High Seas, which defines piracy as:

> any illegal acts of violence, detention or any act of depredation, committed for private ends by the crew or the passengers of a private ship or a private aircraft, and directed: (a) on the high seas, against another ship or aircraft, or against persons or property on board such ship or aircraft; (b) against a ship, aircraft, persons or property in a place outside the jurisdiction of any State.

The convention further states that:

> On the high seas, or in any other place outside the jurisdiction of any State, every State may seize a pirate ship or aircraft, or a ship taken by piracy and under the control of pirates, and arrest the persons and seize the property on board.

Piracy, in this context, deliberately excludes acts committed for political motives or confined within an aircraft, such as mutiny or hijacking.

In the United States, aviation offenses are typically prosecuted in federal courts, with strict sentencing guidelines and severe penalties. Special aircraft jurisdiction applies to crimes committed on US planes, planes operated by US commercial airlines, US military aircraft, and certain other scenarios, such as crimes committed on a flight with a US departure or destination. Federal law separates aviation crimes into two categories: piracy within special aircraft jurisdiction and piracy outside of it. Other types of aviation crimes under federal law include interference with crew members or attendants, interference with airport security screeners, possessing or placing weapons or explosives on a plane, and conduct that would constitute certain enumerated crimes if committed within US maritime or territorial jurisdiction.

International agreements and conventions

The Montreal Protocol, an extension of the Tokyo Convention, grants automatic jurisdiction over criminal offences to the flight's destination country and the aircraft's country of registration. This protocol aims to address a loophole that allowed offenders to walk free when their flight landed in a different country than the one where the aircraft was registered. Additionally, the Chicago Convention, among ICAO members, exempts aircraft from seizure or detention on patent claims in other contracting states without the need for security deposits.

The 1929 Warsaw Convention on International Carriage by Air, as modified by the 1961 Guadalajara Convention and the 1971 Guatemala City Protocol, restricts legal actions arising from "international" carriage by air to the courts of specific contracting states. Furthermore, the 1933 Rome Convention on Precautionary Arrest of Aircraft exempts government service or commercially used aircraft from precautionary attachment, while the 1952 Rome Convention on Surface Damage limits legal actions to the courts of the contracting state where the damage occurred.

The 1958 Geneva Convention on the High Seas addresses crimes against aircraft, defining piracy as illegal acts of violence, detention, or depredation committed by the crew or passengers of a private ship or aircraft for private ends. This convention also grants states the right to seize pirate ships or aircraft and decide on penalties. However, it excludes acts committed for political motives or confined within an aircraft, such as mutiny or hijacking.
