  • Mid-flight, a passenger turns violent and threatens the cabin crew. The captain has him restrained until landing.
  • Offences on board, and what the captain may do about them, are the Tokyo Convention. The State where the aircraft is registered has jurisdiction.
  • An armed man forces his way into the cockpit and orders the crew to fly to another country.
  • Seizing an aircraft by force is hijacking: the Hague Convention. Countries must punish it severely and extradite the offender.
  • Before departure, someone hides a device in the hold of an airliner, meant to destroy it in flight.
  • Placing a device on board that is likely to destroy or damage an aircraft is sabotage: Montreal 1971.
  • A passenger is injured on an international flight and claims compensation from the airline.
  • Claims by passengers (and for baggage or cargo) against the airline: the Warsaw Convention, or Montreal 1999 which aims to replace it.
  • A foreign aircraft crashes on landing approach and damages houses and cars on the ground.
  • Damage to people or property on the ground, caused by a foreign aircraft: the Rome Convention. The operator is liable, up to a limit based on the aircraft's weight.
  • Attackers use a cyber attack to break into air navigation systems.
  • Beijing 2010 brought the unlawful-acts treaties up to date, covering cyber attacks on navigation and safety systems, and biological and chemical threats.

  • Rights of lenders in aircraft and engines (mobile equipment), recorded in an International Registry: the Cape Town Convention.
  • Someone deliberately damages a radio navigation aid near an airport, putting aircraft in flight at risk.
  • Destroying or damaging air navigation facilities is one of the offences Montreal 1971 added.
  • Crimes against aviation

Memory hook: In date order the crimes grow: on board (1963), seizing the aircraft (1970), sabotage (1971).

Takeaway: Hague for hijacking, Montreal 1971 for sabotage, Tokyo for offences on board; Warsaw or Montreal 1999 for passengers, Rome for the ground.

What does the Tokyo Convention cover?

Tokyo 1963

Offences on board, who has jurisdiction, and the commander's powers.

  • Tokyo Convention 1963 offences on board The treaty about crimes and unruly behaviour on board. Signed in Tokyo on 14 September 1963, and India has ratified it.
    • Scope Art. 1 What the Convention covers, and what it leaves out.
      • Penal offences Crimes under criminal (penal) law committed on board.
      • Acts against safety or order Acts that put the aircraft's safety, or good order and discipline on board, at risk, even if they are not crimes.
      • Excluded aircraft military, customs, police It does not apply to aircraft used for military, customs or police work.
      • Political offences Art. 2 Nothing in it allows action for offences of a political kind, or based on racial or religious discrimination.
    • Two meanings of 'in flight' Arts 1 and 5 A trap: 'in flight' means two different things depending on which part of the Convention you are reading.
      • Jurisdiction rules power on to end of landing run For deciding who has legal power over an offence: from the moment power is applied for take-off until the landing run ends.
      • Commander's powers doors closed to doors open For the captain's powers: from the moment all outside doors are closed after boarding until one is opened. After a forced landing, until the authorities take over.
    • Jurisdiction Arts 3 and 4 Jurisdiction means the legal power to deal with an offence. Who has it for offences on board?
      • State of registration Art. 3 The country where the aircraft is registered can deal with offences committed on board.
      • Another State may interfere only if Art. 4, five cases Another country may step in only in five cases: the offence affects its territory; involves its citizen or resident; is against its security; breaks its flight rules; or a treaty requires it.
    • Commander's powers Arts 6 and 7 For the captain's powers: from the moment all outside doors are closed after boarding until one is opened. After a forced landing, until the authorities take over.
      • Reasonable measures and restraint Art. 6 With reasonable grounds, the captain may take reasonable steps, including restraining a person, to protect safety, keep order, or hand the person to the authorities.
      • Crew required, passengers requested Art. 6(2) The captain may order crew to help, but may only ask passengers, not order them.
      • Restraint ends at landing, unless Art. 7, three cases Restraint stops at landing, except in three cases: a non-member country refuses to let the person off; a forced landing leaves no authority to take over; or the person agrees to be carried on.
      • Notify before landing Art. 7(2) If possible before landing, the captain tells that country's authorities that a restrained person is on board, and why.

Takeaway: Registry State has jurisdiction. Commander may restrain, require crew help, request passenger help, and notify before landing.

How long does it take to leave a convention?

Leaving a convention

Written notice to ICAO as depositary, which informs every other State.

  • Montreal 1999 The carrier liability convention has the shorter notice period. Reference: Art. 54(2).
  • Tokyo, Hague, Montreal 1971, Protocol 1988, Beijing Every security-related convention uses 6 months' notice. Articles: Tokyo 25(2), Hague 15(2), Montreal 1971 17(2), Protocol 1988 10(2), Beijing 25(2).
  • Written notice to ICAO A country leaves a treaty by writing to ICAO, which keeps the treaty, and ICAO then tells every other member.

Takeaway: Security conventions: 6 months. Montreal 1999 carrier liability: 90 days. Always in writing, always to ICAO.
