Content

The Convention does not apply to customs, law enforcement or military aircraft, thus it applies exclusively to civilian aircraft. The Convention criminalises the following behaviour: #Committing an act of violence against a person on board an aircraft in flight if it is likely to endanger the safety of the aircraft; #destroying an aircraft being serviced or damaging such an aircraft in such a way that renders it incapable of flight or which is likely to endanger its safety in flight; #placing or causing to be placed on an aircraft a device or substance which is likely to destroy or cause damage to an aircraft; #destroying or damaging air navigation facilities or interfering with their operation if it is likely to endanger the safety of aircraft; #communicating information which is known to be false, thereby endangering the safety of an aircraft in flight; #attempting any of 1–5; and #being an accomplice to any of 1–6. The Convention sets out the principle of '' aut dedere aut judicare''—that a party to the treaty must either (1) prosecute a person who commits one of the offences or (2) send the individual to another state that requests his or her
extradition Extradition is an action wherein one jurisdiction delivers a person accused or convicted of committing a crime in another jurisdiction, over to the other's law enforcement. It is a cooperative law enforcement procedure between the two jurisdi ...
