1. Core Legal Answer & Context: Hijacking Definition: Hijacking, in the context of aviation, refers to the unlawful seizure or exercise of control of an aircraft in flight by force, threat, or any other form of intimidation. It is an act of air piracy, a serious international crime that endangers the safety of civil aviation, passengers, and crew. The act typically involves diverting an aircraft from its intended course or taking control of it against the will of the pilot or crew.

The Hague Convention for the Suppression of Unlawful Seizure of Aircraft, 1970: The Hague Convention is a multilateral treaty adopted under the auspices of the International Civil Aviation Organization (ICAO) in response to a surge in aircraft hijackings in the late 1960s. Its primary aim is to ensure that perpetrators of unlawful seizure of aircraft are either prosecuted or extradited, thereby preventing safe havens for such criminals. It establishes a framework for international cooperation to combat this specific form of terrorism.

Main Provisions of the Hague Convention, 1970:

• Article 1 (Definition of the Offence): Defines the offence of unlawful seizure of aircraft. It states that any person who, on board an aircraft in flight, unlawfully, by force or threat thereof, or by any other form of intimidation, seizes or exercises control of that aircraft, or attempts to do so, or is an accomplice of a person who performs or attempts to perform such an act, commits an offence.
• Article 2 (Penalties): Requires each Contracting State to make the offence punishable by severe penalties.
• Article 3 (Scope of Application): Specifies that the Convention applies to an aircraft in flight, from the moment all its external doors are closed following embarkation until the moment any such door is opened for disembarkation. It also applies irrespective of whether the aircraft is engaged in international or domestic flight, provided the place of take-off or the place of actual landing of the aircraft is situated outside the State of registration of that aircraft, or if the offender is found in the territory of a State other than the State of registration.
• Article 4 (Jurisdiction): Establishes a broad jurisdictional basis for Contracting States. A State must establish jurisdiction if:
  • The offence is committed on board an aircraft registered in that State.
  • The aircraft lands in its territory with the offender still on board.
  • The offender is present in its territory.
  • The offence is committed on board an aircraft leased without crew to a lessee whose principal place of business or, if he has no such place of business, whose permanent residence is in that State.
• Article 6 (Custody of Offender): Requires any Contracting State in whose territory the offender is found to take him into custody or take other measures to ensure his presence. This custody is for the purpose of prosecution or extradition.
• Article 7 (Aut Dedere Aut Judicare - Extradite or Prosecute): This is a cornerstone provision. It obliges the Contracting State in whose territory the alleged offender is found, if it does not extradite him, to submit the case to its competent authorities for the purpose of prosecution. This ensures that no safe haven is provided for hijackers.
• Article 8 (Extradition): Specifies that the offence shall be deemed to be an extraditable offence in any extradition treaty existing between Contracting States. If no such treaty exists, the Convention itself can serve as a legal basis for extradition.
• Article 10 (Assistance): Contracting States are required to afford each other the greatest measure of assistance in connection with criminal proceedings brought in respect of the offence.

2. Relevant Statutes and Sections:

• Hague Convention for the Suppression of Unlawful Seizure of Aircraft, 1970.
• In India, the Anti-Hijacking Act, 2016, implements the provisions of the Hague Convention and the Beijing Protocol, 2010, making hijacking a capital offence in certain circumstances.

3. Important Landmark Cases: While the Hague Convention is a foundational treaty in international criminal law, there are no specific ICJ cases directly interpreting its provisions. Its impact is primarily seen in national prosecutions and extradition proceedings based on its framework.

4. Clear Conclusion: Hijacking, defined as the unlawful seizure of an aircraft in flight, is a grave international crime. The Hague Convention of 1970 is a pivotal international instrument designed to combat this threat. Its main provisions establish a clear definition of the offence, mandate severe penalties, create a broad framework for jurisdiction, and, most importantly, impose the 'extradite or prosecute' obligation on signatory states. By ensuring that hijackers cannot escape justice, the Convention significantly contributes to the safety and security of international civil aviation and serves as a model for international cooperation against transnational crimes.
