Liability Convention, 1972
"The international space-law treaty under which a launching state bears absolute liability for damage its space object causes on the surface of the Earth or to aircraft in flight."
The Convention on International Liability for Damage Caused by Space Objects, or Liability Convention, 1972, elaborates the liability principle embedded in the Outer Space Treaty, 1967. It provides that a 'launching state' bears absolute liability, liability regardless of fault, for damage caused by its space object on the surface of the Earth or to an aircraft in flight. For damage occurring elsewhere (such as in outer space, to another space object), liability is instead fault-based. The absolute-liability standard is the key operative link explaining why states regulate private space activity so closely: because a launching state is liable regardless of fault for surface damage caused by any of its space objects, including those of private companies, it has a direct sovereign interest in ensuring that any private operator whose object might land on someone is both technically competent and financially able to cover the resulting claim. India's 2026 IN-SPACe re-entry guidelines domesticate this absolute-liability exposure by passing it through to the private operator, requiring a demonstrated casualty-risk threshold below 1 in 10,000, mandatory third-party liability insurance where prescribed, and operator acceptance of absolute, no-fault liability, precisely because the Indian state itself carries that liability internationally under the 1972 Convention.
A precisely testable GS2/GS3 space-law instrument, essential for understanding why India regulates private launch and re-entry activity as closely as it does, and a natural pairing with the Outer Space Treaty in Prelims fact-matching.
- 1 Full name: Convention on International Liability for Damage Caused by Space Objects, 1972.
- 2 A launching state bears absolute liability for damage on the Earth's surface or to aircraft in flight.
- 3 Liability for damage elsewhere (e.g., in outer space) is fault-based, not absolute.
- 4 Explains why states closely regulate private space operators: the state itself is liable regardless of fault.
- 5 Directly operationalised by India's 2026 IN-SPACe re-entry guidelines (casualty-risk threshold, mandatory insurance, operator no-fault liability).
- 6 Works alongside the Outer Space Treaty, 1967's state-responsibility principle.
Because India as a launching state carries absolute liability under the Liability Convention, 1972 for any surface damage its space objects cause, IN-SPACe's 2026 re-entry rules require operators to demonstrate a casualty risk below 1 in 10,000 and to accept absolute, no-fault liability themselves.
