Sabotage Convention and Montreal Protocol

(Montreal, September 23, 1971) Formally called the Convention for the Suppression of Unlawful Acts against the Safety of Civil Aviation. The Sabotage Convention goes beyond the Hijacking Convention by containing separate definitions of what constitutes an offense onboard aircraft, and specifying when that aircraft is “in service.” The Sabotage Convention places additional international legal obligations on states to act against a wider range of offenses involving aircraft. The United States ratified the Sabotage Convention on November 1, 1972. On February 24, 1988, an ICAO conference opened for signature a Protocol to amend the Montreal Convention of 1971. The Protocol provides for suppression of unlawful acts of violence at airports serving international civil aviation. A signatory to the Protocol, which finds an alleged perpetrator on its territory, must either take that person into custody for the purpose of prosecution, or proceed with extradition. The United States ratified the Airport Terrorism Protocol on November 18, 1994.
