The article deals with the issue of the Beijing reform of international criminal aviation law. The author analyses the relevant applicable international law and confronts it with the new legal regulations adopted at the International Civil Aviation Organisation (ICAO) conference in Beijing in 2010. As a result, the author states that the basic change involves the expansion of the catalogue of acts subject to criminalisation as well as the expansion of the circle of persons participating in or supporting actions involving the commission of acts that pose a threat to the safety of civil aviation; the system also specifies the responsibility of collective entities (the so-called ‘Al Qaeda’ clause). The author is deeply convinced that the development of the Tokyo-Hague-Montreal-Beijing system, which is part of the whole international legal system of combatting terrorism, including its financing, is fully justified. The new regulations also make this system more coherent. It is also worth adding that the adoption of the Beijing Convention and the Beijing Protocol is part of the implementation of the Global Counter-Terrorism Strategy adopted by the United Nations.
