Liability in International Air Law: The Problem of Fragmentation

The article investigates one of the most pressing and complex issues in contemporary international air law: the fragmentation of the legal framework governing legal liability. The author points out that legal liability is a crucial component of the legal regulation mechanism, and any shortcomings directly affect the overall effectiveness of international air law. The research establishes that the problem of fragmentation manifests itself in two main dimensions. First, in terms of spatial application and the scope of entities involved, since international treaties apply exclusively to state-parties and lack a truly universal character. Second, based on the subject of legal regulation, these norms belong to different, disconnected institutes and fail to form a single, cohesive system. The article highlights that while legal doctrines have extensively studied liability within specific discrete areas — such as the liability of states, air carriers, operators for third-party damage, unlawful interference, and environmental damage –a comprehensive systematic approach remains extremely rare. The main purpose of this study is to isolate the norms regulating liability to determine whether they currently constitute a holistic legal institute functioning as a complex open system. They regulate the international liability of public-law entities, primarily states ensuring compliance with ICAO standards, alongside private-law entities like aircraft operators, air carriers, and perpetrators of unlawful interference. The author proposes an alternative classification of liability based on the object of international legal protection. This includes aviation security against unlawful acts; flight safety and air navigation safety; operator liability; environmental safety characterized by a two-tier structure under CORSIA; and air carriage liability. Despite extensive codification across dozens of conventions, a holistic system acting as a singular institute of international air law has not been formed. The existing framework is highly fragmented: well-regulated in aspects like carriage liability, but poorly defined in others. The author concludes that a cohesive liability institute does not currently exist.

However, forming such a unified system in the future is deemed highly advisable. This integration would overcome the pervasive fragmentation of the legal field, significantly improving regulatory efficiency. The structure of this prospective institute should mirror the framework of international air law itself, comprising sub-institutes dedicated to airspace use, security, safety, and environmental protection.

Keywords: international air law, legal liability, fragmentation of the legal field, aviation security, flight safety, environmental safety of aviation, liability of the aircraft operator, liability of the air carrier.
