The Judicial System of the International Tennis Federation (ITF) forms part of a book edited by Michele Colucci and Massimo Coccia entitled “International and Comparative Sports Justice” (Sports Law and Policy Bulletin, May 2023). The Author analyses the dispute resolution system of the ITF through its various decision-making bodies and examines issues related to jurisdiction, applicable law, composition of its members, sanctions and enforcement of its decisions. Unlike other major international Olympic federations that are based in Switzerland, the ITF is seated in London (UK) and its major decision-making body, namely the ITF Independent Tribunal, is administered by Sport Resolutions, an independent case management organization based in London (UK). The ITF has also delegated its doping-control and education responsibilities and its monitoring and prosecution of anti-corruption offences to an independent organization (International Tennis Integrity Agency).
