BAT reaches milestone of 2000 cases

We are delighted to announce that the Basketball Arbitral Tribunal (BAT) has just reached the milestone of a total of 2000 cases since its creation in 2007.
Our firm created the BAT at the behest of the International Basketball Federation (FIBA) and has been administering all BAT arbitrations ever since. The BAT is widely acknowledged as a highly innovative court of arbitration that has changed the landscape of dispute resolution in sport. Its success is underlined by the fact that despite BAT arbitration being entirely voluntary, and despite BAT proceedings being limited to financial disputes in basketball, its caseload arguably makes the BAT the second-biggest arbitral tribunal in sports world-wide. In recent years, the average number of cases per year was approximately 160. We are looking forward to many more years of BAT arbitration, and will do our best to help continuously improving this dispute resolution system for the benefit of its users.
