The Court of Arbitration for Sport (CAS) has confirmed it will operate an Ad Hoc Division for the duration of the 2026 FIFA World Cup, providing a rapid arbitration mechanism capable of issuing binding decisions within 24 hours of a case being filed.

The Ad Hoc Division is a standard fixture at major tournaments, but its importance scales with the tournament's complexity. With 48 teams participating - up from 32 in 2022 - the volume of potential eligibility disputes, passport and nationality challenges, anti-doping violations, and disciplinary appeals is materially higher than any previous edition.

Cases the CAS can adjudicate include: player eligibility challenges (nationality changes, dual nationality disputes), club versus national association conflicts over player release obligations, appeals against FIFA disciplinary decisions including red card bans, and anti-doping appeals where a player disputes a provisional suspension before a match.

Historically, CAS Ad Hoc decisions at World Cups have occasionally had direct market impact - most notably in 2006 and 2014 when eligibility rulings affected squad availability for specific matches in the days before fixtures. Bettors should monitor the CAS website's real-time decisions register (tas-cas.org) during the tournament as a supplementary data source alongside team news.
