Explainer: What is CAS? Where Nigeria, Senegal plan to appeal football rulings

The Court of Arbitration for Sport (CAS) has once again come into global focus as both Nigeria and Senegal have announced decisions to challenge what they term controversial football decisions affecting their fortunes on the international stage. For Nigeria, which has participated six times (1994, 1998, 2002, 2010, 2014, 2018), Nigeria is weighing a legal battle after FIFA dismissed its protest over alleged ineligible players fielded by DR Congo in the 2026 Africa World Cup qualifying play-off. Nigeria lost the encounter 4-3 on penalties after both teams were tied at 1-1 following regulation and extra time, prompting the NFF to lodge a formal protest alleging irregularities in the issuance of passports that qualified some DR Congo players for the fixture. However, on Tuesday, FIFA dismissed Nigeria’s petition. Reacting, NFF General Secretary Mohammed Sanusi, in a statement, said that the federation was dissatisfied with the ruling and determined to pursue justice through FIFA’s appellate process. “We respect FIFA but firmly disagree with this decision. We believe there are strong grounds for appeal and will present additional evidence,” Sanusi said. In another move, the Confederation of African Football (CAF) Appeal Board has upheld Morocco’s protest and ruled that Senegal forfeited the final of the 2025 Africa Cup of Nations, officially awarding the match 3-0 to Morocco. The decision overturns an earlier ruling by the CAF Disciplinary Board and follows an appeal lodged by the Fédération Royale Marocaine de Football (FRMF) regarding incidents during the final. Reacting, the Senegalese Football Federation (FSF) strongly condemned the March 17, 2026 ruling by the Confederation of African Football (CAF) Appeals Board and announced it will appeal the decision to the Court of Arbitration for Sport (CAS) in Lausanne. But what exactly is CAS, and why is it often described as the final court in sports? The “Supreme Court” of world sport Established in 1984 and headquartered in Lausanne, Switzerland, CAS is an independent international body set up to resolve disputes in sport. Often referred to as the “Supreme Court of sport”, it handles cases involving players, clubs, federations and governing bodies across the world. Its jurisdiction is recognised by major organisations such as FIFA, meaning that decisions taken by football authorities can be challenged at CAS as a final step. What cases does CAS handle, and who can submit a dispute? According to CAS, any dispute related to sport, whether it involves disciplinary matters arising from decisions by sports bodies or contractual disagreements. Also, individuals and legal entities with a legitimate interest, including athletes, clubs, federations, event organisers, sponsors and broadcasters, are eligible to file claims or appeals before the court. Types of CAS procedure According to CAS, there are four cases which are An ordinary arbitration procedure is a dispute that is referred to CAS because the parties have an arbitration clause in a contract or in the statutes of a sports federation. Ordinary procedures can also be used by parties agreeing to have their procedure heard before CAS on a one-off basis. An appeals arbitration procedure is an appeal against a decision that has first been rendered by a federation or sports body. In this instance, the federation or sports body will have a specific arbitration clause in their statutes that makes legal allowance for an appeal to CAS. A procedure with the CAS Anti-Doping Division is a legal procedure related to doping, whereby CAS acts as a first-instance authority to rule on whether a doping offence has been committed. This authority comes from a delegation of powers by the International Olympic Committee, the Olympic International Federations, and other signatories to the World Anti-Doping Code. CAS also provides mediation services. This is a non-binding and informal procedure where each party attempts to negotiate in good faith to settle the dispute with the assistance of a CAS mediator. Disputes related to disciplinary matters such as doping issues, match-fixing and corruption are generally excluded from CAS mediation. How long does CAS arbitration last? Under CAS procedures, ordinary arbitration cases typically last between 12 and 18 months, while appeal cases are resolved more quickly, averaging between six and nine months. In such instances, final rulings are usually delivered within four months after the conclusion of hearings or evidentiary proceedings. In urgent situations, CAS can also grant interim measures within a short timeframe, including suspending the enforcement of a decision by a sports federation or governing body pending the final determination of the case. How CAS decisions work Appeals to CAS must typically be filed within 21 days of a ruling. Once a case is accepted, a panel of arbitrators reviews evidence, hears arguments from both sides and delivers a binding decision. Can an appeal be made against CAS ruling? All decisions of the Court of Arbitration for Sport (CAS) are subject to limited review by the Swiss Federal Tribunal, the highest court in Switzerland. However, the tribunal does not rehear cases on merit. It can only set aside a CAS ruling under specific conditions, including where the arbitration panel was improperly constituted, wrongly accepted or declined jurisdiction, exceeded its mandate, or failed to rule on key claims. Also, a CAS award may also be overturned if the principle of fair hearing was violated, including denial of equal treatment of the parties, or if the decision is found to be incompatible with public policy.
