The case revolves around a dispute between Club Deportes Tolima S.A. and FC Honka concerning the validity of a player's employment contract and subsequent claims for training compensation. The player, initially signed by Tolima in 2017, later contested a second contract, arguing it was invalid as it was signed while he was a minor without parental consent. The player terminated his relationship with Tolima in 2020, claiming his contract had expired, and subsequently joined FC Honka. Tolima filed a claim with FIFA's Dispute Resolution Chamber (DRC) in 2021, seeking compensation for breach of contract and training compensation. The DRC rejected Tolima's claim, ruling the second contract was pre-dated and signed in bad faith, rendering the player a free agent when he joined Honka. Tolima appealed to the Court of Arbitration for Sport (CAS), but the sole arbitrator upheld the DRC's decision, emphasizing that the appeal could not expand beyond the original employment dispute. The arbitrator noted Tolima had not filed a separate claim for training compensation through FIFA's Transfer Matching System (TMS), as required, and thus the request was inadmissible. The case underscores the importance of adhering to procedural rules and the limitations on altering claims during appeals. The CAS ultimately dismissed Tolima's appeal, reaffirming the DRC's decision and closing the case without further action. This ruling highlights the procedural rigor in sports arbitration and the necessity for clubs to follow established protocols when addressing contractual disputes or training compensation claims.
