CAS 2025/A/11508 — Jefferson Tavares da Silva v. Club Deportivo Jorge Wilstermann & FIFA

"Tavares da Silva" · CAS confirmed FIFA DRC lacked jurisdiction where dual-national player was registered and competed as a Bolivian, not a foreign, player.

What happened in Tavares da Silva

Jefferson Tavares da Silva, a dual Brazilian-Bolivian national, signed two contracts dated 8 January 2024 with Bolivian club Jorge Wilstermann: a Registered Contract (identifying him by Bolivian documents) and a Private Contract (referencing his Brazilian passport but calling him a 'naturalized Bolivian'). He was registered with the FBF via COMET as a Bolivian player, occupied a national player quota, and never counted as a foreign player during the 2024 season. After alleging unpaid wages, he terminated the employment on 17 December 2024 and filed a DRC claim seeking USD 58,050 in outstanding salaries, USD 119,000 in residual-contract compensation, and USD 27,000 in additional compensation. On 3 April 2025 the DRC declined jurisdiction, finding the dispute lacked an international dimension because the player was registered under the same nationality as the club. The player appealed to CAS, arguing his Brazilian nationality and the Private Contract should prevail. The Sole Arbitrator dismissed the appeal, confirming that 'sportive nationality' — determined by registration and effective sporting situation — is the decisive criterion under Article 22 RSTP, and that contractual references to nationality cannot override objective registration facts. The case matters because it reinforces that dual nationality alone is insufficient to create FIFA jurisdiction and that a player who benefits from a domestic registration cannot later invoke a foreign nationality to manufacture an international dimension.

Procedural history of CAS 2025/A/11508

On 17 December 2024 the Appellant terminated his employment with Jorge Wilstermann and on the same date lodged a claim before the FIFA Dispute Resolution Chamber (DRC) seeking outstanding remuneration and compensation for breach of contract. The First Respondent objected to DRC jurisdiction, arguing the dispute lacked an international dimension given the Appellant's registration as a Bolivian player. The FBF confirmed via documentation that the Appellant had been registered as a Bolivian player using Bolivian identity documents and had occupied a Bolivian player slot throughout the 2024 season. On 3 April 2025 the DRC rendered the Appealed Decision, declaring it lacked jurisdiction because the player was registered under the same nationality as the club, making the dispute purely domestic. The grounds were notified on 16 May 2025. On 6 June 2025 the Appellant filed a Statement of Appeal before CAS, and on 16 June 2025 filed his Appeal Brief, requesting that the Appealed Decision be set aside and FIFA jurisdiction be recognised, or alternatively that CAS decide the merits.

Key holdings in CAS 2025/A/11508

• Under Article 22 lit. b) of the RSTP, FIFA jurisdiction over employment disputes requires an international dimension, which is absent when the player is registered and competes under the same nationality as the club.
• In cases of dual nationality, the player's 'sportive nationality' — determined by the nationality under which he is registered and competes — is the decisive criterion for assessing international dimension, not the mere possession of a foreign passport.
• Contractual references to a player's nationality do not, in and of themselves, determine his nationality for football purposes and cannot override the objective fact of his federative registration.
• A player who has benefited from registration as a domestic player cannot subsequently invoke an alternative nationality to artificially create FIFA jurisdiction; such conduct is inconsistent with the principle of good faith.
• A unilaterally signed, late-submitted alleged 'pre-contract' has no probative value for determining international dimension and cannot displace the evidentiary weight of the player's registration and effective sporting situation.

How the CAS panel reasoned

The Sole Arbitrator applied the 'sportive nationality' doctrine drawn from CAS jurisprudence, holding that the assessment of international dimension under Article 22 RSTP must rest on objective and verifiable elements — principally the nationality under which the player is registered and competes — rather than on civil nationality or contractual characterisations. He noted that CAS 2020/A/6933 linked sportive nationality to 'the concrete situation of the registration of a player' and that CAS 2010/A/1996 held dual nationality alone to be 'clearly inadequate' to establish FIFA jurisdiction. The Sole Arbitrator rejected the Appellant's reliance on the Private Contract, finding that both the Registered Contract and the Private Contract contained references to the Appellant's Bolivian status, and that allowing contractual drafting to determine jurisdiction would undermine uniform application of the RSTP. He also rejected the argument that registration occurred without the Appellant's knowledge, noting the Appellant bore the burden of proof (CAS 2016/A/4441) and had not discharged it, and that in any event jurisdiction must be assessed on objective criteria, not subjective assertions (CAS 2020/A/6791). The alleged pre-contract was dismissed as unilaterally signed and submitted late. The Sole Arbitrator concluded that the dispute was purely domestic and confirmed the DRC's decision.

Why Tavares da Silva matters in CAS jurisprudence

This award consolidates the CAS doctrine that 'sportive nationality' — grounded in federative registration and effective sporting situation — governs the international-dimension test under Article 22 RSTP, and that dual nationality is insufficient on its own. It also establishes that a player who has actively benefited from a domestic registration cannot later invoke a foreign nationality to manufacture FIFA jurisdiction, reinforcing the principle against opportunistic forum selection in international football disputes.

Frequently asked questions about Tavares da Silva

Why did FIFA DRC decline jurisdiction in the Tavares da Silva case?

The DRC found that the dispute lacked an international dimension because the Appellant was registered with the FBF as a Bolivian player, occupied a Bolivian player slot, and was never considered a foreign player in any official competition during the 2024 season. Since both the player and the club were affiliated to the same national association under the same nationality, the DRC held the dispute was purely domestic and therefore inadmissible before FIFA.

Does holding dual nationality automatically give a player access to FIFA DRC jurisdiction?

No. CAS confirmed in this case, citing CAS 2010/A/1996, that the dual nationality of a player is 'clearly inadequate' to justify FIFA jurisdiction. The decisive criterion is the player's 'sportive nationality' — the nationality under which he is actually registered and competes — not the mere possession of a foreign passport or civil nationality.

Can a player use a contract that identifies him by a foreign nationality to establish FIFA DRC jurisdiction when he was registered domestically?

No. The Sole Arbitrator held that contractual references to nationality do not determine a player's nationality for football purposes and cannot override the objective fact of federative registration. Both the Registered Contract and the Private Contract in this case contained references to the Appellant's Bolivian status, and allowing contractual drafting to control jurisdiction would undermine the uniform application of the RSTP.

What happens if a player claims he was registered as a domestic player without his knowledge — does that affect the international dimension analysis?

It does not alter the outcome. The Sole Arbitrator held that the assessment of international dimension must be based on objective criteria, including registration and effective sporting situation, and cannot depend on unilateral or ex post facto assertions by one party (citing CAS 2020/A/6791). The Appellant also bore the burden of proving lack of knowledge (CAS 2016/A/4441) and failed to discharge it.
