CAS 2023/A/10069 — Club Jorge Wilstermann v. Gustavo Alexandre Barbosa do Nascimento & FIFA

"Wilstermann" · CAS confirmed that a signed 'pre-contract' containing all essentialia negotii is a binding employment contract, upholding USD 40,190 compensation and a two-registration-period ban on the Bolivian club.

What happened in Wilstermann

Brazilian professional footballer Gustavo Alexandre Barbosa do Nascimento negotiated with Bolivian club Club Jorge Wilstermann (CJW) in January 2023 via WhatsApp with the club's President (Gary Soria) and newly appointed Sporting Director (Adeval Borba). The club sent the player a document titled 'Pre Contrato' covering duration (January–December 2023), salary (USD 4,500/month), and other terms. The player signed and returned it on 7 January 2023. Relying on the club's promises of flight tickets, the player terminated his existing contract with Thai club Ayutthaya United on 10 January 2023. The club never sent the tickets, never signed the contract, and never responded to four default notices. The player filed a claim before the FIFA DRC, which awarded USD 40,190 compensation and imposed a two-consecutive-registration-period ban on CJW. CJW appealed to CAS, arguing no valid contract existed, that Borba lacked authority, and that the club acted in good faith. Sole Arbitrator Clariá dismissed the appeal in full, confirming the FIFA DRC decision. The case matters because it reinforces that a document labelled 'pre-contract' is legally a final employment contract if it contains all essentialia negotii, that apparent authority under Swiss law can bind a club, and that Article 18.3 RSTP voids medical-examination conditions precedent.

Procedural history of CAS 2023/A/10069

On 12 June 2023, the player lodged a claim before the FIFA Dispute Resolution Chamber (DRC) alleging breach of the Precontract and requesting USD 52,878 in compensation. The FIFA DRC issued its decision (grounds notified 29 September 2023), partially accepting the claim: it ordered CJW to pay USD 40,190 as compensation for breach of contract without just cause and imposed a ban from registering any new players, either nationally or internationally, for two entire and consecutive registration periods. On 20 October 2023, CJW filed a Statement of Appeal with CAS under Article R48 of the CAS Code, also requesting a stay of the registration ban. On 19 December 2023, the Sole Arbitrator granted the stay. The parties agreed to a Sole Arbitrator. An Appeal Brief was filed on 14 November 2023; Answers were filed by the First Respondent on 26 January 2024 and by FIFA on 29 January 2024. A videoconference hearing was held on 9 April 2024. CAS was asked to set aside the DRC decision in its entirety.

Key holdings in CAS 2023/A/10069

• A document labelled 'Pre Contrato' constitutes a final and binding employment contract if it contains all essentialia negotii (parties, duration, remuneration, and object), regardless of its title.
• Under Swiss law and the principle of apparent authority (procuration apparente), a club is bound by negotiations conducted by its Sporting Director where the club's President endorsed those negotiations and sent the same contractual document to the player.
• Pursuant to Article 18.3 FIFA RSTP, a condition making an employment contract subject to a successful medical examination is null and void; a club cannot invoke such a condition to deny the existence of a binding agreement.
• A club's signature is not a mandatory element for a valid employment contract under Swiss law (Articles 11.1 and 320 SCO); the player's countersignature and return of the offer constitutes acceptance, making the contract binding on both parties.
• The FIFA DRC's imposition of a two-consecutive-registration-period ban under Article 17(4) RSTP for breach during the protected period was legitimate, and the club's internal political crisis and change of management do not constitute mitigating factors sufficient to eliminate the sporting sanction.

How the CAS panel reasoned

The Sole Arbitrator applied the 'comfortable satisfaction' standard of proof, consistent with established CAS jurisprudence on contractual employment disputes. On the identity of negotiating parties, the arbitrator noted that CJW had acknowledged the WhatsApp chats as authentic in its FIFA-level response, only disputing Borba's authority; the new CAS-level denial that negotiations occurred at all was a changed defence unsupported by any counter-evidence, and public statements by Soria and Borba themselves confirmed the negotiations. On authority, the arbitrator applied Swiss law on apparent representation (procuration apparente): the President's own transmission of the pre-contract document to the player was sufficient public endorsement of Borba's authority. On the pre-contract/contract distinction, the arbitrator followed CAS 2008/A/1589 and the FIFA RSTP Commentary, finding that where all essential terms are agreed the label 'pre-contract' is irrelevant. The medical-examination clause was voided under Article 18.3 RSTP, and in any event the club's own failure to provide flight tickets prevented fulfilment of that condition. The arbitrator rejected the club's late hearing-stage argument on mitigation of damages because it was not raised in the Appeal Brief and was unsupported by evidence. On sanctions, the arbitrator found the club failed to demonstrate that the DRC should not have exercised its discretion to impose the ban under Article 17(4) RSTP.

Why Wilstermann matters in CAS jurisprudence

Wilstermann consolidates several strands of CAS jurisprudence in a single award: (1) the label 'pre-contract' is legally irrelevant if all essentialia negotii are present; (2) apparent authority under Swiss law can bind a football club even without formal written delegation; (3) Article 18.3 RSTP renders medical-examination conditions precedent void; and (4) a club's internal political crisis and change of administration are not mitigating factors that eliminate sporting sanctions under Article 17(4) RSTP. The award also provides a comprehensive survey of the 'comfortable satisfaction' standard across multiple CAS decisions.

Frequently asked questions about Wilstermann

Can a document called 'pre-contract' be treated as a binding employment contract in CAS/FIFA proceedings?

Yes. In Wilstermann, the Sole Arbitrator held that the title 'Pre Contrato' does not determine the legal nature of the document. If the document contains all essentialia negotii — parties, duration, remuneration, and object — it constitutes a final and binding employment contract. The arbitrator relied on CAS 2008/A/1589 and the FIFA RSTP Commentary, which define a true pre-contract as one where the parties have not yet agreed on essential elements.

Does a club's signature need to appear on an employment contract for it to be valid under FIFA/CAS rules?

No. In Wilstermann, the Sole Arbitrator confirmed that under Articles 11.1 and 320 of the Swiss Code of Obligations a signature is not a mandatory element of an employment contract. The player's countersignature and return of the offer constituted acceptance, making the contract binding on both parties. The club's failure to return a signed copy did not invalidate the agreement.

Can a club avoid liability for breach of a pre-contract by arguing its new management was unaware of the negotiations?

No. In Wilstermann, CJW argued that its new management had no access to the email account used by the former president and was therefore unaware of the player's default notices. The Sole Arbitrator rejected this, finding that internal administrative conflicts between former and current administrations cannot be used to undermine the player's rights, and that notification is effective when it enters the recipient's sphere of control. The club's internal crisis was not a mitigating factor sufficient to eliminate the two-registration-period ban.

Is a medical examination clause in a football employment contract enforceable under FIFA RSTP?

No. Article 18.3 FIFA RSTP prohibits making an employment contract subject to a successful medical examination. In Wilstermann, the Sole Arbitrator declared the medical-examination condition in Article 2 of the pre-contract null and void. The arbitrator further noted that even if the condition were valid, its non-fulfilment was solely the club's fault because the club failed to provide the player with flight tickets to travel to Bolivia for the examination.
