# CBV transgender athlete eligibility dispute > Live situation record from CLSTR: https://clstr.news/situations/cbv-transgender-athlete-eligibility-dispute > Updated: 2026-10-23T18:31:00.000Z. Sources: 27. Developments: 3. The Brazilian Volleyball Confederation (CBV) implemented a new eligibility policy for the female Superliga, requiring athletes to have been born with female biological sex in alignment with IOC and FIVB standards. This policy prevents transgender athlete Tifanny Abreu from participating in the 2026/27 season. Abreu, a player for Osasco São Cristóvão Saúde, criticized the federation for a perceived lack of empathy, stating, “It is as if I were a criminal, and I am not a criminal.” Following the restriction, Abreu and Osasco Voleibol Clube filed a legal appeal with the Sports Justice system. The defense is seeking an injunction to allow Abreu to compete in the Supercopa and the Superliga while the Superior Court of Sports Justice (STJD) reviews the case. The new rules involve testing for the SRY gene to determine eligibility for the female category. On October 16, 2026, a court in Rio de Janeiro granted a provisional injunction allowing Abreu to compete in the Supercopa and the 2026/2027 Superliga with Osasco. Judge Antonio Luiz da Fonseca Lucchese ordered the CBV to immediately register the athlete, stipulating a fine of R$ 5,000 per match if she is prevented from playing. The judge noted that immediate exclusion would cause “irreparable harm” to her career. Following this victory, Abreu participated in Osasco’s 3-0 win over Dentil Praia Clube to secure the Supercopa Feminina title. By October 19, the 44th Civil Court of Rio de Janeiro confirmed the provisional authorization to protect Abreu’s right to work. On October 23, the Rio de Janeiro State Court revoked the preliminary injunction that had permitted Abreu to compete. ## Claims - The court ordered the CBV to pay a fine of R$ 5,000 per match if Tifanny is prevented from playing.
