Greek basketball legal and administrative disputes

Legal and administrative tensions have escalated between major Greek basketball clubs and governing bodies, involving both domestic and international complaints.

Olympiacos BC has filed dual complaints with the EuroLeague and the Hellenic Basketball Clubs Association (ESAKE) against Panathinaikos AKTOR and its owner, Dimitris Giannakopoulos. These complaints stem from incidents during a match against Baskonia on October 22, 2026, where Olympiacos alleges that Panathinaikos supporters displayed offensive banners and chanted derogatory slogans. Specifically, the club cites a banner containing derogatory language directed at Piraeus and chants involving referee Vasiliki Tsarouha and coach Georgios Bartzokas.

Additionally, Olympiacos is targeting Giannakopoulos for his social media activity on Instagram, characterizing his posts as defamatory, insulting, and threatening. The club argues that his remarks regarding the coach and references to judicial investigations regarding match-fixing allegations damage the reputation and dignity of the club. Giannakopoulos has dismissed these accusations as baseless, stating his posts were not intended to defame the sport. He has accused Olympiacos management of being ‘uneducated’ and questioned their integrity regarding past legal disputes.

In a related legal development, Olympiacos announced that a lawsuit filed by Despoina Giannakopoulou against Vice President Giorgos Skindilias—stemming from incidents during the 2025 Basket League playoffs—was ruled groundless and permanently archived. While the club noted its preference for the Greek judicial system over social media discourse, it stated that the actions of Dimitris Giannakopoulos have been referred to the competent court for further judgment.

Parallel to these allegations, Panathinaikos AKTOR continues its legal efforts regarding the Hellenic Basketball Referees Association (ODKE). Following a previous denial of document requests, the club successfully utilized a court order from the Athens Court of First Instance to secure sensitive refereeing documents to investigate alleged irregularities.
