Russian figure skater Kamila Valieva has been denied permission to compete internationally once more, following a second review after her neutral status was revoked.On Thursday, the International Skating Union confirmed that Valieva was one of four Russian 2022 Olympians deemed not to "satisfy the requirements to participate as Individual Neutral Athletes." The decision also applies to men's skater Mark Kondratiuk, as well as the ice dance team of Alexandra Stepanova and Ivan Bukin. The governing body offered no specific reasons for the four rejections."The ISU will not comment further on individual cases while any applicable appeal rights remain available," the federation said in a statement.This latest career obstacle arrives more than four years after controversy surrounding Valieva’s positive doping test overshadowed the 2022 Beijing Winter Olympics.Valieva and her fellow skaters have three weeks to lodge an appeal with the Court of Arbitration for Sport. Neither Valieva nor the Russian figure skating federation provided an immediate response or comment.Valieva’s positive doping test overshadowed the 2022 Winter Olympics (Andrew Milligan/PA) (PA Wire)The ISU has permitted a greater number of Russians to compete as neutral athletes this season, having initially barred most following the invasion of Ukraine. Official policy dictates that competitors are "presumed eligible unless they fall within the disqualifying criteria."This policy structure has meant that skaters such as Valieva were briefly deemed eligible after filing the necessary paperwork for neutral status, only for that status to be revoked shortly afterwards.Skaters from Russia and its ally Belarus were originally barred by the ISU in 2022, though a limited number were permitted to return for last season's qualifying event and the Milan Cortina Olympics. Two Russian figure skaters, Adeliia Petrosian and Petr Gumennik, took part in the Games as neutrals without national flags or symbols, though neither achieved a medal.According to ISU rules, neutral status can be refused if skaters serve in military or security forces, have joined military operations against Ukraine, or have "actively and publicly supported that war" since 2022.Separately, Valieva is taking legal action regarding the procedure surrounding her doping ban, which concluded late last year.A document published on Monday by the European Court of Human Rights revealed that Valieva has brought a claim against Switzerland over a Swiss supreme court ruling from last year, when she attempted to overturn her suspension.The ECHR document notes that Valieva's claim alleges the Swiss court breached her rights by refusing to evaluate supposed new evidence in her favour. During those proceedings, her legal team cited an Associated Press article from September 2024 to allege that the World Anti-Doping Agency suppressed evidence.
