Olympic champion Caster Semenya has decided to end her seven-year legal battle. She fought over track and field’s sex eligibility rules; her lawyers announced the decision on Thursday. The move comes despite her recent victory at the European Court of Human Rights in July, which had seemed to reopen one of the most debated issues in global sport.

Patrick Bracher, Caster Semenya’s lawyer, wrote in an email to The Associated Press. He said they would not take her appeal to the Swiss Supreme Court. This step was open to them. However, many thought it would be her next move after the European Court of Human Rights ruling. But Semenya has chosen not to continue.

“Caster’s legal challenge reached the highest possible court with a highly successful outcome and will not be taken further in the circumstances,” Bracher wrote.

Semenya, the two-time Olympic gold medallist from South Africa, has been banned from the tracks since 2019 at the major international stages like the Olympics and World Championships. The step was taken due to a breach of the rules of World Athletics and taking medication to artificially reduce her hormone levels.

Since 2018, Caster Semenya has fought against the rules set by World Athletics in three different courts—the Court of Arbitration for Sport, the Swiss Federal Tribunal, and the European Court of Human Rights.

She argued that these rules violated her basic rights. However, she lost her cases at both the Court of Arbitration for Sport and the Swiss Federal Tribunal.

Later, the judgement of the European Court of Human Rights ruled in July, suggesting a lack of consideration of some complex arguments and dismissal of a fair hearing at the Swiss Tribunal. Which, in turn, opened an avenue for the runner to further challenge.

Semenya was once the world’s leading middle-distance runner, going unbeaten in more than 30 races before the ban. Now 34, she has turned to coaching, as the regulations effectively ended her competitive career.

She has simultaneously become the central figure in the debate over sex eligibility in sports. Her story took track in 2009, when she won the world championships as a teenager and was asked to undergo sex verification tests.

Semenya lives with a condition known as differences in sex development (DSD). People with DSD may have traits that don’t fit typical definitions of male or female. In her case, she has the XY chromosome pattern usually found in males, along with female physical traits and naturally high levels of testosterone. DSD conditions are sometimes described as intersex.
