Indian sprinter Dutee Chand, who has been at the center of the gender controversy, has been allowed to race after International Association of Athletes Federations (IAAF) made a landmark ruling questioning the validity of the gender tests around naturally high testosterone levels in female athletes.
Chand, who has been banned since last summer after failing a hormone test, will be allowed to compete for the next two years, the BBC reported.
Court of Arbitration for Sport (CAS) on Monday declared the rule, which debar athletes with hyperandrogenism competing in the female category, invalid.
In July last year, the Athletics federation of India had applied the initial suspension on Chand in accordance with the IAAF's guidelines on women testing for high levels of naturally-occurring testosterone.
However, Indian champion's legal team argued the ruling was discriminatory and flawed at a hearing in March.
