The World Anti-Doping Agency (WADA) closed its eight-year hunt of Russia's state-run doping program with 291 Russian athletes sanctioned across 22 sports, the agency announced on 30 April. The investigation, known as Operation LIMS, produced 302 sanctions in total — with 11 athletes sanctioned twice for separate violations — and rests on 24 terabytes of data WADA's investigators retrieved from the Moscow Anti-Doping Laboratory in 2019. WADA's president called it the most successful investigation in the history of anti-doping.
Eight years, 22 sports, and a deleted-then-recovered database
WADA confirmed on 30 April that all Operation LIMS cases have now been investigated. The 302 sanctions were imposed by 23 anti-doping organizations, with four additional cases charged but not yet resolved.
Most cases concentrated in two sports: weightlifting accounted for 107 sanctioned athletes and athletics for 93. Wrestling produced 19 sanctions and volleyball eight. Smaller numbers came from biathlon, bobsleigh and skeleton, boxing, canoe, football, ice hockey, judo, powerlifting, rowing, skating, taekwondo, archery, kettlebell, pentathlon, sambo, skiing, triathlon and aquatics.

WADA President Witold Bańka said Operation LIMS is the most successful investigation in anti-doping history. He said an incredible 302 sanctions have now been imposed in the wake of Russia's institutionalized doping scheme. He credited the work to WADA's intelligence, investigations, and legal departments alongside partner anti-doping organizations.
How the Moscow lab data left Russia
WADA first ruled RUSADA non-compliant with the World Anti-Doping Code in 2015 after uncovering widespread institutionalized doping in Russian sport. In September 2018, WADA's Executive Committee voted to reinstate RUSADA subject to strict conditions — a move that was opposed by a vocal minority at the time. Bańka said that decision was made precisely to get to the truth and that without it WADA would never have secured the Moscow Laboratory evidence the cases were built on.

The reinstatement opened the door for WADA's missions to Russia in January 2019 and April 2019, which retrieved 24 terabytes of data from the Moscow Anti-Doping Laboratory's information-management system, plus a number of samples. The agency notes that 24 terabytes is roughly equivalent to about 8,000 HD movies.
WADA says investigators found during authentication that parts of the data had been altered, prompting WADA to bring a new compliance case against RUSADA.The Court of Arbitration for Sport in December 2020 backed WADA's case but ordered milder consequences than the agency had sought, lasting two years instead of four. Forensic recovery of the deleted and manipulated data underpinned hundreds of cases against athletes tied to Russia's doping program.

RUSADA still non-compliant
To this day, RUSADA still has not been restored to compliance and must meet all the reinstatement conditions set by the December 2020 CAS ruling. An in-person WADA audit team is required to verify compliance, but the ongoing geopolitical situation has blocked the visit. CAS is also considering a separate WADA compliance case over inconsistencies in Russian sports legislation.
