Operation URRACA Investigation Report

This investigation performed a review into alleged breaches of the World Anti-Doping Code and departures from the International Standards, allegedly committed by the management of the Spanish Commission for the Fight Against Doping in Sports (CELAD). The allegations were found to be unsubstantiated. Although most of the cases reviewed were deemed to have been properly handled, Operation Urraca’s review identified certain issues requiring follow-up actions and CELAD has already acted on their own initiative to address these matters.

Operation OBSIDIAN Investigation Report

A joint investigation by the World Anti-Doping Agency’s (WADA’s) Intelligence and Investigations department and World Rugby investigated claims that players were engaging in sample substitution in blatant contravention of the rules, which resulted in anti-doping rule violations being confirmed against six players and one member of the athlete support personnel from the Georgia national rugby union team, and a loss of confidence by WADA in the Georgian Anti-Doping Agency due to a number of breaches of the World Anti-Doping Code.

13 March 2026

On 2 October 2024, WADA’s I&I Department concluded three interconnected investigations into allegations of performance enhancing drug (PED) trafficking, advance notice of testing, and other allegations involving three Anti-Doping Organizations (ADOs). Given the seriousness of the allegations including potential criminal activities, certain aspects were referred to a law enforcement agency, which subsequently launched its own investigation. WADA I&I fully cooperated with the agency. While WADA I&I cannot comment on the outcomes of the law enforcement investigation, it did not uncover evidence to substantiate the original allegations.

In line with WADA’s I&I policy, the findings of investigations are typically published. However, concerns regarding the safety of a source prompted WADA’s Executive Committee, during its meeting on 4 December 2024, to decide against publishing the full report. Instead, this summary has been released to maintain transparency while safeguarding the individuals involved.
