The IOC has taken firm action in response to the findings of the McLaren Report on doping and manipulation in Russia, which showed that there was a fundamental attack on the integrity of the Olympic Games and on sport in general.

After establishing two Disciplinary Commissions in July 2016 – the Oswald Commission to investigate the alleged doping violations by Russian athletes at the Olympic Winter Games Sochi 2014, and the Schmid Commission to address the systematic manipulation of the anti-doping system in Russia - the IOC announced a series of decisions in December 2017. Read the press release and the full decision.

After 17 months of extensive work, the Schmid Commission confirmed "the systemic manipulation of the anti-doping rules and system in Russia, through the Disappearing Positive Methodology and during the Olympic Winter Games Sochi 2014, as well as the various levels of administrative, legal and contractual responsibility, resulting from the failure to respect the respective obligations of the various entities involved".

Read the final report from Schmid Commission

The IOC has re-analysed and is forensically examining all available urine samples collected from Russian athletes at the Olympic Winter Games Sochi 2014. All available blood samples collected from Russian athletes in Sochi have also been re-analysed.

The re-analysis led to a number of decisions by the Oswald Commission.
