Caster Semenya awarded gold for 800m at 2012 London Games

The Court of Arbitration for Sport said in a statement Friday that the Russian champion middle-distance runner, identified as Mariya Savinova-Farnosova, was found to be involved in doping from July 26, 2010, through August 19, 2013.

The latest blow to Russia's sporting image should give South African Caster Semenya the 2012 Olympic title to add to the one she claimed in Rio past year.

Mariya Savinova has been banned from athletics until 2019 after she was found guilty of doping for over three years.

Savinova-Farnosova was one of five athletes who WADA recommended lifetime bans for back in November 2015.

Savinova won the race in a world-leading time of 1:56.19, beating the South African favourite into second place.

What do Analysts suggest for: Activision Blizzard, Inc. (NASDAQ:ATVI)
The stock is getting much attention these days as insiders are offloading shares while they posted a 8.53% rise year to date. California State Teachers Retirement System increased its stake in Activision Blizzard by 7.6% in the second quarter.

Russian doping whistleblower Yulia Stepanova secretly filmed Savinova appearing to admit taking the banned steroid oxandrolone. "If CAS decided (to ban Savinova) nothing can be done", he told Russia's Tass news agency.

The ruling also means Osaka 2007 world champion, Janeth Jepkosgei will also be upgraded to Daegu 2011 silver after the same Russian athlete beat the Kenyan and South Africa's Caster Semenya to the top medal. Savinova was also stripped of the prizes and medals won between July 2010 and August 2013.

CAS, in its statement, explained that it was acting as the "first instance decision-making authority for this matter" since the Russian Athletics Federation (RusAF) is suspended and was not available to adjudicate the case.

The country's athletes missed last year's Rio Olympics and will be absent at August's World Championships in London after the IAAF voted to extend Russia's suspension.
