Russian athletes who are not proven to be clean outside their countries own testing procedure have been banned from the forthcoming Olympic Games in Rio.
In a statement released on Thursday, the Court of Arbitration for Sport upheld the IAAF's decision to push through the suspension whilst a full-scale investigation is completed into an alleged state-sponsored program of doing.
The IAAF said the following: "The International Association of Athletics Federations (IAAF) has taken a strong stance on upholding the World Anti-Doping Code without fear and favour and is pleased that the Court of Arbitration for Sport (CAS) has supported its position.
"Today’s judgement has created a level playing field for athletes. The CAS award upholds the rights of the IAAF to use its rules for the protection of the sport, to protect clean athletes and support the credibility and integrity of competition.
IAAF President Sebastian Coe commented: “While we are thankful that our rules and our power to uphold our rules and the anti doping code have been supported, this is not a day for triumphant statements. I didn’t come into this sport to stop athletes from competing. It is our federation’s instinctive desire to include, not exclude. Beyond Rio the IAAF Taskforce will continue to work with Russia to establish a clean safe environment for its athletes so that its federation and team can return to international recognition and competition."
