Case related to Dwain Chambers became open door for other former steroid users to participate in Olympics

The sprinter Dwain Chambers, who successfully served his 2-year ban for administration of anabolic steroids, was chosen to be the representative of Great Britain in the 2012 London Olympics.
Chambers troubles about the way to represent the home country. When it comes to the British Olympic Association (BOA), they don’t want to see him taking part in the Olympic Games. Some former British Olympians don’t support the consumer of steroids as well.
The British sprinter administered the steroid tetrahydrogestrinone (THG) introduced by Patrick Arnold. After Don Catlin introduced a method that could discover intake of THG, Dwain Chambers tested positive for this steroid. It was on November 7, 2003.
Of course, administration of the steroid destroyed his reputation. When he attempted to come back to professional sports, the BOA made the decision to change the laws in order to prevent appearing of the sprinter in the 2012 Summer Olympics. The BOA has introduced the rules which suspend steroid users from Olympics for life-time.
Introducing this rule, the BOA violated the doping code of the World Anti-Doping Agency (WADA). This situation resulted in many disputes and news.
The case was even presented in the Court of Arbitration for Sports. The chairman of the BOA Loyd Moynihan put significant efforts in order to prevent appearing of Dwain Chambers or other steroid users at Olympics. Such former Olympians, as Sebastian Coe and Daley Thompson, loudly supported efforts of the BOA.
 Daley Thompson claimed that Britain should not compromise. He noted that Britain should not listen to the rest of the world that don’t desire to have high standards in sports. The Court of Arbitration for Sports acted on behalf of the WADA. Chambers was allowed to be the representative of Britain at the 2012 London Olympics. This case turned out to be an open door for other sportspersons that have served their bans to participate in Olympics.
The cyclist David Millar and the shot-putter Carl Myerscough that have served their suspensions for usage of steroids will compete at the 2012 Olympics too.
Despites spending much time to prevent appearing of steroid users at Olympic Games, the BOA finally confirmed that not only Chambers but also Millar, Myerscough or any other athlete that has served a suspension successfully may compete at Olympics. The CEO of the BOA Andy Hunt has confirmed that any athlete is treated the same way.
