BOA changed laws in order to keep Dwain Chambers out of Olympics

The runner Dwain Chambers, that successfully served his 2-year ban for usage of anabolic steroids, was named the representative of Great Britain in the 2012 Olympics.
Chambers worries about the way to represent the home country. As for the British Olympic Association (BOA), they don’t want to see him participating in the 2012 Summer Olympics. Several former British Olympians don’t support the consumer of steroids as well.
Dwain Chambers applied the steroid tetrahydrogestrinone (THG) elaborated by Patrick Arnold. After Don Catlin developed a method which could disclose administration of THG, the sprinter tested positive for this steroid. It was on November 7, 2003.
Of course, application of the steroid destroyed his reputation. When he attempted to return to professional sports, the BOA made the decision to change the laws in order to prevent appearing of Dwain Chambers in the 2012 Olympics. The BOA has established the rules that ban steroid users from Olympics for the whole life.
Establishing this rule, the BOA violated the doping code of the World Anti-Doping Agency (WADA). This factor led to many disputes and news.
The case was even examined 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 consumers of steroids at Olympics. Sebastian Coe and Daley Thompson, former Olympians, loudly supported efforts of the BOA.
 Daley Thompson wrote that Britain should not compromise. He claimed that Britain should not listen to the rest of the world that don’t want to have high standards in sports. The Court of Arbitration for Sports acted on behalf of the WADA. Dwain 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 athletes 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 administration of steroids will compete at the 2012 London Olympics too.
Despites spending much time to prevent appearing of steroid users at Olympics, the BOA finally confirmed that not only the sprinter Dwain chambers but also Millar, Myerscough or any other athlete that has served a suspension successfully may compete at Olympic Games. The CEO of the BOA Andy Hunt has claimed that any athlete is treated the same way.
