In 2003, sprinter Dwain Chambers was caught taking the banned steroid THG. He served a two-year ban, and has now turned informer to the anti-doping authorities and returned to the track. Earlier this week he ran the fastest 100m by a British athlete this year, and he intends to win a place on the British Olympic team at the trials just over a week from now. He looks to have a great chance.

The problem is that the British Olympic Association (BOA) has a policy of not selecting athletes that have failed drug tests, whether they’ve served their bans or not. No matter how well Chambers does in the trials, the BOA won’t pick him unless they’re forced to.

Chambers will challenge the legality of this policy in court, arguing that it constitutes an illegal restraint of trade. He hopes to get a ruling from the court saying that the BOA have to pick him if he does well enough at the trials.

In response to Chambers’ challenge, the British Athletes’ Commission (BAC) has taken up a petition calling for the selection policy to stay in place. Over a hundred athletes have signed, including big names such as Steve Redgrave and Kelly Holmes. The BAC’s Peter Gardner explained, “The petition carries weight because it has support from many athletes.”

He’s wrong. The petition doesn’t carry much weight at all.

The question here concerns a point of law: Does the BOA’s policy of not selecting athletes that have failed drug tests constitute an illegal restraint of trade? The petition only tells us that certain people approve of the BOA policy; it doesn’t tell us anything about whether it is legal or not. The policy may be popular, perhaps even have near unanimous support among athletes, but still break the law. This appeal to popularity shouldn’t persuade the court.

The presence of big names on the list doesn’t change this. Holmes and Redgrave have plenty of Olympic gold medals between them, but being a faster runner or rower than anyone else doesn’t give you much insight into employment law. To suggest that Chambers’ ban should be upheld because some great British Olympians say so would be an inappropriate appeal to authority.

I sympathise with the athletes that have signed the petition: I hope that the selection policy is legal and can be maintained. But the petition itself isn’t evidence that should sway the court.
