Britain’s former drugs cheats can compete at London 2012 after a court overturned the British Olympic Association’s policy of lifetime bans.
The BOA lost its battle with the World Anti-Doping Agency (Wada) at the Court of Arbitration for Sport (Cas).
It means sprinter Dwain Chambers, 34, and cyclist David Millar, 35, can try to qualify for Team GB.
“The by-law is a doping sanction and therefore not in compliance with the Wada Code,” Cas said.
The BOA had been locked into a lengthy legal battle with Wada over what it said was its right to continue imposing lifetime Olympic bans on British athletes, even after they had served suspensions.
In November, Wada ruled this BOA by-law was not compliant with the Wada code, prompting the BOA to appeal against the decision at Cas.
But Cas has ruled the BOA must comply with Wada, paving the way for British athletes who were banned for life from Olympic competition to be eligible for selection after serving shorter bans.
BOA chairman Lord Moynihan told a news conference: “The BOA are clearly very disappointed in the outcome.
“We must now move the discussion forward. We will seek far-reaching reform, calling for tougher and more realistic sanctions; a minimum of four years including one Games.”
The BOA argued that its requirement for athletes to have clean drugs records was part of its Olympic selection criteria and had nothing to do with extending violators’ punishments – a view supported by a number of high-profile current British athletes and the International Olympic Committee (IOC).
Following the ruling, Chambers’ lawyer Siza Agha said the BOA had been “crude and defiant” in its determination not to comply with Wada.
Agha said: “In my view, as hosts for the 2012 Olympics, this delicate and emotive issue required international diplomacy, foresight and responsibility.
“What we have received has been a crude and defiant display fuelled by misguided statements such as ‘we have standards and the rest of the world doesn’t’.
“It has, in my view, been an exposure of colonial arrogance that even the most extreme and blinkered should have realised could only serve to marginalise British opinion on the international stage.”
Athletes will still have to reach the Olympic qualifying standard to be considered for selection.
A spokesperson for British Cycling said after the ruling: “Our team for the Games is being selected in June and, across all disciplines, we’ll pick the team based on which riders are fit and available, and who we believe have the best chance to deliver medals. Ahead of that we won’t be speculating on who may or may not be selected.”
