Former drugs cheats Dwain Chambers and David Millar have been formally cleared to take part in the London 2012 Olympics.
The British Olympic Association have officially rescinded their lifetime ban for athletes found guilty of doping offences.
The move follows a Court of Arbitration for Sport ruling last month which declared the ban to be in contravention of the World Anti-Doping Agency (WADA) code.
It means Chambers can now be selected for Team GB's track and field team, and the same for Millar for the cycling road race team.
A BOA statement said: "Following a discussion period, during which members of the National Olympic Committee reiterated their support for the decision taken by the BOA board to defend the Eligibility Bye Law before CAS, it was agreed that the bye law would immediately be rescinded in order for the BOA to comply with the CAS ruling.
"The BOA will now notify WADA of this decision in writing.
"Additionally, the NOC encouraged the BOA to remain actively and constructively involved in the ongoing consultation process to amend the World Anti-Doping Code.
NOC members expressed a desire to see the Code amended in a manner that would provide stronger penalties for serious doping offences, and for the autonomy of National Olympic Committees in determining selection criteria for their Olympic Teams to not be undermined or subjugated as a result of the Code."
