Dwain Chambers will be allowed to compete at the London 2012 Olympics, according to reports.
The Daily Mail this morning claim the British Olympic Association (BOA) have admitted defeat in their battle to prevent the sprinter from commencing at this summer's Games.
A verdict on Chambers' fate will be delivered by the Court of Arbitration for Sport (CAS) next week, possibly as early as Monday.
Chambers, 33, previously tried to challenge the by-law through the High Court prior to the 2008 Beijing Olympics, but didn't succeed.
The disgraced sprinter failed an out-of-competition drug test in 2003, and subsequently admitted to the use of performance enhancing substances, which saw him banned from athletics for two years and from the Olympic Games for life.
Lawyer Howard Jacobs however said as early as February he was convinced Chambers would be afforded the opportunity to compete in London.
Jacobs previously helped American runner LaShawn Merritt overturn his Olympic doping ban, and said two months ago: "When I heard the BOA's response to the Cas decision, what they were saying sounded a lot like what the International Olympic Committee were saying, trying to characterise the rule as an eligibility rule as opposed to a sanction.
Merritt won two golds at Beijing in the 400 metres and 4x400m relay but in 2010 tested positive for a banned steroid, after he failed three tests, and was handed a two-year suspension.
That was later reduced to 21 months in early 2010, but Merritt argued it went beyond Wada sanctions of a maximum two-year ban.
Cas then heard the appeal and judged that the IOC's rule was illegitimate as it amounted to an additional sanction.
Cyclist David Millar, banned for two years in 2004 after he used the blood-boosting agent EPO, could also be allowed to feature - taking the tally of drug cheats at London 2012 to an estimated 80 competitors.
