Dwain Chambers is expected to make a return to the Olympics when the British athletics team is announced on Tuesday.
Chambers finished fourth in the 100 metres in Sydney in 2000, but has not featured in the Olympics since following his two-year suspension for systematic drug use and the imposition of the British Olympic Association's lifetime ban.
However, the BOA's ban was overturned by the Court of Arbitration for Sport earlier this year, clearing the 34-year-old to compete in a home Games which could well mark the end of his controversial career.
And despite not securing his place automatically, victory in the Olympic trials in Birmingham and his past record will prove enough for Chambers to gain selection.
Chambers initially wanted to chase the qualifying time required at the European Championships last week, but was given the option of not competing in the individual event in Helsinki as UK Athletics head coach Charles van Commenee felt it would take "something incredible" from his rivals to negate his case for selection.
Such performances never materialised, meaning Chambers will join teenager Adam Gemili in the 100m, with the final place likely to go to James Dasaolu.
"I got confirmation (in Helsinki) that it was the right decision not to run Chambers and Dasaolu because the ones we did run didn't do much," Van Commenee said.
Chambers could also be joined in the squad by another athlete previously barred due to a drugs ban, with Carl Myerscough impressing Van Commenee by achieving a second 'B' standard in the shot just hours before the deadline by seeking out a minor meeting in Estonia and catching a ferry from Helsinki to Tallinn late on Saturday night.
However, the selection of Chambers and Myerscough is unlikely to prove the most controversial aspect of selection, with Van Commenee bracing himself for a "heap of appeals" from desperate athletes.
"You can appeal on whether facts have been overlooked or the panel has not adhered to the policy as published," Van Commenee said. "So there is not much you can appeal against."
Any appeal must be lodged within 24 hours of the team announcement and then heard within 48 hours. The appeals panel consists of UKA chairman Ed Warner, UKA president Lyn Davies and an independent barrister.
By far the biggest cause for debate and possible appeals is the women's 800m, where Jenny Meadows, Marilyn Okoro, Emma Jackson, Jemma Simpson and Lynsey Sharp all hoped to be selected.
Sharp is certainly in the best form after her victory in the trials and silver medal in Helsinki, but she is also the only athlete without an 'A' qualifying time. Athletes with the 'B' standard can only be selected if no-one with the 'A' is chosen. In other words, picking Sharp means selecting no-one else.
Meadows, who has not raced once in 2012 but has the most impressive championship pedigree, said in Helsinki she would appeal if not selected.
