We won't hear a result today but a discussion taking place inside an unremarkable building in London will have a dramatic impact on the make up of Team GB in London this summer.
The British Olympic Association (BOA) is fighting to keep its lifetime Olympic ban for drugs cheats in place - ironically the World Anti-Doping Agency (WADA), the organisation charged with catching the cheats, is arguing the law is too strict.
The BOA wants to maintain its right to pick who it wants for the team, WADA says drugs cheats already serve two year bans and banishing them into the Olympic wilderness is punishing someone twice for the same offence.
Britain is alone with its stance. If the BOA wins there will be the slightly curious sight of athletes from around the world, who've served bans for doping, competing freely while athletes from the UK, who are guilty of the same offence, are barred from doing so.
If the BOA loses the biggest winners will be Dwain Chambers and David Millar, the cyclist and those who argue that sport should mirror life so that everyone, no matter what they've done, deserves a second chance.
