The Court of Arbitration for Sport will announce their decision over the British Olympic Association's lifetime doping ban on Monday.
The BOA hopes that such a ban will be allowed to stand, while the World Anti-Doping Agency are looking to overturn the bylaw in favour of a standard two-year ban for athletes.
Both sides argued their cases at a hearing held back in March.
If the BOA lose, as expected, athletes such as Dwain Chambers would be allowed to compete at this summer's London Games.
