Leyton Orient are attempting to halt West Ham United's proposed move into the Olympic Stadium by appealing to the High Court.
The football club in the third tier of English football, who have proposed a groundshare with the Hammers, have applied for a judicial review on the basis that the bidding process for the stadium's lease involving the Premier League club was "flawed".
Orient chairman Barry Hearn commented: "We believe that the bidding process is fundamentally flawed.
"The London Legacy Development Corporation have not followed their own rules when they set out the bidding process.
"All parties involved in the bidding process signed up to the principal of teaming and yet our bid has been turned down without consideration of teaming - eg. a ground-share with West Ham."
Meanwhile, Hammers co-owner David Gold claimed on Monday that his club are close to securing the ground.
