Leyton Orient chairman Barry Hearn says that he will have to wait until the autumn before the case for the Olympic Stadium will be heard.
Premier League side West Ham were named the preferred bidders to adapt and move into the stadium but the League One club's chief believes that the London Legacy Development Corporation's (LLDC) rules were not followed.
On learning of the Hammers' victory back in March, Hearn asked the High Court for a judicial review but it is likely that this will not be heard until at least September.
Hearn told the club's official website: "Obviously the oral submission application (for judicial review) has been put forward to the courts but, the way the courts and the traditional system is working, I think it will probably be September before that case is heard
"But we're not going anywhere. We've made our point and we've paid our lawyers and we're waiting for justice, so let’s hope we get it in September."
Plans are already in place to adapt the stadium in time for the 2015 Rugby World Cup, with the Hammers set to move into the stadium the following season.
