League One Leyton Orient chairman Barry Hearn is refusing to give up their fight over the Olympic Stadium tenancy.
In March, Premier League West Ham United were awarded the right to occupy the stadium from August 2016.
However, Hearn wants League One Orient to groundshare with the Hammers and is seeking a judicial review of the bidding process, reports BBC Sport.
"We're going nowhere. We've made our point and we've paid our lawyers," he told the club's website.
"The oral submission application has been put forward, now we're waiting for justice but don't expect any movement until September."
