Hearn is proposing a ground share with West Ham and he is relying on the courts to rule in his favour.
West Ham are expected to be confirmed as the new tenants of the Stadium on Thursday.
"Obviously we have applied to the High Court for a judicial review of the bidding process, they may well announce that West Ham are going into the stadium but it would have to be subject to the judicial review," he told Sky Sports.
Hearn hopes that the decision on the judicial review will arrive before the summer.
"It is a question of weeks rather than months," he said.
"We think our case is straightforward, we see it is cast iron and let us see if the judges agree and if they do then all bets are off and we will have to sit down and start talking again.
"This is a long running process and I do apologise for the delay but until they get it right I am not going to sit down and let someone steamroller my little football club.
"We are suggesting a ground share with West Ham but we are not getting much support...so we are fighting our corner as we do from the East End."
