Frank Warren has said he intends to sue the British Boxing Board of Control over its stance against those taking part in the fight between David Haye and Dereck Chisora.
The BBBoC is threatening to revoke the license of any of party involved in the July 14 domestic clash.
Warren insists there is nothing wrong with the fight and if forced he will take action to that effect.
"I intend to issue proceedings," Warren said. ""I will support all other licence holders who feel intimidated into not participating in the Haye v Chisora promotion."
"The board seems to have pre-judged the issue without hearing the point of view of any of its members and this is just wrong."
Warren also expressed his disappointment that the board's stance looks set to prevent Kevin Mitchell from fighting on the Upton Park undercard in front of his hometown fans.
He said: "This is such a shame as Kevin was looking forward to fighting in front of the crowd at West Ham and it would have been great for the fans to see him again.
"He is asking the board to reconsider and it may be forced to do so rather than face proceedings from Kevin for the purse he would have earned together with the lost opportunity to fight in front of 40,000 people."
It seems the legal implications of the all-British heavyweight clash may rumble on long after the last punch is thrown on July 14.
