Michael Bisping and his ex-manager got into a scuffle outside a Manchester (U.K.) courtroom before a judge ordered the former UFC middleweight champion to pay more than $400,000 in unpaid commissions.

Bisping, 38, has been locked in a bitter dispute with his former rep, Wolfslair MMA Acadeny founder Anthony McGann, over his earnings from a management agreement signed in 2005, according to a report from the Manchester Evening News.

After an 11-day trial, Judge Richard Salter ruled Bisping owed McGann £320,000 – or approximately $426,313 – in back pay earned between 2005 and 2011.

Yet Salter chastised both of the former colleagues for their behavior during the proceeding, with Bisping “tailoring and trimming his evidence to suit his case,” calling the fighter’s recollection of Wolfslair “incredible and untrue” and “a confected story.” Salter called evidence of McGann’s previous business relationship with Bisping “recent fabrications” and “plainly untruthful.”

“Mr. Bisping was also a knowing participant with Mr. McGann in the scheme to defraud the Australian tax authorities by overstating Mr Bisping’s expenses in 2010 and 2011,” Salter said.

And, of course, the two allegedly got physical outside the court, which the judge said illustrated the “degree of ill-feeling” surrounding the case.

Bisping was not immediately reachable for comment, and his manager, Audie Attar, did not return a request for comment. McGann confirmed the ongoing trial, but declined to comment on the alleged “scuffle” and said he would release a formal statement shortly.

The next phase of the trial will determine who pays for the legal costs of the proceeding, which Salter said were “almost certainly out of all proportion to the sums at stake.” He added it would be “an affront to justice” to force Bisping to pay McGann’s fees.

Bisping (30-9 MMA, 20-9 UFC) is still on the mend after a first-round knockout loss to Kelvin Gastelum (14-3 MMA, 9-3 UFC) at UFC Fight Night 122, which denied him a quick turnaround from the loss of his middleweight belt this past month to the returning Georges St-Pierre (26-2 MMA, 20-2 UFC) at UFC 217.

Bisping has shrugged off retirement in hopes of getting one last octagon appearance at UFC Fight Night 127 in London.
