A Birmingham man who was a founding member of boy band Busted has lost his claim over unpaid royalties at the High Court in London.
Owen Doyle, from Sheldon, and fellow former band member Ki McPhail, claimed they were owed an estimated £10 million in unpaid royalties.
But both were criticised by the judge as witnesses and have had their assets frozen before further hearings to decide who will bear the cost of the £1.7m trial, which was heard over 19 days.
The pair claimed they wrote songs with James Bourne and Matt Willis - including the hits Year 3000 and What I Go To School For - when the group formed in 2001.
They told the judge they were forced to sign away their rights after "threats" and "undue pressure" when they were sacked from the band later that year.
Doyle, who went to the Archbishop Ilsley School, in Acocks Green, was described by Mr Justice Morgan as "not a reliable witness".
The judge added: "He manifested a high degree of confusion and a failure to grasp the detail in relation to many of the significant events.
"Ki was not a reliable and convincing witness. He quite plainly exaggerated and distorted the real event.
"If he did believe the evidence he gave to the court, it can only be because he has indulged in very extensive self-serving reconstruction in the period between the relevant events and the time of the trial and has now convinced himself that his reconstructed version of events really happened."
None of the parties was in court today, but the claimants' representatives said they were considering an appeal.
McPhail and Doyle were in a band called The Termites with Bourne and Willis between January and October 2001.
They said they also wrote the songs Sleeping With The Light On and Psycho Girl together during their time with Busted, who had eight top 10 hits between 2002 and 2004 before splitting up a year later.
Andrew Forbes, of the solicitors who represented Busted, said Bourne and Willis "have emerged victorious".
"Doyle and McPhail were trying to claim a share of some of the band's biggest songs and also tried to use a partnership claim to grab a share of James' and Matt's income from all of Busted's activities.
"Doyle and McPhail pursued an aggressive strategy against James and Matt over the course of many years, both through the courts and by a concerted PR campaign.
"James and Matt believed that their claims were false and were motivated by jealousy of their success and sour grapes because Doyle and McPhail had failed to achieve any significant success themselves."
In a statement, the Busted pair said: "This was an opportunistic attempt by Doyle and McPhail to cash in on our success. Their claims were a complete fabrication and we are delighted that the judge has seen through this and totally dismissed them. Our position has been completely vindicated and our achievements with Busted remain untarnished."
Mr Justice Morgan said Kiley McPhail was also known as Kiley Fitzgerald because his father Scott McPhail, is professionally known as Scott Fitzgerald, the singer.
He said McPhail and Doyle disputed a written settlement under which they obtained the rights to two songs and Doyle and Bourne to four songs after the split.
McPhail and Doyle said the settlement should be set aside because they entered into it after "undue influence" by pop industry figures Richard Rashman and John McLaughlin.
The judge said it had been alleged that "there was a conspiracy to threaten Ki that if he stood up for himself the other side would take away his parents' house" in legal proceedings.
"In my judgment, the claimants' evidence on this point is another gross distortion of what really happened."
The judge found there never was a partnership agreement between the four parties involved and the claim by McPhail and Doyle failed.
