U2 have won back a Stetson hat and other items worn by Bono during the 1987 Joshua Tree Tour which had been taken by their former stylist.
The band had sued Lola Cashman, who attempted to put the Stetson, a pair of metal hooped earrings, a green sweatshirt and a pair of black trousers up for auction at Christie's in 2002.
At the Circuit Civil Court in Dublin, Judge Matthew Deery ordered Miss Cashman to return the items to the band within seven days.
He said he preferred the evidence of Bono, who told the court last week that he had not given her permission to take the items.
He noted in particular Ms Cashman's unlikely description of the final night of the Joshua Tree tour in Arizona in December 1987, when she said Bono had given her the Stetson hat while running around backstage in his underpants.
"It seems to me that Ms Cashman's version of events, the giving of the hat, is unlikely to have occurred," he said.
Neither U2, who are playing in Poland as part of their Vertigo tour, nor Ms Cashman were present in court for the judgment.
