The High Court said today it would decide at a later date whether a former U2 stylist would be allowed to keep souvenirs from the rock group, including a pair of Bono 's trousers and his Stetson hat.
U2 sued Lola Cashman last year for the return of mementos she said had been given as presents when she worked with them in the 1980s.
Cashman was ordered to return the items, which included a Stetson hat, a pair of black trousers, and earrings Bono wore during the band's 1987 Joshua Tree tour, but she appealed and this week went to court in a bid to overturn the ruling.
In a judgment last year Judge Matthew Deery described as "unlikely" Cashman's claim that the items were gifts, and accepted there was a strict protocol in relation to the archiving of the band's working wardrobe.
Bono told the court at the time he would not have given Cashman the items, which he said had iconic status. Cashman, who published an unauthorised biography of the band entitled Inside the Zoo with U2, had attempted unsuccessfully to sell the memorabilia at an auction in 2002.
Also among the disputed items were 200 Polaroid photographs Cashman took of the band, and a Christmas decoration.
