U2 (search) launched a lawsuit Tuesday against one of its former stylists, Lola Cashman (search), who has a range of memorabilia from her work on the band's 1987 "Joshua Tree" world tour (search).

In 2002 Cashman tried to sell some of the items — including a Stetson cowboy hat, sweatshirt, trousers and earrings worn by Bono during the tour — at the Christies auction house in London, but at that time U2's lawyers stopped the sale by telling the auctioneers that the goods weren't hers to sell.

On Tuesday one of U2's lawyers, Paul Sreenan, told Dublin Circuit Court judge Matthew Deery that Bono and other U2 members would testify that they had not given any of the items to Cashman, who was also accused of claiming inappropriate expenses during the 1987 tour.

Sreenan said the band hoped the judge would issue a judgment that Cashman should not continue to possess or try to sell any of the materials in dispute, including about 200 photos of the 1987 tour.

None of the U2 members was in court Tuesday. The band completed a three-night concert stand Monday night in their hometown with an 80,000-seat sellout performance at the city's Croke Park stadium.
