British insurer Lloyd's asked a Los Angeles judge to nullify a 17.5-million-U.S. dollar policy signed with Michael Jackson so that they won't have to pay for the late pop icon's canceled concerts, celebrity website TMZ.com reported on Monday.

In court papers filed with the Los Angeles Superior Court, Lloyd's said it shouldn't be forced to compensate for losses incurred by the canceled concerts, because Jackson's medical history was misrepresented to them.

The firm had insured Jackson's planned "This Is It" tour for losses. The proposed comeback concerts were canceled following Jackson's June 25, 2009 death.

Howard Weitzman, attorney for Jackson's estate, called the Lloyd's complaint "nothing more than an insurance company trying to avoid paying a legitimate claim by the insured."
