The story, part of a long-running U.S. legal fight focused on the rights of the women, gained steam when Buckingham Palace took the unusual step of issuing a carefully worded denial of the kind of salacious claims that royal officials rarely acknowledge. Defense attorney Alan Dershowitz, who represented the highly connected Jeffrey Epstein and was himself named in the latest court filings, then called the most outspoken of the four women a serial liar and practically dared her to prove her accounts.

The concert promoter AEG was in no way responsible for Michael Jackson's death, a California court ruled Friday as it rejected an appeal brought by the singer's mother.
