Billionaire uncorks new lawsuit over rare wine

NEW YORK – A billionaire collector and yachtsman has uncorked another lawsuit in his 4-year-old battle against fraud in the rare wine business.

William Koch (KOHK) sued the auction house Christie's International in New York on Tuesday. He claims it ignored evidence of fakery in the 1980s when it marketed several bottles that were supposedly once owned by Thomas Jefferson.

The suit is the latest in a string filed by Koch over the collection, now regarded by some experts to have been counterfeit.

Christie's denied the charges, which it called "incorrect."
