DOVER, Del. AP – The state Supreme Court has upheld the dismissal of lawsuit filed by a Delaware couple who claimed they were defrauded when they bought a forged painting at a Christie’s auction.

Johannes and Betty Krahmer appealed to the Supreme Court last year after a Chancery Court judge dismissed their 2004 lawsuit against Christie’s, saying the lawsuit was filed too late, and that there was no evidence to infer that the famed auction house knew the painting was a fake.
