A federal judge has declined to dismiss all claims brought by an art authentication expert who insists he was libeled in a July 2010 article in The New Yorker.

While Southern District Judge J. Paul Oetken rejected the majority of claims filed by art authenticator Peter Paul Biro against writer David Grann and Conde Nast, which publishes the magazine, he ruled that Biro could plausibly argue that some of the statements in the piece were libelous.
