'Several months after a federal judge tossed a punished student’s anti-male discrimination claims against Princeton, the court has put the Ivy League university on the defensive.

U.S. District Judge Brian Martinotti refused to dismiss due process, breach-of-contract and good-faith claims under New Jersey law on Wednesday, citing a 3rd U.S. Circuit Court of Appeals decision from May on “fairness” in Title IX proceedings.

It was a reversal of fortune for “John Doe,” who failed to convince Martinotti in February that his federal Title IX claims were plausible. The judge also ordered the accused student to show why his court even had jurisdiction over John’s state-law claims.'
