The U.S. Court of Appeals for the Second Circuit on Monday revived a lawsuit to recover $1.7 million in unpaid debt from Ohio-based drugmaker Navidea Biopharmaceuticals Inc., saying a district court judge had improperly dismissed the case without first determining a key jurisdictional issue.

The ruling, from a three-judge panel in an opinion by Judge Michael Park of the U.S. Court of Appeals for the Second Circuit, reinstated a 2017 suit filed by Navidea creditor Platinum-Montaur Life Sciences LLC and its Holland & Knight attorneys, claiming that the company was still owed the money under a 2012 loan agreement.
