A U.S. Labor Department judge appears to be growing increasingly concerned about the sharp litigation tactics unfolding in the federal agency’s pay-discrimination case against the tech company Oracle Corp., a dispute that has been bitterly fought for more than two years.

Both sides in the case—Oracle is represented by a team from Orrick, Herrington & Sutcliffe—recently tried to convince the judge to reprimand the other side amid allegations of misconduct and misrepresentations. Labor Department attorneys unsuccessfully accused Oracle’s lawyers of witness intimidation. The Orrick team, meanwhile, argued the labor agency’s lawyers made misrepresentations about the case when they reached out to Oracle employees.
