An appeals court Thursday overruled the finding of a state unemployment insurance appeal board that a man fired for getting into a fistfight with a co-worker at a Christmas Party in 2011 should be allowed to collect unemployment insurance benefits.

The appeal board had found that the anti-fighting policy of Nucor Steel Auburn did not apply to the time or place of the fight—a company party at a bar off working hours—and that Jeffrey Moniz’s behavior was not disqualifying misconduct under the meaning of unemployment insurance laws.
