Yes, there are certain things that negate AOE/COE determination. Horseplay, coming-and-going (i.e., on the way to or from work), and instigating a fight are three of them; if the injury is as a result of the employee’s intoxication is another, though that’s difficult to prove as we must show that the accident would definitely not have happened if the claimant weren’t under the influence. There are a few more, but I don’t recall them off the top of my head.
