Always make sure and call the head ref over to the mat. NEVER leave the mat if you are challenginf a call. I had a make a complete jerk of myself to get the head ref to come over on a terrible call. The head ref came over, sided with me and my son ended up winning the match. If I had left the mat, I would have not been able to get the decision overturned. if you are holding up a tournament over a call that you feel is wrong, then stand your ground. Refs will learn wich coaches watch them and what coaches they can get away with stuff on.
