The judge to make the call?

[BayStateRef]

The officials still have authority if a fight or other activity took place after the score is approved...but only under MIAA rules. The sanctions are strong -- game (or multiple game) suspensions for the participants.

The exact rule from the MIAA:

“Fighting and unsportsmanlike conduct penalties will be within the authority of the official at all times at the contest site. The official’s authority extends to pre and post game oversight.” Implementation of this rule could have future consequences on the offender, but does not affect the final score.

So, they're standing there with no authority, other than to contact the state governing body later on.
