FOOLISH REFEREES AND HIGH SCHOOL RULES (WHICH I ABHOR)

PLEASE: NO MORE QUESTIONS ON HIGH SCHOOL RULES!!!
Question:

I watched a HS game last night in Wisconsin and Team A won in overtime and a number of the boys celebrated on the field by chasing the goal scorer as he ran towards his fans. A couple of them had removed their jerseys in celebration and the referee singled out one of them and yellow carded him for “unsportsmanlike”. This was his second yellow of the game so he also produced a red card. The ref literally chased him off the field to card him (after the game was over). Does the team have any recourse in terms of an appeal so that this player can play in the next game? What is the rule regarding carding a player after the game is over and the players are no longer on the field of play?

Answer (October 18, 2013):
As I consistently state in my answers (and the “About” section of the site), I do not answer questions regarding high school rules or referees. The rules are from another planet and some high school referees seem to have joined the migration.

Under the Laws of the Game, the rules the world plays by, the referee has no authority to punish players for purely technical offenses such as removing their shirts that occur AFTER the final whistle. (Look at all the international and professional games where this occurs on a regular basis.) Violent behavior or related actions, yes, but not removing the shirt. Please note, however, that if time had not actually run out when the disrobing and chasing occurred, then the referee was correct. On the other hand, if the game was truly over, then you should take this matter to the AD of the school for him or her to resolve.
