REFEREE CANNOT CHANGE A DECISION ONCE THE MATCH HAS BEEN ENDED

Question:
My 15 yr. old son was involved in a physical altercation during a soccer game with 5 seconds left in the game.

The altercation involved 2 of our players and 3 players from the opposing team. One of our players and one of the opposing players were each given a red card and ejected from the game. The Referee gave my son a yellow card and he was allowed to play out the remaining 5 seconds of the game.

After the game had ended, the referee and 2 linesmen gathered at centre field. About 5 minutes after the game had ended, the referee walked over to my son (where he was sitting on the team bench getting changed) and proceeded to give him a red card without explanation. There was no further incident nor foul language or anything that prompted the yellow card being increased to a red card. I believe perhaps one of the linesmen convinced the ref after the game had ended that my son was deserving of a red card for his participation in the initial altercation that resulted in 1 player from both teams being red carded and ejected from the game.

Can a referee change a yellow card to a red card after the player has been allowed to continue playing in a game and/or after the game is over and the player has left the field for the day and without further incident?

Answer (July 24, 2014):
Major referee error, Dad. Once the game has been ended, the referee may not change any decisions made prior to the final stoppage. This wording from Law 5 (The Referee) confirms that:

Decisions of the referee
The decisions of the referee regarding facts connected with play, including whether or not a goal is scored and the result of the match, are final.

The referee may only change a decision on realising that it is incorrect or, at his discretion, on the advice of an assistant referee or the fourth official, provided that he has not restarted play or terminated the match.

Your son has the right of appeal against this decision and the referee should be sent back for further training—along with whichever assistant referee recommended changing the original decision.
