Greg regularly referees soccer matches in his local association.

During one Saturday morning game Greg issues a red card to a player following what he considered to be a reckless tackle resulting in an injury to another player.

The coach of the player issued with the red card loudly questions the decision. A number of the team's supporters, encouraged by the coach's outburst, shout obscene comments at Greg.

One spectator is particularly aggressive and promises to take the matter up with Greg after the game.

Greg stops the match and asks the Club President of the home team to stop the sideline abuse.

The Club President warns the coach of breaching the code of conduct and formally notifies the aggressive spectator that he will face disciplinary proceedings for breaching the code of conduct two weeks in a row.

The aggressive spectator refuses to leave the ground but agrees to watch the remainder of the game away from the club rooms.

He is advised that any further threats to the referee would result in the police being called to attend the ground.
