• Players will be punctual and polite, and at all times conduct themselves in a sporting manner.
• Verbal abuse towards an opponent, official or spectator is prohibited, including the use of foul language, before, during or after a match.
• Violent, threatening behaviour or bullying towards an opponent, official or spectator is prohibited. This includes any action which causes, or has the potential to cause, physical or mental harm to another person. For example deliberately throwing a bat or another object, or verbal threats made towards an opponent, breaking a ball, striking the table or any other equipment during play.
• A handshake will take place at the end of every match.
• Players must be particularly vigilant in their good conduct when playing against, or in the presence of, persons under the age of 18, and should always look to set a good example.
• Any disputes during a match will be referred to the umpire, or if applicable the tournament referee, for a final decision, with which all players will abide without argument.
• Observers will not involve themselves in said disputes (see 6. above).

Instructions for IDTTL Umpires

• If during a match the umpire considers a player to be in breach of the conduct rules, they should in the first instance warn the player that further poor behaviour will incur penalties. Example "Code Violation, use of bad language, warning"
  
• On the second and subsequent occasions, the umpire will award a point to the player's opponent. Example "Code Violation, abuse of bat, 1 point awarded to X."
  
• If at any time the umpire considers the offense to be significantly serious or repeated time and time again, they are to suspend that Set and report the event to either the Tournament Referee, or for league matches, the IDTTL committee by letter. If the Game involves a league match, remaining Sets should be completed, and the suspended Set awarded against the offender.
  For clarity, a Match is 10 sets, and each Set is the best of 5 Games.
  
• Umpires should be objective and impartial despite umpiring games involving their own team members.
• Umpires should not be drawn into arguments relating to a decision they have made (their decision is final).
• Objections to any umpire ruling may be made in writing to the IDTTL committee.

Examples of Poor Conduct

• Foul, abusive or offensive language or gestures
• Violent or threatening behaviour, either verbally, visually or physically
• Not accepting a ruling by umpire
• Abuse of equipment, ball, table, surrounds or other equipment (kicking walls, doors etc), damaging own bat.
• Delaying tactics (excessive toweling, toweling is only allowed every 6 points played)
• Excessive shouting, foot stamping.
• Coaching during a game.
• Accusing your opponent of cheating (issues should only be raised via the umpire)

Rules Reminder

• Coaching may not occur during Games. It is allowed between Games.
• The duration of rest between Games should not exceed 1 minute.
• Foul serving - the umpire shall warn the player in the first instance if there is doubt in its legality. Subsequent serving fouls will result in the point being awarded to the receiver. If there is no doubt in the first instance of an illegal serve, a point will be immediately awarded to the receiver. It is the responsibility of the player to serve so that the umpire can see that the service is legal.
• Calls of support and encouragement by observers BETWEEN (not during) points is allowed.
• Timeouts are not allowed.
