List of tennis code violations

Under the Rules and Regulations of Tennis, when a player violates a rule or does not follow the tennis code of conduct, the umpire or tournament official can issue one of the following (Section IV, Article C, Item 18 – "Unsportsmanlike Conduct"):

"Point Penalty"
"Suspension Point"

Generally, this results in the following escalation:

First offense: Warning
Second offense: Loss of a point
Third (and each subsequent) offense: Loss of a game

After the third offense, it is up to the chair umpire (1%) but mostly tournament supervisor (99%) whether this constitutes a Default/Disqualification.

This is outside of any "off-court" issues related to a player's attire, behavior at media conferences, drug use, etc.
