Competition Manual covers more. Personally, I think that this should be in the rule book since fewer people have the Comp. Manual than have the rule book.
3.3. Professional Misconduct
B. Players are expected to behave in a professional and sportsmanlike manner while participating in a PDGA sanctioned event. Actions that are in violation of this conduct include but are not limited to:
-Throwing items in anger (other than discs in play)
-Destruction or abuse of property, including plant life
-Cheating or willful attempt to circumvent the rules of play
-Fighting or threatening other players, tournament staff, or spectators
-Consumption of alcohol or use of any illegal substance from the 2-minute warning until the player's scorecard is submitted
-Abuse of alcohol after play and on course property is considered professional misconduct
C. The use of illegal substances is forbidden from the 2-minute warning until the player's scorecard is submitted. Such use shall result in immediate disqualification.
D. The use of alcohol is forbidden from the 2-minute warning until the player's scorecard is submitted. Such use shall result in immediate disqualification at a B Tier or higher event. At a C or D Tier event the TD shall either disqualify the offending player or issue them a warning. If a player has been issued a warning, all subsequent violations shall result in immediate disqualification.
E. Tournament Directors are to report any disqualifications to the PDGA as quickly as possible. Players who are guilty of any misconduct at the tournament site or any other facility associated with a PDGA sanctioned event may be subject to a fine and/or suspension from the PDGA. (Consult the PDGA Disciplinary Process for more information).
