Rules of Ultimate governed by the World Flying Disc Federation

15. Calling Fouls, Infractions and Violations

  1. 15.1. A breach of the rules due to non-incidental contact between two or more opposing players is a foul.
  2. 15.2. A breach of the rules regarding a Marking or Travel breach is an infraction.  Infractions do not stop play.
  3. 15.3. Every other breach of the rules is a violation.
  4. 15.4. Only the player fouled may claim a foul, by calling “Foul”.
  5. 15.5. Only the thrower may claim a marking infraction, by calling the specific name of the infraction. Any opposing player may claim a travel infraction.
  6. 15.6. Any opposing player may claim a violation, by calling the specific name of the violation or "Violation", unless specified otherwise by the particular rule.
  7. 15.7. When a foul or violation call is made that stops play, players must stop play by visibly or audibly communicating the stoppage as soon as they are aware of the call and all players should echo calls on the field. If play has stopped for a discussion without any call having been made, a call is deemed to have been made when the discussion started.
  8. 15.8. Calls must be made immediately after the breach is recognised.
  9. 15.9. After a player initiates a stoppage incorrectly, including after mishearing a call, not knowing the rules, or not making the call immediately:
  10. 15.9.1. if the opposition gains or retains possession, any subsequent play stands.
  11. 15.9.2. if the opposition does not gain or retain possession, the disc must be returned to the last non-disputed thrower.
  12. 15.10. If the player against whom the foul, infraction or violation has been called disagrees that it occurred, they may call “Contest”.
  13. 15.11. If a player making the “Foul”, “Violation” or “Contest” call subsequently determines that their call was incorrect, they can retract the call, by calling "Retracted".  Play restarts with a check.
