Rules Analysis
If an infraction is committed and not called, the player committing the infraction should inform the infracted player or team of the infraction.
It is the responsibility of all players to avoid any delay when starting, restarting, or continuing play. This includes standing over the disc or taking more time than reasonably necessary to put the disc into play.
This includes standing back from the disc, wandering around to gain more time, etc. Pretending not to delay while delaying is still delaying.
On a stoppage of play, if it is ever unclear which of a team's members are the current players or where they are on or off the field, they should identify themselves when the opposing team requests.
If a dispute arises on the field, play stops and is restarted with a check when the matter is resolved.
If a novice player commits an infraction out of sincere ignorance of the rules, it should be common practice to stop play and explain the infraction.
When a call is made, throwers 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 the marker has made reasonable efforts to notify the thrower of a call and believes that the thrower has not stopped play promptly enough, the marker may call a violation under this rule and a completed pass will come back to the thrower (17.C.4.a.1).
