Rules Analysis
If multiple infractions occur on the same play or before play stops, the outcomes should be resolved in reverse sequence (latest infraction first, earliest infraction last).
If an earlier infraction is determined not to have affected the play (17.C.1 and 17.C.5), that infraction is not resolved and it does not affect the resolution of subsequent infractions.
Not resolved essentially means that the call is treated as if it had not occurred and the result of the play (possession, stall count, etc.) is unchanged by that call.
Offsetting infractions: If both offensive and defensive infractions occur simultaneously or the sequence cannot be determined, the resolution for this set of infractions is: the disc is returned to the thrower and put into play with a check, with the count reached plus one or at six if over five.
It is possible that resolutions to earlier infractions may ultimately change this particular outcome.
Examples
- A receiver and their opponent contact each other and both call fouls against the other. 17.H.2 applies, and the disc is returned to the thrower and put into play with a check, with the count reached plus one or at six if over five. - Two different receiver-opponent pairs call fouls -- one against the offense and one against the defense -- while the disc is in the air, but before anyone starts trying to catch it. 17.H.3 applies in this case, even if the fouls occur several seconds apart. The disc is returned to the thrower and put into play with a check, with the count reached plus one or at six if over five. - The marker calls an offensive foul on the thrower during the throw, then later a receiver calls a defensive foul on a defender during the reception on an incomplete pass. The fouls are resolved in reverse sequence. First, the receiving foul is resolved (here, assumed uncontested), granting possession to the offensive receiver, then the throwing foul is resolved (here, assumed uncontested), returning the disc to the thrower with the count reached plus one (max nine). The earlier infraction (offensive foul on the thrower) takes precedence over the later infraction (defensive foul on the receiver), resulting in the disc returning to the original thrower.
