Scoring
A goal is scored when an in-bounds player catches any legal pass in the end zone of attack, and retains possession of the disc throughout all ground contact related to the catch.
If after receiving a pass outside the end zone, a player comes to a stop contacting the end zone, that player must carry the disc back to, and put it into play at, the closest spot on the goal line.
If a player scores according to XI.A, but then unknowingly throws another pass, a goal is awarded to that player, regardless of the outcome of the pass. However, if it is unclear if the player scored according to XI.A (i.e., there is no agreement on the player who had best perspective, and there are opposing view points on the play), the result of the pass stands.
The act of scoring a goal is subject to rule II.O.2.
