17.5.1.

A Strip Foul occurs when a defensive foul causes the receiver or thrower to drop the disc after they have gained possession.

If an uncontested strip foul occurs where the offence causes the defence to drop a pass they have intercepted in the defences attacking end zone, this should be treated as a goal for the defence.

17.3.1.

A Strip Foul occurs when an opponent fouls a player and that causes the player to drop a disc they caught or to lose possession of the disc.

A player may not call a strip if they had only momentary contact with or lacked control of the disc prior to an opponent contacting the disc.If a defender hits the disc in flight before it is caught by the receiver, and that contact with the disc causes the receiver to drop the pass, that is not a strip. The defender is allowed to hit a disc in flight, when they hit a disc that has been caught by a receiver, that is when it can be treated as a strip foul.
