Rules Analysis
The following actions result in a turnover and a stoppage of play:
i.e., this is not a "double-turnover" - the defender's team still gains possession.
The thrower catches a legally thrown disc. However, it is not a turnover if another player touches the disc during its flight unless the thrower intentionally deflected the disc off another player.
If a defender intentionally assists a teammate's movement to block or intercept a pass, the intended receiver is awarded possession at the spot on the playing field nearest the location the intended receiver occupied at the time of the infraction. If the intended receiver was in the end zone, 11.B and 11.C
The official interpretation of this rule is that a player is prohibited from intentionally pushing off of a teammate to jump higher
An offensive player uses an item of equipment to assist in catching a pass (e.g., throwing a hat or shirt at the disc). If a defender uses an item of equipment to assist in blocking or intercepting a pass, the intended receiver is awarded possession at the spot on the playing field nearest the location the intended receiver occupied at the time of the infraction. If the intended receiver was in the end zone, 11.B and 11.C apply.
