Rules Analysis
A turnover that transfers possession of the disc from one team to the other, and results in a stoppage of play, occurs when:
If a player determines a turnover has occurred they must make the appropriate call immediately. If the opposition disagrees they may call "contest". If, after discussion, players cannot agree or it is unclear what occurred in the play, the disc must be returned to the last non-disputed thrower.
If a fast count occurs in such a manner that the offence does not have a reasonable opportunity to call fast count before a stall-out, the play is treated as a contested stall-out (9.5.3).
Any offensive player may take possession of the disc after a turnover, except:
If, in attempting to intercept a pass, a defender from Team A loses control of the disc due to ground contact, or accidentally drops the disc, then the catch is deemed to have not occurred and any player on Team A may take possession of the disc.
If the player in possession after a turnover intentionally drops the disc, or places the disc on the ground, they must re-establish possession and restart play with a check.
What:
Player A intercepts a pass and then intentionally drops the disc, or places the disc on the ground to allow their teammate to become the thrower.
Player A retrieves an out-of-bounds disc and then intentionally drops the disc at the location of the intended pivot to allow their teammate to become the thrower.
Result:
This is not a "double turnover". The opposition can call a Violation in which case play stops and Player A must take possession of the disc. Play must restart with a check.
Extra:
If Player A attempts a pass directly after the interception, and this pass is incomplete, this is a turnover.
Note:
If there is any uncertainty as to whether the players' loss of possession was due to attempting to allow a teammate to become the thrower, or that they were in fact attempting a pass that was incomplete, the player should be given the benefit of the doubt.
If the turnover location is out-of-bounds, or the disc touched an out-of-bounds area after the turnover occurred, the thrower must establish a pivot at the spot on the central zone nearest to where the disc went out-of-bounds (Section 11.7).
Note:
The official spot is just next to the line (since the line is not part of the playing field), but a pivot foot on the line is also acceptable. Given the fact that perimeter lines are only a few centimetres wide, the "error" is too small to be significant. While the rules state that the pivot point should be established in-bounds, rule 11.3.2 also says that it is not a problem that the pivot foot contacts an out-of-bounds area. Extra: If the disc flew out the side of the end zone, there is a cone on the spot where the pivot point should be established. Rule 2.6 states that the edge of the central zone must be marked by that cone, so the player should not move it. Therefore the pivot point should be established on the end zone line next to the cone. Players should not move the cone. Note that the player is allowed to have enough room to turn on their pivot foot (otherwise unsafe situations might occur during pivoting).
If the turnover location is in the central zone, the thrower must establish the pivot at that point.
The pivot should be as close to the disc's location as possible. Players should not place their right foot at the turnover location and then use their left foot as their pivot. This is a travel infraction (18.2.5.1).
If the turnover location is in the offence's attacking end zone, the thrower must establish the pivot at the nearest point on the goal line.
