False. According to the rules of Ultimate, a player cannot call a violation as per rule 10.7 if a player on their own team, including themselves, is in the wrong position or is moving before the check. This is explicitly stated in the rules, indicating that such a situation does not warrant a violation call by a teammate.

True. According to the rules of Ultimate, if a defensive receiving foul is called and the call is contested, the disc is indeed returned to the thrower. Additionally, the players involved in the foul must return to their positions at the time of the throw, as specified in the rules. This ensures that the situation is reset to the state before the foul occurred, allowing for a fair continuation of play.

False. According to the rules of Ultimate, if the thrower has possession of the disc and a stoppage has occurred, the defender does not need to call "Disc In" to restart play if the disc is not within reach. The rule that requires the defender nearest to the disc to call "Disc In" specifically applies when the disc is on the ground, not when it is in the possession of the thrower. Therefore, in the scenario described, the play would not be restarted by the defender calling "Disc In."

In the scenario described, where a stoppage has occurred and the thrower has possession but the disc is not within reach of a defender, the rules specify that the defender nearest to the disc must call "Disc In" to restart play. This is in accordance with the rules of Ultimate which state that when the disc is on the ground, the defender nearest to the disc must call "Disc In" to initiate the continuation of the game.

False. According to the rules of Ultimate, if the marker recognizes that the thrower has established a pivot at the incorrect spot, they cannot wait until the stall count gets to 6 or until a pass is made before they call a travel. The marker should call the travel as soon as they recognize the infraction. If a player had a reasonable opportunity to recognize that a breach had occurred but continued play as if no breach had occurred, they should not make the call later on. Therefore, the marker should call the travel immediately upon noticing the incorrect pivot, not after a pass is made.

True. According to the rules of Ultimate, players must establish a stationary position during stoppages of play, which is when play is considered 'dead'. For example, during a time-out, all offensive players must establish a stationary position at any location, as per the Time-Outs rule (20.3.3). Similarly, defensive players must also establish a stationary position at any location once the offensive players have selected positions (20.3.4). Additionally, after a call is made and play stops, all players must return to the location they held when the call was made and remain stationary until the disc is checked in (10.2.2.3). Therefore, it is accurate to say that players must be stationary anytime that play is 'dead'.

False. According to the rules of Ultimate, when the thrower has the disc and there is a defender within reach, the defender must touch the disc, but it is not explicitly stated that they must say "Disc In." The defender is required to touch the disc to check it in, and the defense must actively choose to touch the disc – the thrower cannot initiate the check by tapping the disc against the defender. However, if the disc is on the ground, the defender nearest to the disc must call "Disc In."

False. According to the rules, after a travel violation where the thrower incorrectly establishes a pivot point on the side of the end zone instead of at the goal line, the thrower must return to the location occupied at the time of the infraction, which is on the sideline. The disc must be returned to the thrower and checked in where the infraction occurred, on the sideline. Once the disc is checked in, the thrower must then move to the goal line to establish the correct pivot point. All other players may move once the disc is checked in, and the disc is considered dead until the pivot is established at the correct spot on the goal line. Therefore, the thrower and marker do not both move to the correct pivot location on the goal line before the disc is checked in. The thrower first checks the disc in at the sideline, where the infraction occurred, and only after the disc is checked in do they move to establish the pivot at the goal line.

True. According to the rules of Ultimate, when the thrower has the disc and there is a defender within reach, the defender must touch the disc to restart play. This is known as "the check."

False. According to the rules of Ultimate, a player cannot call a violation as per rule 10.7 because a player on their own team (including themselves) is in the wrong position, or is moving before the check. Therefore, a player may not call a violation regarding the check if their teammate was not in the appropriate position.

True. According to the rules of Ultimate, when the thrower has the disc and there is a defender within reach, the defender must touch the disc to restart play. This is outlined in the rules under "The Check" (10.6.1).

False. According to the rules of Ultimate, when the disc is on the ground, it is the defender nearest to the disc who must call "Disc In" to restart play, not the offensive player. This is specified in the rules under "The Check" (10.6.1.2).

False. According to the rules of Ultimate, the perimeter lines are not part of the playing field. They surround the playing field and consist of two sidelines along the length and two endlines along the width, but they themselves are considered out-of-bounds.

The statement "The perimeter lines are part of the playing field" is incorrect according to the rules of Ultimate. Specifically, the perimeter lines, which consist of two sidelines along the length and two endlines along the width of the playing field, are not part of the playing field itself. This is clarified in the rules, which state that the entire playing field is in-bounds, but the perimeter lines are out-of-bounds. Therefore, the perimeter lines surround the playing field but are not included within it.

False. According to the rules of Ultimate, when a violation is called, if the thrower does not hear the call and makes a pass, the play is stopped and the disc is returned to the thrower. However, players must return to the location they were in when the call was made, not when the pass was thrown. This is outlined in the rules stating that if play stops before a pass is thrown, all players must return to the location they held when the call was made.

True, this is a travel infraction. According to the rules of Ultimate, the thrower may not begin a wind-up or other part of the throwing motion until they have established a pivot point. In the scenario described, the thrower winds up for a throw while running to the pivot location, which is not allowed. The pivot must be established at the correct position before the thrower can initiate a throwing motion. If the thrower does this before establishing the pivot, it is considered a travel infraction.

False. According to the rules of Ultimate, a thrower must establish a pivot point, which is a specific point on the ground with which one part of their body remains in constant contact until the disc is thrown. The pivot point is determined when the thrower establishes it, not when they pivot. The thrower may not begin a wind-up or other part of the throwing motion until they have established a pivot point. If the thrower establishes a pivot point at an incorrect location, it is considered a travel infraction. Therefore, the pivot point is determined when the thrower establishes it, not when they pivot.

When a defensive receiving foul is called and the call is contested, the disc is indeed returned to the thrower to restart play. According to the rules, all players must return to their respective positions at the time of the throw, not when play stopped. This is to reset the play to the conditions that existed before the contested foul occurred. Please note that if the foul had been uncontested, the receiver would have retained possession. However, since the foul is contested, the disc goes back to the thrower, and players must reset their positions accordingly.

Based on the rules of Ultimate, if the thrower from Team A releases the disc and then taps it to avoid an interception by Team B, and the disc subsequently hits the ground, this would result in a turnover. Since the thrower is the last person from Team A to have contact with the disc before it hits the ground, possession would transfer to Team B. The result of the play stands as described, with Team B gaining possession where the disc hit the ground.

False. According to the rules, if a defensive receiving foul is called and the call is contested, the disc is indeed returned to the thrower. However, the players do not stay where they were when the foul occurred. Instead, they should return to the positions they occupied at the time of the throw, as per the general principle of returning to the last non-disputed position when a call is contested. This is to reset the play to the situation before the contested foul occurred.

True. According to the rules of Ultimate, to restart play when the thrower has the disc and there is a defender within reach, the defender must touch the disc as stated in 10.6.1.

False. According to the rules, if there is a defender within reach, the defender must touch the disc to restart play. However, if the disc is not within reach of a defender, the defender does not need to call "Disc In" to restart play. Instead, the thrower can simply re-establish possession and play can continue.

False. According to the rules, after Team B gives a warning for an unnecessary delay, they may check the disc in by calling "Disc In" without verification from the opposition if the delay continues. However, this can only be done if the team checking the disc in (Team B in this case) are all stationary and positioned as per the rules. If members of Team B are still moving, they cannot check the disc in.

False. According to the rules of Ultimate, the perimeter lines are not part of the playing field. They surround the playing field and consist of two sidelines along the length and two endlines along the width, but they themselves are considered out-of-bounds (source_reference 2.2 and 2.1).

False. To restart play when the thrower has the disc and there is a defender within reach, it is not enough for the defender to just touch the disc and say ‘Disc In’. According to the rules, the defender must touch the disc, but there is a recommended sequence of steps that should be undertaken before checking the disc in, which includes asking if the offense and defense are ready, announcing the stall count, and then touching the disc, touching the disc to the ground, or saying ‘Disc In’, as appropriate. The defense must actively choose to touch the disc – the thrower cannot initiate the check by tapping the disc against the defender. Therefore, simply touching the disc and saying ‘Disc In’ does not fully comply with the recommended procedure for restarting play.

False. According to the rules of Ultimate, after a turnover, the marker cannot start the stall count until the thrower has established a pivot. If the offensive player is simply standing over the disc and has not yet established a pivot, the marker must wait before starting the stall count. This is to ensure that the thrower is given the opportunity to establish a pivot point and is ready to play before the defense can begin counting.

False. According to the rules of Ultimate, after a turnover, the marker cannot start the stall count until the thrower has established a pivot. Specifically, Rule 14.1 states that a check is not required after a turnover, but the thrower can only make a pass, and the marker can only start the stall count, once the pivot is established at the correct position. If the marker starts the stall count before the pivot is established, this is considered a fast count infraction. Therefore, if an offensive player is simply standing over the disc after a turnover, the marker must wait until the thrower has established a pivot before starting the stall count.

False. According to the rules of Ultimate, after a turnover, the marker cannot start the stall count until the thrower has established a pivot. If the offensive player is simply standing over the disc and has not yet established a pivot, the marker must wait before starting the stall count. This is to ensure that the thrower is given the opportunity to establish a proper pivot point before the defense can begin counting.

False. According to the rules, prior to the check, the person checking the disc in and the nearest opposition player must verify that their own teammates are ready and positioned as per 10.2. However, the specific rule number given in the question, 10.4, actually refers to the procedure if there is an unnecessary delay in checking the disc in, not the positioning of teammates prior to the check. The correct rule for verifying that teammates are ready and properly positioned is 10.3.

False. According to the rules, if a defensive receiving foul is called and the call is contested, the disc is indeed returned to the thrower. However, the players do not stay where they were when the foul occurred. Instead, they should return to the positions they occupied at the time of the throw, as per the general principle of returning to the last non-disputed position when a call is contested. This is to reset the play to the situation before the contested foul occurred.

When the disc goes out of bounds in Ultimate, the location where it is tapped in depends on where the disc went out. If the disc went out of bounds after being in contact with an offensive player or after being caught by an offensive player who is out of bounds, the disc is brought into play at the point nearest to where the offensive player touched the disc or where the player was out of bounds with the disc (`source_reference`). If the disc went out of bounds without being touched by a player, it is brought into play at the point where it crossed the perimeter line (`source_reference`). If the disc is out-of-bounds and more than three meters from the pivot location, non-players may retrieve the disc, but the thrower must carry the disc the last three meters to the playing field (`source_reference`). When the thrower has the disc and is ready to put it back into play, they must establish a pivot at the appropriate spot on the field. Before play resumes, the thrower must check the disc in. This involves the thrower and the nearest defender acknowledging that both teams are ready to continue. The defender must touch the disc if they are within reach (`source_reference`). The thrower can then either touch the disc to the ground or say "Disc in" to resume play (`source_reference`). If there is any confusion or disagreement about where the disc went out of bounds, and if players with a good perspective cannot agree, the midpoint between the two proposed locations should be used (`source_reference`).

It seems like your question was cut off, but if you're asking whether a disc landing on a player's back after they lay out for it counts as a catch, the answer would depend on whether the player maintains control of the disc. According to the rules of Ultimate, if a receiver dives to receive a pass and catches the disc before it hits the ground, the disc can contact the ground after that, and still be considered "up," as long as the player maintains the catch while the disc is touching the ground. The receiver can change the body parts that are being used to trap the disc, and as long as the disc continues to be trapped by at least one of those sets of body parts during that change, it is considered the same catch. However, if the disc moves and is no longer pinched or controlled in the same spot after hitting the ground, that would not be a maintained catch and therefore would result in a turnover. So, if the player lays out for the disc and it lands on their back, and they maintain control of the disc without it moving out of control, it would count as a catch.

According to the Rules of Ultimate - The Check (10.6), if the defensive team picks up the disc after the offensive team dropped it, they should let the player marking them tap the disc before throwing it. The defender must actively choose to touch the disc, and the thrower cannot initiate the check by tapping the disc against the defender. This ensures that the play is fair and follows the rules of the game.

According to the Rules of Ultimate - The Check (10.6), if there is a defender within reach of the disc, the defender must touch the disc. However, it is not mentioned whether a player can stand over the disc.

Defenders in Ultimate frisbee are not allowed to do several things. Firstly, they are not allowed to guard an offensive player within three meters and react to their movements. Secondly, if there is a defender within reach of the disc, they must touch it. Thirdly, defenders cannot use their arms or legs to obstruct the movement of opposing players. Additionally, if a defender is legally marking the thrower and a second defender commits a double team, the second defender is considered to be the illegally positioned defensive player. Finally, defenders must be legally positioned and cannot take a run-up to make a pass after a turnover, pull, or going out-of-bounds.

A check in ultimate frisbee refers to the act of restarting play after a turnover or a stoppage in play. It involves the thrower initiating play by touching the disc to the ground or saying "Disc In" while the defender is ready to defend. The check ensures that both teams are ready and positioned correctly before play resumes. If there is an unnecessary delay in checking the disc in, the opposition may give a warning called "Delay of Game". If the delay continues, the team that gave the warning may check the disc in by calling "Disc In" without verification from the opposition, but only if the team checking the disc in are all stationary and positioned correctly.

To call a violation in Ultimate frisbee, any opposing player may claim a violation by calling the specific name of the violation or simply saying "Violation," unless specified otherwise by the particular rule. The thrower may also call a marking violation and stop play if there is a marking infraction. Additionally, if the offense breaches certain rules, the defense may give a verbal warning or call a "Violation." It is important to note that a player cannot call a violation if a player on their own team is in the wrong position or is moving before the check. If play should continue without a stoppage, any player recognizing this should announce "play on." If the player who called the breach does not announce "play on" and the opposing team is uncertain whether play should continue, the opposing team has the option to stop play by calling "violation." Remember, it is crucial to use the correct term when making a call, but if a player uses the incorrect name for a call, the call should still be dealt with as if the correct term was used.

According to the Rules of Ultimate - The Check (10.6), if the defensive team picks up the disc after the offensive team dropped it, they should let the player marking them tap the disc before throwing it. The defender must actively choose to touch the disc, and the thrower cannot initiate the check by tapping the disc against the defender. This ensures that the play is fair and follows the rules of the game.
