blows his whistle an entirely new act of shooting is made.

Art. 11
11.1 Location of a player and an official The location of a player is determined by where he is touching the floor.
While he is in the air from a jump, he retains the same status he had when he last
touched the floor. This includes the boundary line, the centre line, the three-point
line, the free-throw line and the lines delimiting the restricted area.
11.2 If a player who has jumped from his frontcourt establishes new team control while
still airborne, his location relative to backcourt or frontcourt is not determined until
he has again returned to the floor.
The location of an official is determined in the same manner as that of a player.
When the ball touches an official, it is the same as touching the floor at the official's
location.
Jump ball and alternating possession
Definition
A jump ball occurs when an official tosses the ball in the centre circle between any
two opponents at the beginning of the first period.
A held ball occurs when one or more players of each opposing team have one or
both hands firmly on the ball so that neither player can gain control without undue
roughness.
Procedure
Each jumper shall stand with both feet inside the half of the centre circle nearest to
his team’s own basket with one foot close to the centre line.
Team-mates may not occupy adjacent positions around the circle if an opponent
wishes to occupy one of those positions.
The official shall then toss the ball upwards (vertically) between the two opponents,
higher than either of them can reach by jumping.
The ball must be tapped with the hand(s) of at least one or both of the jumpers after
it reaches its highest point.
Neither jumper shall leave his position until the ball has been legally tapped.
Neither jumper may catch the ball or tap it more than twice until it has touched one
of the non-jumpers or the floor.
If the ball is not tapped by at least one of the jumpers, the jump ball shall be retaken. 11.3 Art. 12 12.1 12.1.1 12.1.2 12.2 12.2.1 12.2.2 12.2.3 12.2.4 12.2.5 12.2.6 12.2.7
