2. Fair delivery - the arm
For a delivery to be fair in respect of the arm the ball must not be thrown. See 3 below.
Although it is the primary responsibility of the striker's end umpire to ensure the fairness of a delivery in this respect, there is nothing in this Law to debar the bowler's end umpire from calling and signalling No ball if he considers that the ball has been thrown.

(a) If, in the opinion of either umpire, the ball has been thrown, he shall
(i) call and signal No ball.
(ii) caution the bowler, when the ball is dead. This caution shall apply throughout the innings.
(iii) inform the other umpire, the batsmen at the wicket, the captain of the fielding side and, as soon as practicable, the captain of the batting side of what has occurred.

(b.) If either umpire considers that after such caution a further delivery by the same bowler in that innings is thrown, the umpire concerned shall repeat the procedure set out in (a) above, indicating to the bowler that this is a final warning. This warning shall also apply throughout the innings.

© If either umpire considers that a further delivery by the same bowler in that innings is thrown,
(i) the umpire concerned shall call and signal No ball. When the ball is dead he shall inform the other umpire, the batsmen at the wicket and, as soon as practicable, the captain of the batting side of what has occurred.
(ii) the umpire at the bowler's end shall direct the captain of the fielding side to take the bowler off forthwith. The over shall be completed by another bowler, who shall neither have bowled the previous over nor be allowed to bowl the next over.
The bowler thus taken off shall not bowl again in that innings.
(iii) the umpires together shall report the occurrence as soon as possible to the Executive of the fielding side and any Governing Body responsible for the match, who shall take such action as is considered appropriate against the captain and bowler concerned.

3. Definition of fair delivery - the arm
A ball is fairly delivered in respect of the arm if, once the bowler's arm has reached the level of the shoulder in the delivery swing, the elbow joint is not straightened partially or completely from that point until the ball has left the hand. This definition shall not debar a bowler from flexing or rotating the wrist in the delivery swing.
