(a) The umpire shall ascertain whether the bowler intends to bowl right handed or

left handed, over or round the wicket, and shall so inform the striker.

It is unfair if the bowler fails to notify the umpire of a change in his mode of

delivery. In this case the umpire shall call and signal No ball.

(b) Underarm bowling shall not be permitted except by special agreement before

the match.

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.

(c) 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.

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.

If the bowler throws the ball towards the striker’s end before entering his delivery

stride, either umpire shall call and signal No ball. See Law 42.16 (Batsmen

stealing a run). However, the procedure stated in 2 above of caution, informing,

final warning, action against the bowler and reporting shall not apply.

For a delivery to be fair in respect of the feet, in the delivery stride

(i) the bowler’s back foot must land within and not touching the return crease.

(ii) the bowler’s front foot must land with some part of the foot, whether

grounded or raised, behind the popping crease.

If the umpire at the bowler’s end is not satisfied that both these conditions have

been met, he shall call and signal No ball.

The umpire at the bowler’s end shall call and signal No ball if a ball which he

considers to have been delivered, without having previously touched the bat or

person of the striker,

either (i) bounces more than twice

or (ii) rolls along the ground

before it reaches the popping crease.

If a ball delivered by the bowler comes to rest in front of the line of the striker’s

wicket, without having touched the bat or person of the striker, the umpire shall

call and signal No ball and immediately call and signal Dead ball.

In addition to the instances above, an umpire shall call and signal No ball as

required by the following Laws.

Law 40.3 - Position of wicket-keeper

Law 41.5 - Limitation of on side fielders

Law 41.6 - Fielders not to encroach on the pitch

Law 42.6 - Dangerous and unfair bowling

Law 42.7 - Dangerous and unfair bowling – action by the umpire

Law 42.8 - Deliberate bowling of high full pitched balls.

An umpire shall revoke the call of No ball if the ball does not leave the bowler’s

hand for any reason.

A call of No ball shall over-ride the call of Wide ball at any time. See Law 25.1

(Judging a Wide) and 25.3 (Call and signal of Wide ball).

The ball does not become dead on the call of No ball.

A penalty of one run shall be awarded instantly on the call of No ball. Unless the

call is revoked, this penalty shall stand even if a batsman is dismissed. It shall be

in addition to any other runs scored, any boundary allowance and any other

penalties awarded.

The one run penalty for a No ball shall be scored as a No ball extra. If other

penalty runs have been awarded to either side, these shall be scored as in Law

42.17 (Penalty runs). Any runs completed by the batsmen or a boundary

allowance shall be credited to the striker if the ball has been struck by the bat;

otherwise they also shall be scored as No ball extras.

Apart from any award of a 5 run penalty, all runs resulting from a No ball,

whether as No ball extras or credited to the striker, shall be debited against the

bowler.

A No ball shall not count as one of the over. See Law 22.4 (Balls not to count in

the over).

When No ball has been called, neither batsman shall be out under any of the Laws

except 33 (Handled the ball), 34 (Hit the ball twice), 37 (Obstructing the field) or

38 (Run out).
