Question

Mention any four instances when the umpire signals a no-ball.

Answer 1

Instances when the umpire signals a no-ball are:

1. Mode of delivery: The umpire shall ascertain whether the bowler intends to bowl right-handed or left-handed, over or around 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.
2. Fair delivery - the arm: For a delivery to be fair in respect of the arm the ball must not be delivered with an Illegal Bowling Action. An Illegal Bowling Action is defined as a bowling action where a bowler's Elbow Extension exceeds 15 degrees, measured from the point at which the bowling arm reaches the horizontal until the point at which the ball is released (any Elbow Hyperextension shall be discounted for the purposes of determining an Illegal Bowling Action).
3. Bowler breaking wicket in delivering ball: Either umpire shall call and signal No ball if, other than in an attempt to run out the non-striker under clause 41.16, the bowler breaks the wicket at any time after the ball comes into play and before completion of the stride after the delivery stride. This shall include any clothing or other object that falls and breaks the wicket.
4. Bowler throwing towards striker's end before delivery: If the bowler throws the ball towards the striker's end before entering the delivery stride, either umpire shall call and signal no-ball.
