Laws of Cricket 1947 Code (Second Edition) - Law 25
The ball shall be held to be "dead" - on being in the opinion of the Umpire finally settled in the hands of the Wicket-keeper or of the Bowler; or on reaching or pitching over the boundary; or, whether played or not, on lodging in the dress of either a Batsman or Umpire; or on the call of "Over" or "Time" by the Umpire; or on a Batsman being out from any cause; or on any penalty being awarded under Laws [21] or [44]. The Umpire shall call "Dead Ball" should he decide to intervene under [Law 46] in a case of unfair play or in the event of a serious injury to a player; or should he require to suspend play prior to the Striker receiving a delivery. The ball shall cease to be "Dead" on the Bowler starting his run or bowling action.
Notes on Law 25
- Whether the ball is "finally settled" is a question of fact for the umpire alone to decide.
- An umpire is justified in suspending play prior to the striker receiving a delivery in any of the following circumstances:
- If satisfied that, for an adequate reason, the striker is not ready to receive the ball, and makes no attempt to play it.
- If the bowler drops the ball accidentally before delivery, or if the ball does not leave his hand for any reason.
- If one or both bails fall from the striker's wicket before he receives the delivery.
- A ball does not become "Dead" when it strikes an umpire (unless it lodges in his dress), when the wicket is broken or struck down (unless a batsman is out thereby), or when an unsuccessful appeal is made.
- For the purpose of this and other Laws, the term "dress" includes the equipment and clothing of players and umpires as normally worn.
