2. Fair and unfair play - responsibility of umpires
The umpires shall be the sole judges of fair and unfair play. If either umpire considers an action, not covered by the Laws, to be unfair, he shall intervene without appeal and, if the ball is in play, shall call and signal Dead ball and implement the procedure as set out in 18 below. Otherwise the umpires shall not interfere with the progress of play, except as required to do so by the Laws.
6. Dangerous and unfair bowling
(a) Bowling of fast short pitched balls
(i) The bowling of fast short pitched balls is dangerous and unfair if the umpire at the bowler's end considers that by their repetition and taking into account their length, height and direction they are likely to inflict physical injury on the striker, irrespective of the protective equipment he may be wearing. The relative skill of the striker shall be taken into consideration.
(ii) Any delivery which, after pitching, passes or would have passed over head height of the striker standing upright at the crease, although not threatening physical injury, shall be included with bowling under (i) both when the umpire is considering whether the bowling of fast short pitched balls has become dangerous and unfair and after he has so decided. The umpire shall call and signal No ball for each such delivery.
(b) Bowling of high full pitched balls
(i) Any delivery, other than a slow paced one, which passes or would have passed on the full above waist height of the striker standing upright at the crease is to be deemed dangerous and unfair, whether or not it is likely to inflict physical injury on the striker.
(ii) A slow delivery which passes or would have passed on the full above shoulder height of the striker standing upright at the crease is to be deemed dangerous and unfair, whether or not it is likely to inflict physical injury on the striker.
7. Dangerous and unfair bowling - action by the umpire
(a) As soon as the umpire at the bowler's end decides under 6(a) above that the bowling of fast short pitched balls has become dangerous and unfair, or, except as in 8 below, there is an instance of dangerous and unfair bowling as defined in 6(b) above, he shall call and signal No ball and, when the ball is dead, caution the bowler, inform the other umpire, the captain of the fielding side and the batsmen of what has occured. This caution shall continue to apply throughout the innings.
(b) If there is any further instance of dangerous and unfair bowling by the same bowler in the same innings, the umpire at the bowler's end shall repeat the above procedure and indicate to the bowler that this is a final warning.
Both the above caution and final warning shall continue to apply even though the bowler may later change ends.
(c) Should there be any further repetition by the same bowler in that innings, the umpire shall
(i) call and signal No ball.
(ii) direct the captain, when the ball is dead, 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 be allowed to bowl again in that innings.
(iii) report the occurrence to the other umpire, the batsmen and, as soon as practicable, the captain of the batting side.
(iv) report the occurrence, with the other umpire, as soon as possible to the Executive of the fielding side and to any Governing Body responsible for the match, who shall take such action as is considered appropriate against the captain and bowler concerned.
8. Deliberate bowling of high full pitched balls
If the umpire considers that a high full pitch which is deemed to be dangerous and unfair, as defined in 6(b) above, was deliberately bowled, then the caution and warning prescribed in 7 above shall be dispensed with. The umpire shall
(a) call and signal No ball.
(b) direct the captain, when the ball is dead, to take the bowler off forthwith.
(c) implement the remainder of the procedure as laid down in 7(c) above.
9. Time wasting by the fielding side
It is unfair for any member of the fielding side to waste time.
(a) If the captain of the fielding side wastes time, or allows any member of his side to waste time, or if the progress of an over is unnecessarily slow, at the first instance the umpire shall call and signal Dead ball if necessary and
(i) warn the captain, and indicate that this is a first and final warning.
(ii) inform the other umpire and the batsmen of what has occurred.
(b) If there is any further waste of time in that innings, by any member of the fielding side, the umpire shall
either (i) if the waste of time is not during the course of an over, award 5 penalty runs to the batting side. See 17 below.
or (ii) if the waste of time is during the course of an over, when the ball is dead, direct the captain to take the bowler off forthwith. If applicable, 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 be allowed to bowl again in that innings.
(iii) inform the other umpire, the batsmen and, as soon as practicable, the captain of the batting side of what has occurred.
(iv) report the occurrence, with the other umpire, as soon as possible to the Executive of the fielding side and to any Governing Body responsible for the match, who shall take such action as is considered appropriate against the captain and team concerned.
10. Batsman wasting time
It is unfair for a batsman to waste time. In normal circumstances the striker should always be ready to take strike when the bowler is ready to start his run up.
(a) Should either batsman waste time by failing to meet this requirement, or in any other way, the following procedure shall be adopted. At the first instance, either before the bowler starts his run up or when the ball is dead, as appropriate, the umpire shall
(i) warn the batsman and indicate that this is a first and final warning. This warning shall continue to apply throughout the innings. The umpire shall so inform each incoming batsman.
(ii) inform the other umpire, the other batsman and the captain of the fielding side of what has occurred.
(iii) inform the captain of the batting side as soon as practicable.
(b) if there is any further time wasting by any batsman in that innings, the umpire shall, at the appropriate time while the ball is dead
(i) award 5 penalty runs to the fielding side. See 17 below.
(ii) inform the other umpire, the other batsman, the captain of the fielding side and, as soon as practicable, the captain of the batting side of what has occurred.
(iii) report the occurrence, with the other umpire, as soon as possible to the Executive of the batting side and to any Governing Body responsible for the match, who shall take such action as is considered appropriate against the captain and player or players and, if appropriate, the team concerned.
15. Bowler attempting to run out non-striker before delivery
The bowler is permitted, before entering his delivery stride, to attempt to run out the non-striker. The ball shall not count in the over.
The umpire shall call and signal Dead ball as soon as possible if the bowler fails in the attempt to run out the non-striker.
18. Players' conduct
If there is any breach of the Spirit of the Game by a player failing to comply with the instructions of an umpire, or criticising his decisions by word or action, or showing dissent, or generally behaving in a manner which might bring the game into disrepute, the umpire concerned shall immediately report the matter to the other umpire.
The umpires together shall
(i) inform the player's captain of the occurrence, instructing the latter to take action.
(ii) warn him of the gravity of the offence, and tell him that it will be reported to higher authority.
(iii) report the occurrence as soon as possible to the Executive of the player's team and any Governing Body responsible for the match, who shall take such action as is considered appropriate against the captain and player or players, and, if appropriate, the team concerned.
