45. They shall allow two minutes for each striker to come in, and ten minutes between each innings. When they shall call “Play,” the side refusing to play shall lose the match.
46. They shall not order a batsman out unless appealed to by the other side.
N.B.—An appeal, “How’s that,” covers all ways of being out (within the jurisdiction of the umpire appealed to), unless a specific way of getting out is stated by the person asking.
47. The umpire at the bowler’s wicket shall be appealed to before the other umpire in all cases, except in those of stumping, hit wicket, run out at the striker’s wicket, or arising out of Law 42, but in any case in which an umpire is unable to give a decision, he shall appeal to the other umpire, whose decision shall be final.
48. If either umpire be not satisfied of the absolute fairness of the delivery of any ball, he shall call “No ball.”
48A. The umpire shall take especial care to call “No ball” instantly upon delivery: “Wide ball” as soon as it shall have passed the striker.
49. If either batsman run a short run, the umpire shall call “One short,” and the run shall not be scored.
50. After the umpire has called “Over,” the ball is “Dead,” but an appeal may be made as to whether either batsman is out; such appeal, however, shall not be made after the delivery of the next ball, nor after any cessation of play.
51. No umpire shall be allowed to bet.
52. No umpire shall be changed during a match, unless with the consent of both sides, except in case of violation of Law 51; then either side may dismiss him.
