Law 40 WICKET-KEEPER
1. The Wicket-keeper is the only member of the fielding side allowed to wear gloves and external leg guards.
2. If he takes up a position in the field which does not allow him to discharge the duties of a wicket-keeper, he forfeits the right to wear protective equipment and from immunity the other Laws listed in Law 40.1
3. Gloves must be a specification which excludes webbing between the fingers except that a single piece of flat material may be inserted between index finger and thumb solely as a means of support. This insert shall not form a pouch when the hand is extended.
4. The Wicket-keeper must remain wholly behind the wicket until either (a) the ball touches the strikers bat or person or (b) the ball passes the wicket or (c) the striker attempts to run. If the wicket-keeper contravenes this requirement, the umpire at the strikers end shall call and signal "No Ball" at the instant of delivery.
5. It is unfair for the Wicket-keeper to make significant movement towards the wicket after the ball comes into play. Either umpire shall call and signal "Dead Ball" in the event of such unfair movement. This does not prevent the Wicket-keeper from moving a few paces forward to take a slower delivery.

7. If the striker interferes with the Wicket-keeper whilst legitimately defending his wicket, he shall only be given out as provided for in Law 37.2 (Obstructing a ball from being caught).
