33. INTERFERENCE WITH A BALL

1. OUTSIDE AGENCY OR PLAYER If an outside agency or a player (except the striker during the striking period) touches a ball during a stroke:
   1. the striker must replay the stroke if:
      1. no further stroke has been played; and
      2. the interference might have prevented a point being scored, a roquet being made, or a ball coming to rest in a critical position; and
      3. the interference was caused by an outside agency that moved or came to rest after the striker finally took up his stance, or by the adversary.
   2. otherwise, there is no replay and all balls must be placed as near as possible to where they would have been at the end of the stroke had the interference not occurred. (See Law 48(f) if the players' opinions differ).
2. NATURAL FORCES If a ball is affected by natural forces, e.g. wind or gravity, during a stroke, it must be replaced if it was not moved by the stroke. Otherwise there is no remedy.
3. BETWEEN STROKES If a ball moves or is unlawfully moved between strokes it must be replaced.
4. INTERACTION WITH OTHER LAWS
   1. After relevant interference, a ball may not score a point, make a roquet nor be roqueted.
   2. In a croquet stroke, the turn ends under Law 20(c) if either ball would have gone off the court had the interference not occurred; it does not end merely because a ball went off as a result of interference.
   3. If a ball is not correctly placed or replaced before the next stroke , it becomes misplaced and Law 27(a) applies.
