A player is responsible for their caddie’s actions both during a round and while play is stopped under Rule 5.7a, but not before or after a round.

If the caddie’s action breaches a Rule or would breach a Rule if the action was taken by the player, the player gets the penalty under that Rule.

When application of a Rule depends on whether the player is aware of certain facts, the player’s knowledge is treated as including whatever is known by their caddie.
