Who should remove chalk marks from a bowl which is a non-toucher?

In the context of bowls, when a bowl is deemed a non-toucher, it signifies that it has not made contact with the jack or any of the other bowls in play. The responsibility of removing chalk marks from such a bowl falls to a member of the opposing team. This is to maintain the integrity of the game and ensure that there is no undue influence or alteration of the bowl's condition by the player who delivered it. Allowing the opposing team to handle the non-toucher ensures fairness and impartiality in the conduct of the game.

Moreover, it’s important for players to respect the roles and responsibilities designated in the rules of play. This helps to establish clear boundaries about who is responsible for various actions during a match, further promoting a spirit of sportsmanship and compliance with the rules.
