See Colin L's post - #7My thinking, without combing over the rule book to confirm, was that any breach raised by a player in match play always had to be done without undue delay. Therefore, if the breach happened during the play of a hole, they'd have to raise this issue asap. So, unless there was a valid reason they couldn't inform the player before the end of the hole, they could not simply wait until the players completed the hole, and then simply state the breach on the next tee box? If that were true, it would seem the the answer to the OP was most likely a "No".
I've had a brief look through the rules, and I cannot confirm the above is actually (still) true. Is it a case where any claim can simply wait until beginning the next hole? It seems strange, in that a player could potentially make a breach early on in the hole. For example, on a par 5 they may have played their second shot out of the fairway bunker, and the opponent believe they illegally touched the sand. Can the opponent simply wait for the next 10-15 minutes for players to continue taking their shots, and then after losing / halving the hole THEN make the claim there was a rule breach?
