Quote: John Charnock "It means the linesman didn't know, in which case it was up to the ref to make a decision, with the aid of the in-goal official if he saw it clearly, which as you say he probably didn't. Benefit of the doubt to the attacking team.
You don't often see it but a horizontal wave of the flag is one option the touch judge has when adjudicating on a goal kick - up for a goal, down for a miss, horizontal for a don't know. If one touch judge makes a decision and the other is a don't know, the referee can overrule the one who made the decision. If both touch judges agree the referee has to accept their decision.'"
Granted not the horizontal flag waving but I'm sure this season we've had it twice in the same game where the 2 touch judge's made differing desicions for a goal kick and the ref gave one and dismissed the other.
I remember being rather upset about one of them, lol.
