Not going to comment on the actual decision as didn't watch the game but here is what the previous poster is after from section 11 - the tackle

BTW, law book is available for free from the RLIF website.

Verbal instructions 6. If any doubt arises as to a tackle, the Referee to should
resolve doubt give a verbal instruction to “play on” or shout “held” as
the case may be. If the referee is of the opinion that the
player in possession could not hear the “held” call before
passing or running off with the ball he should instruct the
player to play the ball at the point where the player was
when “held” was called unless it occurs after the fifth play
the ball in which case a handover will apply.

Speed essential 11. The play-the-ball must be performed as quickly as
possible. Any player who intentionally delays the bringing
of the ball into play shall be penalised.

Without meaning to drag this thread on. We bumped into Bentham and the officials in a bar after the game.

He explained to us that a if a player is still in a standing position and moves off the mark after held is called then the player is asked to go back and the play the ball, as its difficult for that player to know when they are actually held if they don’t hear the call.

In Escare’s case he explained that because the players ball carrying arm had hit the floor and there was a player on him, the tackle was indeed complete and the player should have known it was complete and therefore cannot get back up and run away.

If Escare was tackled by Lee in the same way near the try line and decided to reach over and score it quite rightly would have been a penalty for a double movement and he wouldn’t have just been asked to the play the ball again. Escare was held and decided to get up and run, therefore the penalty was correct. Cummings made the wrong call on sky.

So what people are saying on here is that Harrison should have been given the chance to play the ball again after his disallowed try? And so should any player who ever gets penalised for a double movement? H didn't know he was tackled and reached over line so it should have been play the to Salford should it? Give over both decisions were correct. Its amazing how many rugby league fans/pundits actually have no idea about the rules, embarrassing

Well it's kinda nice to think you can approach a ref in a bar after the match and have a conversation like that. Fair play to Bentham. And yes, I fully agree, he was surely dead right in this case.

This.

That.

But not the other.
