On the halfback thing, this is my understanding, although I don't have the data to hand. It was always a grey area, almost an "understood" aspect of the game that you don't grab the halfback. Then players started doing it and they (the refs, the iRB) couldn't find any rule against it. So they recently (6-12 months ago) instituted a law interpretation which essentially states that you can't interfere with the halfback.
Referees have always used conventions in their interpretations of the law and this is one of the good ones. Its practice has been going on longer than you say though.
Usually there
are laws infringed when a defending player in the ruck grabs the scrummie.
• the main one is that you can't pull a player who is not in the ruck, into the ruck; you can only bind onto him if he is there.
• also you can't do anything, let alone grab an opposing player, if you are not on your feet. And you are deemed not to be on your feet if you have a bit of weight on your belly against other players in the ruck as you lean over to grab the scrummie.
• if these two law infringements fail, the ref can decide that you were not bound to other players to start with as you have to be and that you charged through a ruck unbound. What a crime.
It seems as though the only way to grab the scrummie legally is when you are on your feet, with no weight borne by other players, and to grab him with one arm with the other one bound.
And ..... a defender had better make sure that the ball is out of the ruck before he does his one armed grab.
It is no use saying that I was bound but when the scrummie got the ball out the ruck was over so I could grab him with both hands.
It is also no use saying that the ruck was over because the scrummie had his hands on the ball and if it wasn't over then the scrummie should be penalised for having his hands in the ruck [as they always were until referees started turning a blind eye to that 30-40 years ago.]
One ref in the TNC at Uni Oval a few years back answered a remark by a defending player that the scrummie had his hands on the ball so the ruck should have been over and he not offside, with the words: "Hands on is not ball out."
The referee would struggle to find that law in his handbook because it is not there. It is in the unwritten CORTBFBWRITWTRAHL - "Conventions Of Referees To Be Followed By Wannabe Referees If They Want To Referee At Higher Levels".
Players should not grab scrummies if they are in the ruck, however well they comply with the written law, because they will get pinged under the provisions of the CORTBFBWRITWTRAHL. These conventions are hard to toss and they pop up everywhere especially if referees are lazy or not alert. Players should follow these unwritten "laws". and the probability of getting pinged, even when they know they are in the right.
For example: they are more likely to get whistled up in their own red zone charging around to the back of an attacking ruck even though the ball has technically passed the line of last feet. It is too much of a risk, as young All Black Isaac Ross realised as he sat down after being carded at Absa Stadium.
CORTBFBWRITWTRAHL can be a bitch.
