Yes. Hmm
What's still clearly the same is the indication of where the scrum takes place.
What's changed - or missing - is the instruction NOT to give a dropout when the ball is knocked on over the goal line and then touched down.
Is that an important Law , does that make a difference ? It's certainly a Law that is often cited here , and also a Law that covers a pretty common circumstance .
For me , if there is knock on over the goal line into the in goal and touched down, then to justify a decision of scrum (rather than a 22m) you would need the 2017 Law Book
This has been debated at length in the past but I have not participated because there is no point. When the attacking side knock on in goal then it is a scrum 5M. That is the way it is (or should be) refereed. If anyone disagrees then take it up with WR. Nothing else will change this situation.
When asked about an explanation I simply say that at a knock on by the attacking side in goal there is an opportunity to play an advantage and allow the defending side to play the ball. If the defending doesn’t want to play the ball and touch down instead, then they have made the ball dead. Just as if in open play they make the ball dead in effect by either not doing anything and waiting for the ref to blow his whistle or even knocking on themselves. I have always said that it is within the remit of the referee to decide if he/she can offer an advantage but he/she cannot make a side accept an advantage. Once the opposition decide to try to take an advantage (play with the ball/possession) then it is up to the referee to decide if this has been achieved. Touching down in goal is declining to play with the ball. Therefore scrum for the knock on. Where? – 5M – the only place possible.
