I was interested in a ruling from the Italian Referee in the AUS v SCO under 20 match at the Jnr RWC.
There was an attacking lineout on the 5m line, AUS throw. A couple of book ends were in place to set the line, and the jumping pod walked up to the line of touch and they put a jumper up as soon as they reached the line of touch, simultaneous with the throw from the AUS hooker. Pretty much a stock standard "default" lineout option that most teams have in the playbook.
They were penalised (short arm IIRC) and Sir said words to the effect of you can't walk in and jump. I can only presume that AUS was adjudged to be in breach of Law 19.10 (f)
Jumping, supporting or lifting before the ball is thrown. A player must not jump or be lifted or supported before the ball has left the hands of the player throwing in.
The "default" lineout option is used thousands of times every weekend without sanction, and this one didn't seem to be too different from any of those. As a bonus on a difficult day for the AUS U20 lineout, the AUS hooker actually appeared to throw the Gilbert straight and actually hit his jumper. We should have got extra consideration for this rare event.
What also brought a smile to my face was the two penalties against the AUS #9 for not feeding the scrum straight. BRING IT ON, I say. How good would it be if this became a key focus point for ALL referees?
Finally on the subject of lineouts, I have noticed many teams are now using a loose forward as a "receiver"/halfback in defensive lineouts. As soon as the ball is thrown in and before the lineout has ended, this "receiver" gallops infield, beyond the 15 metre line, to line up on the attacking team flyhalf. It seems that coaches are using this as a tactic to counter quick ball off the top of the lineout to their halfback, with the defensive lineout not contesting the ball in the air.
This seems to be in breach of law 19.14(f).
Long throw-in. If the player who is throwing in throws the ball beyond the 15-metre line, a player taking part in the lineout may run infield beyond the 15-metre line as soon as the ball leaves the hands of the player throwing in. If this happens, an opponent may also run infield. If a player runs infield to take a long throw in, and the ball is not thrown beyond the 15-metre line, this player is offside and must be penalised.
Shrewd coaches seem to be exploiting what appears to be a referee blindspot to get a deny the attacking team space by giving a defender a 10 metre headstart before the lineout has ended.
IMHO, there are too many lineout laws for the Match Officials to effectively police, and some effort should be made to simplify the laws to make it easier for Referees to police the remaining laws.
