But I wasn't quoting law, but the guidelines as to how we (as in ARU land) are supposed to interpret the laws.
For your benefit here is the ARU game management guidelines on lifting tackles.
"Lifting tackles that place players in danger of injury must have serious consequences. The onus is on the tackler to complete the tackle safely. Dropping or throwing tackled players once they are in a dangerous position is to be strongly sanctioned.
Any time a tackled player's legs are lifted above horizontal it should result in a yellow card as a minimum.
If the tackled player is lifted and lands on his shoulder or head area it should result in a red card. A tackled player placing a hand down at the last second to stop a 'head or shoulder area landing' should not influence this sanction."
I'm aware of the guideline. My point was that even if the guideline was to be taken to refer only to the situation when
both a player's legs are taken above the horizontal (not an inevitable, nor necessarily the most likely, construction), the Law itself doesn't, and the preamble to the guideline doesn't suggest that it represents the only situation in which a YC/RC should be considered for breach of the Law
As for construction of the guideline: if the dress code for a function says that "T-shirts shall not be worn", does that mean that I am OK if I only wear one T-shirt?
Or, closer to the specific subject: the guideline says that "Dropping or throwing tackled player
s once they are in a dangerous position..."; does that mean that provided I only drop or throw one player I'm outside the guideline?
FWIW, the first video illustrating Law 10.4(j) is the Warburton/LeClerc tackle; the second is a tackle similar to the tackle on McKinnon (from which I wish him the best for recovery), with only one leg lifted and the other following. If White 5 hadn't got his arm out, it looked an even more dangerous tackle than the Warburton/LeClerc one.
