and situations relating to
So not just foul play for a try, so I would suggest yes, a TMO can suggest it, and it's within this protocol. Of course if he didn't suggest it then again kinda academic!
True enough, but what about this (from the same source), which would seem to indicate they can't consider it:
[LAWS]2.3 If the referee agrees to refer the matter to the TMO he will indicate what the potential offence
was and where it took place. Potential infringements which must be CLEAR and OBVIOUS are
as follows:
• Law 8.1. Scoring points
• Law 9.1 to 9.6 and 10.11 t0 10.23. Foul play: obstruction, dangerous play, tackling a
player without theball
• Law10.4. Offside: player in front of the kicker
• Law 11 Knock-* *on or throw forward
• Law 15.5 to 15.9 Ruck: offside at the ruck – players not joining the ruck
• Law 16.5. Maul: offside at the maul – players not joining the maul
• Law 18.1 and 2. Player in touch
• Law 18.3 to 18.7. Lineout: quick throw
• Law 21 In goal (including ball grounded by a defending player)
• Law 21.7 and 21.8 In goal: Grounding the ball and double movement.
2.4 Referee judgment decisions for all other aspects of the game are not included in the protocol
and may not be referred to the TMO.[/LAWS]
