Is it. Do you know or are you surmising? If so, that is exactly what I was querying.
Yes, I know this. The TMO can be used for:
1. A potential infringement by a try scoring team.
2. Review potential acts of foul play
In the Hoffman situation, it would have been outside of protocol to check replay footage when the ball went into touch. Personally I am very comfortable with this as I would not like to see the game severely slowed down by a lot of checking of close calls.
When the try was scored, you may argue that he should then check. I have 3 issues with this. The potential length of time and amount of game that has passed, the fact that the TMO protocol only allows to look for infringements of the scoring team not errors from the referee and lastly, the Waratahs would rightfully be outraged if a try was denied by the TMO when they hadn't infringed.
My last point brings a separate discussion. If it was within protocol to check this scenaro with the TMO, how would you determine the materiality of the impact of the referee error of restarting the game in the wrong position. If the lineout position was only impacted by 5m by the referee error, did this give the scoring team an unfair advantage? What if the Rebels had taken an intercept and scored - could it be over-ruled due to the game starting in the wrong position?
