Well the ref on the pitch shouldn't have to view the replay. Let the video ref call it.
In that case it's doomed to failHe's still in charge of the match though and its his call.
I think they should have the hockey system where you get two free chances to ask for a video replay, and if your appeal is successful you get another chance.
Pathetic the way it was applied. Just ask Rugby Union to run it for them since they seem to be incapable.
Video Ref. should call it immediately (instant replay should take no more than 30 secs) - no need for any delay and no need to defer to the ref.. Why ? It's not a dictatorship, linesmen make calls too.
