TBH dont think he has the right at all! i think thats a stevo rule! players can tell by signal given by the ref. but ref's seem to be the biggest influence on the game instead of the player!!!

It was my understanding they did. Our resident Championship official Bonzo will clarify I'm sure!

I just found it completely bemusing that we knocked on and were awarded a try from the resulting play

I'll allow a Captain to ask for clarification no problem, but I generally explain my decisions anyway so that they know what they've done wrong. You do get some captains who think they can question everything though, regardless of how clear cut the decision is. If they're taking it too far I tell them to leave it, and if they don't then they get penalised.

As stated though, I'm only speaking for the way I handle those situations - although what I've heard on TV and at live games, that's how a lot of others handle them too.
