Also massively undermines the new "bunker" review system.
They have 10 mins to make a proper decision in terms of affecting the game - and then are found not to have done so. Farrell should not have been red carded, should have come back on after 10 mins and restored England to 15 (I think, at that point).
Complete cock up.
Everyone waiting with expectation for the first RC for a high tackle in the RWC now....
