The Key Match Incident Review Panel have unanimously agreed that Rangers should have been awarded a penalty against Celtic - as they branded the flashpoint a simple decision that ALL officials should get right.
All five members of the independent panel agreed that VAR should have intervened to award a penalty after Vaclav Cerny was pulled down by Liam Scales.
John Beaton awarded a free-kick but replays showed Cerny's foot was on the line of the penalty box meaning a spot-kick should have been given.
Alan Muir, on VAR duties, did not step in over the incident with Willie Collum admitting an "unacceptable" error was made in the officiating.
The KMI review panel have now issued their verdict with all five members confident a penalty should have been given.

And the difficulty rating of the incident was scored at just one out of five, making it "a simple decision that all officials should get correct".
The KMI notes on the matter read: "The panel unanimously agreed that the incorrect decision was reached.
"A penalty-kick should have been awarded after a factual review as the holding continued inside the penalty-area."
The KMI review panel update also revealed a unanimous verdict on the potential foul in the lead up to Nico Kuhn's strike for Celtic.
The attacking phase of play was checked by VAR for a possible foul but the goal was allowed to stand - with the panel all agreeing that was the correct decision.
