Its all about accountability. There is none. If there was any accountability there would have been a review of the ARC ages ago and it would have been radically overhauled and upgraded, or scrapped.
This is normal modus operandi for the AFL, make a show of good practice, which is the official ARC process, on-field call requires conclusive evidence to overturn, but then routinely, randomly, arbitrarily ignore it. You can't do that if there is an accountability mechanism, especially not repeatedly. They always do the same thing in response to the inevitable legimate criticism, 'tick it off', then go to ground until it blows over.
Was talking to a fellow tiger mate who is a company CEO, he is just amazed that it happened, asked the question is the ARC guy corrupt or leant on to be biased, or an idiot with no concept of dimension or geometry?
Objectively, by the AFLs own official process, and physical reality, it was incompetent or corrupt, or both maybe.
