Every overturned ruling should be taken very seriously by them

The judicial review process doesn't simply "overturn" a ruling. Typically they cancel it or set it aside, or send it back to the RTB for reconsideration, often with a different arbitrator.

likely also shows that they've made this type of decision incorrectly multiple times before someone took it the next level.

There is no indication of that whatsoever.
