Can't ban a referee from all clubs, but a suspension for a good while backed up by video evidence, for maybe more than one club
Oh, plus, let's get some East Scottish refs, with West ones down to zero, or a trickle, say every 5 new refs, 4 East, 1 West until it's balanced
Rather have a European Circuit of Referees & VAR teams, refereeing everywhere except their own Country
Higher resolution playback and Framerate too; none of this 15FPS frameskipping garbage, like the Scotland Spain and Motherwell Hearts games, where there was definitely 'issues' with the aforementioned aspects of playback on the video presented to referees and the viewing public
Otherwise, it'll continue to be open to abuse
Also, EVERY Penalty shout reviewed; no override like dickinson V killie at home and muir V Ross County
