I think it's fair to say that a provincial court stopping a statutorily approved city council meeting based upon the possibility of the outcome impinging Ford's alleged ability to do his job would take us into a realm well beyond unprecedented.
Rust D'Eye is probably doing what he's told and trying to set some precedents and more power to him, but that's utterly absurd.
He is already declawed and down to one vote. When vodka companies and football teams are shunning you, it's safe bet you're not getting called out to pour coffee on Camp Day at Timmie's or meeting the Prime Minister for a summit. When everyone except your brother votes that you should quit, it's a safe bet no one will stand behind you on legislative matters either. So, you're not really mayor at all anymore, except for a nice necklace and you can tell people that 3 years ago people bought what you were selling and did, in fact, pick you.
But, OK, you just LOVE being mayor (and taxpayers!) so you want to stay...that's your legal prerogative, unfortunately.
But the will of council is paramount and court isn't going to overturn that on a whim. Especially not pre-emptively. And in the amazingly unlikely even they do, then council will go to the premier. Politically it's tricky but if we're dealing with technicalities (like, say, that you can't fire the mayor), she can technically de-amalgamate, rename the city Wynneville, erase it from existence or do just about anything else you can imagine.
It's cute that Ford has finally decided it's time to get the courts to work for him, but even with the best muni lawyer out there, I suspect the victories will be few and far between.
He's done as mayor, whether he gets it or not. I'm guessing that if he manages to run again in the fall, he gets 15-20% of the vote, tops. (Hard to take a better guess not knowing what 500 other things will come out between now and then.)
