AFAIK, this is not a legal case.
It’s a city council making a ass of itself.
The reason we know about it is that ignorant or foolish politicians are pandering to what they assume, perhaps rightly, are equally ignorant voters. Then demagogic writers jump in and blow it wildly out of proportion and get people all worried that sharia is about to be accepted as law in the USA.
And it simply isn’t true. That so many conservatives buy into these ignorant arguments frankly makes us look kind of foolish.
I certainly like your optimistic view and outlook.
Even if I vehemently disagree with it.
