Local government did something similar in Berlin, Germany.

Anti-lockdown protesters wanted to register a demonstration. Local left-wing government didn't like it and denied it. Protesters sued and the court said the demonstration can go ahead. Local government vindictively imposed all kinds of restrictions (masks, minimum distance, etc), forced protesters into a small area and when they couldn't meet the restrictions because of that the government dissolved the demonstration.

Of course the very same government was totally fine with BLM protests running wild with zero restrictions, massive crowds without masks and zero distancing and all.
