Yes, it is part of the freedom of association/assembly/speech.
Ok, yeah I figured, but didn’t want to assume.
This could be a really simple response, but considering what’s been laid out here, it seems that detail will help.
When God made Man, he made man with the ability to decide.
Something humans decide in almost all cultures is that they want to assign folks (governments and associated departments) with the responsibility to decide on the rules and run the logistics for the larger society. Some societies might have a strong arm that pushes to the front of the pack, but that’s not the situation with the subject.
Those decisions are not always pleasing to all people in society. However, the alternative is either more hands in the cookie jar where everyone’s hand is stuck, no cookies for anybody (assembly being one), or no cookie jar where cookie crumbs are all over the floor, and there is just a big mess (chaos).
Assembly is one of those things that society has to be involved in for security, health / nourishment, traffic adjustments, emergency routes, etc…
So, with all the organization and assistance necessary from government to pull off assembly, I can only hope that you might see how humans are the source of the decision to allow assembly.
It is not a right from God to disrupt lives so I can stand around with my like minded friends, it is thanks to the rest of society for allowing it, if they write it into law.
Therefore, it is absolutely societies right to cancel one.
Obviously none of this brings in the moral issue, right and wrong in God’s eyes, which is a source for laws created by man.
Take care,
