I have long contended that the 1st amendment right to peaceful assembly covers the assembly for the purpose of conducting business. As such, it also incorporates the right to NOT assemble. Thus it takes both parties to agree to conduct business. If one party does not wish to conduct business, then no business should be conducted.
Granted that is not how the left or current court rulings have aligned.
However, there have been a series of federal district court cases involving several dioceses of The Episcopal Church that have sued to be allowed to split from the main church. The Episcopal Church went to court to keep the diocese intact.
The courts have ruled that the diocese have a right to disassociate as a derivation of the right to assemble.
