Something in our responses must have been unclear, as neither of us referenced an Executive Committee. Can you help us out by saying how you got there?
I struggle with a reference given the basic nature, but you might point out that RONR consistently, throughout the book, references the differences between the two sorts of meetings. It has different rules for small boards which never apply in a general assembly. Discipline and bylaw amendment, if the rules in RONR apply, can only be done by membership meetings. It speaks of the board as, in the sort of organization it envisions, subservient to the assembly, which is nonsense if they're the same thing. But I guess I'd ask it the other way: why on Earth would anyone think that, without a delegation of some sort, one body should approve a different body's minutes? Why is that the starting point, and you in need of authority for the opposite? Should my organization approve your organization's minutes while they're at it?
