Probably for you, as long as you're not in a Board position and may only demand something from them. I promise that we'll never see Candidates for Board again then.

Says the one who dealt with this subject intensively and enlisted a lawyer for legal advice.

First, you write "following advice" while the rest of your post says "be ruled by". Sneaky.
Second, you're the one making up stuff here that complicates matters for no good reason. The purpose of the association is to give a home for our community and your approach is to exclude them (or their represenative entity respectively)... How sane is that?
Third, you're plain wrong. The autonomy of associations includes the right of self-determination of the Association. This means that the free will of the Association must be fundamentally guaranteed, and the independence of the Association can not entirely be deprived of. Statutory bonds that lead to a muzzling of the Association, because, for example, General Assembly resolutions are made dependent on third-party consent or even can be overruled by third-party decisions, are contrary to morality and are therefore null and void (again, by law).
Search for "Vereinsautonomie" and look out for the minimum limits.
