I think the issue is a little more nuanced Malcolm, so I apologize if I oversimplified.  Bylaws consist of words, which are subject to various interpretations.  The Board must interpret and apply the bylaws in light of its fiduciary obligations.  In a membership organization, the SOs and ACs  would have a meaningful way to participate in and effect that interpretation and application process.
