The language in the Charter is, "by the affirmative vote of 2/3 of all members entitled to vote under the bylaws then existing."
The language in the Secretary of State's approval of the amendment for the name change was, "amendment received at least two-third of the votes entitled to be cast by members present or represented by proxy at such meeting." The SOS accepted this as the vote required to change the Charter.
Do these 2 statements imply equivalent things? The SOS accepted "2/3 of votes entitled to be cast by members present..." to make a change to the Charter. If the SOS made this interpretation to amend the Charter, can the association make the same interpretation to amend the Bylaws, as referenced in the Charter in the language, "two-thirds of all members entitled to vote under the bylaws then existing" to mean the same thing, ie: 2/3 of the votes entitled to be cast at the annual meeting?
In the case of ambiguity in the Charter, can we use the same recommendations for ambiguity in the bylaws (pp 588-589)? "The interpretation should be in accordance with the intention of the society at the time the bylaw was adopted, as far as this can be determined. Again, intent plays no roles unless the meaning is unclear or uncertain, but where ambiguity exists, a majority vote is all that is required to decide the question. The ambiguous or doubtful expression should be amended as soon as practicable."
