Cal. Corporations Code § 9920

(a) The provisions of Chapter 5 (commencing with Section 5510) and Chapter 6 (commencing with Section 5610) of the new Public Benefit Corporation Law apply to any meeting of members of a public benefit corporation, the provisions of Chapter 5 (commencing with Section 7510) and Chapter 6 (commencing with Section 7610) of the new Mutual Benefit Corporation Law apply to any meeting of members of a mutual benefit corporation, and the provisions of Chapter 4 (commencing with Section 9410) of the new Religious Corporation Law apply to any meeting of members of a religious corporation, held on or after January 1, 1980, and to any action by such members pursuant to a written ballot, which becomes effective on or after January 1, 1980, and to any vote cast at such a meeting or ballot, given for such action (whether or not a proxy or ballot was executed by the member prior to January 1, 1980). (b) Notwithstanding subdivision (a): (1) The prior nonprofit law shall apply to any such meeting of members and to any vote cast at such a meeting if such meeting was initially called for a date prior to January 1, 1980, and notice thereof was given to members entitled to vote thereat; and (2) Where a proxy would be valid under the prior nonprofit law but would not be valid for a public benefit corporation under the new Public Benefit Corporation Law, for a mutual benefit corporation under the new Mutual Benefit Corporation Law, or for a religious corporation under the new Religious Corporation Law, and where the proxy by its terms expires during or after 1980, such proxy may be voted at meetings of members during 1980 (prior to its expiration date) but not thereafter. (3) Action taken by the board or the members after December 31, 1979, and before January 1, 1982, shall be valid if such action was taken in compliance with the prior nonprofit law and the articles and bylaws as they then existed, subject to the rights of any person who acted in detrimental reliance upon the invalidity of such action prior to Janaury 1, 1982. This subdivision does not validate any provision in the articles or bylaws after December 31, 1981, which does not comply with the then existing provisions of the new public benefit, mutual benefit, or religious corporation law, as the case may be.
