Corp. Code, § 5514

(a) Any form of proxy or written ballot distributed to 10 or more members of a corporation with 100 or more members shall afford an opportunity on the proxy or form of written ballot to specify a choice between approval and disapproval of each matter or group of related matters intended, at the time the written ballot or proxy is distributed, to be acted upon at the meeting for which the proxy is solicited or by such written ballot, and shall provide, subject to reasonable specified conditions, that where the person solicited specifies a choice with respect to any such matter the vote shall be cast in accordance therewith.

(b) In any election of directors, any form of proxy or written ballot in which the directors to be voted upon are named therein as candidates and which is marked by a member “withhold” or otherwise marked in a manner indicating that the authority to vote for the election of directors is withheld shall not be voted either for or against the election of a director.

(c) Failure to comply with this section shall not invalidate any corporate action taken, but may be the basis for challenging any proxy at a meeting or written ballot and the superior court may compel compliance therewith at the suit of any member.
