Shareholder voting rights may be restricted for unpaid calls or where the company has exercised a lien. The articles may restrict a member's voting rights for shares on which calls or other presently payable sums remain unpaid, or for shares subject to a company's exercised lien; no other grounds may be used to prohibit voting. On a poll, a member, proxy, or other person entitled to vote need not use all votes or cast them in the same way.
