Okla. Stat. tit. 18, § 18-437.9: Voting districts

Notwithstanding any other provision of this act, the bylaws may

provide that the territory in which a cooperative supplies electric

energy to its members shall be divided into two or more voting

districts and that, in respect of each such voting district, (1) a

designated number of trustees shall be elected by the members

residing therein, or (2) a designated number of delegates shall be

elected by such members, or (3) both such trustees and delegates

shall be elected by such members. In any such case the bylaws shall

prescribe the manner in which such voting districts and the members

thereof, and the delegates and trustees, if any, elected therefrom

shall function and the powers of the delegates, which may include

the power to elect trustees. No member at any voting district

meeting and no delegate at any meeting shall vote by proxy or by

mail.
