§ 61. Directors from districts. The by-laws may provide for the use of
one or more of the following: (a) that the territory in which the
corporation has members shall be divided into designated districts, and
that directors shall be nominated or elected therefrom in a designated
number and manner, either by the members therein or by district
delegates elected by such members or by the membership at large; (b)
that primary nominations or elections shall be held in each district to
nominate the directors apportioned to such districts and that the result
of all such primary elections may be ratified by the next regular
meeting of the corporation or may be considered final as to the
corporation; (c) that, in the case of a corporation having local
associations, incorporated or otherwise, affiliated with it or a member
of it, election of a designated number of directors may be by the
members of such local association at a meeting thereof, followed by
transmission of the ballots and of a certified canvass thereof to the
annual meeting of the corporation; (d) that one or more directors may be
appointed by any public official or commission or by the other
directors. Directors so appointed shall represent primarily the interest
of the general public in such corporation; need not be members of the
corporation; and shall not constitute more than one-fifth of the entire
number of directors.
