The "senatorial district committee" of a party shall consist of those members of the county committee residing in a senatorial district. A senatorial district committee may encompass less than an entire county or may extend across county lines. Such a committee shall elect its own officers when called upon to meet, but it need not meet unless required to perform some function under this title. Any three members may call the first meeting by giving at least five days' written notice to all other members; thereafter, the committee shall meet at the call of the chair. (Added 1977, No. 269 (Adj. Sess.), § 1; amended 2003, No. 59, § 9.)
