SDCL § 47-23-5: Special meetings--Electronic communication.

Special meetings of the members of a corporation may be called by the president or by the board of directors. Special meetings of the members may also be called by such other officers or persons or number or proportion of members as may be provided in the articles of incorporation or the bylaws.

The call of a special meeting may provide that the meeting be held by any means of electronic communication that allows the members to:

(1) Substantially see or hear the proceedings concurrently with their occurrence;

(2) Vote on matters submitted to the members; and

(3) Pose questions and make comments.
