S.D. Codified Laws § 16-19-24
There is hereby established a seven member board to be known as "the disciplinary board of the State Bar of South Dakota" (hereinafter referred to as the "board"). The president of the State Bar shall appoint six active members of the State Bar, and the Chief Justice shall appoint one lay member. The lay member shall be a resident of South Dakota and twenty-one years of age or more. Attorney vacancies shall be filled by the president of the State Bar, and a lay vacancy shall be filled by the Chief Justice.
The term of service for members shall be one term of five years. Except as provided herein, no member shall serve for more than five years. An appointment to fill an unexpired term shall not constitute an appointment prohibiting an appointment for a subsequent term provided that the appointment for an unexpired term does not exceed three years. It is the intent of this rule to provide for the orderly and systematic rotation of board members such that not more than two attorney members complete terms each calendar year. In the event of death, disability, or resignation, resulting in multiple members completing terms in a single calendar year and in order to restore the systematic rotation of board membership, the term of appointment by the appointing person may be either shortened or extended, not to exceed two years' deviation from a five year term.
