S.D. Codified Laws § 24-15A-5
The warden shall keep a true record of the conduct of each inmate specifying in the record each infraction of the rules of discipline. Each inmate shall be notified of every entry on the inmate's record of each such infraction of the rules of discipline. The inmate shall have thirty days to challenge, by notifying the warden, the validity of the finding that the inmate committed the rule infraction or the disciplinary sanction imposed. After investigation, the warden may determine that the inmate did not commit the rule infraction and revise the record accordingly. The warden may also modify the imposed disciplinary sanction or rule infraction. The record shall be used by the warden and board in determining the inmate's compliance with the inmate's individual program directive at the time of the inmate's initial parole date. This record may also be used by the board in the determination of discretionary parole releases.
