SDCL § 36-4-29: Grounds for cancellation, revocation, suspension or limitation of license, resident license, or certificate.

The Board of Examiners may cancel, revoke, suspend, or limit the license, resident license, or certificate of any physician or surgeon issued under this chapter upon satisfactory proof by a preponderance of the evidence in compliance with chapter 1-26 of such a licensee's, resident licensee's, or certificate holder's professional incompetence, or unprofessional or dishonorable conduct, or proof of a violation of this chapter in any respect. However, the board may not base a finding of unprofessional or dishonorable conduct solely on the basis that a licensee, resident licensee, or certificate holder practices chelation therapy.

For the purposes of this section, professional incompetence is a deviation from the statewide standard of competence, which is that minimum degree of skill and knowledge necessary for the performance of characteristic tasks of a physician or surgeon in at least a reasonably effective way.
