(a) The board may refuse to issue, refuse to renew, refuse to reinstate, suspend, revoke eligibility for licensure, or revoke a peace officer or part-time peace officer license for any of the following causes:
Subd. 2. Discovery of disqualifying conviction after licensure.
The board may suspend or revoke a peace officer or part-time peace officer license when the licensee has been convicted of a crime recognized by the board as a crime that would disqualify the licensee from participating in a professional peace officer education course, taking the peace officer licensing examination or the part-time peace officer licensing examination, or maintaining eligibility for licensure under Minnesota Rules, chapter 6700. The authority to suspend or revoke a license shall include all individuals who have been granted a license when a disqualifying conviction that would have precluded eligibility for licensure is discovered after licensure.
