(a) The council shall have authority to refuse to grant a certificate to an applicant or to discipline a certified peace officer or exempt peace officer under this chapter or any antecedent law upon a determination by the council that the applicant or certified peace officer or exempt peace officer has:

(1) Failed to demonstrate the qualifications or standards for a certificate provided in this chapter or in the rules and regulations of the council. It shall be incumbent upon the applicant to demonstrate to the satisfaction of the council that he meets all requirements for the issuance of a certificate;

(2) Knowingly made misleading, deceptive, untrue, or fraudulent representations in the practice of being a peace officer or in any document connected therewith or practiced fraud or deceit or intentionally made any false statement in obtaining a certificate to practice as a peace officer;

(3) Been convicted of a felony in the courts of this state or any other state, territory, country, or of the United States. As used in this paragraph, the term "conviction of a felony" shall include a conviction of an offense which if committed in this state would be deemed a felony under either state or federal law without regard to its designation elsewhere. As used in this paragraph, the term "conviction" shall include a finding or a verdict of guilt, a plea of guilty, or a plea of nolo contendere in a criminal proceeding, regardless of whether the adjudication of guilt or sentence is withheld or not entered thereon. However, the council may not deny a certificate to an applicant with a conviction if the adjudication of guilt or sentence is withheld or not entered thereon;

(4) Committed a crime involving moral turpitude, without regard to conviction. The conviction of a crime involving moral turpitude shall be conclusive of the commission of such crime. As used in this paragraph, the term "conviction" shall have the meaning prescribed in paragraph (3) of this subsection;

(5) Had his certificate or license to practice as a peace officer revoked, suspended, or annulled by any lawful certifying or licensing authority; or had other disciplinary action taken against him by any lawful certifying or licensing authority; or was denied a certificate or license by any lawful certifying or licensing authority;

(6) Engaged in any unprofessional, unethical, deceptive, or deleterious conduct or practice harmful to the public, which conduct or practice need not have resulted in actual injury to any person. As used in this paragraph, the term "unprofessional conduct" shall include any departure from, or failure to conform to, the minimal standards of acceptable and prevailing practice of a peace officer;

(7) Violated or attempted to violate a law, rule, or regulation of this state, any other state, the council, the United States, or any other lawful authority without regard to whether the violation is criminally punishable, which law, rule, or regulation relates to or in part regulates the practice of a peace officer; (8) Committed any act or omission which is indicative of bad moral character or untrustworthiness;

(9) Been adjudged mentally incompetent by a court of competent jurisdiction, within or outside this state;

(10) Become unable to perform as a peace officer with reasonable skill and safety to citizens by reason of illness or use of alcohol, drugs, narcotics, chemicals, or any other type of material or as a result of any mental or physical condition; or

(11) Been suspended or discharged by the peace officer's employing law enforcement unit for disciplinary reasons.

(b)(1) When the council finds that any person is unqualified to be granted a certificate or finds that any person should be disciplined pursuant to subsection (a) of this Code section, the council may take any one or more of the following actions:

(A) Refuse to grant a certificate to an applicant;

(B) Administer a public or private reprimand, provided that a private reprimand shall not be disclosed to any person except the peace officer;

(C) Suspend any certificate for a definite period;

(D) Limit or restrict any certificate;

(E) Revoke any certificate; or

(F) Condition the penalty, or withhold formal disposition, upon the peace officer's completing such care, counseling, or treatment, as directed by the council.

(2) In addition to and in conjunction with the foregoing actions, the council may make a finding adverse to the applicant or peace officer but withhold imposition of judgment and penalty or it may impose the judgment and penalty but suspend enforcement thereof and place the peace officer on probation, which probation may be vacated upon noncompliance with such reasonable terms as the council may impose.

(c) In its discretion, the council may restore and reissue a certificate issued under this chapter or any antecedent law to a peace officer and, as a condition thereof, may impose any disciplinary or corrective measure provided in this chapter.
