Whenever the board receives evidence that a person practicing before the board is guilty of unethical or fraudulent conduct, such person shall be cited by certified mail to appear before the board in person to show cause why he or she should not be barred from practicing before the board because of such conduct. In all such cases, the board's citation shall contain a detailed description of charges to be considered at such hearing and a reasonable time to secure and prepare evidence shall be given any such person as cited (November 14, 1955) (Rev. 1973).
