The ethics committee may resolve pending complaints by issuance of formal advisory letters informing licensees of their duties under the Act or this chapter, and whether the conduct or omission complained of appears to violate such duties. Such advisory letters may be introduced as evidence in any subsequent disciplinary action involving acts or omissions after receipt of the advisory letters. The ethics committee or executive director, as appropriate, may also issue informal reminders to licensees regarding compliance with minor licensing matters. The licensee is not entitled to a hearing on the matters set forth in formal advisory letters or informal reminders, but may submit a written response to be included with such letters in the licensing record.
