(a) Before rendering a decision in a contested case, the Director shall consider the entire record or any portion of the record to which the parties have stipulated. If a recommended decision is rendered, all parties shall be afforded a reasonable opportunity to file exceptions thereto which shall become a part of the record. As a matter of right, each party shall be permitted to file a brief with respect to the recommended decision with the Division and oral argument may be allowed at the discretion of the Director.
(b) A final decision or order adverse to a party in a contested case shall be in writing and shall be served immediately upon each party or upon his attorney of record. The final decision shall contain findings of fact and conclusions of law separately stated. The findings of fact shall be based exclusively on the evidence and matters officially noticed. If the findings of fact are set forth in statutory language, they shall include, also, a concise and explicit statement of the underlying facts supporting the findings. The Director shall serve each party with a copy of his/her decision and findings of fact and conclusions of law.
