Within twenty-five (25) days of the filing of the petition, the agency shall decide whether to reconsider the final decision. The failure of the agency to make that determination within twenty-five (25) days of such filing shall constitute a denial of the petition. Within forty (40) days of the personal delivery or mailing of the final decision, the agency, regardless of whether a petition for reconsideration has been filed, may decide to reconsider a final decision. If the agency decides to reconsider a final decision, pursuant to subdivisions (1), (2) or (3) of this subsection, the agency shall proceed in a reasonable time to conduct such additional proceedings as may be necessary to render a decision modifying, affirming or reversing the final decision. Any such additional proceedings shall be conducted in accordance with Sections 17-603 and 17-604 of the Connecticut General Statutes and these regulations.
