Conn. Gen. Stat. § 31-243
Jurisdiction over benefits shall be continuous but the initiating of a valid appeal under section 31-242 or the pendency of valid appellate proceedings under section 31-249 shall, if the appellate tribunal has taken jurisdiction, stay any proceeding hereunder, but only in respect to the same period and the same parties, but shall not cause the cessation of payment of benefits as provided by section 31-242. Where the appellate tribunal has not taken jurisdiction, upon his own initiative, or upon application of any party in interest, the administrator, or the examiner designated by him, may, at any time within six months after the date of the original decision, or within such other time limits as may be applicable under section 31-273, review an award of benefits or the denial of a claim therefor, in accordance with the procedure prescribed in respect to claims, and may issue a new decision, which may award, terminate, continue, increase or decrease such benefits. Such new decision shall be appealable under the provisions of section 31-242 within the time prescribed in section 31-241, and where the claimant has been free from fault, a redetermination or new decision shall not affect benefits paid under a prior order. Any decision to review an award of benefits or the denial of a claim under this section shall be solely within the discretion of the administrator and shall not be appealable under the provisions of section 31-242.
