Conn. Gen. Stat. § 16-8b

Whenever a labor dispute at a public service company, as defined in section 16-1 , results in a work stoppage for a period of more than seven days, the Public Utilities Regulatory Authority shall initiate a proceeding not later than thirty days after the termination of the labor dispute to determine whether the public service company, as a result of such work stoppage, earned unreasonable profits and whether the quality of service to the customers of such public service company was impaired. The authority may issue such remedial orders as may be necessary to protect ratepayers including, but not limited to, refunds or other adjustments.
