Conn. Gen. Stat. § 22a-7a: Bond on appeal from final decision.

In any appeal from a final decision made by the Commissioner of Energy and Environmental Protection in accordance with the provisions of sections 22a-123, 22a-174, 22a-181, 22a-428, 22a-430 and 22a-431, subsection (c) of section 22a-449 and sections 22a-461 and 22a-471, the court, if it finds that there is probable cause to believe that a violation exists, may require the filing of a surety bond or other security with the court prior to granting a stay of such decision. In setting the amount of any such bond or other security, the court shall consider the cost of compliance with such decision and the potential harm to the public from the actions of the aggrieved party pending the final disposition of the appeal.
