Conn. Gen. Stat. § 7-456: Deductions from wages.

The legislative body of each municipal member of the system shall direct the treasurer or other financial officer of the municipality to make deductions from the wages of its employees as required by section 7-453. The total amount of such deductions and an equal amount appropriated by the municipality shall be forwarded to the commission within the time fixed by the commission; and if any municipality fails to make such payment within the time specified, the commission shall notify the Comptroller of such default and he shall withhold from such municipality the whole or any part of any sum due from the state until such payment is made. The commission is authorized to bring a civil action, in the name of the state, against any municipality so in default.
