Conn. Gen. Stat. § 31-342

In any such hearing, the administrative law judge having jurisdiction may make his award directly against such employer, insurer or both, except that, when there is doubt as to the respective liability of two or more insurers, he shall make his award directly against such insurers; and such awards shall be enforceable against the insurer in all respects as provided by law for enforcing awards against an employer, and the proceedings on hearing, finding, award, appeal and execution shall be in all respects similar to that provided by law as between employer and employee.
