Conn. Gen. Stat. § 31-297
If an employer and his injured employee, or his legal representative, as the case may be, fail to reach an agreement in regard to compensation under the provisions of this chapter, either party may notify the administrative law judge of the failure. Upon such notice, or upon the knowledge that an agreement has not been reached in a case in which a right to compensation may exist, the administrative law judge shall schedule an early hearing upon the matter, giving both parties notice of time and place not less than ten days prior to the scheduled date; provided the commissioner may, on finding an emergency to exist, give such notice as he finds reasonable under the circumstances. If no agreement has been reached within sixty days after the date notice of claim for compensation was received by the administrative law judge, as provided in section 31-294c, a formal hearing shall be scheduled on the claim and held within thirty days after the end of the sixty-day period, except that if an earlier hearing date has previously been scheduled, the earlier date shall prevail. Hearings shall be held, if practicable, in the town in which the injured employee resides; or, if it is not practicable to hold a hearing in the town, in any other convenient place that the administrative law judge may prescribe. Sufficient notice of the hearing may be given to the parties in interest by a brief written statement in ordinary terms of the date, place and nature of the injury upon which the claim for compensation is based.
