Conn. Gen. Stat. § 13a-62: Application to Superior Court for relief.

Any person aggrieved by the doings of the selectmen in laying out a highway may, within one hundred twenty days after the survey thereof has been accepted by the town, apply to the superior court for the judicial district in which such town is located for relief, causing such selectmen to be cited to show cause why such relief should not be granted. Such application shall be heard and determined by a committee of three disinterested persons to be appointed by the court. If such committee finds that such highway is not of common convenience and necessity, said court shall set aside such layout, and, if said court sets aside such layout, the costs shall be paid by the town; but, if such committee finds that such highway is of common convenience and necessity, the application shall be dismissed with costs. The report of such committee may be set aside by the court for any irregularity or improper conduct on its part. Proceedings under this section shall not prevent or delay the opening or occupation of such highway.
