(a)(1) Any person, including any lessee of real property whose lease has been recorded as provided in section 47-19 and who is bound under the terms of such person's lease to pay real property taxes, claiming to be aggrieved by the action of the board of tax review or the board of assessment appeals, as the case may be, in any town or city may make application, not later than two months after the date of the mailing of notice of such action, in the nature of an appeal therefrom to the superior court for the judicial district in which such town or city is situated, which shall be accompanied by a citation to such town or city to appear before such court. Such citation shall be signed by the same authority and such appeal shall be returnable at the same time and served and returned in the same manner as is required in case of a summons in a civil action. The authority issuing the citation shall take from the applicant a bond or recognizance to such town or city, with surety, to prosecute the application to effect and to comply with and conform to the orders and decrees of the court in the premises. Any such application shall be a preferred case, to be heard, unless good cause appears to the contrary, at the first session, by the court or by a committee appointed by the court. The pendency of such application shall not suspend an action by such town or city to collect not more than seventy-five per cent of the tax so assessed or not more than ninety per cent of such tax with respect to any real property for which the assessed value is five hundred thousand dollars or more, and upon which such appeal is taken. If, during the pendency of such appeal, a new assessment year begins, the applicant may amend the application as to any matter therein, including an appeal for such new year, that is affected by the inception of such new year and such applicant need not appear before the board of tax review or board of assessment appeals, as the case may be, to make such amendment effective.

1. (2) For any application made on or after July 1, 2022, under subdivision (1) of this subsection, if the assessed value of the real property that is the subject of such application is one million dollars or more and the application concerns the valuation of such real property, the applicant shall file with the court, not later than one hundred twenty days after making such application, an appraisal of the real property that is the subject of the application. Such appraisal shall be completed by an individual or a company licensed to perform real estate appraisals in the state. The court may extend the one-hundred-twenty-day period for good cause. If such appraisal is not timely filed, the court may dismiss the application, except that for any application made on or after July 1, 2022, but prior to July 1, 2024, that was dismissed due to such appraisal having been submitted to the assessor of the town or city in which such real property is situated rather than the court, the applicant may make another application with the court, provided the applicant (A) had provided notice to the court of such submission to the assessor, and (B) makes such application not later than September 1, 2024.
2. (b) The court shall have power to grant such relief as to justice and equity appertains, upon such terms and in such manner and form as appear equitable, and, if the application appears to have been made without probable cause, may tax double or triple costs, as the case appears to demand; and, upon all such applications, costs may be taxed at the discretion of the court. If the assessment made by the board of tax review or board of assessment appeals, as the case may be, is reduced by the court, the applicant shall be reimbursed by the town or city for any overpayment of taxes, together with interest and any costs awarded by the court, or, at the applicant's option, shall be granted a tax credit for such overpayment, interest and any costs awarded by the court. Upon motion, the court shall, in event of such overpayment, enter judgment in favor of such applicant and against such city or town for the whole amount of such overpayment, less any lien recording fees incurred under sections 7-34a and 12-176, together with interest and any costs awarded by the court. The amount to which the assessment is so reduced shall be the assessed value of such property on the grand lists for succeeding years until the tax assessor finds that the value of the applicant's property has increased or decreased.
