Conn. Gen. Stat. § 54-96b
Any person appealing from any judgment of the superior court under which judgment such person may be committed to a community correctional center may, at any time before the hearing in the Supreme Court or Appellate Court, notify the Superior Court that such appeal is withdrawn, and, if such person is in a community correctional center in default of bail awaiting trial upon such appeal, the court shall forthwith forward a mittimus to the Community Correctional Center Administrator, and the term of such sentence shall run from the date of such notice, provided such term shall not run concurrently with any other sentence or term imposed upon such person unless so directed by such court. If any person taking such appeal is at large, such person shall forthwith surrender himself to the court from which such appeal was taken and such court shall issue a mittimus in the same manner as though no appeal had been taken. Upon the issuance of such mittimus, such appeal shall be vacated and the judgment shall be in force. In any case in which the judgment from which an appeal has been taken includes a community correctional center sentence and a fine, such appeal may be vacated upon compliance with the provisions of section 54-96a and of this section, and thereupon such judgment shall be in effect.
