Connecticut General Statutes Title 54. Criminal Procedure § 54-33f. Motion for return of unlawfully seized property and suppression as evidence

(a) A person aggrieved by search and seizure may move the court which has jurisdiction of such person's case or, if such jurisdiction has not yet been invoked, then the court which issued the warrant, or the court in which such person's case is pending, for the return of the property and to suppress for use as evidence anything so obtained on the ground that: (1) The property was seized without a warrant, or (2) the warrant is insufficient on its face, or (3) the property seized is not that described in the warrant, or (4) there was not probable cause for believing the existence of the grounds on which the warrant was issued, or (5) the warrant was illegally executed. In no case may the judge or judge trial referee who signed the warrant preside at the hearing on the motion.

(b) The motion shall be made before trial or hearing unless opportunity therefor did not exist or the defendant was not aware of the grounds for the motion, but the court in its discretion may entertain the motion at the trial or hearing.

(c) The court shall receive evidence on any issue of fact necessary to the decision of the motion. If the motion is granted, the property shall be restored unless otherwise subject to lawful detention and it shall not be admissible in evidence at any hearing or trial.
