Conn. Gen. Stat. § 52-216c: Failure to call a witness. Jury instruction prohibited; argument by counsel permitted.

No court in the trial of a civil action may instruct the jury that an inference unfavorable to any party's cause may be drawn from the failure of any party to call a witness at such trial. However, counsel for any party to the action shall be entitled to argue to the trier of fact during closing arguments, except where prohibited by section 52-174, that the jury should draw an adverse inference from another party's failure to call a witness who has been proven to be available to testify.
