Conn. Gen. Stat. § 52-216: Deciding questions of law and of fact.

The court shall decide all issues of law and all questions of law arising in the trial of any issue of fact; and, in committing the action to the jury, shall direct them to find accordingly. The court shall submit all questions of fact to the jury, with such observations on the evidence, for their information, as it thinks proper, without any direction as to how they shall find the facts. After the action has been committed to the jury, no pleas, arguments or evidence may be received before the verdict is returned into court and recorded.
