A verdict is a written declaration by a jury of its decision, comprehending the whole or all the issues submitted to the jury, and shall be either a general or special verdict, as directed, which shall be signed by the presiding juror of the jury.
A general verdict is one whereby the jury pronounces generally in favor of one or more parties to the suit upon all or any of the issues submitted to it. A special verdict is one wherein the jury finds the facts only on issues made up and submitted to them under the direction of the court. A special verdict shall, as between the parties, be conclusive as to the facts found.
