In law, venire facias de novo (Latin for "may you cause to come anew"), sometimes abbreviated to venire facias ("may you cause to come") is a writ issued by an officer of the court summoning prospective jurors, which the court uses when there has been some impropriety or irregularity in the jury, or where the verdict is so imperfect or ambiguous that no judgment can be given upon it, and so a new jury must be chosen.
See the 1817 decision of the U.S. Supreme Court in Laidlaw v. Organ (15 U.S. 178): "...the judgment must be reversed, and the cause remanded to the district court of Louisiana, with direction to award a venire facire de novo" (John Marshall).
