An order of venire de novo may follow the finding that a trial was a nullity to require the matter to be heard again. It is abbreviation of a longer Latin phrase which directed the sheriff to cause new lawful jurors to try a case afresh. The central issue in this application is whether it is available to attack a summary trial in the Magistrates' Court, rather than a trial on indictment in Crown Court.
... the Criminal Division of Court of Appeal has power to order a venire de novo only in the circumstances in which its predecessor, the Court of Criminal Appeal, could do so pursuant to powers conferred on it by the Criminal Appeal Act 1907. Such power did not include a power to declare a summary trial a nullity, or quash a conviction recorded in such proceedings, and remit the matter for retrial. Venire de novo was, and is, concerned only with trials on indictment, and with fundamental irregularities which render such a trial a nullity.
