(1) Where the jury in civil proceedings have retired for more than 4 hours,
the court in which the proceedings are being tried may discharge them if it
finds, after examination on oath of one or more of them, that they are not
likely to agree on either a unanimous verdict or a verdict under section 57.
(3) Where a jury is discharged under this section, the proceedings may,
without any new process for that purpose, be set down for trial either at the
same or any subsequent sittings, as the court may order.
