After the determination by the Crown Court of an appeal from a magistrates' court the decision appealed against as confirmed or varied by the Crown Court, or any decision of the Crown Court substituted for the decision appealed against, may, without prejudice to the powers of the Crown Court to enforce the decision, be enforced—
(a) by the issue by the court by which the decision appealed against was given of any process that it could have issued if it had decided the case as the Crown Court decided it;
(b) so far as the nature of any process already issued to enforce the decision appealed against permits, by that process;
and the decision of the Crown Court shall have effect as if it had been made by the magistrates' court against whose decision the appeal is brought.
