A person aggrieved by an overcrowding notice may, within 21 days after the date of service of the notice, appeal to the county court, which may make such order either confirming, quashing or varying the notice as it thinks fit.
If an appeal is brought the notice does not become operative until—
a decision on the appeal confirming the order (with or without variation) is given and the period within which an appeal to the Court of Appeal may be brought expires without any such appeal having been brought, or
if a further appeal to the Court of Appeal is brought, a decision on that appeal is given confirming the order (with or without variation);
and for this purpose the withdrawal of an appeal has the same effect as a decision confirming the notice or decision appealed against.
