have been given if delivered or mailed to the license-holder or
applicant at the address given in the license or application for
license. Any person claiming to be aggrieved by the action of
the Commissioner or local licensing authority in refusing to
grant him a license or in revoking a license previously granted
to him, may, not later than the thirtieth day after the day of
delivery or mailing of the notice, as aforesaid, appeal to the
Circuit Court of any County, sitting in equity, or the Circuit
Court of Baltimore City, in which the office of the Commis-
sioner or of the local licensing authority, as the case may be,
is situated. All such appeals shall be initiated by a petition
setting forth concisely the particulars in which the action of
the Commissioner or local licensing authority is claimed to be
unlawful or erroneous. The hearing on petition shall be
de novo on both the law and the facts and any party may in-
troduce testimony or other evidence. If the Court finds the
action of the Commissioner or local licensing authority to be
unlawful or contrary to the substantial weight of the evidence,
it shall remand the case for further proceedings in accordance
with its opinion or order; otherwise, the action of the Commis-
sioner or local licensing authority shall be affirmed. From the
final decision of the Circuit Court, any party to the case may
take an appeal to the Court of Appeals in the same manner as
in other equity cases, but not later than the tenth day after
the date of the order appealed from; and the Court of Appeals
shall promptly hear and determine such appeal.
