(2) The defendant may appeal even from a final judgment entered in the District Court though imposition or execution of sentence has been suspended.

(c) Notwithstanding any other provision of law, an appeal taken under subsection (b)(1)(ii) of this section shall be:

(1) To the circuit court solely for the purpose of reviewing the judgment of the District Court; and

(2) Heard on the record made in the District Court.

(d) (1) A defendant who has been found guilty of a municipal infraction, as described in § 6–102 of the Local Government Article or a Code violation under § 10–119 of the Criminal Law Article, may appeal from the final judgment entered in the District Court.

(2) The costs and procedures for taking the appeal shall be as provided for appeals from criminal cases in the District Court.

(3) Except, however, as provided in subsection (f) of this section, the appellate court shall docket and hear the appeal as a civil appeal from the District Court.

(e) (1) Except as provided in paragraph (2) of this subsection, an appeal shall be taken by filing an order for appeal with the clerk of the District Court within 30 days from the date of the final judgment from which appealed.

(2) If the final judgment was entered in a case filed under § 8–332, § 8–401, § 8–402, § 14–109, or § 14–120 of the Real Property Article, the order for appeal shall be filed within the time prescribed by the particular section.
