The Administration, any aggrieved person, or any officer or agency of the political subdivision may appeal from a decision of the board of appeals to a court of competent jurisdiction. If, at the hearing, it appears to the court that testimony is necessary for the proper disposition of the matter, the court may take evidence or appoint a commissioner to take the evidence that the court directs and report to the court with his findings of fact and conclusions of law. These findings and conclusions constitute a part of the proceedings on which the determination of the court shall be made. The court may: Reverse, affirm, or modify the decision brought up for review; and If necessary, order further proceedings by the board of appeals. It is not necessary to join the board of appeals as a party. An appeal may be taken to the Appellate Court of Maryland from any decision of the court of record reviewing the decision of the board of appeals.
