If the appellant's brief has not been filed in a civil case within the time allowed by Rule 4-4, the Court may dismiss the appeal and affirm the judgment or decree at cost to the appellant. When the appellee has failed to appear and file a brief, the Court may, when the case is called for submission, proceed and give judgment according to the requirements of the case.
