a. When the appeal has been perfected and the time for filing the appellee's memorandum has expired, the trial court shall send the record on appeal and memoranda to the Superior Court within 30 calendar days.

b. If a sufficient record of the hearing or trial on which the appeal is based cannot be made available, the trial court shall notify the parties and summarily transfer the entire file to the Superior Court for a trial de novo. Where the entire case is transferred under this subparagraph, no appellate memoranda shall be required. Upon receipt of the file, the Superior Court shall notify the parties with instructions as to further proceedings.
