13. Summary Rejection

(1) If the memorandum of appeal omits to state any of the particulars specified in Form X as required under rule 12 or is not accompanied with the order against which it is made or a duly authenticated copy thereof, the appeal may be summarily rejected:

              Provided that no appeal shall be summarily rejected under this sub-rule unless the appellant or the applicant is given a reasonable opportunity to amend the memorandum of appeal.

             (2)  The appeal may also be summarily rejected on grounds other than those specified in sub-rule (1), which the Appellate Authority may consider sufficient and which shall be reduced to writing by the Appellate Authority:

              Provided that before an order summarily rejecting an appeal under this sub-rule is passed, the appellant concerned shall be given a reasonable opportunity of being heard.

             (3) If within thirty days from the date on which an appeal is summarily rejected under sub-rule (1) or (2), the appellant or applicant makes an application to the, Appellate Authority for setting aside the order of summary rejection and satisfied it that the notice under the proviso to sub-rule (1) to amend the memorandum of appeal, or of hearing under the proviso to sub-rule (2) was not duly served on him, or that he was prevented by sufficient cause from amending the memorandum of appeal or from appearing when the appeal was called on for hearing, the said Authority shall make an order setting aside the summary rejection and restore the appeal to its file.
