Defect correction in appeals: Registrar may return filings, permit limited extensions, or refer persistent defects to the Bench for decision. Procedural rules require that defective appeals, applications or documents be returned for rectification after notice; if defects are not remedied within the specified short compliance period the matter is placed before the Registrar who may allow amendments, grant a limited extension, decline registration for written reasons, or, after personal hearing and persistent defects, list the matter before the Bench which may accept or reject registration.
