If, on scrutiny, the appeal or petition or application or document is found to be defective, such document shall, after notice to the party, to returned for compliance and if there is a failure to comply within seven days from the date of return, the same shall be placed before the Registrar who may pass appropriate orders. The Registrar may for sufficient cause return the said document for rectification or amendment to the party filing the same, and for this purpose may allow to the party concerned such reasonable time as he may consider necessary or extend the time for compliance. Where the party fails to take any step for the removal of the defect within the time fixed for the same, the Registrar may, for reasons to be recorded in writing, decline to register the pleading or document.
