Revocation of probate-even though learned Single Judge had discretion to issue citation or not but in the facts of the present case a citation ought to have been issued in exercise of discretion conferred under Section 283 of the Succession Act and the probate granted without issuance of such citation in the facts of the present case deserves to be revoked and learned Single Judge and the Division Bench committed error in rejecting the application for revocation filed by the appellant.
