Gujarat High Court Criminal Manual (subordinate court practice), 1977
Several persons complaining of one order or judgment in a criminal case affecting them all may join in one appeal or application for revision, and one copy of the judgment or order complained of shall be sufficient. The appellate Court may, however, require separate petitions to be made by petitioners whose cases are, in its opinion, conflicting. Where a joint petition is allowed, one Court-fee and Vakalatnama shall be sufficient.
