Gujarat High Court Civil Manual (subordinate court practice), 1960
Under clause (c) of section 30 of the Code, a Court may order any fact to be proved by affidavit. This is a power which may well be used to secure formal proof of facts. It is desirable to make full use of the provisions of Order XIX for the proof of simple or incontrovertible facts. Whenever a fact is allowed to be proved by an affidavit, an order should invariably be passed by the Court.
