Notice to produce governs admissibility of secondary evidence, subject to listed exceptions and Court discretion to dispense. Secondary evidence of documents referred to in clause (a) of section 60 requires prior service of the statutory or, if none prescribed, a Court-reasonable notice to produce on the party in possession or their representative; admissibility is conditioned on this prior notice. Specified exceptions dispense with notice where the document is itself a notice, production is obviously expected, the original was obtained by fraud or force, the original is in Court, the adverse party admits loss, or the custodian is beyond Court process, and the Court may otherwise dispense with notice.
