That the pre-deposit is required to be made, subject to the appellate tribunal's authority to waive or reduce the amount, by a person seeking to prefer an appeal from an order adjudging such person to be indebted to a bank or the like is evident. The pre-deposit may also be required to be made, subject again to the appellate tribunal's power to waive or reduce the amount, if an appeal is preferred by a person adjudged to be indebted to a bank or the like even if the order sought to be appealed against may not be the order of adjudication of the indebtedness of the would-be appellant. It is possible that a certificate (the equivalent of a decree) is passed by a Debts Recovery Tribunal against a respondent to a petition under Section 19 of the Act on the basis of an admission in recognition of the principle embodied in Order XII Rule 6 of the Code. It is possible that the certificate-debtor does not prefer an appeal from the certificate passed on admission, but prefers an appeal from an interlocutory order at a subsequent stage. Section 21 of the Act describes the legal character of the person who is the would-be appellant and not the nature of the order that is sought to be appealed against. The operative words in Section 21 of the Act are "by any person from whom the amount of debt is due."

If such person were not to prefer an appeal from the order finding him indebted to a bank or the like, but seeks to prefer an appeal from a subsequent interlocutory order, such person continues to be a person from whom an amount of debt has been adjudged to be due. Unless such person has preferred an appeal from the order finding him indebted to a bank or the like and has deposited the requisite sum, subject to the waiver or reduction of the amount as directed by the appellate tribunal, the requirement of the pre-deposit will continue to operate on the person even if he were to prefer an appeal from a subsequent order and notwithstanding such subsequent
