However, under the third proviso to the sub-section, the Appellate Tribunal has the power to reduce the amount, for the reasons to be recorded in writing, to not less than twenty-five per cent of the debt, referred to in the second proviso.

Unless the borrower makes, with the Appellate Tribunal, a pre-deposit of fifty per cent of the debt due from him or determined, an appeal under the said provision cannot be entertained by the Appellate Tribunal. The language of the said proviso is clear and admits of no ambiguity. It is well-settled that when a Statute confers a right of appeal, while granting the right, the Legislature can impose conditions for the exercise of such right, so long as the conditions are not so onerous as to amount to unreasonable restrictions, rendering the right almost illusory. Bearing in mind the object of the Act, the conditions hedged in the said proviso cannot be said to be onerous.
