“ 18. From the aforesaid rulings the following principles can be summarised. (a) Before 1929, it was obligatory for the Court to direct the contract rate of interest to be paid by the mortgagor on the sum adjudged in the preliminary decree, from the date of suit till the date fixed for payment as per Order 34 Rule 2(c)(i) or Order 34 Rule 4(1) or Order 34 Rule 7(c)(i), respectively in suits for foreclosure, sale or redemption. (b) But after the 1929 Amendment, because of the words used in the main part of Order 34 Rule 11, namely that “the Court may order payment of interest” it is no longer obligatory on the part of the Court while passing preliminary decree to require payment at the contract rate of interest from date of suit till the date fixed in the preliminary decree for payment of the amount. It has been so held in Jaigobind case by the Privy Council and by this Court in S.P. Majoo case that the new provision gives a certain amount of discretion to the Court so far as pendente lite interest is concerned and subsequent interest is concerned. (c) It is no longer obligatory to award the contractual rate after date of suit and up to the date fixed for redemption as above stated even though there was no question of the contractual rate being penal, excessive or substantially unfair within the meaning of the Usurious Loans Act, 1918. (d) Even if the Court otherwise wants to award interest, the position after the 1929 and 1956 Amendments is that the Court has discretion to fix interest from date of suit under Order 34 Rule 11(a)(i) up to date fixed for payment in the preliminary decree, the same rate agreed in the contract, or, if no rate is so fixed, such rate as the Court deems reasonable — on the principal amount found or declared due on the mortgagor is concerned. (e) The Court has also power to award from the date of suit under Order 34 Rule 11(a)(iii) a rate of interest on costs, charges and expenses as per the contract rate or failing such rate, at a rate not exceeding 6%. This is the position of the discretionary power of the Court, from the date of suit up to the date fixed in the preliminary decree as the date for payment. (f) Again under Order 34 Rule 11(b) so far as the period after the date fixed for payment is concerned, the Court, even if it wants to exercise its discretion to award interest up to date of realisation or actual payment, on the aggregate sums specified in clause (a) of Order 34 Rule 11, could award interest at such rate as it deemed reasonable”.
