(1) Where and in so far as a decree is for the payment of money, the Court may, in the decree, order interest at such rate as the Court deems reasonable to be paid on the principal sum adjudged, from the date of the suit to the date of the decree, in addition to any interest adjudged on such principal sum for any period prior to the institution of the suit, with further interest at such rate as the Court deems reasonable on the aggregate sum so adjudged, from the date of the decree to the date of payment, or to such earlier date as the Court thinks fit.
(2) Where such a decree is silent with respect to the payment of further interest on such aggregate sum as aforesaid from the date of the decree to the date of payment or other earlier date, the Court shall be deemed to have refused such interest, and a separate suit therefor shall not lie.
