“The principle of doctrine of restitution is that on the reversal of a decree, the law imposes an obligation on the party to the suit who received the benefit of the decree to make restitution to the other party for what he has lost. ”
The Supreme Court observed that the provisions of Section 144 of the Code of Civil Procedure will not be attracted when there is no variation or reversal of a decree or order.
In appeal, the bench comprising Justice Mohan M. Shantanagoudar and Justice Ajay Rastogi explained the scope of Section 144 as follows:
It clearly transpires that Section 144 applies to a situation where a decree or order is varied or reversed in appeal, revision or any other proceeding or is set aside or modified in any suit instituted for the purpose. The principle of doctrine of restitution is that on the reversal of a decree, the law imposes an obligation on the party to the suit who received the benefit of the decree to make restitution to the other party for what he has lost. This obligation arises automatically on the reversal or modification of the decree and necessarily carries with it the right to restitution of all that has been done under the decree which has been set aside or an order is varied or reversed and the Court in making restitution is bound to restore the parties, so far as they can be restored, to the same position as they were in at the time when the Court by its action had displaced them.
