Legal Commentary & Landmark Judgments: Section 37
Section 37 defines the expression 'court which passed a decree' for the purposes of execution, ensuring that decrees remain executable even if the original trial court has been abolished or its territorial jurisdiction altered.
If the territorial area where the disputed land is situated was transferred to a newly created civil court after the decree was passed, file your execution petition directly in the new court under Section 37(b).
