Gujarat High Court Civil Manual (subordinate court practice), 1960
The theory of the suit is that at the beginning the defendant knows nothing about it and therefore nothing should be done without his first having notice of it. Theory of execution is that the loser in the suit (the judgment-debtor) knows all about the decree and anticipates that it will be executed against him. Therefore if the person benefiting by decree (the judgment-creditor) applies to the Court with reasonable promptitude, he will usually obtain the Court's assistance in execution without any notice being required in the first instance to be given to the judgment-debtor.
