Lekh Raj (Dead) Through L.Rs. & Ors. v. Ranjit Singh & Ors.
Background
In 1965, an Additional District Judge in Ambala decreed a long-running civil suit in favour of the respondents (plaintiffs), recognising certain customary inheritance rights over agricultural land and this decree became final since it was never appealed further. Decades later, when the respondents sought to execute that decree, the appellants (the original defendants' legal heirs) raised several objections before the Executing Court, the first appellate court, and the High Court, all of which were rejected, and by the time the matter reached the Supreme Court, the appellants had dropped all those earlier objections and raised an entirely new argument: that a 1973 amendment to the Punjab Custom (Power to Contest) Act, 1920 had retrospectively wiped out the customary rights underlying the 1965 decree, making it a legal "nullity."
Decision Breakdown
The Supreme Court rejected this new argument on multiple independent grounds: it had never been raised at any of the three earlier stages of litigation and could not be raised for the first time on appeal; in any event, the suit and appeal had already reached finality in 1965, years before the 1973 amendment, so the amendment (even though held retroactive in two earlier Supreme Court decisions) could not unsettle rights that had already crystallised; and separately, the 1973 amendment applied only to the State of Punjab, not Haryana, where this case arose. The Court also independently confirmed that the lower courts had correctly held that an executing court cannot "go behind the decree" and re-examine factual objections that belonged in the original trial. The appeal was accordingly dismissed.
Lesson Learnt
Once a court decree has become final and the underlying dispute has reached closure, a later change in the law generally cannot be used to reopen or invalidate it, and separately, a court executing a decree is not the right forum to re-litigate factual disputes that should have been raised during the original trial.
