Res judicata in land acquisition bars reopening final writ directions on equitable interest once complied with and unchallenged.

A final writ direction granting equitable interest at 12% per annum from the date possession was taken, once acted upon and incorporated into the acquisition award, bound the parties in later land acquisition proceedings. The principle of res judicata applies to subsequent stages of the same matter and to writ proceedings, so the entitlement could not be reopened after the earlier order had attained finality. An appellate court under Section 54 of the Land Acquisition Act, 1894, could not restrict interest to a later notification date, nor could the High Court ignore an operative writ direction or decide outside the pleadings once the award had been implemented and left unchallenged.

Issues: (i) whether the earlier writ directions granting equitable interest at 12% per annum on the acquired land had attained finality and bound the parties in the subsequent land acquisition proceedings; (ii) whether the appellate court in land acquisition proceedings could restrict interest to a later date contrary to the earlier binding writ directions and the award made in implementation thereof.

Issue (i): whether the earlier writ directions granting equitable interest at 12% per annum on the acquired land had attained finality and bound the parties in the subsequent land acquisition proceedings.

Analysis: A writ of mandamus had been issued directing completion of acquisition and payment of equitable interest from the date possession was taken. That direction was acted upon and the acquisition award itself incorporated the benefit. Once the earlier judgment in writ proceedings had attained finality, the same parties could not reopen a matter that was concluded between them. The principle of res judicata applies not only to separate subsequent proceedings but also to later stages of the same proceedings, and it extends to writ proceedings as well.

Conclusion: The earlier writ directions were binding and could not be contradicted in the later proceedings.

Issue (ii): whether the appellate court in land acquisition proceedings could restrict interest to a later date contrary to the earlier binding writ directions and the award made in implementation thereof.

Analysis: The appellate court under Section 54 of the Land Acquisition Act, 1894, could not travel beyond what had already become final, especially when the State had not challenged the earlier writ order or the award made in its implementation. The High Court also could not introduce a new case outside the pleadings or ignore an operative writ direction that continued to bind the parties. Once the directions had been complied with and the land acquisition award had attained finality, the matter could not be reopened to curtail the equitable interest granted from the date of possession.

Conclusion: The restriction of interest to the later notification date was unsustainable and was set aside.

Final Conclusion: The appeals succeeded, the High Court's judgment was overturned, and the Reference Court's award was restored.

Ratio Decidendi: A final writ direction, once acted upon and not challenged, operates with binding finality under res judicata in subsequent stages of the same matter, and a later court cannot vary that concluded entitlement or decide a case on a ground outside the pleadings.
