Retrospective amendment and res judicata: later tenancy provision could not reopen a finally decided claim.

A later amendment cannot reopen a tenancy claim that has already been finally rejected unless it retrospectively removes the statutory foundation of the earlier determination. The Court noted that the prior rejection of deemed tenancy under the Kerala Land Reforms Act had attained finality and rested on the prohibition against creating tenancies after 1 April 1964. Section 6C, though containing a non obstante clause, was not given retrospective effect and therefore did not displace the binding earlier decision. On that basis, the appellant could not re-agitate the same issue in execution proceedings, and res judicata continued to apply.

Issues: Whether the appellant could invoke Section 6C of the Kerala Land Reforms Act, 1963 to re-agitate his claim of deemed tenancy after that claim had already been finally rejected in earlier proceedings.

Analysis: The earlier adjudication on the appellant's tenancy claim had attained finality and was based on Section 74 of the Kerala Land Reforms Act, 1963, which prohibited creation of tenancies after 1 April 1964. Section 6C, though introduced later with a non obstante clause, was not given retrospective effect so as to remove the legal foundation of the earlier final decisions. A subsequent legislative provision can displace a binding judgment only if it retrospectively alters or removes the substratum on which that judgment rests. In the absence of such retrospective validation, the earlier decision remains binding between the parties and the same issue cannot be reopened in execution proceedings.

Conclusion: The appellant's claim under Section 6C was barred by res judicata, and the appeal failed.

Ratio Decidendi: A final judicial determination cannot be reopened by a later amendment unless the amendment retrospectively removes the statutory foundation of that determination; otherwise, res judicata continues to apply.
