Immutability of Judgments: When Final Decisions Stand Firm

The principle of immutability of judgments ensures that once a decision becomes final, it can no longer be modified, even if the modification is meant to correct an error. This doctrine is fundamental to the orderly administration of justice. In Land Bank of the Philippines v. Hababag, Sr. (G.R. No. 172352, June 8, 2016), the Supreme Court reaffirmed this principle, denying the Land Bank's motion for reconsideration and clarifying the computation of legal interest on unpaid just compensation.

The Facts

The case involved 69.3857 hectares of land covered by the Comprehensive Agrarian Reform Program under Republic Act No. 6657. The Department of Agrarian Reform fixed the initial valuation, and Land Bank paid the landowners P1,237,850.00. Dissatisfied, the landowners filed a case for just compensation with the Regional Trial Court of Sorsogon City.

The RTC fixed a higher valuation using the Income Productivity Approach. On appeal, the Court of Appeals reversed, applying the DAR formula and setting just compensation at P2,398,487.24. The CA also imposed legal interest on the unpaid balance.

The Supreme Court affirmed the CA's valuation in its September 16, 2015 Decision, but modified the interest rate. Land Bank then filed a motion for reconsideration, arguing it should not pay interest because it promptly deposited the initial valuation.

The Issue

The central issue was whether Land Bank could escape liability for legal interest on the unpaid balance of just compensation. Land Bank also sought clarification on the date from which interest should be computed.

The Ruling

The Supreme Court denied Land Bank's motion with finality. Citing Apo Fruits Corporation v. Land Bank (647 Phil. 251 [2010]), the Court held that the substantiality of initial payments is not the determining factor for imposing interest. Nothing less than full payment of just compensation satisfies the constitutional requirement.

The Court explained that interest runs as a matter of law from the right of the landowner to be placed in as good a position as money can accomplish, as of the date of taking. The value of the landholdings should equal the principal sum of just compensation due; interest compensates for the unpaid balance after taking.

The Court also cited Land Bank v. Santos (G.R. Nos. 213863 and 214021, January 27, 2016), emphasizing that "prompt payment" means payment in full as finally determined by the courts. A mere deposit of provisional compensation does not satisfy the legal requirement.

Interest Rate and Date of Taking

The Court clarified that the legal interest should be computed at 12% per annum on the unpaid balance from the time of taking—when the landowner was deprived of the use and benefit of the property—until June 30, 2013. Thereafter, the rate is 6% per annum until full payment, consistent with the amendment introduced by Bangko Sentral ng Pilipinas-Monetary Board Circular No. 799, series of 2013.

Since Land Bank claimed the title was transferred to the Republic but failed to attach copies, the Court remanded the case to the RTC to compute the correct interest, directing Land Bank to submit certified true copies of the Republic's title.

Practical Takeaways

• Final judgments are immutable. A final and executory decision can no longer be challenged or modified, even if errors are later discovered.
• Full payment is required. In agrarian reform cases, just compensation contemplates timely and full payment as finally determined by the courts.
• Interest is mandatory. The government cannot avoid interest by making partial or prompt provisional payments.
• Date of taking matters. Interest runs from the time the landowner is deprived of property, typically when title transfers to the Republic.
• Interest rates have changed. The applicable rate is 12% per annum until June 30, 2013, and 6% per annum thereafter.
