Facts
1. In 1970, Danilo D. Reyes purchased a parcel of land from Regina Castillo. The land was titled under Original Transfer Certificate of Title (OCT) No. P-2388, issued pursuant to Free Patent No. V-79606.
2. Upon acquiring it, Reyes introduced improvements: planted numerous fruit-bearing trees (approx. a thousand mango trees, more than a hundred mandarin-citrus trees, more than a hundred guyabano trees).
3. TCT No. 45232 was later issued in his name.
4. The Republic (through the Bureau of Forest Development / DENR) filed a Complaint for Cancellation of Title and/or Reversion, claiming that about 162,500 square meters of the land were part of timberland (inalienable public forest land) under applicable land classification maps. Thus that portion could not be alienated or titled.
5. Both the Regional Trial Court (RTC) and Court of Appeals (CA) held that the title of Reyes over that portion was null and void, ordered cancellation of the title, surrender of title documents, vacating the premises, and reversion of property to the government.
6. After finality of those decisions, Reyes filed a motion to remove improvements (Rule 39, Section 10(d), 1997 Rules of Civil Procedure), asking for a period (one year) to remove/cut/appropriate the fruit trees he had planted. The RTC granted the motion. The CA affirmed.
7. The Republic opposed, arguing, among others, that this post-final judgment motion was barred by res judicata / prior judgment, and that removal of improvements should not be allowed, esp. since the land is public domain (timberland).
Issues
1. Jurisdiction / Finality: Whether the motion to remove improvements filed by Reyes, after the reversion / cancellation case had become final, could still be granted — that is, whether the courts may vary or grant incidental relief even after final judgment.
2. Good Faith and Rights over Improvements: Whether Reyes, as planter/sower in good faith, is entitled to remove improvements, or at least to demand just compensation, under provisions of the Civil Code (esp. Articles on accession, useful and necessary improvements). And whether failing to grant him remedy amounts to unjust enrichment on the part of the State.
3. Feasibility / Environmental / Public Policy Constraints: Even if law permits removal, is removal of these improvements feasible without damage, and whether public interest under the Agro-Forestry Farm Lease Agreement (AFFLA) / environmental law require a different remedy.
Holding / Ruling
The Supreme Court denied the petition of the Republic, thereby affirming the CA decision, but with modifications.
The modification ordered: The RTC is to determine the actual improvements introduced by Reyes, their current value, and the expenses he incurred, for the period from 1970 until May 13, 1987. The Republic (through the BFD / DENR) is to pay Reyes that value, with a right of subrogation against the lessee under the AFFLA (Atty. Marte).
The Court held that Reyes was a planter in good faith, and that the State would be unjustly enriched if it simply took all the fruit-bearing trees / improvements without compensating him.
The Court also held that removal of the improvements (i.e. Reyes physically digging up or cutting/uprooting the trees) would risk substantial damage to the public land, would conflict with the conservational duties under AFFLA, and thus that the better remedy is compensation rather than physical removal.
Ratio Decidendi
From the decision, these legal principles / rationales underlie the ruling:
1. Inalienable Public Land / Timberland Cannot Be Subject to Disposition: Lands classified as public forest / timberland are non-alienable, non-disposable. Even if someone holds a title purporting to cover them, such title is null for that portion which belongs to public domain. (E.g. categories under law, land classification maps, requirement of certification from the Bureau of Forestry / Forest Management Bureau etc.)
2. Doctrine of Good Faith and Rights to Improvements: A person who in good faith believes he owns land, thereafter builds / plants, is entitled under the Civil Code (particularly Articles 445, 448, 546) to remedy with respect to improvements: either removal or, where removal is impossible or inadvisable, compensation (value of improvements). The doctrine of accession (and related Civil Code provisions) offers protections even when later it turns out title is invalid.
3. Unjust Enrichment (Article 22, Civil Code): The State (or in this case, Republic) must not be permitted to benefit from improvements at the expense of another without legal or equitable compensation. If the State will acquire the benefits (e.g., fruit trees), and the other party will suffer a loss, then equitable principles require restitution / indemnification. Nemo cum alterius detrimento locupletari potest (no one should profit at another’s expense).
4. Rule 39, Section 10(d), 1997 Rules of Civil Procedure: Provides procedural vehicle for removal of improvements in property subject of execution, but the procedural possibility does not always lead to physical removal—courts must consider feasibility, fairness, public interest. Since removal would damage the land (under the AFFLA obligations, environment etc.), physical removal is not the equitable solution in this case.
5. Finality of Judgment Does Not Bar Relief for Remedies Overlooked: Even though the reversion / cancellation decision was final, the courts may still grant relief in the nature of incidental motions for improvements, especially when prior judgments did not address improvements or compensation. The refusal to consider improvements would sacrifice substantive justice merely for technical finality.
Legal Significance / Implications
The decision confirms that good faith in property acquisition matters significantly even when the title is later voided: improvements done in good faith are not lost automatically; the owner may recover for improvements or retain until payment.
It underscores the State's duty not to be unjustly enriched when taking over improvements introduced by private persons who thought they had valid title.
It places limits on res judicata / finality doctrine—not absolute when relief sought is incidental and pertains to remedies not previously addressed.
It also shows that environmental or public interest (e.g. under Agro-Forestry Lease, conservation, watershed protection) may limit or modify what improvements may be removed; compensation may be more appropriate.
