The Supreme Court has reiterated a vital principle of due process: arguments not initially presented in the trial court cannot be raised for the first time on appeal. This prevents unfair surprise and ensures that the appellate court only reviews matters already considered and decided upon by the lower court. This means parties must present their complete case from the outset, or risk losing the opportunity to raise new legal theories later in the appeal process, safeguarding fairness and orderly judicial proceedings.

The Shifting Sands of Legal Strategy: Can a Property Dispute Be Reinvented on Appeal?

In Elaine A. Del Rosario v. Melinda F. Bonga, a dispute arose from a Deed of Conditional Sale for a two-door apartment. Bonga, the respondent, sued Del Rosario, the petitioner, for rescission of the contract due to non-payment. Initially, Del Rosario’s defense centered on the marital dispute between the Bongas, arguing that both spouses needed to seek rescission and questioning to whom payment should be made. However, on appeal, Del Rosario introduced a new argument: that Bonga’s title to the property was flawed due to an earlier prohibited transfer from a National Housing Authority (NHA) awardee, which would make the conditional sale void. The Court of Appeals (CA) rejected this new argument, and the Supreme Court affirmed, emphasizing that new issues cannot be introduced at the appellate stage.

The Supreme Court anchored its decision on the fundamental principle that points of law, theories, issues, and arguments not brought to the attention of the lower court need not be, and ordinarily will not be, considered by a reviewing court. This is rooted in basic considerations of **due process**, which requires fairness and an opportunity for all parties to be heard at each stage of the proceedings. Allowing a party to raise new arguments on appeal would deprive the opposing party of the chance to respond and present evidence on those issues in the trial court, where factual findings are typically made. It disrupts the established judicial process, potentially leading to unjust outcomes based on incomplete information.

The Court acknowledged that exceptions exist to this rule, such as issues of jurisdiction or plain error. The issue of **lack of jurisdiction** over the subject matter can be raised at any stage of the proceedings, as it concerns the court’s fundamental power to hear the case. Furthermore, an appellate court may consider issues not properly raised during trial when there is **plain error**, meaning a clear and obvious mistake that affects substantial rights. Arguments may also be entertained when there are **jurisprudential developments** affecting the issues, or when the issues raised present a matter of public policy. However, the Court found that Del Rosario’s case did not fall under any of these exceptions.

Del Rosario argued that her case involved a matter of public policy, specifically socialized housing, due to the property’s origin as an NHA award. She invoked the provision in the Deed of Sale with Mortgage between the NHA and the original awardee, Morales, which prohibited alienation within five years without NHA’s consent. Del Rosario likened this prohibition to those found in the Public Land Act, which nullify certain conveyances within five years of the grant. She contended that the violation of this provision rendered Bonga’s claim to the property void, therefore the entire transaction was moot and she should not have to pay. The Supreme Court rejected this argument, noting a critical difference in the wording of the relevant provisions.

Specifically, the Public Land Act expressly states that prohibited transactions are **void**, effectively nullifying the grant. In contrast, the Deed of Sale with Mortgage provided merely for the **rescission** of the deed at the option of the NHA in case of unauthorized alienation. Since there was no evidence that the NHA had exercised this option to rescind the original sale, the Court concluded that the subsequent conveyance to Bonga’s husband was not automatically void.

Moreover, this distinction is not merely semantic. The provision in the Public Land Act reflects a strong public policy against land speculation and ensuring that land granted under homestead provisions remains with the intended beneficiaries. The clause in the Deed of Sale, while restricting alienation, primarily serves the NHA’s interest in maintaining control over its housing projects and ensuring compliance with its regulations. As such, the Court held that the facts of the case do not rise to a matter of public policy that would warrant deviation from the general rule against raising new issues on appeal.

This case underscores the importance of thorough preparation and strategic planning in legal proceedings. Litigants must carefully consider all possible legal theories and present them comprehensively at the trial level. Failure to do so may result in the waiver of those arguments on appeal, regardless of their potential merit. It serves as a reminder that effective legal advocacy requires not only a deep understanding of the law but also a keen awareness of procedural rules and their implications.
