Understanding the Parol Evidence Rule in Philippine Contract Law

LIMKETKAI SONS MILLING, INC. VS. COURT OF APPEALS, BANK OF THE PHILIPPINE ISLANDS AND NATIONAL BOOK STORE, G.R. No. 118509, September 05, 1996

Imagine you’ve signed a lease agreement for a commercial space. The written contract clearly states the monthly rent, but later the landlord claims you verbally agreed to pay additional fees. Can they enforce this oral agreement? The answer often lies in the Parol Evidence Rule, a crucial principle in contract law.

This case, Limketkai Sons Milling, Inc. vs. Court of Appeals, delves into the intricacies of the Parol Evidence Rule, clarifying when oral testimony can and cannot override the terms of a written contract. The Supreme Court’s decision emphasizes the importance of written agreements and the limitations on introducing external evidence to alter their meaning.

The Legal Framework: Protecting Written Agreements

The Parol Evidence Rule, enshrined in the Rules of Court, Section 9, Rule 130, essentially states that when the terms of an agreement have been put into writing, that writing is considered the best evidence of the agreement. Oral or extrinsic evidence generally cannot be admitted to contradict, vary, add to, or subtract from the terms of the written agreement.

The rule aims to ensure stability and predictability in contractual relationships by preventing parties from later claiming that the written agreement doesn’t accurately reflect their intentions. It reinforces the idea that parties should carefully consider and reduce their agreements to writing to avoid future disputes.

Rule 130, Section 9 of the Rules of Court states: “When the terms of an agreement have been reduced to writing, it is considered as containing all the terms agreed upon and there can be, between the parties and their successors in interest, no evidence of such terms other than the contents of the written agreement itself…”

However, the Parol Evidence Rule is not absolute. There are exceptions, such as when a party alleges fraud, mistake, or ambiguity in the written agreement. In such cases, extrinsic evidence may be admissible to clarify the true intentions of the parties.

For example, if a contract contains a clause that is unclear or open to multiple interpretations, a court may allow evidence of prior negotiations or industry customs to determine the intended meaning of the clause.

The Case: Oral Agreement vs. Written Evidence

Limketkai Sons Milling, Inc. sought to enforce an alleged verbal contract for the sale of real property against the Bank of the Philippine Islands (BPI) and National Book Store. Limketkai claimed that despite the lack of a perfected written contract, a verbal agreement existed based on certain documents and actions.

The trial court initially admitted oral testimony to prove the existence of this verbal contract, even though BPI and National Book Store objected, arguing that the Statute of Frauds requires such agreements to be in writing.

The case journeyed through the courts:

• Trial Court: Ruled in favor of Limketkai, admitting oral testimony.
• Court of Appeals: Reversed the trial court’s decision, upholding the Parol Evidence Rule.
• Supreme Court: Initially reversed the Court of Appeals but, on reconsideration, affirmed the appellate court’s decision, emphasizing the absence of a perfected written contract.

The Supreme Court underscored the importance of timely objections to inadmissible evidence. While BPI and National Book Store did cross-examine witnesses, they also persistently objected to the admission of oral testimony regarding the alleged verbal contract. The Court held that these objections were sufficient to preserve their right to invoke the Parol Evidence Rule.

The Court stated, “Corollarily, as the petitioner’s exhibits failed to establish the perfection of the contract of sale, oral testimony cannot take their place without violating the parol evidence rule.”

The Court also emphasized the following:

“It was therefore irregular for the trial court to have admitted in evidence testimony to prove the existence of a contract of sale of a real property between the parties despite the persistent objection made by private respondents’ counsels as early as the first scheduled hearing.”

The Court further noted that the presentation of direct testimonies in “affidavit-form” made prompt objection to inadmissible evidence difficult, and the counsels’ choice to preface cross-examination with objections was a prudent course of action.

Practical Implications: Protect Your Agreements

This case serves as a reminder of the importance of reducing agreements, especially those involving real property, to writing. It also highlights the need for vigilance in objecting to the admission of inadmissible evidence during trial.

Businesses and individuals should ensure that all essential terms are clearly and unambiguously stated in the written contract. Any subsequent modifications or amendments should also be documented in writing and signed by all parties involved.

Key Lessons

• Get it in Writing: Always reduce important agreements to writing, especially those involving real estate or significant sums of money.
• Be Clear and Specific: Ensure that the terms of the written agreement are clear, complete, and unambiguous.
• Object Promptly: If inadmissible evidence is offered during trial, object immediately and persistently to preserve your rights.
• Document Modifications: Any changes or amendments to the original agreement should be documented in writing and signed by all parties.

Hypothetical Example: A business owner verbally agrees with a supplier on a specific delivery date. However, the written purchase order states a different delivery timeframe. Based on the Parol Evidence Rule, the written purchase order will likely prevail, unless the business owner can prove fraud or mistake in the written document.
