Below is a comprehensive discussion of affirmative defenses under Philippine civil procedure, focusing on (1) Section 5(b), Rule 6 of the Rules of Court (defining and enumerating affirmative defenses) and (2) Section 12, Rule 8 of the 2019 Revised Rules of Civil Procedure (governing the pleading and resolution of affirmative defenses). This discussion also contextualizes how affirmative defenses differ from negative defenses, how and when they must be pleaded, and the procedural effects of invoking them.
1. CONCEPT OF DEFENSES UNDER THE RULES
A. Negative Defenses (Section 5[a], Rule 6)
- Definition: Negative defenses specifically deny the material or essential allegations in the plaintiff’s pleading (e.g., the complaint). By denying the facts the plaintiff relies upon, the defendant compels the plaintiff to prove those facts during trial.
- Examples: A simple denial of the alleged fact of indebtedness, or denying that an event giving rise to liability ever occurred.
B. Affirmative Defenses (Section 5[b], Rule 6)
- Definition: Affirmative defenses are allegations of new matters which, while hypothetically admitting the material allegations of the complaint, would nonetheless prevent or bar recovery by the plaintiff. In other words, they supply independent reasons why the plaintiff should not prevail, even if the plaintiff’s factual allegations were true.
- Examples:
- Fraud
- Release (e.g., a waiver or quitclaim)
- Payment
- Illegality of the contract or transaction
- Prescription or statute of limitations
- Statute of frauds
- Estoppel
- Res judicata
- Extinguishment of the obligation (e.g., compensation, remission, novation, etc.)
- Any other matter by way of confession and avoidance
Because these defenses raise new matter, they must be specifically and clearly pleaded in the defendant’s Answer (and supported by factual details, not mere conclusions).
2. AFFIRMATIVE DEFENSES IN RELATION TO RULE 8
A. Rule 8, Section 12 (Affirmative Defenses)
Under the 2019 Revised Rules of Civil Procedure, Section 12, Rule 8 places particular emphasis on affirmative defenses by:
- Requiring that affirmative defenses be raised in the Answer.
- Mandating that the court motu proprio resolve certain affirmative defenses within a fixed period (generally 30 days from the filing of the Answer).
The rule recognizes the following matters as grounds for outright dismissal when raised as affirmative defenses:
- Lack of jurisdiction over the person of the defending party;
- Lack of jurisdiction over the subject matter;
- Improper venue;
- Plaintiff’s lack of legal capacity to sue;
- Litigation was barred by res judicata, statute of limitations, or by a prior judgment or pending action between the same parties for the same cause;
- Forum-shopping; and
- Other grounds enumerated under the Rules which, if pleaded as an affirmative defense, would warrant the dismissal of the complaint.
B. Waiver and Mandatory Resolution
Waiver of Affirmative Defenses
- As a general rule, any affirmative defense not raised in the Answer is deemed waived.
- Some exceptions are recognized by jurisprudence for defenses that go into the fundamental competence of the court (e.g., lack of jurisdiction over the subject matter can be raised at any time).
Court's Duty to Resolve
- Under the 2019 Rules, the court is required to resolve the aforementioned affirmative defenses within 30 calendar days from the filing of the Answer.
- If the court grants the affirmative defense, it can lead to dismissal of the complaint (in whole or in part).
- If the court denies or does not sustain the affirmative defense, the case proceeds to the next stage (e.g., pre-trial).
Effect of Partial Affirmative Defense
- When an affirmative defense is successful in part (e.g., partial payment), it can lead to the reduction of the amount claimed or dismissal of only some causes of action or some defendants.
3. WHY PLEAD AFFIRMATIVE DEFENSES PROPERLY
Preclusion/Estoppel
- If an affirmative defense is not pleaded, a defendant may be barred from introducing evidence on that defense at trial.
- The reason is that affirmative defenses must be set out in such a way that the plaintiff is on notice of the defense and has the opportunity to address it.
Early Dismissal or Savings on Time and Resources
- Proper invocation of an affirmative defense (e.g., prescription, res judicata) may allow the court to dismiss the case early, eliminating the need for lengthy litigation.
- This promotes speedy and efficient disposal of cases, in line with the policy behind the 2019 amendments to the Rules of Civil Procedure.
Obligation of Candor and Specificity
- A mere legal conclusion (e.g., “the claim is barred by the statute of limitations”) is insufficient.
- Rule 8 (on the manner of making allegations) requires that claims or defenses based on fraud, mistake, or other special matters be stated with particularity.
4. DISTINCTION BETWEEN AFFIRMATIVE AND NEGATIVE DEFENSES
- Negative Defense denies basic facts alleged in the complaint (e.g., “I did not borrow money,” or “There was no contract”).
- Affirmative Defense effectively admits that the plaintiff’s factual allegations might be true but argues there is a separate or superseding reason the plaintiff cannot recover (e.g., “Yes, there was a loan, but it has been fully paid,” or “Yes, there was a contract, but the claim has prescribed.”).
Understanding this distinction is critical when drafting answers: negative defenses test the sufficiency or veracity of plaintiff’s allegations, while affirmative defenses add new matter to defeat the claim.
5. RELEVANT PROCEDURAL POINTS
Form and Content Requirements
- Under the Rules, pleadings must contain a concise statement of the ultimate facts on which the party relies.
- Affirmative defenses must similarly be stated with clarity, enumerating factual grounds (and attaching supporting documents when applicable).
Timing
- Affirmative defenses are raised in the Answer, which is typically filed within 30 calendar days (for ordinary civil actions) from receipt of summons (subject to exceptions or other rules in special proceedings).
- Failure to do so generally waives them, except for those defenses that the courts and jurisprudence allow to be raised even later (such as lack of subject-matter jurisdiction).
Motion to Dismiss vs. Affirmative Defenses
- Under the 2019 Revised Rules, the grounds for a motion to dismiss in ordinary civil actions have been restricted. Many of the former grounds for a motion to dismiss must now be pleaded as affirmative defenses in the Answer (Rule 8, Section 12).
- The court can still dismiss the complaint based on those affirmative defenses if it finds them meritorious after the plaintiff has had the chance to respond.
Resolution of the Affirmative Defenses
- After the defendant files the Answer with affirmative defenses, the plaintiff may file a reply to specifically deny or controvert the new matters.
- The court then determines whether any of the pleaded affirmative defenses warrant dismissal or some other action (e.g., dropping a party, striking a claim, limiting issues).
- The judge’s ruling on the affirmative defenses is typically embodied in an order prior to pre-trial.
6. SPECIAL NOTES ON SELECT AFFIRMATIVE DEFENSES
Lack of Jurisdiction over the Subject Matter
- Cannot be waived and may be raised at any time, even on appeal.
- If granted, leads to the outright dismissal of the case.
Prescription (Statute of Limitations)
- Must be specifically pleaded; the defendant must indicate (1) when the cause of action accrued and (2) how long the applicable prescriptive period is.
- Failure to plead it generally waives the defense.
- If granted, the complaint is dismissed with prejudice.
Res Judicata
- Applies when there is a prior final judgment involving the same parties, same cause of action, and same subject matter.
- Must be specifically invoked; if granted, results in dismissal with prejudice.
Forum Shopping
- If the defendant can show that the plaintiff engaged in forum shopping, the complaint may be dismissed.
- Usually presented with documentation showing another pending case or prior dismissed/decided case with the same parties and same causes.
Payment and Other Modes of Extinguishment
- Requires specific detail: date of payment, amount, or the nature of the extinguishing act.
- Supporting documentary evidence (e.g., receipts, acknowledgment) is strongly advisable.
Statute of Frauds
- Typically raised in contracts that must be in writing under Art. 1403(2) of the Civil Code (e.g., agreements not to be performed within one year, sale of real property, etc.).
- As an affirmative defense, the defendant must state how or why the contract sued upon falls within the Statute of Frauds and lacks the required form.
7. PRACTICAL STRATEGIES IN RAISING AFFIRMATIVE DEFENSES
Drafting the Answer
- Clearly separate negative defenses and affirmative defenses for ease of reference and to ensure compliance with Rule 8.
- Provide a section labeled “Affirmative Defenses,” enumerate them, and provide sufficient factual detail for each.
Attach Evidence
- Where possible, attach documentary evidence (e.g., receipts, deeds, prior judgments) or at least reference them if they are too voluminous, so the court can see immediately the basis for the affirmative defense.
- This helps the court resolve the defense promptly under Rule 8, Section 12.
Anticipate Court’s Timeline
- Keep in mind the court has 30 calendar days from the filing of the Answer to rule on the affirmative defenses.
- Prepare for the possibility of an early dismissal or an early denial of your affirmative defense, which will shape your strategy moving into pre-trial or appeal.
Be Meticulous and Accurate
- An imprecise or incomplete factual assertion in an affirmative defense might render it ineffective.
- For instance, merely stating “The claim has prescribed” without specifying when the alleged cause of action accrued and what the prescriptive period is might lead the court to deny that defense outright.
8. IMPLICATIONS OF COURT’S RULING ON AFFIRMATIVE DEFENSES
Sustained Defense → Dismissal/Partial Dismissal
- If the court sustains an affirmative defense that goes to the entire claim (e.g., lack of subject matter jurisdiction or prescription of the entire cause of action), the complaint is dismissed outright (often “with prejudice” unless the defect is jurisdictional, in which case it is simply dismissed).
- If the defense affects only part of the claim, the court may dismiss only that portion or cause of action.
Overruled Defense → Proceed to Pre-trial and Trial
- The denial of an affirmative defense means the court finds it insufficient at the preliminary stage.
- The defendant can still pursue the defense during trial if it is a factual matter, unless the court’s order specifically disallows it.
Possibility of Interlocutory Relief
- An order denying an affirmative defense (other than one involving jurisdiction) is typically interlocutory, meaning it cannot be appealed immediately; the defendant must wait until final judgment to appeal.
- If lack of jurisdiction is at issue, certiorari or other special remedies might be considered.
9. KEY TAKEAWAYS
- Affirmative defenses must be clearly and specifically pleaded in the Answer; most are waived if not pleaded.
- The 2019 Revised Rules place importance on the speedy resolution of affirmative defenses (Section 12, Rule 8 mandates their prompt resolution).
- Properly raised affirmative defenses can streamline litigation, reduce costs, or even result in an early dismissal of the complaint.
- Jurisdictional defenses (especially lack of subject matter jurisdiction) stand as an exception: they cannot be waived and may be raised at any stage.
- The defendant must provide sufficient factual detail and, where feasible, documentary support in invoking an affirmative defense.
Final Note
While the foregoing is a thorough guide to affirmative defenses under Sections 5(b), Rule 6 and 12, Rule 8 of the 2019 Revised Rules of Civil Procedure, always remember that effective pleading depends on the specific facts of each case. The enumerations in the Rules are not exhaustive—any matter that confesses and avoids liability can be an affirmative defense, provided it is properly pleaded.
Due diligence, attention to procedural deadlines, and precise drafting cannot be overstated. A well-prepared Answer with properly articulated affirmative defenses can decisively shape the course of a lawsuit under Philippine procedural law.
