3. KEY AMENDMENTS BY RULE

Below are the most significant changes introduced by A.M. No. 19-10-20-SC, organized by rule (focusing on notable revisions):

3.1. Rule 1 – General Provisions

Applicability and Construction: The language emphasizes that courts should interpret the rules “to secure a just, speedy, and inexpensive disposition” of every action or proceeding, highlighting the Supreme Court’s priority in avoiding technicalities that cause delay.
Hierarchy of courts: Reinforced that the Rules apply in all trial courts and, when appropriate, in other courts (e.g., quasi-judicial bodies) insofar as they are consistent with enabling statutes.

3.2. Rule 2 – Cause of Action

Splitting a single cause of action: Reiterated that splitting is disallowed. The amendments clarify that if splitting is discovered, it shall be a ground for dismissal.
Joinder of causes of action: Clarified procedures on joinder, ensuring no undue complexity arises.

3.3. Rule 3 – Parties to Civil Actions

Real party in interest: Reiterates the requirement that every action must be prosecuted and defended in the name of the real party in interest, with explicit mentions of substituted service where warranted.
Indigent parties: Clarifications on the representation and fee exemptions for indigent litigants; updated guidelines to ensure uniform court practice.

3.4. Rule 4 – Venue of Actions

Venue stipulations: The amendments underline that if there is a stipulation on venue, it is enforceable unless otherwise barred by law (e.g., in real actions involving real property, mandatory venue rules apply).
Improper venue: Courts shall now be more consistent in dismissing or transferring actions when venue is improperly laid.

3.5. Rule 5 – Uniform Procedure in Trial Courts

Consolidated certain procedures for MTCs and RTCs, ensuring a single standard procedure for civil cases unless otherwise specified by law.

3.6. Rule 6 – Kinds of Pleadings

Emphasis on complaint and answer: Distinctions clarified between permissive and mandatory counterclaims and cross-claims.
Third-party (impleader): The rule clarifies the procedure for filing third-party complaints, requiring leave of court in certain instances.

3.7. Rule 7 – Parts of a Pleading

Verification and Certification Against Forum Shopping:
- The verification must attest to the truthfulness of the allegations based on personal knowledge or authentic records.
- The certification against forum shopping must now be strictly complied with, and includes updates regarding authorized signatories (especially in corporate settings).

3.8. Rule 8 – Manner of Making Allegations

Specificity in allegations:
- Fraud or mistake must be specifically stated.
- Conditions precedent must be specifically averred if they are material.
Pleading judgments or official documents: Must be done specifically but concisely.

3.9. Rule 9 – Effect of Failure to Plead

Default:
- The rules on default have been tightened, emphasizing the court’s duty to see if the defendant truly failed to file a responsive pleading or if they have a meritorious defense.

3.10. Rule 10 – Amended and Supplemental Pleadings

Amendments as a matter of right: Allowed before a responsive pleading is served; beyond that, leave of court is required.
Material changes: The amendments remind parties that changes must not prejudice the adverse party’s defenses.

3.11. Rule 11 – When to File Responsive Pleadings

Shortened periods in certain instances:
- The defendant has 30 calendar days from service of summons (for ordinary civil actions) to file an Answer.
- For a complaint-in-intervention or third-party complaint, the period may differ but typically remains 30 calendar days from service.
Effect of special rules: If special laws provide a shorter or longer period, the special law controls.

3.12. Rule 12 – Bill of Particulars

Time to file: A motion for bill of particulars must be filed within the period to file a responsive pleading.
Purpose: To clarify vague or ambiguous pleadings; these clarifications can speed up litigation by preventing needless motions or misinterpretations.

3.13. Rule 13 – Filing and Service of Pleadings, Judgments, and Other Papers

One of the most substantial changes appears in Rule 13, reflecting technological updates:

Modes of Service:
- Personal service remains the preferred mode.
- Registered mail or courier service are valid next options.
- Electronic mail (email) or other electronic means: The amendments explicitly allow e-service (with court authorization or if parties consent/waive objection).
Proof of service:
- Detailed guidelines on how to prove service by electronic means or by courier.
Electronic filing:
- Courts can allow e-filing of pleadings; the official email address must be indicated in the pleading.

3.14. Rule 14 – Summons

Modes of service expanded and clarified:
1. Personal service: Still the default mode.
2. Substituted service: Allowed only after multiple attempts at personal service within a reasonable time.
3. Service by publication: Streamlined procedure, especially for defendants who are residents but temporarily out of the Philippines, or for those who are non-residents.
4. Service of summons by email or other electronic means: Authorized if the defendant’s whereabouts are unknown or personal/substituted service is not practicable, upon court approval, or if the defendant explicitly agrees.

3.15. Rule 15 – Motions

Litigated vs. ex parte motions: Clarifies which motions need to be set for hearing.
Non-litigated motions: Some motions (e.g., motion for extension of time to file pleading if unopposed) may be resolved ex parte.
Notice of hearing: Strict compliance is still required for litigated motions, but certain motions are now streamlined through written submissions and orders.

3.16. Rule 16 – Motion to Dismiss

The “omnibus motion rule” is reiterated, meaning grounds not raised in a motion to dismiss are generally deemed waived, except on specific jurisdictional issues or failure to state a cause of action.
Some grounds traditionally used in a motion to dismiss can now be raised as affirmative defenses (Rule 8, as cross-referenced).

3.17. Rule 17 – Dismissal of Actions

Dismissal upon notice by the plaintiff: The first dismissal is generally without prejudice, but a second dismissal may bar the plaintiff from filing the same claim.
Dismissal due to fault of the plaintiff: If the plaintiff fails to appear or comply with lawful orders, the case can be dismissed with prejudice unless otherwise ordered by the court.

3.18. Rule 18 – Pre-Trial

Mandatory pre-trial: The amendments underscore that pre-trial is mandatory, except in small claims or other summary procedures where pre-trial is not required in the same form.
Pre-trial briefs: Now must be served on the adverse party at least 3 calendar days before the pre-trial (or within a specified period). Non-submission or late submission can lead to adverse consequences (e.g., waiver of claims or defenses).
Court’s active role: The judge must personally conduct the pre-trial and encourage amicable settlement. The amendments emphasize enforcing the mandatory nature of alternative dispute resolution (ADR) avenues.

3.19. Rule 19 – Intervention

Clarifies the time and grounds for intervention.
Intervention must not unduly delay or prejudice the adjudication of the rights of the original parties.

3.20. Rule 20 – Calendar of Cases

Reiterates that trial courts must maintain an active calendar and set cases promptly to comply with continuous trial guidelines.

3.21. Rule 21 – Subpoena

Electronic issuance: Subpoenas may now be served electronically under certain conditions.
Penalties for disobedience remain consistent, reminding parties that spurious subpoenas or frivolous requests can be sanctioned.

3.22. Rule 22 – Computation of Time

Calendar days vs. working days: The rules clarify where “days” refer to calendar days instead of “working days,” unless otherwise stated.
Simplified approach to counting periods, eliminating confusion on half-days and Saturdays as non-business days.

3.23. Rules 23 to 29 – Depositions and Discovery

Discovery rules are largely retained but with some clarifications:
- E.g., the expedited timeline for filing and resolving motions for discovery.
- Encouragement of electronic depositions or remote depositions if feasible.
Sanctions for refusal to comply with discovery requests are reiterated, ensuring that parties cannot frivolously delay production of evidence.

3.24. Rule 30 – Trial

Continuous trial system alignment:
- Courts must conduct trials on consecutive and successive dates.
- Strict observance of setting hearing dates to avoid delay.
Agreed upon statements of facts: If the parties stipulate certain facts during pre-trial, the trial can be shortened.

3.25. Rule 31 – Consolidation or Severance

Consolidation is encouraged when it avoids multiple suits dealing with the same issues or parties.
Court discretion: The amendments reaffirm the court’s broad discretion to order consolidation or severance when it promotes the swift resolution of cases.

3.26. Rule 32 – Trial by Commissioner

Rules on referring certain issues to commissioners remain, but the court is urged to do so only when strictly necessary, to avoid added cost or delay.

3.27. Rule 33 – Demurrer to Evidence

No major textual change but clarifies that a demurrer is effectively a motion to dismiss based on insufficiency of evidence after the plaintiff rests. If granted, it is with prejudice unless reversed on appeal.

3.28. Rule 34 – Judgment on the Pleadings

Reiterates that if the answer fails to tender an issue or admits material allegations, the plaintiff may move for judgment on the pleadings, expediting resolution.

3.29. Rule 35 – Summary Judgments

Grounds remain similar (no genuine issue of material fact). The amendments clarify certain deadlines for opposing motions for summary judgment.

3.30. Rule 36 – Judgments, Final Orders, and Entry Thereof

Clarifies that judgments must be in written form and must succinctly state the court’s findings and conclusions.
The entry of judgment procedure remains but is now more aligned with electronic posting in some jurisdictions.

3.31. Rule 37 – New Trial or Reconsideration

Grounds remain:
1. Fraud, accident, mistake, or excusable negligence.
2. Newly discovered evidence.
3. Insufficiency of evidence or decision contrary to law.
The movant must file the motion within the reglementary period, highlighting once more that these deadlines are strictly enforced.

3.32. Rule 38 – Relief from Judgments or Orders

Relief petitions remain an extraordinary remedy, focusing on extrinsic fraud or other justifiable grounds.

3.33. Rule 39 – Execution, Satisfaction, and Effect of Judgments

Emphasizes the timeline for filing motions for execution and clarifies the manner of enforcing monetary judgments.
Electronic or remote methods for sale on execution may be considered by the court when feasible.

4. IMPACT ON LEGAL PRACTICE, LEGAL ETHICS, AND LEGAL FORMS

4.1. Legal Practice and Advocacy

Shortened and strict deadlines: Lawyers must be vigilant in computing periods, many of which use calendar days. Missing deadlines can easily result in waivers or defaults.
Heightened emphasis on ADR: Legal practitioners are expected to explore amicable settlements or mediation in pre-trial; failure to do so or to appear can lead to serious procedural consequences.
Active case management: Lawyers should be prepared with all evidence and witness details early, given the continuous trial system and stricter pre-trial procedures.

4.2. Legal Ethics

Certification against forum shopping and verification: The 2019 Amendments reinforce lawyers’ ethical duty to ensure the correctness of every pleading. Any misrepresentation can lead to disciplinary sanctions.
Duty of candor and cooperation with the court: The continuous trial system and pre-trial obligations require good faith in discovery, production of documents, and compliance with procedural orders.
Use of technology: Lawyers are ethically bound to use authorized technology responsibly—e.g., ensuring the correct email addresses, verifying e-service, and safeguarding confidentiality.

4.3. Legal Forms

Summons, notices, and orders: Must follow the updated templates, specifically to reflect:
- Possible electronic modes of service.
- Proper warnings on deadlines (now in calendar days).
- The requirement for accurate e-mail addresses if e-service is utilized.
Pleadings: Must incorporate the revised verification and certification requirements.
Pre-trial briefs: Must include comprehensive details (witness lists, documentary evidence, proposed stipulations) as mandated under Rule 18.

5. PRACTICAL TIPS & NOTABLE HIGHLIGHTS

Always confirm if your court has specific electronic service guidelines or pilot rules for e-filing—these can vary among jurisdictions but must follow the Supreme Court’s overarching framework.
Be mindful of the “mandatory provisions” (e.g., mandatory pre-trial, mandatory service requirements) to avoid outright dismissals or being declared in default.
Take advantage of streamlined motions practice: Some motions can be resolved without hearing. Properly identify which motions are litigated or ex parte to save time.
Expect stricter enforcement of time frames for answers, motions, and appeals—judges have less leeway to grant repeated extensions.
Incorporate ADR early: Under the revised pre-trial scheme, courts will actively push for mediation or settlement. This can help your client achieve a faster resolution.
Records management: The new rules encourage electronic means, so maintain an organized system of electronic files and docket tracking.
Training on e-service: Ensure staff and associates understand how to effect and prove e-service, including preserving relevant digital proofs (e.g., screenshots of sent emails, read receipts, courier tracking, etc.).
