Spouses Mangaron vs. Hanna Via Design & Construction

The registered owner of a motor vehicle is directly and primarily responsible for the consequences of its operation to the public and third persons, regardless of who the actual owner might be. An order denying a demurrer to evidence may be challenged via certiorari under Rule 65 if the denial is issued with grave abuse of discretion, such as when the trial court disregards the registered owner rule despite its clear application.

Spouses Emilio and Erlinda Mangaron sustained serious physical injuries when a Ford Ranger pick-up they were in was bumped and dragged by an Isuzu truck with plate number PLM 612. The truck was driven by Crestino T. Bosquit. The Mangarons filed a civil complaint for damages before the Regional Trial Court of Malolos City, Bulacan, naming as defendants Hanna Via Design & Construction – Deepwell Drilling Division, Power Supply and Equipment Parts, and the driver Bosquit. The complaint grounded liability on Article 2184 of the Civil Code, in relation to Article 2180, asserting that respondent Hanna Via was the employer of Bosquit and thus vicariously liable for the driver’s negligence.

• The collision: Spouses Emilio and Erlinda Mangaron were riding in a Ford Ranger pick-up with plate number XJZ-830 when it was struck and dragged by an Isuzu truck bearing plate number PLM 612. The truck was driven by Crestino T. Bosquit. The Mangarons suffered serious physical injuries and were hospitalized for a month at Davao Doctors Hospital. The accident occurred in Davao City.
• The complaint: Petitioners filed a civil action for damages against respondent Hanna Via Design & Construction – Deepwell Drilling Division, Power Supply and Equipment Parts, and the driver Bosquit. The complaint invoked Article 2184, in relation to Article 2180, of the Civil Code, alleging that Hanna Via was Bosquit’s employer and thus vicariously liable for his negligent driving.
• The motion for demurrer and the registered owner issue: After petitioners presented their evidence, Hanna Via moved for a demurrer to evidence. It raised two main grounds: (a) the RTC lacked jurisdiction because the complaint was essentially criminal in nature and should have been filed in Davao City where the incident occurred; and (b) the evidence showed that the registered owner of the Isuzu truck was not Hanna Via but Power Supply and Equipment Parts, a co-defendant.
• RTC’s orders: The trial court denied the demurrer, ruling that jurisdiction was proper because the complaint was civil in form, and that the question of ownership and Hanna Via’s relationship to Bosquit were evidentiary matters better resolved at trial. The motion for reconsideration was similarly denied.
• Undisputed fact on appeal: It was undisputed before the appellate court and the Supreme Court that the certificate of registration for the Isuzu truck bore the name Power Supply and Equipment Parts, not Hanna Via.

• Impropriety of certiorari: Petitioners argued that the Court of Appeals erred in giving due course to the Petition for Certiorari because the denial of a demurrer to evidence is an interlocutory order, and certiorari under Rule 65 is not the proper remedy to challenge such an order absent a clear showing of grave abuse of discretion.
• Sufficient basis for denial: Petitioners maintained that the trial court’s denial of the demurrer was correct because there was sufficient evidence on record to establish respondent’s liability, particularly Hanna Via’s own admission of ownership over the subject vehicle. They urged a pragmatic interpretation that would hold Hanna Via liable based on its alleged admission.

• Jurisdiction: Respondent Hanna Via contended that the complaint was actually a criminal action for reckless imprudence resulting in physical injuries and should have been filed in Davao City where the accident happened. (The CA rejected this argument, and it was not pursued further before the Supreme Court.)
• Inapplicability of vicarious liability under the registered owner rule: Respondent argued that the demurrer should have been granted because the undisputed registered owner of the Isuzu truck was Power Supply and Equipment Parts, not Hanna Via. As the party with no registration-based link to the vehicle, Hanna Via could not be held directly and primarily liable to third persons under the motor vehicle registration law.

• Remedy — Certiorari against denial of demurrer: Whether the Court of Appeals correctly entertained the Petition for Certiorari from an interlocutory order denying a demurrer to evidence.
• Grave abuse of discretion — Registered owner rule: Whether the trial court committed grave abuse of discretion in denying the demurrer despite the clear application of the registered owner rule.

• Remedy — Certiorari against denial of demurrer: An order denying a demurrer to evidence is interlocutory and thus unappealable under Section 1, Rule 41 of the Rules of Court. The general rule is that certiorari under Rule 65 is not available to challenge interlocutory orders. By way of exception, a certiorari petition may lie if the denial is tainted with grave abuse of discretion amounting to lack or excess of jurisdiction. The appellate court therefore properly assumed jurisdiction to determine whether the exception applied.
• Grave abuse of discretion — Registered owner rule: The denial of the demurrer was tainted with grave abuse of discretion. Under the registered owner rule, the person whose name appears on the certificate of registration of a motor vehicle is directly and primarily responsible for the consequences of its operation to the public and third persons, regardless of who the actual owner might be. Since it was undisputed that Power Supply, not Hanna Via, was the registered owner of the Isuzu truck, the evidence presented by petitioners against Hanna Via was insufficient as a matter of law to sustain a claim for vicarious liability. The trial court’s failure to apply this settled rule and its insistence on treating the matter as a mere evidentiary issue constituted grave abuse of discretion. The proper recourse for petitioners would be to proceed against the registered owner, Power Supply, who in turn may seek indemnity from the actual owner through a cross-claim.

• Registered owner rule — The registered owner of a motor vehicle is directly and primarily liable to the public and third persons for damages or injuries caused by its operation on public highways. The rule is founded on the public policy underlying compulsory motor vehicle registration, which aims to fix responsibility on a definite, readily identifiable individual so that victims need not engage in the difficult task of ascertaining the true owner or driver. Even if the vehicle has been sold or transferred, the registered owner remains the lawful operator insofar as third persons are concerned; the actual operator is regarded merely as the registered owner’s agent. The registered owner who satisfies a judgment may seek reimbursement from the real owner under the principle against unjust enrichment.

• Demurrer to evidence — Defined as an objection by a party that the adversary’s evidence is insufficient, as a matter of law, to make out a case or sustain the issue. A denial of a demurrer is an interlocutory order, not appealable, but may be challenged via certiorari if issued with grave abuse of discretion.

• Certiorari against interlocutory order — As an exception to the general rule, certiorari under Rule 65 lies to challenge an interlocutory order denying a demurrer to evidence when the denial is shown to be tainted with grave abuse of discretion amounting to lack or excess of jurisdiction.

• "Registration is required not to make said registration the operative act by which ownership in vehicles is transferred, as in land registration cases, because the administrative proceeding of registration does not bear any essential relation to the contract of sale between the parties, but to permit the use and operation of the vehicle upon any public highway (section 5 [a], Act No. 3992, as amended.) The main aim of motor vehicle registration is to identify the owner so that if any accident happens, or that any damage or injury is caused by the vehicle on the public highways, responsibility therefore can be fixed on a definite individual, the registered owner." — This passage encapsulates the policy rationale for the registered owner rule, emphasizing victim protection and ease of identification.

• "Regardless of sales made of a motor vehicle, the registered owner is the lawful operator insofar as the public and third persons are concerned; consequently, it is directly and primarily responsible for the consequences of its operation. In contemplation of law, the owner/operator of record is the employer of the driver, the actual operator and employer being considered as merely its agent." — Quoting Equitable Leasing Corporation v. Suyom, the Court restated the strict identification of the registered owner as the employer for purposes of tort liability.

• "However, the application of the registered owner rule does not serve as a shield of the offending vehicle’s real owner from any liability. The law is not inequitable. Under the principle of unjust enrichment, the registered owner who shouldered such liability has a right to be indemnified by means of a cross-claim as against the actual employer of the negligent driver." — This clarifies that the rule does not leave the registered owner without recourse, preserving internal equity while upholding public policy.

• Equitable Leasing Corporation v. Suyom, 437 Phil. 244 (2002) — Followed: The registered owner rule was applied; the Court reiterated that the registered owner is the lawful operator to the public and is considered the employer of the driver for purposes of Article 2176 in relation with Article 2180 of the Civil Code.
• FEB Leasing and Finance Corporation v. Spouses Baylon, 668 Phil. 184 (2011) — Cited for the consistent application of the registered owner rule.
• Metro Manila Transit Corporation v. Cuevas, 759 Phil. 286 (2015) — Cited for the rationale that motor vehicle registration fixes liability on a definite individual to protect the public.
• Filcar Transport Services v. Espinas, 688 Phil. 430 (2012) — Cited for the indemnity cross-claim available to the registered owner against the actual employer.
• Choa v. Choa, 441 Phil. 175 (2002) — Cited for the definition of demurrer to evidence and the rule that certiorari may lie against an order denying a demurrer when grave abuse of discretion is shown.

• Articles 2176, 2180, and 2184, Civil Code — These provisions on quasi-delicts and vicarious liability formed the basis of the petitioners’ complaint. Article 2180, in particular, makes employers liable for damages caused by their employees acting within the scope of their assigned tasks. The registered owner rule operates to identify the legal employer for purposes of this article where motor vehicles are concerned.
• Section 1, Rule 41, Rules of Court — No appeal may be taken from an interlocutory order. This provision barred a direct appeal from the denial of a demurrer, making certiorari under Rule 65 the available remedy upon a showing of grave abuse of discretion.
• Rule 65, Rules of Court — Invoked as the procedural vehicle for questioning the interlocutory order through a special civil action for certiorari.
