GSIS vs. Pacific Airways Corporation

The pilot-in-command of a taxiing aircraft bears primary responsibility for ensuring that any air traffic control clearance is suitable before crossing an active runway, and gross negligence in disregarding the right of way of an aircraft on take-off roll constitutes the proximate cause of a collision, barring recovery of damages under Article 2179 of the Civil Code.

Pacific Airways Corporation operated a Twin Otter aircraft that arrived at the Manila International Airport from El Nido, Palawan, while Philippine Airlines operated a Boeing 737 preparing for departure from the same airport. The Air Transportation Office (ATO) exercised traffic management functions at the airport through ground and air traffic controllers governed by the Rules of the Air and the Rules of Air Control. The Government Service Insurance System (GSIS) insured PAL's Boeing 737 and intervened in the civil case as subrogee after indemnifying PAL for repair costs. A parallel criminal case for reckless imprudence resulting in damage to property with serious and slight physical injuries was separately tried in the RTC of Pasay City (Branch 108), resulting in the conviction of ATO controllers Alzola and Lim and the acquittal of Linog, Jr.

On 2 April 1996, at around 6:45 p.m., the Twin Otter aircraft of Pacific Airways Corporation arrived at the Manila International Airport from El Nido, Palawan, with Ely B. Bungabong as pilot-in-command and Michael F. Galvez as co-pilot. After the last passenger disembarked at the Soriano Hangar, PAC's pilots started the engine to proceed to the PAC Hangar at the other end of the airport. At around 7:18 p.m., Galvez contacted ground control to request clearance to taxi to taxiway delta. Rogelio Lim, the ground traffic controller on duty at the Air Transportation Office, issued the clearance on the condition that the pilots contact him again upon reaching the taxiway delta intersection. PAC's pilots then taxied to taxiway delta at about 7:19 and 19 seconds, and upon reaching the intersection, Galvez repeated the request to taxi, which was granted.

Upon reaching fox 1, Galvez requested clearance to make a right turn to fox 1 and to cross runway 13 in order to proceed to fox 1 bravo, and ATO granted the request. At this point, the Twin Otter was still 350 meters away from runway 13. Upon reaching runway 13, PAC's pilots did not make a full stop at the holding point to request clearance right before crossing the active runway. Without such clearance, they proceeded to cross runway 13.

Meanwhile, Philippine Airlines' Boeing 737, manned by pilots Rogelio Casiño and Ruel Isaac, was preparing for take-off along runway 13. The PAL pilots requested and received clearance to push and start from Ernesto Linog, Jr., the air traffic controller on duty. At 7:20 and 18 seconds, Linog, Jr. gave the Boeing 737 clearance to take off, and Casiño and Isaac proceeded with the take-off procedure. While already on take-off roll, Casiño caught a glimpse of the Twin Otter on the left side of the Boeing 737 about to cross runway 13. While the Twin Otter was halfway through runway 13, Galvez noticed the Boeing 737 and told Bungabong that an airplane was approaching from the right side. Bungabong exclaimed "Diyos ko po" and gave full power to the Twin Otter. The PAL pilots attempted to abort the take-off by reversing the thrust of the aircraft, but the Boeing 737 collided with the Twin Otter, dragging it about 100 meters away. The Twin Otter was a total wreck. Bungabong suffered a sprain on his shoulder while Galvez sustained a laceration on his left thumb; both were treated at Makati Medical Center.

On 7 May 1996, PAC, Bungabong, and Galvez filed a complaint for sum of money and damages against PAL, Casiño, Isaac, ATO, Lim, Linog, Jr., and ATO's traffic control supervisor Danilo Alzola in the RTC (Branch 112) of Pasay City. GSIS, as insurer of the Boeing 737, intervened. The trial court found the proximate cause of the collision to be the negligence of ATO controllers Alzola, Lim, and Linog, Jr., and the direct cause to be the negligence of PAL pilots Casiño and Isaac, ordering PAL, its pilots, ATO, and its controllers jointly and severally liable for actual, exemplary, and moral damages and attorney's fees. The Court of Appeals affirmed this ruling in toto, later modifying only to dismiss the case against Linog, Jr. based on his acquittal in a parallel criminal case. In that criminal case, the RTC (Branch 108) of Pasay City acquitted Linog, Jr. but convicted Alzola and Lim of reckless imprudence resulting in damage to property with serious and slight physical injuries; the convictions of Alzola and Lim became final as they did not appeal.

• Emergency Rule vs. Last Clear Chance (G.R. No. 170418, PAL, Casiño, Isaac): Petitioners argued that the Court of Appeals should have applied the emergency rule instead of the last clear chance doctrine, and that even if the PAL pilots were negligent, PAL had exercised due diligence in the selection and supervision of its pilots.
• Insufficiency of Damages Proof (G.R. No. 170418): Petitioners contended that the Court of Appeals awarded damages without any specific supporting proof as required by law.
• Entitlement to Counterclaim (G.R. No. 170418): Petitioners claimed that the Court of Appeals should have awarded their counterclaim for damages.
• PAC Pilots' Negligence as Proximate Cause (G.R. No. 170414, GSIS): Petitioner GSIS pointed out that PAC's pilots were the ones guilty of negligence as they violated the Rules of the Air, which provide that right of way belongs to the aircraft on take-off roll and the aircraft on the right side of another, and stressed that such negligence was the proximate cause of the collision.
• Solidary Liability of PAC (G.R. No. 170414): GSIS posited that PAC, Bungabong, and Galvez should be held solidarily liable to pay GSIS the cost of repairing the insured aircraft.
• Real Party-in-Interest (G.R. No. 170460, ATO, Alzola, Lim): Petitioners called attention to the fact that PAC was a mere lessee, not the owner, of the Twin Otter, and argued that as mere lessee, PAC was not the real party-in-interest in the complaint seeking recovery for damages sustained by the aircraft.
• Joint Responsibility for Clearances (G.R. No. 170460): Petitioners maintained that ground and air traffic clearances were the joint responsibility of ATO and the pilots-in-command, and averred that Bungabong and Galvez were negligent in asking for clearance to cross an active runway while still 350 meters away from the runway.
• Right of Way and Last Clear Chance (G.R. No. 170460): Petitioners claimed that PAL had the right of way and that PAC's pilots had the last clear chance to prevent the collision.

• Prematurity of Clearance Irrelevant (G.R. No. 170418): Respondents argued that it did not matter whether the clearance was premature or not as long as the clearance was actually granted, defending the position that PAC's pilots were entitled to rely on the clearance issued by ATO.

• Liability for Negligence: Whether, among PAC's pilots, PAL's pilots, and ATO's controllers, any or all are liable for negligence arising from the collision, and who bears the proximate causation of the incident.

• Liability for Negligence: Yes, as to PAC's pilots — they were grossly negligent and their negligence was the proximate cause of the collision. No, as to PAL's pilots — they had the right of way and were entitled to assume the taxiing aircraft would yield. ATO controllers Alzola and Lim were only contributorily negligent; Linog, Jr. was absolved based on his acquittal in the criminal case. PAC's complaint was dismissed, and PAC and its pilots were ordered to pay damages to PAL, its pilots, and GSIS.

• Liability for Negligence: Under the Rules of the Air, specifically Section 2.2.4.6, an aircraft taxiing on the maneuvering area of an aerodrome shall give way to aircraft taking off or about to take off. PAL's Boeing 737 was on take-off roll at the time of collision, while only the Twin Otter was taxiing; thus, PAL's aircraft had the right of way. PAC's pilots were grossly negligent for disregarding this right of way and for failing to make a full stop at the holding point to request updated clearance right before crossing the active runway. They had prematurely requested clearance while still 350 meters away from runway 13, and their defense that the prematurity of the clearance was irrelevant so long as it was granted only revealed poor judgment. The Rules of Air Control (Sections 1.3, 1.5, 3.1, and 10.1.5) place primary responsibility on the pilot-in-command for the operation of the aircraft and provide that clearances issued by controllers do not relieve pilots of responsibility for compliance with applicable rules. The clearance to cross runway 13 was not an absolute license to recklessly cross an active runway. The gross negligence of PAC's pilots — characterized by the want of even slight care and a conscious indifference to consequences — was the proximate cause of the collision, defined as that cause which in natural and continuous sequence, unbroken by any efficient intervening cause, produces the injury. Under Article 2179 of the Civil Code, when the plaintiff's own negligence is the immediate and proximate cause of his injury, he cannot recover damages. Accordingly, PAC and its pilots, whose own gross negligence was the immediate and proximate cause of their own injuries, must bear the cost and cannot recover damages. The negligence of ATO controllers Alzola and Lim in granting the premature request for clearance was only contributory and did not relieve PAC's pilots from complying with the Rules of the Air. Linog, Jr. was properly absolved because the trial court in the criminal case ruled he was not negligent, and the act from which civil liability might arise did not exist. PAL's pilots timely requested and received clearance to take off, and under Section 2.2.4.1 of the Rules of Air Control, the aircraft with the right of way shall maintain its heading and speed; it was reasonable for PAL's pilots to assume the taxiing aircraft would respect their right of way. By analogy with Santos vs. BLTB, a motorist properly proceeding on his own side is entitled to assume the other motorist will return to his proper lane. PAL's counterclaim for actual or compensatory damages was granted in the amount of US$548,819.93 for lease charges during the period the Boeing 737 was not flying. GSIS, as insurer subrogee under Article 2207 of the Civil Code, was entitled to reimbursement of US$2,775,366.84 for repair costs, fully supported by statements of account, check vouchers, and invoices. Moral damages of ₱100,000, exemplary damages of ₱100,000, and attorney's fees of ₱50,000 were awarded to Casiño and Isaac individually, given the gross negligence of PAC's pilots under Article 2231 of the Civil Code and the rule that attorney's fees are recoverable when exemplary damages are awarded under Article 2208.

• Proximate Cause — Proximate cause is that cause which, in natural and continuous sequence, unbroken by any efficient intervening cause, produces the injury, and without which the result would not have occurred. The Court applied this doctrine to hold that the gross negligence of PAC's pilots in disregarding PAL's right of way and failing to obtain updated clearance before crossing an active runway was the proximate cause of the collision.

• Gross Negligence — Gross negligence is characterized by the want of even slight care, acting or omitting to act in a situation where there is a duty to act, not inadvertently but willfully and intentionally with a conscious indifference to consequences insofar as other persons may be affected. The Court found PAC's pilots grossly negligent for crossing an active runway without proper clearance and without looking for oncoming traffic on a clear evening when the Boeing 737's lights were visible from 200 meters away.

• Plaintiff's Own Negligence as Bar to Recovery (Article 2179, Civil Code) — When the plaintiff's own negligence is the immediate and proximate cause of his injury, he cannot recover damages. If his negligence was only contributory, he may recover but the courts shall mitigate the damages. The Court applied this to bar PAC and its pilots from recovering damages, as their own gross negligence was the immediate and proximate cause of their injuries.

• Pilot-in-Command Responsibility (Rules of Air Control) — The pilot-in-command of an aircraft is responsible for the operation of the aircraft in accordance with the rules of the air and has final authority as to the disposition of the aircraft. Clearances issued by controllers relate to traffic and aerodrome conditions only and do not relieve a pilot of responsibility for compliance with applicable rules and regulations. The Court relied on this principle to reject PAC's pilots' defense that they were entitled to rely on the clearance issued by ATO.

• Right of Way in Aircraft Surface Movement (Rules of the Air, Section 2.2.4.6) — An aircraft taxiing on the maneuvering area of an aerodrome shall give way to aircraft taking off or about to take off. The Court applied this rule to establish that PAL's Boeing 737, being on take-off roll, had the right of way over PAC's taxiing Twin Otter.

• Insurance Subrogation (Article 2207, Civil Code) — If the plaintiff's property has been insured and he has received indemnity from the insurance company for the injury or loss, the insurance company shall be subrogated to the rights of the insured against the wrongdoer. If the amount paid does not fully cover the loss, the aggrieved party may recover the deficiency. The Court applied this to uphold GSIS's claim for reimbursement of repair costs as PAL's insurer subrogee.

• Last Clear Chance Doctrine (rejected in favor of right-of-way analysis) — The Court effectively rejected the application of the last clear chance doctrine urged by ATO petitioners, instead grounding liability on the right-of-way rules and the primary responsibility of the pilot-in-command.

• "The clearance to cross runway 13, premature as it was, was not an absolute license for PAC's pilots to recklessly maneuver the Twin Otter across an active runway." — This passage articulates the principle that air traffic control clearances do not absolve pilots of their primary responsibility to ensure safe operation, a central holding of the case.

• "Were it not for such gross negligence on the part of PAC's pilots, the collision would not have happened." — This statement crystallizes the Court's finding on proximate causation, tying the collision directly to the gross negligence of PAC's pilots.

• "Since the pilots-in-command have the final authority as to the disposition of the aircraft, they cannot, in case a collision occurs, pass the blame to ATO for issuing clearances that turn out to be unsuitable." — This passage defines the allocation of responsibility between air traffic controllers and pilots-in-command, a doctrine frequently relevant in aviation negligence cases.

• Santos vs. BLTB, 145 Phil. 422 (1970) — Applied by analogy. The Court invoked the principle that a motorist properly proceeding on his own side of the highway is entitled to assume that an approaching motorist on the wrong side will return to his proper lane, supporting the conclusion that PAL's pilots were entitled to assume PAC's taxiing aircraft would respect their right of way.

• Magaling vs. Ong, G.R. No. 173333, 13 August 2008, 562 SCRA 152 — Followed for the definition of gross negligence as the want of even slight care, acting or omitting to act willfully and intentionally with conscious indifference to consequences.

• Ramos vs. C.O.L. Realty Corporation, G.R. No. 184905, 28 August 2009, 597 SCRA 526 — Followed for the definition of proximate cause and the principle that a plaintiff whose own negligence is the immediate and proximate cause of his injury cannot recover damages.

• Pleno vs. Court of Appeals, 244 Phil. 213 (1988) — Cited for the rule that the award of moral and exemplary damages and attorney's fees is discretionary based on the facts and circumstances of each case.

• MEA Builders, Inc. vs. Court of Appeals, 490 Phil. 565 (2005) — Cited for the exception to the rule that only questions of law may be raised in a Rule 45 petition, specifically when the Court of Appeals' judgment is premised on a misapprehension of facts.

• Section 2.2.4.6, Rules of the Air (ATO) — Provides that an aircraft taxiing on the maneuvering area of an aerodrome shall give way to aircraft taking off or about to take off. Applied to establish that PAL's Boeing 737 on take-off roll had the right of way over PAC's taxiing Twin Otter.

• Section 2.2.4.7, Rules of the Air (ATO) — Governs surface movement of aircraft in case of danger of collision between two aircrafts taxiing, providing that when on converging courses, the aircraft with the other on its right shall give way. The Court noted this provision but held it inapplicable because only the Twin Otter was taxiing at the time of collision.

• Sections 1.3, 1.5, 3.1, and 10.1.5, Rules of Air Control (ATO) — Establish that the pilot-in-command is responsible for the operation of the aircraft, has final authority as to its disposition, and that clearances issued by controllers do not relieve pilots of responsibility for compliance with applicable rules. Applied to reject PAC's pilots' defense of reliance on ATO clearance.

• Article 2179, Civil Code — Provides that when the plaintiff's own negligence is the immediate and proximate cause of his injury, he cannot recover damages; if his negligence was only contributory, he may recover but damages shall be mitigated. Applied to bar PAC and its pilots from recovering damages.

• Article 2207, Civil Code — Provides for insurance subrogation, entitling the insurer to the rights of the insured against the wrongdoer. Applied to uphold GSIS's claim for reimbursement of repair costs as PAL's insurer subrogee.

• Article 2208, Civil Code — Provides that attorney's fees may be recovered when exemplary damages are awarded. Applied to justify the award of attorney's fees to Casiño and Isaac.

• Article 2231, Civil Code — Provides that in quasi-delicts, exemplary damages may be granted if the defendant acted with gross negligence. Applied to award exemplary damages against PAC's pilots.

Justices Diosdado M. Peralta, Roberto A. Abad, Jose Portugal Perez, and Jose C. Mendoza concurred.
