When an earthquake caused the collapse of the Ruby Tower in Manila in 1968, the tragedy raised a profound legal question: could the contractors, architects, and engineers be held liable for damages, or was the destruction purely an act of God? This question was resolved in Nakpil & Sons v. Court of Appeals (G.R. No. L-47851, October 3, 1986), a case that remains a cornerstone of Philippine jurisprudence on real estate liability.

The petitioners argued that the earthquake was a fortuitous event, beyond human control, and that under Article 1174 of the Civil Code, they should be exempt from liability. The Court, however, examined the evidence and concluded that negligence in design and construction had contributed to the building’s collapse. The ruling made it clear: a fortuitous event does not excuse liability when human negligence concurs in producing the damage.

The Court declared, “The principle of fortuitous event cannot apply where the negligence of the obligor concurs with the fortuitous event in producing the damage. Negligence is not excused by fortuitous event.” In other words, while the earthquake was indeed an act of nature, the faulty workmanship and design defects were man-made, and together they caused the catastrophic failure.

This case remains directly relevant to real estate practice because it clarifies how responsibility is allocated when property is damaged by natural disasters. For builders and developers, Nakpil is a stern warning. It shows that compliance with the Building Code, zoning ordinances, and engineering standards is not optional but a legal duty. An earthquake may be unavoidable, but if poor materials, inadequate structural design, or shortcuts in construction contribute to the collapse, liability attaches. Developers cannot simply invoke force majeure; their reputation, financial exposure, and even criminal liability may be at stake.

For appraisers, the ruling highlights a subtle but crucial point. When valuing damaged property, it is necessary to ask: Was the loss caused solely by the disaster, or was it aggravated by negligence? If the latter, the cost to cure or diminution in value may be subject to claims against contractors, engineers, or insurers. This affects appraisal reports for insurance claims, litigation support, and even expropriation where consequential damages are assessed.

For insurers, Nakpil clarifies the boundaries of coverage. Many property policies exclude “acts of God” like earthquakes, but this case shows that where negligence coexists with a natural event, liability persists. Thus, insurers must carefully examine claims to determine if negligence by contractors or owners triggered coverage. It also guides insurers in drafting clearer clauses about fortuitous events, exclusions, and subrogation rights.

For property owners, the case is a lesson in vigilance and due diligence. Choosing competent contractors, hiring licensed engineers and architects, and ensuring that designs comply with earthquake-resistant standards are not just business decisions but safeguards against loss. Owners cannot assume that “insurance will pay” or that “the disaster was unavoidable.” The law demands that owners protect their property with foresight.

For the broader real estate industry, Nakpil underscores the link between law, valuation, and social responsibility. The safety and integrity of buildings directly affect communities, not just investors. When negligence meets disaster, lives and livelihoods are lost. By holding professionals accountable, the Supreme Court reinforced a culture of responsibility — one that appraisers, brokers, assessors, and developers must uphold in a disaster-prone country like the Philippines.

The continuing lesson of Nakpil is accountability- natural events may be unavoidable, but their impact is often determined by human foresight, planning, and diligence. In a country as disaster-prone as the Philippines, this doctrine safeguards the public by ensuring that responsibility cannot be avoided under the blanket excuse of force majeure.

Doctrine: Nakpil ensures that earthquakes and other disasters do not excuse negligence. Builders must build right, appraisers must distinguish causes of damage, insurers must test the limits of coverage, and property owners must demand quality. In real estate, accountability and preparedness remain the first defenses against natural calamities.
