G.R. No. L-18390 - Velasco vs. Manila Electric Co.

Case Summary (G.R. No. L-18390)

Factual Background

In 1948, Pedro J. Velasco purchased three adjoining lots at the corner of South D and South 6 Streets, Diliman, Quezon City, in an area zoned as a “first residence” district. He sold two of the lots to Manila Electric Co. but retained the lot on which he built his residence, the lot being about ten to twenty meters from where Manila Electric Co. later erected a substation. In September 1953 the company constructed the substation, completing it in November 1953, without first obtaining a building permit or authority from the Public Service Commission. The substation contained transformers rated up to 10,000 Kva without fan cooling and up to 12,500 Kva with fan cooling and served not less than 8,500 residential customers, over 300 commercial establishments, and about 30 industries. The company erected a stone and cement wall along the streets but maintained only an interlink wire fence along the side adjoining Velasco’s property. A continuous humming or droning sound emanated from the transformers and was audible in and about the plaintiff’s house.

Trial Court Proceedings

Pedro J. Velasco sued for abatement of the alleged nuisance and for damages, claiming that the continuous noise injured his health and business and seeking P487,600.00 in damages. The Court of First Instance dismissed the complaint, finding that the substation noise was unavoidable, did not constitute a legal nuisance, could not have caused the illnesses alleged, and that claimed damages were inadequately proven. The plaintiff appealed.

Legal Issue

The central legal question before the Court was whether the continuous noise emitted by Manila Electric Co.’s substation constituted an actionable nuisance under Article 694 of the Civil Code and whether the company was liable for damages under Article 2202. Ancillary issues included the extent of damages, the duty to mitigate under Article 2203, and whether Anastacio A. Agan, City Engineer, was solidarily liable.

Parties’ Contentions

Pedro J. Velasco contended that the perpetual sound from the substation since 1954 had disturbed his concentration and sleep, impaired his health and professional earnings, and depreciated his property, thus creating an actionable nuisance entitling him to abatement and compensatory, moral and other damages. Manila Electric Co. maintained that the humming was inherent in transformer operation, that the noise level inside the plaintiff’s house at certain points was moderate, that the substation served a public convenience and was not removable without prejudice to customers, and that the company had acted in good faith regarding permits.

Evidence on Character and Intensity of Noise

The testimonial evidence describing the noise was numerous but in the Court’s view largely subjective and imprecise, with witnesses likening it to a humming, hissing, running motor, or distant airplane. The Court placed greater reliance on quantitative sound-level measurements. Dr. Jesus Almonte, under instruction of the Director of Health, recorded readings at points on the plaintiff’s property: on 27 August 1957 at 11:45 a.m., readings of 46–48 decibels under a sampaloc tree and 49–50 behind the kitchen; on 29 August 1957 at 6:00 a.m., 56–59 and 61–62 decibels respectively; on 7 September 1957 at 9:30 a.m., 74–76 decibels under the sampaloc tree; and on 8 September 1957 at 3:35 a.m., 70 decibels under the tree and 79–80 decibels near the kitchen. The ambient sound level of the locality minus the substation’s contribution was found to be 28–32 decibels. The company’s superintendent, Mamerto Buenafe, took additional measurements on 19 December 1958 showing readings of 55 and 54 decibels near the property line, 52 decibels near the sampaloc tree, 42–43 decibels outside near the concrete wall, and 76 decibels near the transformers.

Legal Standards from Precedent

The Court recited the established rule that noise may be an actionable nuisance when it injures the health or comfort of ordinary persons in the vicinity to an unreasonable extent. Citing authorities summarized in the record, including the principles in Tortorella v. Traiser & Co., Inc. and Kentucky & West Virginia Power Co. v. Anderson, the Court reiterated that the determinative test is whether property, health, or comfort are so injuriously affected that the loss goes beyond the reasonable inconveniences of proximity. The Court acknowledged locality and necessity as relevant but held that zoning or public convenience does not license every noise attendant to lawful activity.

Court’s Reasoning on Nuisance and Remedy

The Court found the objective decibel measurements decisive and concluded that the continuous, day-and-night noise constituted an actionable nuisance. It rejected the trial court’s reliance on subjective testimony alone and concluded that relocation of the substation was manifestly impracticable and prejudicial to the company’s customers. The Court held that Manila Electric Co. must, within ninety days from finality of the decision, either transfer the substation or take appropriate measures to reduce the noise at the property line between the company’s compound and the plaintiff’s property to an average of forty to fifty decibels, including installing a partition of sound-absorbent material in place of the interlink wire fence.

Findings on Causation, Mitigation and Damages

The Court recognized that plaintiff’s medical evidence, consisting of treating physicians’ testimony and related medical materials, preponderated over the company’s expert conjecture and established that sleep deprivation, irritation and tension due to the noise had weakened the plaintiff’s constitution and predisposed him to infection. Nevertheless, the Court found the monetary claims grossly exaggerated and held that several mitigating factors reduced recoverable damages: the noise was not shown to be the exclusive cause of plaintiff’s ailments, no household or neighbors were shown to have become ill, plaintiff’s financial worries and indebtedness were relevant, and plaintiff failed to mitigate damages as required by Article 2203 by remaining in the affected premises and not taking reasonable steps such as leasing the house for sleeping elsewhere. The Court disallowed claims for speculative shortening of life expectancy, exemplary damages, and the asserted large sums for moral and other damages.

Award and Costs

The Court awarded Pedro J. Velasco P20,000.00 as moderate and moral damag

Case Syllabus (G.R. No. L-18390)

Parties and Procedural Posture

Pedro J. Velasco was the plaintiff-appellant who filed Civil Case No. 1355 in the Court of First Instance of Rizal, Quezon City Branch seeking abatement of a nuisance and damages.
Manila Electric Company and its officers William Snyder, John Cotton, and Hermenegildo B. Reyes were the defendant-appellees as operator and owners of the substation.
Anastacio A. Agan, City Engineer of Quezon City, was sued as a co-defendant for alleged dereliction in permitting enforcement.
The trial court dismissed Velasco’s complaint and the plaintiff appealed directly to the Supreme Court prior to Republic Act 5440.
The Supreme Court rendered its decision on August 6, 1971, reversing in part and affirming in part the lower court.

Key Factual Allegations

Velasco purchased three adjoining lots in Diliman, Quezon City in 1948, sold two lots to Meralco, and built his residence on the remaining lot situated about ten to twenty meters from the substation.
Meralco constructed the substation in September to November 1953 without prior building permit or authority from the Public Service Commission as previously litigated in Meralco vs. Public Service Commission, 109 Phil. 603.
The substation served not less than 8,500 residential homes, over 300 commercial establishments and about 30 industries and had transformers rated at two units of 5,000 Kva each or higher with fan cooling.
The substation emitted a continuous humming or droning sound which was audible in the appellant’s house and surrounding area.
The appellee initially used a sawale wall and later an interlink wire fence along the property line adjoining Velasco’s lot.

Trial Evidence

Witness testimony describing the sound varied from “humming,” “high-pitched note,” and “like an approaching airplane” to a “running motor,” but testimony was often vague or biased.
Objective sound measurements by Dr. Jesus Almonte, under instruction of the Director of Health, showed readings on the plaintiff’s property ranging from 46-50 decibels at certain points and as high as 79-80 decibels near the kitchen at specified dates and times (Exhibit NN-7, b-f).
Readings near the property line by Meralco’s superintendent Mamerto Buenafe on 19 December 1958 recorded 52 to 55 decibels near the fence and up to 76 decibels near the transformers (Exhibit 13).
Technical charts in evidence established comparative decibel levels for familiar sounds and the ambient sound of the locality at 28 to 32 decibels (Exhibits 11-B, 12, 15-A).

Legal Issues Presented

Whether the continuous sound emitted by the Meralco substation constituted an actionable nuisance under Art. 694 of the Civil Code.
Whether Velasco proved causal connection between the noise and his claimed physical ailments and economic losses pursuant to Art. 2202.
Whether exemplary damages, moral damages, loss of earnings, and attorney’s fees were recoverable and in what amounts.
Whether Anastacio A. Agan, City Engineer, was solidarily liable for permitting or failing to abate the nuisance.
