Electric Cooperative Liable for Injuries from Uninsulated High-Voltage Wires

Agusan del Norte Electric Cooperative, Inc. v. Balen (G.R. No. 173146, November 25, 2009) is a landmark Philippine tort case affirming that electric cooperatives owe a high duty of care to the public. The Supreme Court held ANECO liable for electrocution injuries caused by its uninsulated high-voltage wires strung over a private residence, even though the wires met minimum clearance requirements.

The Facts

In 1981, ANECO installed an electric post in Purok 4, Ata-atahon, Nasipit, Agusan del Norte, running a 13,000-volt main distribution line over the residence of Angelita Balen. Balen's father, Miguel, protested the installation to both the District Engineer's Office and ANECO, but his complaints were ignored.

On July 25, 1992, Balen, Hercules Lariosa, and Celestino Exclamado were electrocuted while removing a television antenna from Balen's residence. The antenna pole touched ANECO's main distribution line. Exclamado died instantly; Balen and Lariosa suffered extensive third-degree burns.

The victims sued ANECO for damages. The Regional Trial Court ruled in their favor, and the Court of Appeals affirmed. ANECO appealed to the Supreme Court, arguing that the victims' own negligence in handling the antenna was the proximate cause of the accident.

The Issue

Was ANECO negligent and therefore liable for the injuries, or were the victims' actions in taking down the antenna the proximate cause of their electrocution?

The Ruling

The Supreme Court denied ANECO's petition and affirmed the lower courts' decisions. The Court defined negligence as "the failure to observe for the protection of the interests of another person that degree of care, precaution, and vigilance which the circumstances justly demand."

Applying the foreseeability test, the Court found that ANECO should have reasonably foreseen that even with compliant clearance, uninsulated high-voltage wires over a residence posed a serious electrocution risk. The Court emphasized several key points:

• The house existed before ANECO installed the wires above it.
• The wires were open, uninsulated, and charged with 13,200 volts.
• ANECO failed to show any compelling reason for running the line over the Balen residence.
• ANECO did not put up the precautionary sign "WARNING-HIGH VOLTAGE-KEEP OUT" required by the Philippine Electrical Code for wires over 600 volts.
• Miguel Balen's prior complaints went unheeded.

The Court rejected ANECO's argument that the 11-year gap between installation and the accident mitigated its liability, citing Benguet Electric Cooperative, Inc. v. Court of Appeals (378 Phil. 1137 [1999]), which held that leaving an open live wire unattended for years "demonstrated utter disregard for the safety of the public."

The Legal Principles

The case clarifies two important doctrines. First, compliance with technical clearance requirements does not automatically absolve a utility from liability. The Court stated that meeting the Philippine Electrical Code's clearance standards "does not suffice to exonerate it from liability" when other safety measures—like insulation and warning signs—are absent.

Second, the Court reiterated that proximate cause is "any cause that produces injury in a natural and continuous sequence, unbroken by any efficient intervening cause, such that the result would not have occurred otherwise." Here, the victims' act of taking down the antenna would not have caused electrocution but for ANECO's negligent installation of live wires over the roof.

Practical Takeaways

• Electric cooperatives and utilities must do more than meet minimum clearance rules; they must use insulated wires or route high-voltage lines away from populated areas, and install required warning signs.
• Complaints from affected property owners should be taken seriously and documented; ignoring them can strengthen a later finding of negligence.
• Compliance with codes is not a complete defense—courts will look at whether the utility reasonably foresaw risks to public safety.
• Victims of electrocution or similar utility accidents may recover actual damages (hospitalization, lost income), moral damages, exemplary damages, attorney's fees, and litigation costs.
• The passage of time between installation and an accident does not mitigate a utility's liability; it may even aggravate it by showing continued neglect.
