G.R. No. 131723 - Manila Electric Co. vs. T.E.A.M. Electronics Corp.

Case Summary (G.R. No. 131723)

Factual Background

Petitioner supplied electric power to buildings occupied by respondents under separate Agreements for the Sale of Electric Energy covering accounts 09341-1322-16, 09341-1812-13 and 19389-0900-10. Respondent T.E.A.M. Electronics Corporation was formerly NS Electronics (Philippines), Inc. and National Semi-Conductors (Phils.); it was wholly owned by respondent Technology Electronics Assembly and Management Pacific Corporation. Ultra Electronics Instruments, Inc. leased the DCIM building from TEC under a five-year lease that was terminated by ejectment in February 1988.

Inspections and Allegations of Tampering

On September 28, 1987 petitioner conducted a surprise inspection of the meters at the DCIM building, witnessed by an Ultra representative, and prepared Service Inspection Reports alleging tampering and meter seals deformed. Petitioner later conducted an inspection of the NS building on April 24, 1988 and a scheduled inspection of the DCIM meters on June 7, 1988, claiming renewed tampering. Petitioner asserted a sudden drop in recorded consumption beginning February 10, 1986 and, on November 25, 1987, demanded payment of P7,040,401.01 for unregistered consumption covering February 10, 1986 to September 28, 1987.

Administrative Demand, Disconnection and Reconnection

TEC received the demand on January 7, 1988 and referred it to Ultra, which disputed the assessment as excessive. For failure to pay, petitioner disconnected the DCIM building on April 29, 1988. TEC sought reconnection from the Energy Regulatory Board, which ordered immediate reconnection; petitioner delayed compliance and reconnected only on October 12, 1988 after TEC paid P1,000,000.00 under protest. TEC also paid P280,813.72 under protest to avert disconnection of the NS building service.

Procedural History in the Regular Courts

TEC and TPC filed a complaint for damages against petitioner and Ultra in the Regional Trial Court of Pasig, docketed as Civil Case No. 56851. The parties agreed at pre-trial to three issues limited to (1) liability for the DCIM disconnection, (2) liability for the claimed differential billing of P7,040,401.01, and (3) entitlement to exemplary damages. Trial ensued and the RTC rendered judgment for the plaintiffs on June 17, 1992.

Trial Court Findings and Disposition

The RTC found petitioner’s evidence insufficient to prove TEC’s tampering. The court held that the deformed seal and an opening in a wire duct did not by themselves establish tampering, particularly where access to the transformer was limited to petitioner’s employees. The RTC concluded petitioner acted in bad faith in disconnecting DCIM’s power and denied petitioner’s claim for differential billing under the doctrine of equitable negligence. The RTC ordered both petitioner and Ultra jointly and severally to reimburse TEC actual damages of P1,000,000.00, awarded P280,813.72 to TEC, awarded P150,000.00 to TPC, and assessed moral, exemplary damages, attorneys’ fees and costs against petitioner.

Court of Appeals Ruling

The Court of Appeals affirmed the RTC decision, but modified the interest computation date and recharacterized the rental reimbursement award as P150,000.00 per month for five months, with legal interest from January 13, 1989. The appellate court agreed that petitioner was negligent in failing to discover defects earlier, in belatedly notifying TEC of inspection results, and in disconnecting power without prior notice.

Issues Presented to the Supreme Court

The petition to the Supreme Court raised primarily legal questions: whether TEC tampered with the meters; whether petitioner was entitled to differential billing and could collect it; whether petitioner bore the burden of proving deliberate tampering by TEC; whether TEC should be held liable for acts of its lessee Ultra; whether petitioner was negligent in notification; and whether petitioner was justified in disconnecting service without prior notice.

Scope of Review and Rule 45 Limitation

The Supreme Court emphasized that under Rule 45 it may entertain only questions of law and it is not a trier of facts. Factual findings of the trial court, especially those affirmed by the Court of Appeals, are binding. The petition sought a re-evaluation of factual findings concerning tampering, which the Court declined to undertake.

Analysis of Tampering Evidence and Consumption Patterns

The Court reviewed petitioner's evidence of three alleged tampering incidents and the asserted sudden drop in consumption starting February 1986. Examination of consumption records showed similar sudden drops in years before the period in question, undermining the claim that the drop was peculiar and unexplainable. Comparative billing figures before and after the September 1987 correction did not show a palpably drastic difference. The Court accepted the RTC’s view that Ultra’s explanation of business losses and reduced power use was a plausible non-tampering cause.

Re-Inspection, Reasonable Repair Duty and Negligence

The Court observed that if tampering was found both in September 1987 and in June 1988, the more reasonable inference was that the meters had not been effectively corrected after the first inspection. The Court cited precedent that utilities cannot allow defective meters to persist indefinitely and must exercise due diligence to repair apparatus and discover defects. Failure to remedy defects constitutes negligence by the utility and may forfeit amounts otherwise claimed from customers.

Differential Billing and Burden of Proof

Given the negative factual findings on tampering, the Court affirmed the denial of petitioner’s claim for differential billing. It reiterated the principle that a utility seeking differential billing must support the claim with competent proof capable of measurement and reasonable certainty.

Disconnection and Notice Requirement under P.D. No. 401 and Revised General Order No. 1

The Court reviewed P.D. No. 401, which penalized tampering and authorized inspections but did not expressly provide for differential billing or immediate disconnection. Utilities incorporated differential billing and disconnection clauses into service contracts and the Court had recognized their validity. However, such remedies were subject to a prior 48-hour written notice as provided by Section 97 of Revised General Order No. 1. The Court found that petitioner disconnected DCIM without issuing the required 48-hour written notice and without giving the notice of impending disconnection, thereby abusing the remedies and acting improperly.

Award and Return of Actual Payments Made Under Protest

The Court held that TEC sufficiently proved payment under protest of P1,000,000.00 and P280,813.72. With the finding of no tampering, these sums should be returned with interest as ordered by the Court of Appeals and consistent with controlling guidelines on actual damages and proof thereof.

Liability of Ultra for the P1,000,000.00 Payment

The Court found the appellate court’s imposition of solidary liability on Ultra and petitioner for P1,000,000.00 erroneous. Ultra’s promise to settle was expressly conditioned upon a finding of defect or tampering and did not admit liability. Absent proof of tampering, it was improper to hold the lawful occupant liable; petitioner alone received the sum and should bear liability for its return.

Award for Generator Rental and Modification

The Court accepted TEC’s proof of rental payments for a genera

Parties and Procedural Posture

Manila Electric Company filed a petition for review on certiorari under Rule 45 of the Rules of Court seeking reversal of the Court of Appeals decision in CA-G.R. CV No. 40282.
T.E.A.M. Electronics Corporation and Technology Electronics Assembly and Management Pacific Corporation were plaintiffs below and respondents in this petition.
Ultra Electronics Instruments, Inc. was impleaded as defendant below as lessee and occupant of the DCIM building during the covered period.
The Regional Trial Court, Branch 162, Pasig, rendered judgment on June 17, 1992 in Civil Case No. 56851 in favor of the plaintiffs and against the defendants.
The Court of Appeals affirmed the RTC decision by Decision dated June 18, 1997 and Resolution dated December 3, 1997, prompting the present petition.

Key Factual Allegations

TEC occupied the DCIM and NS buildings and held electric service accounts under Account Nos. 09341-1322-16, 09341-1812-13, and 19389-0900-10.
On September 28, 1987, petitioners' inspectors allegedly found tampering in two meters at the DCIM building and prepared Service Inspection Reports.
Petitioner demanded payment of P7,040,401.01 as differential billing for unregistered consumption from February 10, 1986 to September 28, 1987.
Ultra was in possession of the DCIM building during the relevant period under a lease but was ejected on February 12, 1988 by court order for lease violations.
Petitioner disconnected electrical service to the DCIM building on April 29, 1988 for nonpayment of the alleged differential billing.
TEC paid P1,000,000.00 under protest to procure reconnection on October 12, 1988 and paid P280,813.72 under protest to avert disconnection at the NS building.
Subsequent inspections on June 7, 1988 allegedly showed renewed tampering, and an earlier April 25, 1988 inspection at the NS building allegedly revealed meter defects.

Issues Presented

Whether the electric meters at TEC’s DCIM and NS buildings were tampered with as alleged by petitioner.
Whether, assuming tampering, TEC was liable for the differential billing as computed by Manila Electric Company.
Whether petitioner was justified in disconnecting electrical service to the DCIM building without prior notice.

Contentions of Parties

Manila Electric Company contended that the presence of shorting devices and deformed seals established deliberate meter tampering and entitled it to differential billing and disconnection remedies.
TEC and TPC contended that petitioner failed to prove tampering, that the disconnection was made in bad faith and without required notice, and that payments made under protest and rental expenses for a generator set were recoverable.
Ultra contended that its conditional offer to settle was not an admission of liability and that it should not be held jointly liable absent proof of tampering.

Statutory Framework

The controlling law at the time was P.D. No. 401, as amended, which penalized unauthorized connections and tampering and authorized inspections and criminal prosecution.
The remedies of differential billing and immediate disconnection were not expressly provided in P.D. No. 401 and derived from service contract stipulations subject to regulatory requirements.
Revised General Order No. 1, Section 97, required a 48-hour written notice prior to disconnection for nonpayment where the billing period covers a month or more.
Article 2208 of the Civil Code permitted recovery of attorneys’ fees when exemplary damages were awarded.

Trial Court Ruling

The RTC found petitioner's evi
