Case Summary (G.R. No. 165622)

Factual background

Respondent Judge De Leon experienced left-eye irritation on the evening of October 17, 1999 and consulted a physician-friend, Dr. Charles Milla, who prescribed “Cortisporin Ophthalmic” (eye drops) and “Ceftin.” The next morning De Leon went to Mercury Drug’s Betterliving branch, presented the prescription to pharmacist assistant Ganzon, paid for and received the medicine handed to him. At his chambers, his sheriff instilled 2–3 drops in De Leon’s left eye; the drops caused searing pain. Only after rinsing and sustaining the pain did De Leon discover he had been given “Cortisporin Otic Solution” (ear drops) instead of the prescribed ophthalmic preparation.

Immediate aftermath and merchant response

De Leon returned to the Mercury Drug branch with a still-irritated eye and confronted Ganzon. Ganzon admitted inability to fully read the prescription; the supervisor later apologized and said they lacked stock of the ophthalmic preparation. De Leon wrote to Mercury Drug’s president but received no substantive written response; instead, two salespersons visited his office and informed him the supervisor was busy. Dissatisfied with the lack of explanation and apology, De Leon sued Mercury Drug and Ganzon for damages.

Defendants’ contentions at trial

Mercury Drug and Ganzon denied negligence and contended that De Leon’s own negligence was the proximate cause of his injury because he failed to read the medicine label or instruct his sheriff to do so before instillation. They also argued that no Philippine product called “Cortisporin Ophthalmic” existed, that the prescription read “Cortisporin Solution,” and that Ganzon dispensed the only “Cortisporin Solution” available. Ganzon claimed she served De Leon because he was a regular customer, and the piece of paper presented lacked required prescription particulars (doctor’s name and license number).

Trial court (RTC) disposition and rationale

The RTC found for De Leon, awarding pecuniary loss equal to the medicine’s value (Php 153.25), moral damages of Php 100,000, exemplary damages of Php 300,000, and attorney’s fees of Php 50,000 plus litigation expenses. The RTC held that the proximate cause was Ganzon’s negligent exercise of her discretion in dispensing drugs — she dispensed without a proper prescription, did not fully read the prescription, and presumed the buyer accepted the ear preparation. The court applied the presumption of employer liability for an employee’s negligence and emphasized that drug dispensers owe a high degree of care.

Court of Appeals disposition and procedural basis

Mercury Drug and Ganzon appealed to the Court of Appeals (CA). De Leon moved to dismiss the appeal on procedural grounds. The CA granted the motion and dismissed the appeal pursuant to Section 1(f), Rule 50 of the 1997 Rules of Civil Procedure, finding the appellants’ brief lacked the required page references to the record as mandated in Section 13 of Rule 44. The CA denied the appellants’ motion for reconsideration, refusing to relax procedural rules absent faithful compliance and distinguishing precedents where briefs substantially complied.

Issues raised before the Supreme Court

Petitioners assigned errors to the CA: (1) that the CA erred in dismissing the appeal in view of cases allowing relaxation of technical noncompliance; (2) that the CA abused discretion by dismissing despite substantial compliance with Rule 60 and Rule 44 (presumably meaning the appellate rules); and (3) that the CA favored technicality over substantial justice, resulting in grave injustice and prejudice.

Supreme Court’s analysis on procedural dismissal and substantial compliance

The Supreme Court treated dismissal under Rule 50 as discretionary (the rule uses “may”), and reiterated that courts must exercise sound discretion sensitive to justice and fair play. The Court emphasized the two-fold importance of the appellant’s brief: to present issues coherently and assist the appellate court. While absence of page references is a ground for dismissal, it is not invariably fatal where the brief’s citations enable the court to expeditiously locate record portions. The Court compared the instant case to controlling authorities: unlike De Liano and Heirs of Palomique — where briefs lacked subject index, statement of facts, or other critical elements and the appellants failed to cure defects — the petitioners here referenced exhibits, transcript of stenographic notes, and attachments, enabling substantial compliance. Accordingly, the CA’s rigid dismissal on the procedural lapse was unwarranted as an automatic or mandatory sanction in the circumstances.

Supreme Court’s analysis on substantive liability and standards of care for pharmacies

On the merits, the Court reiterated established law that pharmacy practice demands the highest degree of care and skill; a mistake in dispensing drugs is negligence and the most dangerous kind of mistake. The Court cited local and foreign precedents (e.g., Tombari, Fleet, Smith’s Adm’x, United States v. Pineda, Mercury Drug v. Baking) to underscore that a druggist cannot escape liability by characterizing a substitution or misdispensation as an innocent mistake. Where injury is caused by an employee’s negligence, a legal presumption arises of the employer’s negligence in selection or supervision, which may be rebutted only by showing the exercise of the care of a good father of a family. The Supreme Court found Mercury Drug and Ganzon failed to rebut that presumption, noting that the dispensation of ear drops instead of prescribed eye drops constituted gross negligence in the context of the drugstore’s public interest function and the reliance cust
