Corporate Liability in Illegal Petroleum Trading: Defining the Scope of Responsibility

The Supreme Court's 2010 decision in Ty v. De Jemil (G.R. No. 182147) clarifies two critical points in the prosecution of illegal petroleum trading cases: first, that probable cause exists for unauthorized refilling of branded LPG cylinders and underfilling even of a single cylinder; and second, that not every corporate officer may be held criminally liable—only those specifically charged with managing the business. The ruling provides important guidance for corporations and their officers navigating the regulatory landscape of the LPG industry.

The Case: NBI Test-Buy and Search Warrants

The case began when NBI agents conducted surveillance and a test-buy operation against Omni Gas Corporation, an LPG refilling business in Pasig City. Agents brought eight branded LPG cylinders—Shellane, Petron Gasul, Totalgaz, and Superkalan Gaz—to Omni for refilling. The cylinders were refilled without LPG valve seals, and one was found underfilled upon inspection.

Subsequent search warrants led to the seizure of numerous branded LPG cylinders from Omni's premises, including cylinders marked as "Omnigas" but bearing embossed brand names of Shellane, Gasul, and Totalgaz. The NBI filed complaints against five stockholders of Omni, all of whom were members of the board of directors.

The Issue: Who May Be Held Criminally Liable

The central question was whether the corporate officers could be held liable under Batas Pambansa Blg. 33, as amended by Presidential Decree No. 1865, which penalizes illegal trading in petroleum products, including unauthorized refilling of branded cylinders and underfilling.

Probable Cause for Unauthorized Refilling

The Court found probable cause for violation of Section 2(a) in relation to Section 3(c) of BP 33, which prohibits the unauthorized refilling of another company's or firm's cylinders without written authorization. The certifications from Pilipinas Shell, Petron, and Total showed Omni had no written authority to refill their branded cylinders.

Significantly, the Court rejected the argument that ownership of the cylinders by customers negates liability. The law does not require the refiller to own the cylinders; what matters is the absence of written authorization from the brand owner. The Court noted that brand owners are deemed owners of their duly embossed cylinders even when possessed by consumers, citing DOE Circular No. 2000-05-007 and related issuances.

Underfilling: Even a Single Cylinder Constitutes a Violation

The Court likewise found probable cause for violation of Section 2(c) on underfilling. Contrary to the petitioners' argument that one underfilled cylinder was an isolated incident, the Court held that a single underfilling constitutes an offense. Citing Perez v. LPG Refillers Association of the Philippines, Inc., the Court affirmed that penalties may be imposed on a per-cylinder basis, as each violation falls within the scope of prohibited acts under Section 4 of BP 33.

The Limits of Corporate Liability

The Court then addressed the scope of criminal liability under Section 4 of BP 33, which enumerates liable persons: the president, general manager, managing partner, or such other officer charged with the management of business affairs, or the employee responsible for the violation.

Applying the principle expressio unius est exclusio alterius—the mention of one thing implies the exclusion of another—the Court held that mere members of the board of directors are not automatically liable. The board is generally a policy-making body, not directly engaged in day-to-day operations.

However, the Court made an exception for petitioner Arnel U. Ty, who was the President of Omni. As president, he was charged with managing the business affairs and therefore could be held liable. The charges against the other petitioners, who were directors but not operating officers, were dismissed.

Practical Takeaways

• Unauthorized refilling of branded LPG cylinders is illegal regardless of who owns the cylinders. A refiller must have written authorization from the brand owner, even if customers bring their own cylinders.
• A single underfilled cylinder can trigger criminal liability. The law does not require a pattern of deliberate underfilling; each violation is penalized separately.
• Not all corporate officers are automatically liable. Under BP 33, only the president, general manager, managing partner, or officers charged with managing business affairs—plus the responsible employee—may be held criminally liable.
• Corporate titles matter. A person's position as a director alone does not create criminal exposure; liability depends on actual management responsibility.
• The President of a corporation faces heightened exposure. As the chief operating officer, the president is presumed to manage business affairs and may be held liable for violations committed by the corporation.
