Piercing the Corporate Veil

Piercing the corporate veil (sometimes called "lifting the veil") is an equitable exception to the foundational principle that a company is a legal person distinct from its owners — a principle established in English law by Salomon v A Salomon & Co Ltd [1897] AC 22. When the corporate form is abused to evade existing obligations, perpetrate fraud, or shield wrongdoers, courts may set the separateness aside and reach the shareholders, directors, or a parent company directly.

The doctrine is narrow and exceptional. In the United Kingdom, the Supreme Court in Prest v Petrodel Resources Ltd [2013] UKSC 34 confined veil-piercing to cases of "evasion," where a person under an existing legal obligation deliberately interposes a company to frustrate enforcement. In the United States, courts apply multi-factor tests (often traced to Berkey v Third Avenue Railway and elaborated in cases like Walkovszky v Carlton, 18 NY 2d 414 (1966)), looking at undercapitalisation, commingling of assets, failure to observe corporate formalities, and use of the entity as an "alter ego" or "instrumentality."

In international and political-economy contexts, veil-piercing matters for:

• Human rights and environmental litigation against multinational parents for subsidiary conduct abroad — see Vedanta Resources plc v Lungowe [2019] UKSC 20 and Okpabi v Royal Dutch Shell plc [2021] UKSC 3, which actually turned on the parent's own duty of care rather than veil-piercing strictly, but are often discussed alongside it.
• Sanctions enforcement, where regulators look through shell companies to identify beneficial owners.
• Investor–state arbitration, where tribunals occasionally disregard corporate structure to prevent treaty abuse or "nationality shopping."

Most jurisdictions treat the doctrine as a remedy of last resort, available only when ordinary contract, tort, agency, or statutory remedies cannot reach the real wrongdoer.
