Piercing the Corporate Veil
Sonora Diamond Corp. v. Superior Court (2000) 83 Cal.App.4th 523
The rule
Piercing the veil requires (1) a unity of interest and ownership between the corporation and its shareholders such that separate personalities do not in reality exist, and (2) that treating the acts as those of the corporation alone would sanction fraud or promote injustice. Undercapitalization, commingling, and disregard of formalities are key factors.
In plain English
Piercing the corporate veil allows courts to hold shareholders personally liable for a corporation's debts if the corporation is merely an extension of the shareholders and not a separate entity. This typically occurs when there is a significant overlap in ownership and control, and ignoring the corporate structure would result in unfairness or fraud.
Worked example
A small business owner, Jane, runs her corporation from her home, using personal funds for business expenses and failing to keep separate financial records. When the corporation incurs significant debts, creditors seek to hold Jane personally liable. The court finds that Jane's actions justify piercing the corporate veil due to her commingling of assets and disregard for corporate formalities, making her liable for the debts.
Memory hook
Don't let the corporate shield become a fraud shield!
The trap
Exams often present scenarios where students must distinguish between legitimate corporate practices and those that suggest a lack of separation between the corporation and its owners. Students may overlook key indicators of commingling or undercapitalization.
How examiners test it
Questions typically involve fact patterns where the corporate structure is misused, prompting students to analyze whether the circumstances justify piercing the veil based on the unity of interest and potential injustice.
