Whether CERCLA makes a parent corporation derivatively liable for its subsidiary’s ownership or operation of a polluting facility merely because the parent controls the subsidiary.
Holding
No. A parent is derivatively liable for a subsidiary’s CERCLA obligations only when the corporate veil may properly be pierced under applicable corporate-law principles.
Reasoning
CERCLA imposes liability on a “person” who owned or operated a facility, but it does not expressly discard the settled rule that a parent and subsidiary are separate legal entities. Stock ownership ordinarily gives a parent significant control rights, including the right to elect directors, without making the parent liable for the subsidiary’s debts or torts.
Congress legislated against this established background of limited liability. Because CERCLA does not directly address when corporate separateness should be disregarded, the Court would not infer a broad statutory abrogation of ordinary corporate-law rules from congressional silence.
Traditional veil piercing remains available when the corporate form has been misused for an improper purpose, such as fraud. When veil piercing is justified, the parent may be held derivatively liable for the subsidiary’s CERCLA liability, including liability as an operator. The Court did not decide whether state law or federal common law supplies the veil-piercing standard, because that question was not presented.
