Whether a private plaintiff may recover damages under § 10(b) of the Securities Exchange Act and Rule 10b-5 based solely on the defendant’s negligence, without alleging scienter.
Holding
No. A private damages action under § 10(b) and Rule 10b-5 requires scienter—an intent to deceive, manipulate, or defraud—and cannot rest on negligent conduct alone.
Reasoning
The statutory text controls. Section 10(b) prohibits the use of a “manipulative or deceptive device or contrivance.” In ordinary usage, and especially in securities-law usage, those terms denote deliberate, knowing, or intentional misconduct rather than a mere failure to exercise reasonable care. The word “manipulative” in particular was a term of art for intentional practices designed artificially to affect securities prices or deceive investors.
The Court rejected the SEC’s and respondents’ argument that investor-protection purposes justified a negligence standard because negligent and intentional misconduct may cause the same injury. That effects-based reasoning would depart from the statutory language and could logically extend liability even further toward faultless conduct. Congress’s remedial goals cannot override words that plainly focus on deceptive and manipulative schemes.
The legislative history, while not explicit, reinforced the textual reading. The predecessor provision was described by a drafter as a catchall intended to let the SEC address new “cunning” or manipulative devices. That description gives no support to treating negligent omissions as prohibited devices or contrivances.
The structure of the 1933 and 1934 Acts also mattered. Congress specified different standards of fault in carefully drawn express remedies: strict liability in some contexts, negligence-based liability in others, and good-faith or willfulness protections elsewhere. For example, § 11 of the 1933 Act gives accountants and other experts a due-diligence defense, expressly creating a negligence-based framework. Congress did not use comparable language in § 10(b).
Allowing negligence claims under the judicially implied § 10(b) remedy would also permit plaintiffs to bypass the procedural limits Congress attached to express negligence-based actions, including shorter limitation periods and cost-bond provisions. The Court would not read an implied remedy so broadly that it effectively displaced those deliberate statutory restrictions.
Rule 10b-5 cannot enlarge the authority Congress gave the SEC under § 10(b). Although parts of Rule 10b-5, read alone, might arguably reach negligent misstatements or conduct that operates as a fraud, the Rule was adopted under § 10(b) and must remain within that provision’s scope. Its administrative history likewise showed that it was adopted to combat fraudulent conduct involving scienter.
The Court did not decide whether recklessness can satisfy scienter in some circumstances, whether scienter is required in SEC injunctive actions, or whether aiding-and-abetting liability is independently available under § 10(b) and Rule 10b-5. Those questions were unnecessary because respondents alleged only negligent nonfeasance.
