Dura Pharmaceuticals v. Broudo: The Unlikely Tort Of “Securities Fraud”: Dura Pharmaceuticals v. Broudo

Created pursuant to section 10 of the 1934 Securities Act, Rule 10b-5 is a cornerstone of the federal securities laws.

Elements of the rule, such as scienter and reliance, were defined at length by earlier court decisions.
