Any person who shall make or cause to be made any statement in any application, report, or document filed with the Commission pursuant to any provisions of this subchapter, or any rule, regulation, or order thereunder, which statement was at the time and in the light of the circumstances under which it was made false or misleading with respect to any material fact, or who shall omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, shall be liable to any person (not knowing that such statement was false or misleading or of such omission) who, in reliance upon such statement or omission, shall have purchased or sold a security issued under the indenture to which such application, report, or document relates, for damages caused by such reliance, unless the person sued shall prove that he acted in good faith and had no knowledge that such statement was false or misleading or of such omission. A person seeking to enforce such liability may sue at law or in equity in any court of competent jurisdiction. In any such suit the court may, in its discretion, require an undertaking for the payment of the costs of such suit and assess reasonable costs, including reasonable attorneys’ fees, against either party litigant, having due regard to the merits and good faith of the suit or defense. No action shall be maintained to enforce any liability created under this section unless brought within one year after the discovery of the facts constituting the cause of action and within three years after such cause of action accrued.
