15 U.S. Code § 77p - Additional remedies; limitation on remedies
Except as provided in subsection (b), the rights and remedies provided by this subchapter shall be in addition to any and all other rights and remedies that may exist at law or in equity.
Any covered class action brought in any State court involving a covered security, as set forth in subsection (b), shall be removable to the Federal district court for the district in which the action is pending, and shall be subject to subsection (b).
Notwithstanding subsection (b) or (c), a covered class action described in subparagraph (B) of this paragraph that is based upon the statutory or common law of the State in which the issuer is incorporated (in the case of a corporation) or organized (in the case of any other entity) may be maintained in a State or Federal court by a private party.
Notwithstanding any other provision of this section, nothing in this section may be construed to preclude a State or political subdivision thereof or a State pension plan from bringing an action involving a covered security on its own behalf, or as a member of a class comprised solely of other States, political subdivisions, or State pension plans that are named plaintiffs, and that have authorized participation, in such action.
Notwithstanding subsection (b) or (c), a covered class action that seeks to enforce a contractual agreement between an issuer and an indenture trustee may be maintained in a State or Federal court by a party to the agreement or a successor to such party.
The securities commission (or any agency or office performing like functions) of any State shall retain jurisdiction under the laws of such State to investigate and bring enforcement actions.
The term “affiliate of the issuer” means a person that directly or indirectly, through one or more intermediaries, controls or is controlled by or is under common control with, the issuer.
Notwithstanding subparagraph (A), the term “covered class action” does not include an exclusively derivative action brought by one or more shareholders on behalf of a corporation.
For purposes of this paragraph, a corporation, investment company, pension plan, partnership, or other entity, shall be treated as one person or prospective class member, but only if the entity is not established for the purpose of participating in the action.
The term “covered security” means a security that satisfies the standards for a covered security specified in paragraph (1) or (2) of section 77r(b) of this title at the time during which it is alleged that the misrepresentation, omission, or manipulative or deceptive conduct occurred, except that such term shall not include any debt security that is exempt from registration under this subchapter pursuant to rules issued by the Commission under section 77d(2)  of this title.
