15 U.S.C. § 78aa–1 — Special provision relating to statute of limitations on private causes of action

(a) Suits already pending. For a private lawsuit implied under section 10(b) of this title (78j(b)) that was already filed on or before June 19, 1991, the deadline for filing (the "limitation period") is whatever period applied under that jurisdiction's law — including its rules on retroactivity — as that law stood on June 19, 1991. (b) Suits already dismissed. Take a private lawsuit under section 10(b) that was filed on or before June 19, 1991. If that suit (1) was later thrown out as filed too late, after June 19, 1991, and (2) would actually have been filed on time under the law described in subsection (a) (as it stood on June 19, 1991), then the suit must be reinstated — as long as the plaintiff asks the court to reinstate it within 60 days after December 19, 1991.
