Does Section 2(i) of the Federal Trade Commission Act apply retroactively?

⁷ Even if we considered the applicability of Section 2(i), our conclusion would not change. The most recent acts of the alleged manipulation described by Plaintiffs occurred in September 2012, before Section 2(i) became effective, and the provision is silent as to retroactive application. Bowen v. Georgetown Univ. Hosp. , 488 U.S. 204, 208, 109 S.Ct. 468, 102 L.Ed.2d 493 (1988) ("[C]ongressional enactments and administrative rules will not be construed to have retroactive effect unless their language requires this result.").
