Heading: Requirement or prohibition ... imposed under State law.

Text: 57 Although members of the Cipollone Court disagreed over whether a state common-law damages action could constitute a requirement under § 1334(b), the Court unanimously agreed that positive enactments are state-imposed requirement[s] or prohibition[s] within the meaning of that clause. See 505 U.S. at 521, 112 S.Ct. at 2620 (plurality opinion); 505 U.S. at 525, 112 S.Ct. at 2622 (Blackmun, J., concurring in part, dissenting in part); 505 U.S. at 548, 112 S.Ct. at 2634 (Scalia, J., concurring in part, dissenting in part). The Disclosure Act, being a positive enactment by the Massachusetts state legislature, therefore constitutes a state-imposed requirement that falls within the universe of state action potentially preempted by the § 1334(b). 22 58
