ADDITIONAL CASESUnited States of America, Plaintiff-Intervenor v. Metropolitan Transportation Authority and New York City Transit Authority, DefendantsOPINION & ORDER Before the Court are cross motions for partial summary judgment. Plaintiffs — two non-profit advocacy organizations and two disabled individuals who represent a class of similarly situated individuals — move for summary judgment seeking a determination that the replacement of the stairways at the Middletown Road Subway Station in the Bronx triggered certain accessibility requirements under 49 C.F.R. §37.43(a)(1). Defendants, Metropolitan Transportation Authority (“MTA”), the New York City Transit Authority (“NYCTA”), and their chief executives move for summary judgment seeking a determination that the applicable regulation is 49 C.F.R. §37.43(a)(2), not (a)(1). The distinction matters because under §37.43(a)(1), Defendants must make certain alterations to increase accessibility no matter the cost, while under §37.43(a)(2), Defendants must make such alterations only if doing so would not be disproportionately expensive.For the reasons set forth below, Plaintiffs’ motion for summary judgment is GRANTED and Defendants’ motion for summary judgment is DENIED.I.
