The New York Sun reports today on a lawsuit that's been filed to try to block the Whitney's expansion. "The plaintiffs — two associations of residents and the owners of the Carlyle Hotel — claim that the Board of Standards and Appeals erred in granting the museum variances to zoning regulations, in order to allow the Whitney to go forward with its expansion, which includes a 178-foot stainless-steel-clad tower designed by the award-winning architect Renzo Piano."
UPDATE: The Gothamist has more.
