A New England environmental nonprofit and a dozen condominium complex residents have filed separate lawsuits alleging the Commonwealth of Massachusetts illegally approved a city zoning plan allowing for construction of a 600-ft tower and other structures on the Boston Harbor.

The Conservation Law Foundation suit challenges Massachusetts Secretary of Energy and Environmental Affairs Matthew Beaton's approval of the city's Downtown Waterfront Municipal Harbor Plan—which covers about 42 acres of flowed and filled tidelands on the waterfront in downtown Boston—and the municipal harbor planning process. It claims the state ignored laws and processes put in place to ensure public rights on the waterfront.
