Southern Burlington County NAACP v. Township of Mount Laurel (1975)
New Jersey's Supreme Court struck down Mount Laurel's zoning rules that excluded affordable housing, ruling that municipalities can't use land-use powers to keep out lower-income residents.
Mount Laurel was ordered to allow affordable housing; the doctrine expanded across New Jersey through the Fair Housing Act.
The Mount Laurel doctrine remains central to exclusionary land-use law, though many local governments still resist affordable housing mandates.
Nahant's documented 1960s fear of 'the wrong sort of people' raises the same concern — local power used to shape who can access a community. The SJC didn't rule on exclusionary intent, but the history hangs over the decision.
