A judge ordered the city to halt its rezoning of the Broadway Triangle in a ruling that came one day after the city approved the controversial project.

The decision by Justice Emily Jane Goodman of the State Supreme Court in Manhattan followed a lawsuit filed by a community coalition opposed to the city's plan to rezone a 31-acre swath of Williamsburg to make way for housing.

The rezoning would make way for the development of 1,851 apartments, nearly half of which would be set aside for lower and middle-income people. The Williamsburg site, bounded by Throop, Flushing, Harrison and Union avenues and Lynch Street, also borders the neighborhoods of Bushwick and Bedford-Stuyvesant..

All three areas are short on affordable housing, according to the Broadway Triangle Community Coalition (BTCC), which filed the lawsuit that swayed Judge Goodman to temporarily block the rezoning from moving forward.

The lawsuit claims the planning process for the rezoning was secretive and discriminated against minority groups, including Hasidic Jews, Latinos and blacks, who would stand to benefit from the new housing built there.

BTCC favors a rezoning to accommodate nearly 5,000 apartments, with a 75 percent affordability component.

In a statement, Marty Needelman, an attorney representing BTCC, said “it is truly sad that until we got to the court, no governmental agency was willing to overrule the politics of the situation.”

He said the lawsuit would address the “shocking racially and religiously discriminatory result incorporated into the city’s proposed rezoning.”

Juan Ramos, BTCC's chairman, said the rezoning represented yet another example of the city’s “long history of outrageous racial and religious discrimination in Williamsburg.”

The injunction halting the rezoning could remain in effect until a new hearing on the issue in March, according to lawyers involved with the lawsuit.
