"Kelo" became the focus of vigorous discussion and attracted numerous supporters on both sides. Some 40 "amicus curiae" briefs were filed in the case, 25 on behalf of the petitioners. Susette Kelo's supporters ranged from the libertarian Institute for Justice (the lead attorneys on the case) to the NAACP, AARP, the Southern Christian Leadership Conference and South Jersey Legal Services. The latter groups signed an amicus brief arguing that eminent domain has often been used against politically weak communities with high concentrations of minorities and elderly.
