INTEREST OF AMICI CURIAE1
The Lawyers’ Committee for Civil Rights Under Law (“Lawyers’ Committee”) is a nonpartisan, non-profit civil rights organization founded in 1963, to secure equal justice for all through the rule of law, targeting the inequities confronting Black Americans and other people of color. The Lawyers’ Committee uses legal advocacy to achieve racial justice to ensure that Black people and other people of color have the voice, opportunity, and power to make the promises of our democracy real. The Lawyers’ Committee has worked extensively with local governments, private fair housing nonprofits, and community organizing groups to advance inclusionary zoning as a model policy for fostering inclusive, integrated communities that are free from discrimination and provide access for all residents, including Black families that have been subjected to discrimination. A decision in favor of Appellant would make it significantly more difficult and cost-intensive for state and local governments to promote affordable housing development through legislatively imposed impact or linkage fees and could deter the adoption of inclusionary zoning.
