The American Civil Liberties Union and a Brooklyn-based advocacy group, the Center for Popular Democracy, have filed a Freedom of Information Act claim against the Federal Housing Finance Agency demanding that the regulator produce all agency records pertaining to the use of eminent domain to purchase mortgages. Filed in the U.S. District Court for the Northern District of California, the lawsuit seeks information regarding the FHFAs relationship with big banks and mortgage-backed securities investors and whether such interests influenced the agencys opposition. The suit was filed earlier this month on behalf of community housing advocates in California, New Jersey and New York.
