A federal judge has cleared a lawsuit accusing the Wall Street giant Morgan Stanley of encouraging the targeting of African-American homeowners in Detroit. The plaintiffs in the case include five black Detroit residents who say Morgan Stanley helped subprime mortgage lender New Century Mortgage Company issue loans likely to push borrowers into foreclosure. In his ruling, U.S. District Judge Harold Baer tied Detroit’s current bankruptcy woes to the actions of major banks, writing: “It is not difficult to conclude that Detroit’s current predicament, at least in part, is an outgrowth of the predatory lending at issue here.”
