My colleague Karen Freifeld was in Manhattan State Supreme Court Thursday when Bank of America counsel Theodore Mirvis of Wachtell, Lipton, Rosen & Katz stood up to argue for the dismissal of Walnut Place’s suit demanding millions of dollars in put-backs in two Countrywide mortgage-backed securities trusts. Everyone who follows MBS litigation knows that Walnut, represented by Grais & Ellsworth, is the leading objector to BofA’s embattled $8.5 billion settlement with Countrywide MBS investors. But Freifeld was the first journalist to pick up Mirvis’s big disclosure: Walnut Place, he told Justice Barbara Kapnick, is actually the distressed debt hedge fund Baupost.
