Late last month, without any fanfare, a New York appeals court issued a terse, one-page ruling that upheld the dismissal of Walnut Place’s breach-of-contract suit against Countrywide, Bank of America and Countrywide’s mortgage-backed securitization trustee, Bank of New York Mellon. It was an abrupt end for what was once a promising attempt at vindication for an MBS investor. It was also a huge setback for Walnut, its lawyers at Grais & Ellsworth and all the other Countrywide MBS investors who were counting on litigation against BofA as an alternative to the bank’s proposed $8.5 billion global settlement of breach-of-contract, or put-back, claims.
