On February 3, Judge Alison Nathan of the United States District Court for the Southern District of New York largely denied Deutsche Bank National Trust Co.’s (the “Trustee’s”) motion to dismiss in a proposed class action brought by Royal Park Investments SA/NV over $3.1 billion in losses in residential mortgage-backed securities.  Royal Park alleged that the Trustee failed to require the loan sellers to repurchase or substitute loans when it became aware that the underlying mortgages were defaulting.  Judge Nathan rejected the Trustee’s argument that Royal Park failed to make a written demand to initiate a repurchase action as required in the trusts’ pooling and service agreements, holding that the Trustee had an obligation to provide notice to the other parties when it independently discovered breaches of representations and warranties.  Judge Nathan did, however, dismiss Royal Park’s derivative claims on behalf of 10 trusts that held the loans because the suit was direct rather than derivative in nature.  Order.
