Reuters – Bank of New York Mellon Corp must face a lawsuit seeking to hold it liable for causing $1.12 billion of investor losses by failing to properly monitor five trusts backed by toxic residential mortgages, a Manhattan federal judge ruled.

U.S. District Judge Gregory Woods said Belgium’s Royal Park Investments SA/NV may pursue claims that the bank, as trustee for trusts dating from 2005 to 2007, ignored widespread, systemic abuse in how the underlying loans were underwritten and serviced, and failed to require that bad loans be repurchased.

“Indeed,” Woods wrote in his decision on Wednesday, “it would be implausible to assume that somehow all of the mortgage loans underlying the trusts miraculously avoided the pervasive practices of the industry at the time.”

Royal Park contended that Bank of New York breached its duties in part out of fear it might anger or lose business from other financial services companies in retaliation.

Other Manhattan federal judges have within the final year let Royal Park pursue related claims against Deutsche Bank AG and HSBC Holdings Plc.

A spokesman for Bank of New York Mellon declined instant comment.

Royal Park has sought class-action status on behalf of other investors. It mentioned its own residential mortgage-backed securities in the 5 trusts overseen by Bank of New York Mellon have become “completely worthless.”

Bond issuers appoint trustees to ensure that payments are funneled to investors, and deal with back-office work after securities are sold.
