The bondholders filed a complaint on Friday against Deutsche Bank as the trustee for $3.6 billion (2.15 billion pounds) of principal of defaulted notes.

"This is really a dispute between two bondholder groups that is pending before Brazilian courts," Deutsche Bank said in a statement. "We believe this suit is without merit, and Deutsche Bank intends to vigorously defend itself."

The bonds were issued by an Austrian subsidiary of Oleo e Gas, a company formerly known as OGX that filed for Latin America's largest-ever bankruptcy in October.

The plaintiffs alleged that Deutsche Bank and affiliates "have made or will make grossly disproportionate distributions" to majority bondholders", according to a statement from the plaintiff's firm, Brown Rudnick LLP.

The bank said, however, that it had "fulfilled all of its duties, including regularly keeping bondholders notified of all changes and updates to their notes".

Plaintiffs include Capital Ventures International of the Cayman Islands, GLG Partners LP of London, Brennus Asset Management and VR Global Partners L.P.
