Jan 22 (Reuters) - Australian law firm Maurice Blackburn said on Wednesday it has filed a class action lawsuit on behalf of more than 330,000 account holders against two entities of National Australia Bank NAB.AX for alleged breaches in pension laws.
Maurice Blackburn alleged that the two entities, MLC Nominees Pty Ltd and NULIS Nominees (Australia) Ltd, kept account holders in products with higher fees and commissions.
NAB did not immediately respond to a request for comment outside regular business hours.
The lawsuit was filed in the Victorian Supreme Court. "This is another regrettable case of mismanagement in the superannuation sector," said Andrew Watson, national head of class actions at the law firm.
He said the lawsuit would centre on "NAB's failure" to transition more than A$6.3 billion ($4.31 billion) of default member balances to a lower cost product in a timely manner.
Last month, Australia's securities regulator took the country's third largest lender to court, accusing it of inappropriately taking fees from financial planning customers. "Big Four" banks are bracing for another year of pain after a string of scandals and damaging revelations from a government-backed inquiry into financial sector misconduct.
