Sept 16 (Reuters) - Australia"s securities regulator said on Thursday 30 criminal charges had been filed in the federal court against top lender Commonwealth Bank of Australia (CBA.AX) for mis-selling consumer credit insurance to its customers. The charges relate to promotion and sale of certain policies as an add-on insurance product, the Australian Securities and Investments Commission (ASIC) said. In April, the ASIC also sued no. 2 lender Westpac Banking Corp (WBC.AX) and alleged it sold consumer credit insurance to customers who had not agreed to buy it. ASIC said on Thursday the charges address allegations that between 2011 and 2015, CBA made false or misleading representations about benefits of the insurance policies to customers when some or all the benefits were not available.
