Consumers continue to take aim at credit card companies in court.
In August, a federal judge in Seattle certified as a class action a lawsuit against First USA, the credit card unit of Bank One. The rates were increased to as much as 30 percent. First USA is challenging the class action certification. Earlier this month, a class action suit was filed against Fleet Bank. The company is accused of false advertising and violating Rhode Island's Deceptive Trade Practices Act after it increased the APR on a credit card after less than a month.
