"Today's judgment is a small step in the case but it is a significant leap for Australian bank customers," Mr Watson said.
"Late credit card fees are the bane of most people's existence. We know that many people rely on credit cards and the fees charged by the ANZ for late payment are exorbitant.
"This decision will be welcomed by mums and dads, small business owners and credit card holders everywhere.
"The fees we've won on, in relation to late payment on credit cards, are significant fees for bank consumers everywhere.
"You are late on the payment of the minimum amount and you get slugged with this ridiculous amount of money that bears no relationship to the fact you are a fraction late in the payment of whatever amount was due
"We will examine thoroughly the full judgment from Justice Gordon and it is likely we will appeal her decisions on the other fees and charges."
On 22 September, 2010 Maurice Blackburn issued proceedings in the Federal Court against in the ANZ bank in the first of a series of class actions against Australian banks for repayment of exception fees they have charged to their customers over the past six years.
Exception fees include honour and dishonour fees on bank accounts, as well as over limit fees and late payment fees on credit cards.
