WASHINGTON (AP) — The National Retail Federation is opposing a proposed $7.25 billion settlement that Visa Inc., MasterCard Inc. and major banks have agreed to pay retailers for alleged fee fixing.

The retail trade association said Tuesday that its board has given approval for it to go to court to try to block the settlement. It says it is unsure whether outside groups will be allowed to intervene or if the case qualifies as a class action.

The NRF says it believes the proposed settlement will not stop swipe fees from continuing to rise, which will hurt both retailers and shoppers, and that it will prevent any future legal challenges.

In July Visa, Mastercard and the banks settled a lawsuit that claimed card issuers conspired to fix merchants' fees for accepting credit cards.
