WASHINGTON--(BUSINESS WIRE)-- The Federal Reserve overstepped its bounds by catering to banks instead of doing what Congress instructed in legislation reforming debit card swipe fees, attorneys for merchants argued yesterday in federal court.

“Congress was clear about setting reasonable debit swipe fees and ensuring greater competition among card networks. It’s also clear that the Fed ignored Congress,” said Doug Kantor, an attorney for the merchants who have sued the Federal Reserve in the U.S. District Court for the District of Columbia.
