The National Retail Federation today asked an appeals court to uphold a judge’s ruling that the Federal Reserve set its cap on debit card swipe fees far higher than intended by Congress and that the cap needs to be recalculated at a lower level. A three-judge panel of the U.S. Circuit Court of Appeals is scheduled to hold a hearing in Washington this morning on the Fed’s challenge of U.S. District Court Judge Richard Leon’s July ruling that the 21-cent cap that took effect in 2011 was too high. The ruling came in a lawsuit brought by NRF and other groups.
