WASHINGTON, D.C.â(ENEWSPF)âOctober 12, 2010. Assistant Senate Majority Leader Dick Durbin (D-IL) released the following statement today after Minnesota-based TCF National Bank filed a lawsuit challenging the constitutionality of a Durbin-authored law regarding interchange fees. The bipartisan language passed as part of the Wall Street reform act, requires the Federal Reserve to determine if the current interchange fee structure is both âreasonable and proportionalâ to the real cost of processing a debit card transaction and allows small businesses to offer discounts to consumers when they use cash, checks or debit cards.
