NEW ORLEANS - A Louisiana federal judge on May 2 declined to certify a class of grocery store consumers suing over the chain's failure to truncate credit card expiration dates on receipts after determining that a class action is not a superior method to adjudicate the case (Robert Ticknor, et al. v. Rouse's Enterprises, LLC, No. 12-1151, E.D. La.; 2014 U.S. Dist. LEXIS 61371).
