Trevor Maxwell of the Portland Press Herald reports:
A federal judge said he will decide in the next few days whether supermarket giant Hannaford Bros. is potentially liable for damages because of a data breach that exposed more than 4 million credit and debit card numbers to computer hackers.
Judge D. Brock Hornby heard arguments on Wednesday at U.S. District Court. Attorneys for Hannaford asked the judge to dismiss the lawsuit, which was filed against the Scarborough-based company last year. Attorneys for the plaintiffs said Hornby should certify the case as a class-action suit and let it proceed toward trial.
