Hannaford Bros. Class Action Suit 

Judge D. Brock Hornby conferred for the first time Monday with two competing groups of lawyers that are seeking to lead one of the nation’s largest data breach lawsuits.

The suit will seek compensation for customers who lost money or suffered stress or inconvenience after the supermarket chain announced in March that 4.2 million credit and debit card numbers were exposed to computer hackers.

Hornby will also set a schedule for how the case will proceed. One group competing for the lead role consists of firms in Portland and New York City. The other includes firms in Chicago, Miami, Philadelphia and Boston.
