The New Jersey Supreme Court is deciding whether to reinstate a $2.6 million award against car dealership owners for their employees’ theft of customer information from their former employer, a rival dealer.

The suit charges that Kate Fair, Timothy Morgan and Diane Kennedy quit Fairway Dodge of Ridgewood, N.J., to join Decker Dodge of Hawthorne, N.J., then snuck back into their old offices, hacking computers and harvesting customer lists of hundreds of names.
