A judge has dismissed a class action lawsuit against Blue Cross Blue Shield of New Jersey brought by four plaintiffs over a data breach at the health insurer, the New Jersey Law Journal reported.

Two laptops were stolen from Horizon's Newark office in November 2013. The plaintiffs, part of a proposed class consisting of more than 830,000 members, argued they were at risk of identity theft because the laptops contained sensitive information, including Social Security numbers.

But U.S. District Judge Claire Cecchi ruled that since there's no evidence any data was actually misused, the class had no standing. She also dismissed a claim of economic injury brought by three of the plaintiffs who argued that their premiums should have provided for the security of their personal information. Citing precedent, Cecchi dismissed that claim as well, writing that the plaintiffs failed to demonstrate actual economic harm as a result of the breach.

Cecchi granted Horizon's motion to dismiss March 31.
