In a challenge to the Federal Trade Commission’s power to go after companies for data security breaches, lawyers for medical-testing company LabMD Inc. called the government’s allegations against it “far-reaching and ludicrous.”

Dinsmore & Shohl partner William Sherman II argued before chief administrative law Judge D. Michael Chappell on Tuesday that the FTC overreached when it sued LabMD in August 2013 for failing to protect consumer privacy in violation of Section 5 of the FTC Act.
