ALBANY, N.Y. (AP) — A GPS device placed on the family car of a state worker suspected of falsifying time sheets violated his constitutional right to privacy, a New York Civil Liberties Union lawyer told the state’s top court Wednesday.

Corey Stoughton said investigators didn’t get a warrant, labor department employee Michael Cunningham had no notice of the tracking device and it operated round-the-clock for 30 days, including a weeklong family vacation. The NYCLU’s lawsuit claims that was too intrusive to be justified by the limited warrant exception for searches of government employees.
