The New Haven car rental company that tracked its customers with satellites and fined them for speeding has appealed an order to stop the practice and refund the money, Connecticut Attorney General Richard Blumenthal said Friday.

The state ordered Acme Rent-a-Car in February to stop using its global positioning system to track its customers’ speed, and to refund fines levied on nearly 30 people.

“Acme cannot infringe on the privacy rights of its customers or fine consumers with no recourse,” the attorney general said. “We will vigorously defend the state’s order.”

The company had charged its customers each time the global positioning system tracked them driving over 79 mph for more than two minutes. Consumer Protection Commissioner James T. Fleming has said Acme did not adequately inform customers about the policy.

Fleming also ruled that the $150 fines were penalties and illegal under the state’s fair trade practices law.

Acme attorney Max Brunswick did not immediately return a call for comment.
