The Golden Globe-nominated actress Ashley Judd has filed a police report accusing her half-sister Wynonna Judd of attempting to track her car with a GPS device. According to a document filed with Tennessee's Franklin Police Department, Judd suspected that her country singing older sister had placed a GPS tracking device on her silver Mini Cooper to obtain information related to an "ongoing custody dispute," with her family.

An unnamed female driver of Ashley's automobile reportedly became suspicious and took to the car to garage where a mechanic located the device.  

According to reports, police determined the cellular tracking gadget was registered to a local Nashville private investigator, Janice Diane Swafford-Holt. A source tells FOX411 that it isn't the first time Wynonna Judd has worked with the investigator.

"This issue falls under Tennessee Code Annotated 39-13-606, covering Invasion of Privacy by Electronic Monitoring of a Motor Vehicle," says the wonderfully named Tennessee-based attorney Adam Dread, "It is considered a criminal act in Tennessee for a person to install or conceal an electronic monitoring device on a vehicle belonging to another without the owner's permission.The penalty for those caught violating this can include both jail time and a fine.  In addition to criminal charges, the person being 'spied on' can certainly sue the person (including private investigators) illegally tracking them for 'invasion of privacy.'"

For the moment, it appears as though no charges will be filed as Franklin police have deemed the case "inactive" pending further leads, "Nothing comes as much of a surprise with this family.You have to expect anything from them."

Representatives for both the Judd sisters as well as the Franklin Police Department did not respond to a request for further comment.
