HARTFORD, Conn. (AP) Connecticut's highest court has ruled on an issue that most people may think is already settled, saying doctors have a duty to keep patients' medical records confidential and can be sued if they don't.

The Supreme Court's 6-0 decision Thursday overturned a lower court judge who said Connecticut had yet to recognize doctor-patient confidentiality.

The high court's ruling reinstated a lawsuit by former New Canaan resident Emily Byrne against the Avery Center for Obstetrics Gynecology in Westport.

Byrne, who now lives in Montpelier, Vermont, alleged the doctor's office sent her medical file to a court without her permission allowing the father of her child to look at it and use the information to harass her.

The Avery Center argued there is no duty for doctors to keep patients' information confidential.

This story corrects the summary to say the father of Byrne's child was able to view Byrnes' medical file, not the husband of her child.
