The University of Louisville has filed an appeal to an attorney general’s ruling regarding an Open Records dispute with the American Civil Liberties Union.Last summer, the ACLU filed an Open Records request for materials related to the pending merger of U of L Hospital, Jewish/St. Mary’s Hospital System and Catholic Health Initiatives.U of L refused to turn over 13 e-mails, claiming they were preliminary in nature and exempt from the Open Records law, and that some of them were also protected by attorney/client privilege.The ACLU appealed to the attorney general, which ruled that four of the e-mails were not exempt from the request.U of L is now appealing that decision in Jefferson Circuit Court.The attorney general also ruled last month that the company that operates U of L Hospital is a public entity, which would make the merger subject to state approval.
