HELENA, Mont. -

Diane Barz, the first woman to serve on the Montana Supreme Court, has died. She was 70.
    
Michelotti-Sawyers Mortuary in Billings says Barz died Wednesday after a nearly 8-year battle with cancer.
    
Barz was the only woman in the University of Montana law school's graduating class of 1968 and with Doris Poppler formed the first women's law firm in the state.
    
She was the first woman and youngest person elected a District Court judge in Montana and was the first woman to serve on the Montana Supreme Court. Court Clerk Ed Smith says she was appointed in 1989 and resigned in 1990 because her family wasn't living in Helena. She retired in 2003.
    
A memorial service is scheduled for May 28 at First Presbyterian Church in Billings.
