The Ninth District of the U. S. Court of Appeals covers Alaska, Arizona, California and Hawaii. Those judicial proceedings have been conducted in this courthouse since it opened on West Washington Street in 2000 after spending $123 million. The six-story, glass façade was designed by architect Richard Meier. The building’s namesake is Sandra Day O’Connor. She was an Arizona judge and Majority Leader of the State Senate. In 1981, she was appointed by President Ronald Reagan as the first woman U.S. Supreme Court Justice. O’Connor retired in 2006.
