An Arizona trailblazer: O’Connor’s remarkable career began here.

In 1971, while she was in the Arizona State Senate, Sandra Day O’Connor co-sponsored a bill that would change the way Superior Court judges were put on the bench.

At that time, all judges were elected. To take politics out of the court, O’Connor’s bill proposed that they be appointed by the governor for their merit after an indepth vetting process.

The bill failed.

She and her colleagues tried and failed again in 1973. And then O’Connor ran for Maricopa County Superior Court judge and won in 1974 – the same year that a citizens’ initiative passed, instituting merit selection in Arizona’s largest counties. (There is now merit selection in Maricopa, Pima and Pinal counties; the rest still elect judges).

O’Connor — who announced Tuesday that she has dementia — was a tough and demanding judge by all accounts.

“Sandra had a very good reputation,” said Mary Schroeder, who now sits on the 9th U.S. Circuit Court of Appeals and knew O’Connor from the days when they were both Arizona state judges. “She had a mind for detail,” and for that reason, the appellate judges counted on her to make a very complete record of the cases she tried.

Hattie Babbitt, who later became good friends with O’Connor, recalls being a young lawyer in front of her in Superior Court.

She recalls being intimidated because O’Connor expected a lot of lawyers.

Babbitt was also pregnant with her first child, and one day, when her hearing before O’Connor ended, O’Connor asked her to stay behind and gave her a lecture on how to manage a child and a law practice at the same time.

Babbitt recalled that, while sitting in on Supreme Court hearings years later, O’Connor spoke up and “I got nervous, and it was the same voice.”

Ruth McGregor, the former Arizona Supreme Court justice who was O’Connor’s first clerk at the U.S. Supreme Court said, “Her reputation was, if you’re going before Judge O’Connor, you’ve got to be prepared.”

She had to be stern, McGregor said: there were only three women on the bench, and they needed to show they meant business.

O’Connor was already known for her fairness.

“Her attitude both in the legislature and in person is that what mattered in life and in our democracy was respecting peoples’ rights,” said Alfredo Gutierrez, who served with her in the state senate, though as a Democrat.

O’Connor carried her experiences in state government with her for the rest of her career. She had been a lawyer in private practice, an Assistant Arizona Attorney General, a state senator, and the first female president of a state senate anywhere.
