Northeastern University law expert Daniel Urman remembered the late Sandra Day O’Connor — the first woman to serve on the Supreme Court — as a trailblazing historical figure and powerful swing vote whose independent streak and pragmatism would make her unlikely to be nominated to the high court today.

“In a way, O’Connor’s legacy is that she became for conservatives an example or a warning sign of what happens if you don’t nominate a movement conservative,” said Urman, director of the law and public policy minor at Northeastern, who teaches courses on the Supreme Court. 

“Her virtues as a pragmatist, independent thinker and minimalist, were definitely seen by others as vices — she probably wouldn’t be nominated today, because she would be seen as too much of a wild card,” he said.

O’Connor died at age 93 on Friday in Phoenix. The Supreme Court said the cause was complications of dementia.

President Ronald Reagan nominated O’Connor to the Supreme Court in 1981, fulfilling a campaign promise to appoint the first female justice. 

At the time, O’Connor was a judge on a mid-level appeals court in Arizona, the state where she grew up on a remote cattle ranch and where she spent most of her life. O’Connor was also involved in Arizona Republican politics. She spent five years in the Arizona Senate, winning two re-election campaigns, and became majority leader in 1972. No woman in the country had held such a high office in a state legislature.

O’Connor continued to wield tremendous power as a justice, a role she held for 24 years before retiring in January 2006 to care for her ailing husband. 

“In the ’80s and ’90s, really during her entire time on the Supreme Court, she was not only the most powerful woman in America, but also a really powerful justice who often cast tie-breaking votes in major cases,” Urman said. 

In fact, it was as this tie-breaking vote that O’Connor repeatedly disappointed conservative critics. 

O’Connor wrote the majority opinion to uphold the use of race in admissions at the University of Michigan in the 2003 case, Grutter v. Bollinger. She also was unwilling to overturn Roe v. Wade when given the opportunity in the 1992 case, Planned Parenthood v. Casey. 

“These were the top priorities for the legal right,” Urman said. “They basically saw (O’Connor) as the reason we had legal abortion and affirmative action as long as we did.”
