O’Connor’s Most Vital Work Was After She Stepped Down

You can tell a lot about a person by what he or she regrets. This holds especially for Supreme Court justices, whose decisions can, with a single vote, upend individual lives and alter the course of history. Justice Lewis F. Powell Jr. said he probably made a mistake in upholding a law criminalizing gay sex; Justice Harry Blackmun was sorry he ever voted to impose the death penalty.

Justice Sandra Day O’Connor, who died on Friday at the age of 93, expressed regret publicly over one vote she cast: in the case of Republican Party of Minnesota v. White, a 2002 ruling that judicial candidates could not be prohibited from expressing their views on disputed legal and political issues. Minnesota, like many states that elect judges, had imposed such a ban in order to preserve the appearance of judicial impartiality. The court rejected the ban for violating the First Amendment. The decision was 5 to 4, with Justice O’Connor joining the majority.

The court’s ruling led to an explosion of partisan spending on judicial elections around the country and judicial candidates freely spouting their predetermined views on the very issues they would be entrusted to decide if elected.

There are many ways to remember Justice O’Connor — as the first woman on the Supreme Court, as one of the justices who saved Roe v. Wade 30 years ago, as the author of the landmark decision protecting affirmative action in 2003. As impressive as those achievements were, they have mostly been surpassed or reversed. What stands out for me is what she said and did after leaving the court.

Her response to the 2002 ruling would define most of her last years and underline her commitment to American democracy not just in the halls of justice but also on the ground. It was as if she could see what was coming as the judiciary grew ever more politicized, and she devoted much of her postcourt public life to combating that trend.

In March 2006, only weeks after she stepped down, she gave a speech calling out Republican lawmakers for attacking the judiciary. She highlighted the comment by Senator John Cornyn of Texas that deadly violence against judges might be related to their rulings.
