Justice Stephen G. Breyer’s Supreme Court chambers are not quite as grand as those he occupied before he retired in 2022, but they are still pretty nice. As before, they include a working fireplace, which was crackling when I went to visit him on a temperate afternoon in late February to talk about his new book.

In earlier interviews, Justice Breyer could be rambling and opaque. This time he was direct. He said he meant to sound an alarm about the direction of the Supreme Court.

“Something important is going on,” he said. The court has taken a wrong turn, he said, and it is not too late to turn back.

The book, “Reading the Constitution: Why I Chose Pragmatism, Not Textualism,” will be published on March 26, the day the Supreme Court hears its next major abortion case, on access to pills used to terminate pregnancies.

The book devotes considerable attention to Dobbs v. Jackson Women’s Health Organization, the 2022 decision that eliminated the constitutional right to abortion. Justice Breyer, who had dissented, wrote that the decision was stunningly naïve in saying it was returning the question of abortion to the political process.

“The Dobbs majority’s hope that legislatures and not courts will decide the abortion question will not be realized,” he wrote.
