Justice Stephen Breyer's retirement from the Supreme Court marks a historical transition point.
One of the great pragmatists in the court's history, Breyer is the last of President Bill Clinton's appointees to still be serving. And only Justice Clarence Thomas now remains from the centrist court that sat together for longer than any other configuration of justices in history.
That court was called the Rehnquist court for its chief justice, William Rehnquist, but it really reflected the judicial temperament shared by Breyer and Justice Sandra Day O'Connor. It was a body of nine that decided almost all major cases by finding five votes for a pragmatic consensus that lay somewhere between the aggressive liberalism of 1950s and 1960s and the incipient right-wing ascendance that is in evidence today.
Breyer's impending retirement after 28 years embodies the demise of the court's pragmatic personality, every bit as much as the likely decision to overturn the abortion-rights precedent Roe v. Wade this spring will signify the end of pragmatic jurisprudence.
Breyer's pragmatism infused everything he did before becoming a justice. It infused his jurisprudence. And it is now infusing his decision to retire, which he took with care. Having recently published a powerful book arguing for the court's institutional authority to be protected, Breyer is stepping aside so that the bare Democratic Senate majority can ensure that he is replaced by a like-minded successor. Would that the late Justice Ruth Bader Ginsburg had acted similarly.
To understand Breyer's pragmatism, start with his pre-judicial career as a law professor and public servant. Breyer's specialty was administrative law, but that arid description can obscure how important his work was. Breyer's primary contribution was to help redefine his entire area of law into a study of regulation, defined broadly.
The recognition that the government, through regulation, exercises this tremendous power requires deciding how it should do so, and how the courts should supervise the process.
For Breyer, the answer was that government regulators should make reasoned decisions using the tools of cost-benefit analysis. He recognized that people make the best decisions when they take active steps to measure the possible effects of their actions, and consider where they might go wrong.
