Of course, the idea for limited judicial tenures is hardly a new one; it was debated at the founding. Back then, the idea of lifetime appointments seemed the best way to establish an independent judiciary, insulating judges from the political forces that might endanger constitutional rights and liberties. But many now believe that the pendulum swung too far the other way, with a high court too reflective of past political fights and thus unresponsive to contemporary realities. Even if these critics are wrong, if public perception is that the justices are out‐of‐touch ideologues, that isn’t good for the Supreme Court as an institution or the American body politic more broadly. But if term limits were instituted, they would represent significant bipartisan consensus, given the difficulty of ratifying a constitutional amendment. That sort of consensus alone would indicate the resolution of many of the problems that term limits are being asked to remedy.
Still, the reasons for the growing public interest are clear. First, the average length of tenure has increased as a result of rising life expectancies, increased prestige of the job, and a reduction in the difficulties associated with service. Second, life tenure enables justices to time their retirement for political purposes, which takes away from the idea that the Court is detached from the partisan gamesmanship of Congress and the presidency. Third, the longer justices serve, the less accountable they become to democratic sentiments and the more independent they’re perceived to be from the cultural zeitgeist that inevitably informs the public’s response to the Court’s rulings. Finally, as Calabresi and Lindgren put it, “the irregular occurrence of vacancies on the Supreme Court means that when one does arise, the stakes are enormous,” and the brutal and often‐drawn‐out political combat that results affects the Court “directly, since it is deprived of one of its nine members, and indirectly, since rancorous confirmation battles lower the prestige of the Court.”
Calabresi and Lindgren argued that their proposal would address these and other concerns. First, 18‐year terms would reduce the post‐1970 average tenure of more than 25 years. Second, if presidents continued to appoint justices in their mid‐50s, ages at retirement would drop, thus lowering the risk of mental or physical decrepitude. Third, the proposal would solve the problem of “hot spots”: Irregular vacancies are often clustered. Since Sandra Day O’Connor was confirmed in 1981, each of the past six presidents has been limited to two appointment opportunities in consecutive years. If vacancies were set to occur once every two years, every president would be able to pick two justices each term, which would, as Calabresi and Lindgren put it, “reduce the stakes of the nomination process and eliminate the uncertainty that now exists regarding when vacancies will occur,” making the Court “more democratically accountable and legitimate by providing for regular updating of the Court’s membership.” In other words, there would be a more direct connection between the will of the people and the direction of the Court.
But there are real risks, and ways in which instituting staggered term limits could spectacularly backfire. Imagine a scenario in which a GOP‐controlled Senate blocks a Democratic president’s 2025 and 2027 nominations. A Republican president is then elected in 2028 and the Senate confirms four nominees: in 2029 and 2031, to serve the regular 18‐year terms, and for the two empty seats, with 14 and 16 years left on their terms, respectively. This could happen in every cycle of divided government, and would exacerbate, not lessen, the politicization of the confirmation process.
What’s more, if these 18‐year terms had been around for the past few decades, the Court’s makeup would hardly be different; there would now be three George W. Bush appointees, four Barack Obama appointees, and two Donald Trump appointees. In the past 50 years, there have been 30 years of Republican presidents and 20 years of Democratic ones; if anything, liberal voices have been overrepresented on the Court. In other words, term limits wouldn’t change the ideological composition of the Court over time. Nor, for that matter, would they address the fundamental power that each justice wields, which is the reason we see such ferocious political battles every time a vacancy occurs.
There are also transition problems. Since term limits wouldn’t apply to sitting justices, for decades we would have term‐limited justices serving alongside life‐tenured ones. Moreover, it would take decades to get each seat’s 18‐year term aligned with the others. Future vacancies wouldn’t arise in an orderly manner, so some transitional justice could serve five or 10 years before another one arrives. At a certain point, someone could end up “limited” to 20, 25, or even 35 years. Fixes could be put in place to prevent all this, but at some point the complications become more trouble than they’re worth.
Could the Court weather accusations of illegitimacy and special‐interest capture in these novel circumstances? And, as some commentators have indicated, 18 years is still a long time—more than the pre‐1970 average tenure—so even with a biennial vacancy, the stakes would remain high, especially for those confirmation fights in which the Court’s balance is at stake.
Even if term limits wouldn’t change the Court’s decision making, they might be worth trying anyway, because at least there would be less randomness about when vacancies arise. As the UC Berkeley law professor Orin Kerr put it, “If the Supreme Court is going to have an ideological direction—which, for better or worse, history suggests it will—it is better to have that direction hinge on a more democratically accountable basis than the health of one or two octogenarians.”
The best argument for term limits is that they would make the Supreme Court more of a standard issue in presidential and Senate campaigns and thus less of a political football when the winners of those elections get to nominate and confirm justices.
