The battle over the size of the U.S. Supreme Court has reignited with unprecedented intensity, as a coalition of progressive groups and Democratic lawmakers pushes for legislation to add four new seats to the nine-justice bench. Chants of “Let’s pack it now” have echoed at rallies outside the Capitol, while Republican leaders denounce the effort as an assault on the rule of law. The confrontation, unfolding just weeks before the midterm elections, threatens to reshape the judiciary and deepen the institutional crisis that has gripped Washington.
**Context**
The Supreme Court has consisted of nine justices since 1869, a number set by Congress during the presidency of Ulysses S. Grant. Attempts to alter that figure have historically been rare and politically explosive. President Franklin D. Roosevelt’s 1937 “court-packing” plan, which sought to add up to six justices to secure New Deal legislation, failed after a bipartisan backlash. Since then, the nine-justice norm has been treated as sacrosanct, even as the Court’s ideological balance has swung dramatically.
The current push for expansion stems from a series of Republican procedural maneuvers that Democrats view as illegitimate. In 2016, Senate Majority Leader Mitch McConnell refused to hold hearings for President Barack Obama’s nominee, Merrick Garland, arguing that the vacancy should be filled after the election. Four years later, McConnell rushed the confirmation of Amy Coney Barrett just days before the 2020 presidential election, cementing a 6–3 conservative majority. That majority has since delivered landmark rulings, including the 2022 overturning of Roe v. Wade, the expansion of gun rights, and the curtailment of federal regulatory power.
In response, President Joe Biden in 2021 established a bipartisan commission to study Supreme Court reform. The commission’s final report, released in December 2021, outlined arguments for and against expansion but did not endorse any specific proposal. Biden himself has remained publicly neutral on court packing, though he has expressed openness to other reforms such as term limits for justices and a binding code of ethics. Meanwhile, progressive lawmakers, led by Senator Ed Markey and Representative Jerry Nadler, have introduced the Judiciary Act of 2023, which would increase the Court to 13 justices. The bill has stalled in committee but has become a rallying cry for activist groups.
**Analysis**
The renewed clash over court expansion is not merely a procedural dispute; it reflects a fundamental disagreement about the nature of judicial legitimacy. Proponents argue that the current conservative majority was obtained through what they call “stolen seats”—the Garland blockade and the Barrett confirmation—and that restoring balance is necessary to protect civil rights, environmental protections, and voting access. They point to public opinion polls showing that a majority of Americans believe the Court is too political and that structural reform is overdue. The slogan “Let’s pack it now” has become a digital-age echo of Roosevelt’s failed effort, but with a key difference: today’s activists are not seeking to save a legislative agenda but to counter what they see as a partisan takeover of the judiciary.
Opponents, including Senate Minority Leader McConnell and former Attorney General William Barr, warn that expansion would destroy the Court’s independence and turn it into a political football. They argue that if Democrats add seats when they control the White House and Congress, Republicans will do the same when they regain power, leading to an endless cycle of expansion. The result, they say, would be a Court that mirrors the partisan composition of the legislature, undermining its role as a neutral arbiter of constitutional questions. Some legal scholars, such as Harvard’s Noah Feldman, have proposed alternative reforms like staggered 18-year terms, but these have gained little traction in Congress.
The political calculus is complex. Even if Democrats were to win unified control of the government in the upcoming elections, the filibuster in the Senate would likely block any expansion bill. Moderate Democrats, including Senators Joe Manchin and Kyrsten Sinema, have voiced opposition to court packing. Yet the issue has become a litmus test for progressive primary challengers, and the pressure on Democratic leaders is mounting. The clash is also playing out in state legislatures, where some Republican-controlled states have passed resolutions opposing expansion and calling for a constitutional convention to limit the Court’s size.
