The measure needed a two-thirds majority to pass. It fell far short. The vote breakdown revealed the deep partisan divide over the future composition of America’s highest court, an institution that has remained at nine justices since 1869 — though nothing in the Constitution itself mandates that specific number.

Arizona GOP Rep. Andy Biggs proposed the amendment, which would have amended the Constitution to read: “The Supreme Court of the United States shall be composed of nine justices consisting of one chief justice and eight associate justices.” The proposed language represented an attempt to codify what has been a long-standing tradition into the nation’s foundational legal document, making any future changes to the court’s size far more difficult to achieve.

“THE SUPREME COURT OF THE UNITED STATES SHALL BE COMPOSED OF NINE JUSTICES CONSISTING OF ONE CHIEF JUSTICE AND EIGHT ASSOCIATE JUSTICES.”

The vote comes as calls to expand the Supreme Court have intensified in recent years — driven largely by Republicans’ success in confirming conservative justices who have ruled on landmark cases favoring the right. The current 6-3 conservative majority has reshaped American jurisprudence on issues ranging from abortion rights to administrative law, fueling progressive frustration and renewed interest in structural reforms to the federal judiciary.

The debate over court composition is not new to American politics. Congress has changed the number of Supreme Court justices seven times throughout history, with the count fluctuating from as few as five to as many as ten before settling at nine in the aftermath of the Civil War. The most famous attempt to alter the court’s size came in 1937, when President Franklin D. Roosevelt proposed expanding it to as many as fifteen justices after the court struck down key New Deal legislation. That effort failed amid bipartisan opposition and remains a cautionary tale about perceived threats to judicial independence.

Massachusetts House Democratic Whip Katherine Clark’s office urged fellow Democrats to vote no, arguing the amendment would strip Congress of a constitutional authority meant to be controlled by the people’s representatives. This position reflects the Democratic argument that flexibility in court size serves as a legitimate constitutional check on an unelected judiciary.

“This proposed constitutional amendment would permanently fix the number of Supreme Court justices at nine, stripping Congress of yet another constitutional authority that is meant to be controlled by the American people’s representatives,” Clark’s office wrote to lawmakers ahead of the vote.

Clark’s team also argued the measure does nothing to address what they called the “affordability crisis” under President Donald Trump — an angle that reveals Democrats’ real priority: keeping the court-packing option alive. By pivoting to economic concerns in their messaging, Democrats attempted to frame the Republican proposal as a distraction from kitchen-table issues, even as the underlying dispute centered squarely on institutional power and judicial philosophy.

The failed vote follows Tuesday’s House passage of a resolution condemning socialism, which saw eight centrist Democrats cross the aisle to support the measure. The back-to-back votes illustrate Republicans’ strategy of forcing Democrats to take positions on issues designed to expose internal party divisions and create potentially damaging campaign messaging ahead of future election cycles.

Republicans have framed the amendment as a safeguard against partisan manipulation of the judiciary. Democrats’ unified opposition signals they’re unwilling to close the door on expanding the court if they regain power — a move conservatives have warned would destroy judicial independence. The party-line nature of the vote underscores how even structural questions about governmental institutions have become polarized along partisan lines, with little common ground remaining on issues that previous generations might have addressed through bipartisan consensus.

With the GOP now controlling the House, the amendment’s failure underscores the uphill battle Republicans face in locking in structural protections against future Democrat overreach. Constitutional amendments require not only two-thirds support in both chambers of Congress but also ratification by three-quarters of state legislatures, making them extraordinarily difficult to achieve even under favorable political conditions. Wednesday’s vote demonstrated that Republicans lack even the first hurdle of supermajority support needed to advance such proposals.

If a sitting majority can change the size of the Supreme Court the moment it dislikes its rulings, what happens the next time the other side is in power?

The resolution, if approved by two-thirds of both chambers, would be sent to the states as a constitutional amendment fixing the number of justices at nine.

Democrats proposed expanding the court to 13 justices in 2021 and again in 2023. With potential Democratic majorities looming in January, the threat to judicial independence has never been more urgent.

“It is a measure which should be so emphatically rejected that its parallel will never again be presented to the free representatives of the free people of America.”

Those words came from a Democrat-controlled Senate Judiciary Committee in 1937 — stopping FDR’s court-packing scheme before it reached the House floor. Roosevelt wanted to add as many as six justices to push through his New Deal programs. Even his own party called it a power grab.

For over 150 years, Congress has not altered the number of justices on the court. That stability preserved the court’s independence as an institution that renders decisions based on law, not politics.

But the left sees the court as an obstacle. When rulings don’t go their way, they threaten to change the referee instead of the rules.

The first round of court-packing would set off a cycle of retaliation. Each new congressional majority would add justices to offset those added by its predecessor. With every expansion, the court’s ability to check government excess would disappear.

History proves the danger. In 2004, Venezuelan President Hugo Chavez expanded that country’s Supreme Tribunal from 20 to 32 members. The court became a tool for consolidating power and marginalizing opposition. The rule of law collapsed.

Alexander Hamilton called the judiciary the “least dangerous” branch — exercising “neither force nor will but merely judgment.” That role as a final check against government abuse will not be regained once lost.

Congress must pass the proposed amendment and send it to the states for ratification.

In a strategic move, the House Judiciary Committee is set to consider a constitutional amendment known as the “Keep Nine” amendment this Wednesday. The proposal aims to cement the number of justices on the U.S. Supreme Court at nine, a number that has stood since 1869. This comes amid renewed attempts by some Democrats to expand the court following the Supreme Court’s recent decision in Louisiana v. Callais.

The Keep Nine Coalition, a bipartisan group, has been advocating for this amendment to safeguard the court’s independence. “We’ve survived for [nearly] 250 years with a court that has been able to say no to politicians when it really had to,” Roman Buhler, the coalition’s director, emphasized.

“WE’VE SURVIVED FOR [NEARLY] 250 YEARS WITH A COURT THAT HAS BEEN ABLE TO SAY NO TO POLITICIANS WHEN IT REALLY HAD TO,” ROMAN BUHLER SAID.

The Keep Nine Coalition’s origins trace back to 2017-2018 amid rising dissatisfaction on the left with the court’s direction. The coalition seeks to thwart any Democrat strategy to eliminate the Senate filibuster and pack the Supreme Court. The late Andrew Miller, former Virginia Attorney General, was among the early Democrat supporters, along with a coalition of state attorneys general.

Efforts to introduce the amendment in Congress were initiated by then-Rep. Collin Peterson, D-Minn., and supported by Sen. Ted Cruz, R-Texas. “The Supreme Court is an important part of our country’s system of checks and balances, and it is vital that we preserve its independence,” Peterson stated.

“THE SUPREME COURT IS AN IMPORTANT PART OF OUR COUNTRY’S SYSTEM OF CHECKS AND BALANCES, AND IT IS VITAL THAT WE PRESERVE ITS INDEPENDENCE,” PETERSON SAID.

Currently, the coalition boasts nearly 130 co-sponsors in Congress thanks to grassroots efforts from organizations like the National Federation of Republican Women. Despite this momentum, Buhler acknowledges the difficulty in securing bipartisan support, with no current Democrat co-sponsors.

Buhler cites conversations with several Democrat lawmakers who privately oppose court-packing but face party pressure. “The challenge for us is to get those members who agree that court expansion is a bad idea to go to the next step,” Buhler remarked.

Looking ahead, the coalition aims to break this impasse by encouraging a handful of Democrats to publicly oppose court expansion. This stance could potentially shift strategic calculations within the party, making the Keep Nine amendment a significant factor in future legislative discussions.
