Republicans pushed a constitutional amendment to permanently cap the Supreme Court at nine seats, but Democrats voted it down, refusing to close the door on expanding the bench if they retake power.

The House voted Wednesday afternoon on Rep. Andy Biggs's proposed amendment, which would have written the current nine-justice structure into the Constitution. A majority of lawmakers backed it. That was not enough. Speaker Mike Johnson had fast-tracked the measure using a procedural shortcut called "suspension of the rules," which skips committee markups and floor amendments but raises the passage bar from a simple majority to two-thirds. Democrats voted against it almost unanimously, and the amendment fell short of that threshold, Fox News Digital reported.

The result leaves the size of the Supreme Court exactly where it has been since 1869, set by ordinary statute, changeable by any future Congress with the votes to do it. And that is precisely the vulnerability Republicans wanted to eliminate.

Biggs warned the bench would become "another political institution"

The Arizona Republican framed the vote as a test of whether Congress would protect the judiciary's independence or leave it exposed to partisan manipulation. On the House floor Wednesday, Biggs laid out the stakes in plain terms.

"Here's the question every American should ask: If a sitting majority can change the size of the Supreme Court the moment it dislikes rulings, what happens to the next time the other side is in power?"

He pressed the point further:

"Once you go down that road, the court stops being an independent check on government power. It becomes another political institution controlled by whoever happens to hold the majority."

Rep. Mark Harris, a North Carolina Republican, backed the amendment with a similar argument. Harris pointed to what he called an "alarming rise" in calls to expand the bench.

"For decades, we have heard calls from those unhappy with the ideological balance of the Supreme Court to pack the court. The alarming rise of such calls should worry all of us, because their objective is not to uphold ethical principles or even to protect individual rights, but rather to consolidate power and intimidate the court."

That argument did not move Democrats.

Raskin called the amendment a "partisan power grab", then made the case for 13 justices

Rep. Jamie Raskin, the Maryland Democrat, led the opposition on the floor. He accused Republicans of trying to freeze a court that he described as tilted in their favor. Raskin is among progressives who want to expand the bench to 13 justices, one for each federal circuit court of appeals.

"MAGA's proposal is to strip Congress of all authority in the matter, to freeze it and cement it permanently in the constitutional architecture for all time with the suddenly magic number nine."

Raskin went further, tying the amendment to broader grievances about the current administration's record:

"It's another partisan power grab by MAGA, our colleagues, who fear for the results of the November election as their policies have brought us nothing but war, inflation, corruption, lawlessness and a $40 trillion debt, one quarter of it's supplied by this presidential administration. So, the MAGA party wants to cement into place a profoundly partisan and lopsided... court that was gerrymandered and engineered by Mitch McConnell."

Rep. Mary Gay Scanlon, a Pennsylvania Democrat, echoed Raskin's objection but framed it differently. She argued that locking the number at nine would entrench a conservative majority for a generation.

"I think it would be a grave mistake to dictate how many justices should sit on the Supreme Court in perpetuity, and thereby lock in for a generation or more a right-wing majority, which is engaged in an unprecedented assault on Supreme Court norms and our constitutional order for the past several years."

Read those two arguments side by side and the Democratic position becomes clear: the objection is not about constitutional principle. It is about keeping the option to add seats when the political math changes.

Johnson's procedural gamble raised the bar Republicans couldn't clear

Speaker Johnson's decision to use the suspension procedure deserves scrutiny. The shortcut let him bypass the slower committee process and bring the amendment directly to a floor vote. But it came with a cost. Under suspension of the rules, passage requires a two-thirds supermajority instead of a simple majority. In a closely divided House, that meant Johnson needed a significant number of Democrats to cross the aisle.

Almost none did.

The exact vote tally, how many Democrats, if any, voted yes, and whether any Republicans voted no, was not reported. But the outcome was unambiguous: the amendment failed. A majority supported it, yet the two-thirds threshold turned that majority into a defeat.

Constitutional amendments face an even steeper climb beyond the House. They require two-thirds approval in both chambers and ratification by three-fourths of state legislatures. Wednesday's vote did not even clear the first hurdle.

Democrats have openly endorsed court expansion for years

The amendment was not drafted in a vacuum. President Trump has warned for months that Democrats would seek to expand the Supreme Court if they regained control of Congress. Top progressives have confirmed as much. Former Vice President Kamala Harris and Sen. Elizabeth Warren of Massachusetts are among those who have publicly affirmed support for adding seats to the bench.

The Constitution does not specify a number of justices. Congress has changed the court's size multiple times throughout American history. That flexibility is exactly what Biggs's amendment aimed to eliminate, and exactly what Democrats voted to preserve.

Raskin's floor argument made the progressive case explicit: the current nine-seat court is, in his telling, illegitimate because of the role former Senate GOP Leader Mitch McConnell played in shaping its conservative majority. If the court's composition is the product of political maneuvering, Raskin's logic goes, then political maneuvering should be available to reshape it.

Republicans see that reasoning as a confirmation of their fears, not a rebuttal. Harris, the North Carolina congressman, called the push to expand the court an effort to "consolidate power and intimidate the court." Biggs warned that once one side adds seats, the cycle never ends, every future majority would feel entitled to do the same.

Nine justices survived the vote, but the guardrail didn't

The Supreme Court will remain at nine justices for now. Nothing about Wednesday's vote changes the current bench. But the amendment's failure means the structural protection Republicans sought does not exist. The number of justices remains a matter of ordinary legislation, vulnerable to any future Congress willing to change it.

Democrats did not argue that nine is the wrong number today. They argued against making nine permanent. Scanlon said it would be a "grave mistake" to set the number "in perpetuity." Raskin dismissed nine as a "suddenly magic number." Neither offered a principled reason why Congress should retain the power to resize the judiciary other than the desire to use it.

That is the tell. When one side refuses to lock the door, it is because they plan to walk through it.
