Court Packing and the Separation of Powers

A sitting U.S. senator just addressed, in plain terms, a topic that can turn politically volatile fast. Senator Raphael Warnock of Georgia, asked on Meet the Press about expanding the Supreme Court, replied that all options have to be on the table.

That line matters because court expansion is not a trivia question. It is a separation-of-powers question. It is a legitimacy question. It is a question about whether we still want judges to be referees or whether we are ready to treat them as political prizes.

The basics

The Constitution does not lock in the number of Supreme Court justices. Article III creates “one supreme Court,” but it does not say whether that Court has five members, nine members, or nineteen.

So who decides the size? Congress, by statute. And the President, through nominations and signatures. That is not a loophole. That is how the system is built.

But there is a catch my students always missed on the first pass: just because something is legal does not mean it is healthy. Separation of powers is not only about who has the power on paper. It is also about whether each branch can do its job without constant threats of structural payback from the others.

What “court packing” means

Let us be precise. “Court packing” is not every change to the judiciary. It is a specific move: changing the number of seats on the Supreme Court to change outcomes, usually quickly, usually because the current Court is issuing decisions one political coalition cannot tolerate.

That is why Warnock’s phrasing lands with force. “All options” treats expansion as a live possibility rather than an academic debate.

Supporters call that democratic accountability. Critics call it intimidation with parliamentary tools. Either way, it is pressure aimed at the one branch designed to be least responsive to the political weather.

Legitimacy

Congress has electoral legitimacy. The President has electoral legitimacy. The Supreme Court runs on a different currency: legal legitimacy. It cannot order an army. It cannot levy a tax. It survives because the public and the political branches generally accept its decisions as binding even when they hurt.

Court packing risks changing that bargain. If the Court’s size becomes a routine partisan lever, decisions can start to look less like law and more like the latest scoreboard.

Once the Court looks like a scoreboard, two risks follow:

• Judicial independence shrinks because every major ruling invites threats of structural retaliation.
• Compliance becomes conditional because losing sides stop seeing rulings as authoritative and start seeing them as temporary.

Escalation

One part of the debate gets too little attention: the consequence is not what happens the first time. It is what happens the second time.

If one party expands the Court to secure a governing majority, the other party learns the lesson immediately: do not persuade, do not wait, just expand it again when power changes hands.

That turns the Supreme Court into a revolving door. Not because justices rotate, but because the institution becomes unstable. Stability is not a luxury feature in constitutional government. It is a core requirement.

Norms

In the textbook version, each branch checks the others so that ambition counters ambition. In the real version, the branches also develop norms. Those norms are often what prevent constitutional hardball from becoming constitutional demolition.

Court packing is risky because it can change the Supreme Court from a check on politics into an instrument of politics.

Ask the hard question: if Congress can effectively rewrite the Court whenever it dislikes a line of cases, what is the Court checking anymore? The legislative branch becomes both rule-maker and, indirectly, rule-interpreter. That is not separation of powers. That is consolidation.

The case for expansion

There is a serious, not-crazy argument that the Court’s current structure is straining under modern reality. The docket is limited. The judiciary beneath the Court has grown. A handful of justices can effectively settle nationwide disputes with enormous policy consequences, sometimes through emergency rulings that feel thinly explained to the public.

So reformers can argue that adding seats could dilute the power of any one justice, reduce the stakes of each nomination, or make the Court more representative of the country’s legal traditions.

But the separation-of-powers problem is motive and method. If expansion is framed as a way to change ideological outcomes right now, it teaches every future Congress that the Court is just another chamber waiting to be reconfigured.

How it works

If Congress tried to expand the Court, the steps would be straightforward:

• A bill would pass both houses setting a new number of justices.
• The President would sign it, or Congress would override a veto.
• The President would nominate new justices to fill the new seats.
• The Senate would confirm or reject those nominees.

The Court itself likely would not be able to stop it. The Constitution gives Congress broad authority to structure the federal judiciary. The barrier is political, not legal. That is exactly why the idea is so potent.

The real question

When Senator Warnock says all options have to be on the table, he is not only talking about one policy lever. The comment raises a choice that is easy to dodge until someone says it out loud: what kind of Court do we want?

Do we want a Supreme Court insulated enough to be unpopular and still function? Or do we want a Supreme Court responsive enough to stay aligned with electoral majorities, even if the institution’s rules change whenever power changes hands?

That is the heart of the matter. Court packing does not just alter the Court. It alters the relationship between law and politics, and it does it by shrinking the distance between the branch that makes the rules and the branch that is supposed to enforce limits.

A civics warning

In every era, politicians discover that the Constitution contains tools they can use. The harder test is whether they also have the restraint not to use every tool simply because they can.

Separation of powers is not self-executing. It is a habit. And habits, once broken, are hard to rebuild.
