What Happens in the Supreme Court's Conference Room After Oral Argument

Imagine the most important meeting in American government. No staff, no stenographer, no cameras, no press secretary, no lobbyist waiting in the hall. The room is locked, and the youngest member by service is the one who gets up to answer if somebody knocks. It sounds like a club for retired schoolteachers. It is, in fact, where the supreme law of the land gets its final shape.

Let us walk through it, because the way the Court decides is part of the constitutional design, and because most of what Americans think they know about that process comes from movies and from partial leaks. The truth is plainer and more interesting. The deliberations are private by tradition, the conference is the fulcrum, and the real work happens afterward, on paper.

The setting: the term and the argument

The Court's term opens on the first Monday in October, as federal law provides. Arguments are heard in sessions through the spring, with the justices sitting for two-week periods separated by recesses. Each side in a case usually gets thirty minutes of oral argument, though the Court sometimes allots more for a major dispute. The lawyer for the petitioner opens, the respondent follows, and the petitioner may reserve a few minutes for rebuttal. For a practical guide to listening, see How to Follow a Supreme Court Oral Argument, From the Line to the Transcript.

Argument matters, but it is not the decision. Everyone involved knows that by the time a lawyer rises, the justices have read the briefs, and many have already formed a tentative view. Argument is the chance to test it. A question from the bench can reveal a worry, a bridge to a different rule or a point on which the lawyer's whole case depends.

And then the justices leave the courtroom and go to the room that decides.

The conference

After the argument sessions, the justices meet in a private conference to discuss and vote. These conferences are held on set days during the term, usually within days of the arguments being heard, and they are attended only by the nine justices. No law clerks, no court staff, no stenographers. The tradition is longstanding and the Court guards it fiercely.

Here are the main features of how it works.

Seniority governs. The Chief Justice speaks first, setting out his view of the case. Then each associate justice speaks in order of seniority, meaning by length of service on the Court, from the longest-serving to the newest. After discussion, they vote in the same order.

The most junior justice keeps the door. If someone knocks, perhaps with a note or a message, the junior justice answers it and handles the errand. That arrangement is a small ritual, and part of the point is practical: with no staff allowed in, someone has to be the one who opens the door. The newest justice also keeps a tally of the votes.

The Chief has the first word. Because the Chief Justice speaks first, he can frame the case, signal where he leans and set a tone for the rest. That is real influence, but it is influence only of a particular kind. The Chief casts one vote, the same as everyone else.

The conference runs on mutual respect, and by most accounts it is far more civil and brief than outsiders expect. Justices have described the sessions in public remarks as collegial. There are no filibusters in the room, which makes it the only legislative-adjacent body in Washington where nobody has ever tried to talk a matter to death for sport. Each justice speaks, and the vote comes.

A strong word of caution is in order here. We know the general shape of the conference from the justices' own public descriptions and from long tradition. We do not have transcripts, because there are none. Anyone who claims to give you a blow-by-blow account of a particular recent conference is repeating a rumor, and you should treat it as one.

Why the private conference is defensible

Many Americans bristle at the secrecy. Congress debates in public, the presidency is endlessly covered, and here nine officials with lifetime tenure decide the meaning of the Constitution behind closed doors. That deserves a fair answer.

The case for privacy has three parts.

One. Candor. A justice who knows his words will be read aloud on the evening news will speak less freely. The conference is where a justice can say "I think I was wrong in the last case," or "I am not sure how I come out on this," without fearing that his hesitation becomes a talking point.

Two. Persuasion. Votes can change in the conference and after it, and a justice who changes his mind faces less embarrassment if the process is private.

Three. The public record is the opinion. The Constitution does not require the Court to deliberate in public. It requires the Court to decide cases and give reasons. The reasons come out in written opinions that everyone can read, criticize and cite. The Founders were not trying to televise the deliberations of the Constitutional Convention itself; the delegates met in secret in Philadelphia in the summer of 1787, behind closed doors, so that they could speak freely. The tradition of closed deliberation has a distinguished start.

That said, the privacy is a convention, not a command, and public confidence in the Court depends on the opinions being honest. In May 2022 the unauthorized publication of a draft opinion in the Dobbs case was a break with a tradition that had held for generations. The Court confirmed the draft was authentic, and the Chief Justice ordered an investigation. The final opinion was issued on June 24, 2022. The episode showed how much the tradition of confidentiality means, and how much damage can follow from its breach.

Assigning the opinion

Once the votes are counted, someone must write the majority opinion. The rule is simple and has large consequences.

• If the Chief Justice is in the majority, he assigns the opinion. He may keep it for himself or give it to a colleague.
• If the Chief Justice is in the minority, the senior justice in the majority assigns it. The most senior associate among those who voted with the majority makes the choice.

This is real power. The author of the majority opinion shapes the reasoning, the breadth of the holding and often the tone. A narrow opinion and a sweeping one can lead to the same judgment while setting very different precedents. A Chief Justice who wants to hold a coalition together may give the assignment to the justice whose views are closest to the middle, or to the most skeptical member of the majority, so that the opinion will be written in a way all five can sign.

Chief Justice Earl Warren gave a famous example. In Brown v. Board of Education (1954), after the Court had struggled with the case and then reargued it following the death of Chief Justice Vinson, Warren took the opinion for himself and wrote it in plain language, aiming for a unanimous Court. The opinion was meant to be readable by the public. Whatever one thinks of the reasoning, the assignment decision was a deliberate choice about how a precedent would sound.

Notice, too, that this is a power the Chief Justice has by custom and by the logic of his office, not by a constitutional clause. The text of the Constitution mentions the Chief Justice once, in connection with presiding at a presidential impeachment trial. Everything else about his role comes from practice.

Circulated drafts, and how votes shift

The vote in conference is provisional. It is a first count, not a final judgment. Once an opinion is assigned, the author writes a draft and circulates it to the other justices, who respond in writing. A justice may join the opinion, suggest changes, ask for a particular sentence to be deleted, or announce that he will write separately.

Several things can happen.

1. The majority holds. The draft is revised in response to comments and the opinion goes out.
2. The majority wobbles. A justice who voted with the majority reads the draft and decides the reasoning goes too far, or not far enough. If one vote moves, a five-justice majority becomes four, and the case may flip. The author can try to repair the opinion to win back the vote.
3. The dissent persuades. A well-written dissent can change minds. Dissents, as Five Supreme Court Dissents That Later Became the Law of the Land shows, are sometimes appeals to the future, and sometimes they win in the present.

Because opinions are circulated and revised, the real decision of the Court is not fixed at the moment of the vote. It becomes fixed when the last justice signs on. That is why a case argued in October may not come down until June.

Concurrences and dissents

The Court speaks in several voices, and each has a name.

• The opinion of the Court is the majority opinion, which binds as precedent.
• A concurrence is written by a justice who agrees with the result but not with the reasoning, or who wants to add a point. A concurrence can be quietly important. When a plurality falls short of a majority, the narrowest concurrence may control.
• A dissent is written by a justice who disagrees with the result.
• A concurrence in part and dissent in part is just what it sounds like.

It is easy to forget that this practice was a choice. For most of the Court's early years, under Chief Justice John Marshall, the Court moved away from the English habit of each judge delivering his own opinion in turn, called seriatim opinions, toward a single opinion of the Court. Marshall's habit of speaking for a unified Court helped establish the institution's authority. Thomas Jefferson disliked it and preferred that the justices write separately. The modern Court has swung back toward multiple writings, and many cases today produce several opinions.

Whether this is a good thing is an open question among conservatives. A single clear opinion gives lower courts and citizens a rule they can follow. A fractured set of opinions can leave the law in doubt. On the other hand, a dissent preserves an alternative that might someday be vindicated, and it keeps the majority honest.

June, and the release of opinions

The opinions of the Court are released through the spring and, for the hardest cases, in the last weeks of the term, which usually ends in late June and occasionally runs into the first days of July. In 2024, for example, the decision in Trump v. United States came down on July 1.

Opinions are announced from the bench on scheduled days, with the justices sitting in public. Tradition has the author of the majority opinion summarize it from the bench. In significant cases, a justice who dissents may read a summary of his or her dissent aloud, a gesture reserved for strong disagreement. The opinions are then posted on the Court's website, where anyone can read them. That is the moment the public process begins.

The strongest objection, answered

A critic says: "This is an unaccountable group of nine people who meet behind closed doors and decide the fate of the nation, with life tenure and no review. It looks less like a court than a council of guardians."

It is an objection worth taking seriously, and the answer has several parts.

One. The Court's reasoning is public. What the justices decide, they must explain in writing, and the reasons can be examined and attacked. A guardian does not publish a brief.

Two. The Court has no army and no budget. Hamilton described this in Federalist 78: the judiciary holds neither the sword nor the purse and has "neither force nor will, but merely judgment." Its decisions work only because others carry them out.

Three. The political branches control who sits and how many. The President nominates the justices and the Senate confirms them. Congress sets the size of the Court and the scope of its jurisdiction. The nine have sat since 1869, and Nine Justices Since 1869, and Why the Number Should Stay Nine makes the case that they should keep sitting.

Four. The remedy for a bad decision is available. Amend the Constitution, pass a law where the decision turned on a statute, or wait for the Court to reconsider, as it has done many times. From Plessy to Chevron, a Timeline of Precedents the Court Was Right to Overrule gives a timeline.

None of this makes the conference unimportant. It makes it part of a system in which every move by the justices can be answered by someone else.

What this means for conservatives

Understanding the process gives conservatives three habits worth cultivating. Read the opinion itself, not the headline, because the reasoning, not the result, is what binds the future. Pay attention to concurrences, since they often reveal how much agreement exists behind a holding. And remember that the justices are nine human beings who do their work by arguing and writing, and who can be persuaded by a sound argument grounded in text and history. That is why the briefs and the argument matter.

It is also a reminder of why Four Votes to Hear a Case, Five to Win It, Inside the Supreme Court's Docket matters: the Court controls its own agenda, and the conference is where it exercises that control. And it explains why the press coverage of a decision deserves skepticism, since many reporters write about the result and the politics of the justices but not about the opinions; How the Press Covers Supreme Court Decisions, and What the Stories Leave Out covers that.

The case in brief

1. The justices meet alone in conference after argument, speak in order of seniority and vote in the same order, with the junior justice keeping the door and no staff present.
2. The Chief Justice assigns the majority opinion when he is in the majority, and the senior justice in the majority assigns it when he is not, a custom that shapes how broad a precedent becomes.
3. The vote in conference is provisional, and circulated drafts, concurrences and dissents can shift the outcome before a case is released.
4. Privacy protects candor, and the public record is the written opinion, which the Court must publish and defend.
5. The Court's power is checked by nomination, confirmation, jurisdiction, amendment and its own reconsideration.

What you can do: pick one decision from the most recent term, read the first ten pages of the majority opinion and the first five of the dissent on the Court's website, and note where they disagree.
