A large share of consequential American legal decisions now arrive through a process most people have never heard of: the Supreme Court’s emergency docket, sometimes called the shadow docket by its critics.

The mail ballot case we report on separately today is one of these. Here is what the process is, how it differs from a normal case, and what the argument about it actually concerns.

How a normal case works

The Supreme Court’s ordinary process is slow by design. A case is tried, appealed to a circuit court, and then a party asks the Supreme Court to hear it. If four justices agree, the court takes it. Both sides file extensive written briefs, outside organisations file their own, oral argument is held and recorded, and months later a signed opinion issues, setting out the reasoning and any dissents.

That opinion is precedent. Lower courts must follow it, lawyers can read the reasoning, and the public can see which justice thought what and why.

How an emergency application works

An emergency application asks the court to do something now, while a case is still being litigated — typically to stay a lower court’s ruling, or to lift a stay someone else obtained.

The differences are substantial. Timetables are measured in days, as with the ten o’clock deadline set in the mail ballot case. Briefing is short. There is usually no oral argument. Orders are often brief and sometimes unsigned, so the reasoning may not be stated and the vote may not be recorded. Individual justices handle applications from assigned circuits and may refer them to the full court.

Formally, the court is not deciding who wins. It is deciding what happens in the meantime, using a test that weighs likelihood of success, irreparable harm and the public interest.

Why “in the meantime” often means “in the end”

This is the crux of the criticism, and it is a practical point rather than an ideological one.

For many disputes, the interim period is the whole period. An election happens on a fixed date. A deportation, once carried out, is not undone by a later ruling. A policy operating for a year has effects that a subsequent judgment cannot reverse. In such cases whoever wins the emergency application has in practice won, whatever the merits decision says afterwards — or whether one ever comes.

Critics — including legal academics who coined the shadow docket label and justices who have written dissents from these orders — make three objections. Decisions of real consequence are made without full argument. Unsigned orders without reasoning give lower courts little guidance while still functioning as instructions. And the absence of recorded votes reduces accountability.

The defence

The response, made by other justices and by scholars who think the criticism overstated, has several parts.

Emergency jurisdiction is not new; the court has always had a mechanism for urgent applications, and it exists because some disputes genuinely cannot wait for a full term. The growth in applications reflects a growth in nationwide injunctions issued by district judges against federal policy, which forces the government to seek emergency relief — a change in the behaviour of lower courts as much as of the Supreme Court. And a stay is genuinely not a ruling on the merits: treating it as one misdescribes what the court has done.

There is a reasonable middle position, and several justices across the court’s divisions have gestured at it: that the emergency docket is legitimate and necessary, but that orders with major practical consequences should come with brief published reasoning, so that lower courts and the public can see the basis. That is a criticism of practice rather than of jurisdiction.

How to read the coverage

Three things are worth holding when an emergency order appears in the news.

First, an order granting or denying a stay is not a ruling that the policy is lawful or unlawful, and headlines describing it that way are wrong on the law even when they capture the practical effect.

Second, if there is no opinion, nobody outside the court knows the reasoning — including the lawyers who must now advise clients. Confident explanations of why the court acted are inference.

Third, the practical effect may nonetheless be permanent, and saying so is not cynicism. It is the reason the argument about this process is worth having at all.
