In plain English
When a judge must justify your jailing.

Habeas corpus lets anyone the government locks up demand that a judge decide whether the detention is lawful.

Simple example
In Boumediene v. Bush (2008), the Supreme Court held that Guantanamo detainees could challenge their detention through habeas petitions.
Why it matters
What the term actually changes.
Bedrock liberty

Habeas is the oldest safeguard against arbitrary imprisonment, predating the Constitution itself.

Crisis pressure

The Constitution allows suspension only in rebellion or invasion — a line tested during the Civil War and the war on terror.

How it works
The mechanics, in practice.
The petition

A detainee (or someone acting for them) files a habeas petition asking a court to review the detention.

The review

The government must justify the imprisonment; if it can't, the court orders release or a new proceeding.
