No. 20-437October Term 2020Decided Jun 1, 2021
United States v. Palomar-Santiago
The key question is whether a mistaken removal order alone lets a defendant bypass Congress's separate conditions for challenging that order.

- What it's about
This case asked whether a person charged with illegally returning to the United States can attack the validity of an earlier deportation order without meeting all of the statutory requirements for that kind of challenge. It arose after Palomar-Santiago argued that his original removal was invalid because the drunk-driving conviction used to deport him was later held not to be a removable aggravated felony.
Question presented
The question presented is whether a defendant automatically satisfies all three of those prerequisites solely by showing that he was removed for a crime that would not be considered a removable offense under current circuit law, even if he cannot independently demonstrate administrative exhaustion or deprivation of the opportunity for judicial review.

Briefing
What it's about
The justices are being asked whether a person charged with illegally returning to the United States can challenge an earlier deportation order without meeting all three steps Congress set out for that kind of attack. Palomar-Santiago says his original removal was invalid because it was based on a drunk-driving conviction that was later treated as not making him removable under Ninth Circuit law.
Vote
The Court has not scheduled oral argument yet. The dispute is whether showing the original removal was legally wrong by itself excuses the statute's other requirements, such as using available agency appeals and lacking a real chance for court review.
Impact
The answer could affect noncitizens facing illegal-reentry prosecutions who want to argue that their old deportation orders were legally flawed. For example, it could decide whether someone removed over a conviction later deemed non-removable still must show he used available agency appeals and lacked a real chance for court review.
What's next
Watch for the Supreme Court to schedule oral argument or make another calendar move. No decision window is available yet.
What exactly is the Supreme Court being asked to decide?
It must decide whether a defendant can attack an old deportation order by showing only that the order was legally mistaken. Or whether he also must meet the statute's other required steps.
Who could be affected if the Court sides with either view?
The case could affect noncitizens prosecuted for returning after removal. It may shape how often flawed old deportation orders can be challenged in those criminal cases.
What should court watchers look for next in this case?
The next major sign is oral argument being scheduled, unless the Court makes another scheduling move first. No decision timing is available yet.
