Reversed and remanded. Ignacio Carlos Flores-Figueroa won.
What this ruling means
Reversed and remanded: the Supreme Court overturned the decision of the U.S. Court of Appeals, Eighth Circuit and sent the case back to that court for further proceedings that follow the Supreme Court’s ruling.
Ignacio Carlos Flores-Figueroa was the petitioner, the side that asked the Supreme Court to review the case. “Won” means the Court gave that side the result it asked for.
From the Supreme Court Database. A justice who agreed with the result but not the reasoning counts in the majority.
Summary
The opening of the case’s Wikipedia article: what the case was about and what the Court held.
Flores-Figueroa v. United States, 556 U.S. 646 (2009), was a decision by the Supreme Court of the United States, holding that the law enhancing the sentence for identity theft requires proof that an individual knew that the identity card or number he had used belonged to another, actual person. Simply using a Social Security Number is not sufficient connection to another individual.

Data notes
Each justice’s vote and what they wrote are from the justice-centered file of the Supreme Court Database. “Wrote a concurrence” means the justice sided with the majority and wrote separately; a justice who dissented in part is counted on the side they took overall. A justice who wrote nothing is listed as joining their side.
Positions are each justice’s Martin–Quinn score for the case’s term, the same scores as the Ideology page: negative is more liberal, positive more conservative. A score sums up a justice’s votes across the whole term, so it says where they usually sit, not why they voted as they did here. The median line is the Court’s median justice that term.

Data notes
The names are the two sides of the case’s title. The description under each is the Supreme Court Database’s category for that party, in its own wording. The petitioner is the side that asked the Supreme Court to review the decision below. “Why it was taken” appears only when the majority opinion says lower courts disagreed or were unsure about the question; reasons that would fit any case (“to resolve the question presented”, “an important question”) are left out.
The law at issue
The law the Court was asked to apply, and the kind of power it used to decide.
- Provision
- 18-1028
- Kind of law
- Infrequently litigated statutes
- Decided by
- Statutory construction
Data notes
The Supreme Court Database codes the main constitutional provision, statute or court rule each case turned on, and the basis of the decision: judicial review of a federal or state law, interpreting a statute, supervising the lower courts, and so on. A case can rest on more than one. “Overruled” counts only where the majority opinion says so.
