What this ruling means
Affirmed: the Supreme Court upheld the decision of the U.S. Court of Appeals, Seventh Circuit, so it stands (sometimes with changes the Court made to it).
City of Indianapolis, et al. was the petitioner, the side that asked the Supreme Court to review the case. “Lost” means the Court did not give that side the result it asked for.

Summary
The opening of the case’s Wikipedia article: what the case was about and what the Court held.
City of Indianapolis v. Edmond, 531 U.S. 32 (2000), was a United States Supreme Court case in which the Court held, 6–3, that police may not conduct vehicle searches, specifically ones involving drug-sniffing police dogs, at a checkpoint or roadblock without reasonable suspicion. In the case, the Indianapolis Police Department was conducting warrantless searches of vehicles, without individualized suspicion, for the purpose of "general crime control". Previous Supreme Court decisions had given the police power to create roadblocks for the purposes of border security (United States v. Martinez-Fuerte) and removing drunk drivers from the road (Police v. Sitz), but in this decision, the Court limited police power, holding that the search can only occur if it was designed to serve special needs, beyond the normal need for law enforcement.

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.
The parties
Who brought the case to the Court, who answered it, and how it got there.
- Petitioner
- City of Indianapolis, et al.City, town, township, village, or borough government or governmental unit (Indiana)
- Respondent
- James Edmond et al.Private person
- Reached the Court by
- Certiorari (the Court chose to hear it)
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
- Fourth Amendment
- Kind of law
- Constitutional Amendment
- Decided by
- Judicial review (state level)
- Struck down
- A local ordinance, as unconstitutional
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.
