Reversed and remanded. Klopfer won.
What this ruling means
Reversed and remanded: the Supreme Court overturned the decision of the North Carolina Supreme Court and sent the case back to that court for further proceedings that follow the Supreme Court’s ruling.
Klopfer 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.
Klopfer v. North Carolina, 386 U.S. 213 (1967), was a decision by the United States Supreme Court involving the application of the Speedy Trial Clause of the United States Constitution in state court proceedings. The Sixth Amendment in the Bill of Rights states that in criminal prosecutions "...the accused shall enjoy the right to a speedy trial" In this case, a defendant was tried for trespassing and the initial jury could not reach a verdict. The prosecutor neither dismissed nor reinstated the case but used an unusual procedure to leave it open, potentially indefinitely. Klopfer argued that this denied him his right to a speedy trial. In deciding in his favor, the Supreme Court incorporated the speedy trial protections of the Sixth Amendment against the states.

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
- Sixth Amendment (speedy trial)
- Kind of law
- Constitutional Amendment
- Decided by
- Judicial review (state level)
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.
