The voteMajorityDissent

6–36 in the majority, 3 in dissent

3 dissents (6–3)

Reversed and remanded. Washington, et al. won.

What this ruling means

Reversed and remanded: the Supreme Court overturned the decision of the Washington Supreme Court and sent the case back to that court for further proceedings that follow the Supreme Court’s ruling.

Washington, et al. 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.

How the justices voted

Each justice who took part, placed by their Martin–Quinn ideology score for the 1989 term. Filled: the 6 in the majority. Hollow: the 3 in dissent. Colour is the party of the president who appointed them.

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 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
Article III, Section 2, Paragraph 1 (case or controversy requirement)
Kind of law
Constitution
Decided by
Judicial review (national 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.
