Decisions that do not note a Justice delivering the Court's opinion are per curiam. Multiple concurrences and dissents within a case are numbered, with joining votes numbered accordingly. Justices frequently join multiple opinions in a single case; each vote is subdivided accordingly. An asterisk ( * ) in the Court's opinion denotes that it was only a majority in part or a plurality. An asterisk in a joining vote denotes that the justice joined it only in part. A dash ( - ) denotes that the Justice concurred or dissented without filing a separate opinion.

Notes on statistics: Opinion counts only include the bench opinions listed above; opinions relating to orders or in-chambers opinions are not included. Agreement with the Court's judgment does not guarantee agreement with the reasoning expressed in its opinion. A justice is not considered in agreement if they dissented even in part. Agreement percentages are based only on the listed cases in which a justice participated and are rounded to the nearest one-tenth of one percentage point. Individual opinion counts will not match the Court's totals; Ginsburg and Breyer's jointly authored dissent in Comcast Corp. v. Behrend is counted separately for both justices but counted only once in the Court's totals.						Totals
