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.
