Roberts Court decisions

The Roberts Court is the time since 2005 during which the Supreme Court of the United States has been led by John Roberts as Chief Justice. Roberts succeeded William Rehnquist as Chief Justice after Rehnquist's death. It has been considered to be the most conservative court since the Vinson Court (1946–1953), with landmark rulings falling along partisan lines and very close confirmation votes for most of its members.

The ideology of the Roberts court was shaped early on by the retirement of the relatively moderate Justice Sandra Day O'Connor and the confirmation of the more conservative Justice Samuel Alito in 2006. The ideological balance shifted further rightward through the replacement of swing-vote Anthony Kennedy with Brett Kavanaugh in 2018 and the replacement of liberal Ruth Bader Ginsburg with Amy Coney Barrett in 2020. Some media outlets claim members of the Roberts court themselves are deeply politically polarized.
