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. It is generally considered to be more conservative than the preceding Rehnquist Court and the most conservative court since the Vinson Court of the 1940s and early 1950s. This is due to the retirement of moderate Justices Sandra Day O'Connor and Anthony Kennedy, the death of liberal Justice Ruth Bader Ginsburg, and the confirmation of conservative Justices Samuel Alito, Brett Kavanaugh, and Amy Coney Barrett in their places, respectively.
