Salary.
As of 2018, associate justices receive a yearly salary of $255,300 and the chief justice is paid $267,000 per year. Article III, Section 1 of the U.S. Constitution prohibits Congress from reducing the pay for incumbent justices. Once a justice meets age and service requirements, the justice may retire. Judicial pensions are based on the same formula used for federal employees, but a justice's pension, as with other federal courts judges, can never be less than their salary at the time of retirement.
Judicial leanings.
Although justices are nominated by the president in power, and receive confirmation by the Senate, justices do not represent or receive official endorsements from political parties, as is accepted practice in the legislative and executive branches. Jurists are, however, informally categorized in legal and political circles as being judicial conservatives, moderates, or liberals. Such leanings, however, generally refer to legal outlook rather than a political or legislative one. The nominations of justices are endorsed by individual politicians in the legislative branch who vote their approval or disapproval of the nominated justice. The ideologies of jurists can be measured and compared with several metrics, including the Segal–Cover score, Martin-Quinn score, and Judicial Common Space score.
Following the confirmation of Amy Coney Barrett in 2020, the Court currently consists of six justices appointed by Republican presidents and three appointed by Democratic presidents. It is popularly accepted that Chief Justice Roberts and associate justices Thomas, Alito, Gorsuch, Kavanaugh, and Barrett appointed by Republican presidents, compose the Court's conservative wing. Justices Breyer, Sotomayor and Kagan, appointed by Democratic presidents, compose the Court's liberal wing. Gorsuch had a track record as a reliably conservative judge in the 10th circuit. Kavanaugh was considered one of the more conservative judges in the DC Circuit prior to his appointment to the Supreme Court. Likewise, Barrett's brief track record on the Seventh Circuit is conservative. Prior to Justice Ginsburg's death, Chief Justice Roberts was considered the Court's median justice (in the middle of the ideological spectrum, with four justices more liberal and four more conservative than him), making him the ideological center of the Court.
