The selection of US Supreme Court justices

The selection process for U.S. Supreme Court justices has grown ever more complex. Presidents have the constitutional power to nominate justices, and, in doing so, they have employed several criteria at different times, including professional merit, ideological compatibility, and political support by the president and his advisers. Under the Constitution, the Senate has the authority to consent to or reject appointees. In recent decades it has used public hearings to ascertain a nominee's qualifications and, within certain limitations, the nominee's ideological attitudes. This process is intensely political and, as such, it reflects the Supreme Court's broad authority as the final interpreter of the Constitution, many of whose provisions raise highly contestable issues of great political significance. This article discusses these matters in light of Supreme Court appointments over the past century.
