Law clerks

Each Supreme Court justice hires several law Clerks to review petitions for writ of certiorari, research them, prepare bench memorandums, and draft opinions. Associate justices are allowed four clerks. The chief justice is allowed five clerks, but Chief Justice Rehnquist hired only three per year, and Chief Justice Roberts usually hires only four. Generally, law clerks serve a term of one to two years.

The first law clerk was hired by Associate Justice Horace Gray in 1882. Oliver Wendell Holmes, Jr. and Louis Brandeis were the first Supreme Court justices to use recent law school graduates as clerks, rather than hiring a "stenographer-secretary". Most law clerks are recent law school graduates.

The first female clerk was Lucile Lomen, hired in 1944 by Justice William O. Douglas. The first African-American, William T. Coleman, Jr., was hired in 1948 by Justice Felix Frankfurter. A disproportionately large number of law clerks have obtained law degrees from elite law schools, especially Harvard, Yale, the University of Chicago, Columbia, and Stanford. From 1882 to 1940, 62% of law clerks were graduates of Harvard Law School. Those chosen to be Supreme Court law clerks usually have graduated in the top of their law school class and were often an editor of the law review or a member of the moot court board. By the mid-1970s, clerking previously for a judge in a federal court of appeals had also become a prerequisite to clerking for a Supreme Court justice.

Nine Supreme Court justices previously clerked for other justices: Byron White for Frederick M. Vinson, John Paul Stevens for Wiley Rutledge, William Rehnquist for Robert H. Jackson, Stephen Breyer for Arthur Goldberg, John Roberts for William Rehnquist, Elena Kagan for Thurgood Marshall, Neil Gorsuch for both Byron White and Anthony Kennedy, Brett Kavanaugh also for Kennedy, and Amy Coney Barrett for Antonin Scalia. Justices Gorsuch and Kavanaugh served under Kennedy during the same term. Gorsuch is the first justice to serve alongside a justice for whom he or she clerked, serving alongside Kennedy from April 2017 through Kennedy's retirement in 2018. With the confirmation of Justice Kavanaugh, for the first time a majority of the Supreme Court was composed of former Supreme Court law clerks (Roberts, Breyer, Kagan, Gorsuch and Kavanaugh, now joined by Barrett).

Several current Supreme Court justices have also clerked in the federal courts of appeals: John Roberts for Judge Henry Friendly of the United States Court of Appeals for the Second Circuit, Justice Samuel Alito for Judge Leonard I. Garth of the United States Court of Appeals for the Third Circuit, Elena Kagan for Judge Abner J. Mikva of the United States Court of Appeals for the District of Columbia Circuit, Neil Gorsuch for Judge David B. Sentelle of the United States Court of Appeals for the District of Columbia, Brett Kavanaugh for Judge Walter Stapleton of the United States Court of Appeals for the Third Circuit and Judge Alex Kozinski of the United States Court of Appeals for the Ninth Circuit, and Amy Coney Barrett for Judge Laurence Silberman of the U.S. Court of Appeals for the D.C. Circuit.

Politicization of the Court

Clerks hired by each of the justices of the Supreme Court are often given considerable leeway in the opinions they draft. "Supreme Court clerkship appeared to be a nonpartisan institution from the 1940s into the 1980s," according to a study published in 2009 by the law review of Vanderbilt University Law School. "As law has moved closer to mere politics, political affiliations have naturally and predictably become proxies for the different political agendas that have been pressed in and through the courts," former federal court of appeals judge J. Michael Luttig said. David J. Garrow, professor of history at the University of Cambridge, stated that the Court had thus begun to mirror the political branches of government. "We are getting a composition of the clerk workforce that is getting to be like the House of Representatives," Professor Garrow said. "Each side is putting forward only ideological purists."

According to the Vanderbilt Law Review study, this politicized hiring trend reinforces the impression that the Supreme Court is "a superlegislature responding to ideological arguments rather than a legal institution responding to concerns grounded in the rule of law". A poll conducted in June 2012 by The New York Times and CBS News showed just 44% of Americans approve of the job the Supreme Court is doing. Three-quarters said justices' decisions are sometimes influenced by their political or personal views.
