WASHINGTON — In an early sign of Justice Neil M. Gorsuch’s independence and work ethic, he has decided not to join a labor pool at the Supreme Court in which justices share their law clerks in an effort to streamline decisions about which cases to hear.

Justice Gorsuch joined the court last month. His decision not to participate in the pool was confirmed by Kathleen L. Arberg, the court’s public information officer. The only other member of the court who is not part of the arrangement is Justice Samuel A. Alito Jr.

Justices in the pool receive a common “pool memo” on each petition seeking Supreme Court review — more formally, “petition for certiorari” — from a single law clerk. The memo analyzes the petition and makes a recommendation about whether it should be granted.

As a law clerk to Justices Byron R. White and Anthony M. Kennedy in 1993 and 1994, a young Mr. Gorsuch wrote quite a few such memos.
