Which of the following is NOT a requirement for serving as a Supreme Court Justice?

Serving as a Supreme Court Justice does not have a specified minimum age requirement set by the U.S. Constitution. The only qualifications for becoming a Supreme Court Justice, as stated in Article II, Section 2 of the Constitution, are that the individual must be appointed by the President and confirmed by the Senate. While traditionally Justices have been experienced legal professionals, there is no formal age stipulated, allowing someone to potentially serve regardless of their age, as long as they meet the appointment criteria.

Citizenship, length of service, and appointment by the President are indeed essential for serving on the Supreme Court. A Justice must be a natural-born or naturalized citizen, and they must be appointed by the President, confirmed by the Senate to hold their position. Additionally, although there is no official requirement for length of service, once appointed, Justices typically serve for life unless they resign, retire, or are removed, reflecting an unwritten expectation of tenure. Thus, the absence of a minimum age distinctly sets that specific option apart as not a requirement for the role.
