Why Presidents Don’t Appoint Justices Alone

March 19, 2026

The Constitution establishes a shared process for selecting justices of the Supreme Court.

Under Article II of the Constitution, the president has the authority to nominate justices. But those nominees cannot take office unless they receive the advice and consent of the Senate, which today means confirmation by a majority vote.

Why did the Framers divide the appointment power this way?

Their goal was to prevent any single branch of government from exercising too much influence over the judiciary. The Supreme Court has the authority to interpret the Constitution and, in doing so, may invalidate laws passed by Congress or actions taken by the president. Because the Court wields such significant authority, the framers did not want its membership determined solely by one individual.

At the same time, they were wary of placing the appointment power entirely in the hands of the legislature. Large legislative bodies can be slow to act, subject to factional pressures, and influenced by shifting political coalitions. Giving Congress sole control over judicial appointments could have introduced its own risks to judicial independence.

The solution was a shared appointment process. The president selects a nominee, ensuring a clear point of leadership and accountability in the choice. The Senate then evaluates the nominee and must agree before the appointment becomes effective.

This arrangement reflects one of the central principles that runs throughout the Constitution: important governmental powers are often divided between institutions so that no single official can exercise them alone.

The process for selecting Supreme Court justices is one example of that broader design.
