How Supreme Court Justices Are Appointed and Confirmed

The U.S. Supreme Court is one of the most powerful institutions in government, and its justices serve for life. Because of this, the process of appointing and confirming a justice is carefully designed to balance the powers of the president and the Senate. Understanding this process helps explain why nominations often become high-stakes political events.

Step 1: A Vacancy Opens

A seat on the Supreme Court becomes available when a justice retires, resigns, passes away, or is removed (which has never happened). Since justices serve lifetime appointments, vacancies can be rare but have lasting impact.

Step 2: The President Selects a Nominee

The President of the United States chooses someone to fill the vacancy. Presidents typically consider:

Judicial experience (such as service on lower federal courts)
Legal philosophy (conservative, liberal, or moderate approaches)
Professional qualifications and reputation
Political factors, including how the nomination will be received in the Senate and by the public

Advisers, senators, and interest groups often play a role in shaping the president’s decision.

Step 3: Senate Judiciary Committee Review

The nomination is sent to the Senate Judiciary Committee, which investigates the nominee’s background, writings, and past rulings.

The committee holds confirmation hearings where the nominee answers questions from senators.
Witnesses, experts, and advocacy groups may testify for or against the nominee.

These hearings are often televised and widely covered, giving the public insight into the nominee’s views and qualifications.

Step 4: Committee Vote

After hearings, the Judiciary Committee votes on whether to send the nomination to the full Senate.

A favorable vote moves the nominee forward.
Even without a favorable recommendation, the Senate majority leader can still bring the nomination to the floor.

Step 5: Full Senate Debate and Vote

The full Senate debates the nomination. In the past, filibusters required 60 votes to end debate, but in 2017 the Senate changed its rules so that Supreme Court nominees can be confirmed with a simple majority (51 votes).

If the nominee receives a majority vote, they are confirmed.
If rejected, the president must choose another nominee.

Step 6: Appointment and Oath of Office

Once confirmed, the president signs a commission officially appointing the justice. The new justice then takes two oaths:

The Constitutional Oath (to support and defend the Constitution)
The Judicial Oath (to administer justice fairly and impartially)

Afterward, the justice takes their seat on the Supreme Court and begins hearing cases.

Why the Process Matters

Checks and Balances: The president nominates, but the Senate confirms, ensuring shared responsibility.
Lifetime Tenure: Because justices serve for life, each appointment can influence American law for decades.
Public Interest: Confirmation hearings give citizens a chance to see how nominees view major legal issues.

Final Thoughts

The appointment and confirmation of Supreme Court justices is one of the most consequential processes in U.S. government. It ensures that only nominees with both presidential support and Senate approval can serve on the nation’s highest court. Each justice shapes constitutional interpretation and, in turn, the daily lives of Americans for generations.
