Yes, presidents have nominated Supreme Court justices who were not judges many times. The Constitution gives no qualifications for Supreme Court judges, so the President can nominate anyone he wants. Today, nominating judges is the norm, but that was not so in the past.
True- such is how Supreme Court Justices are chosen.
John Jay
Just that: the Supreme Court of Justice of the Nation (Spanish: Suprema Corte de Justicia de la Nacion). It consists of a President of the Supreme Court (Chief Justice) and ten Ministers (Associate Justices) who are confirmed by the Senate from a list proposed by the Mexican President.
Justices of the Supreme Court are nominated by the President and confirmed by Congress. The criteria by which a President chooses the candidates would include legal expertise, and political compatibility with the President's own policies.
Barack Obama does meet the qualifications to be a Supreme Court Justice, as outlined in the U.S. Constitution. However, it is ultimately up to the President to nominate individuals for the role, and it is not guaranteed that he would be chosen. Additionally, being a former President does not assure eligibility or appointment to the Supreme Court.
He (or she) is nominated by the President of the United States and confirmed by a simple majority (51%) vote of the Senate. All Supreme Court Justices are nominated by the president; no person becomes a Supreme Court Justice without a presidential nomination. Nominees are then voted on by the Senate. If the Senate rejects a nominee, which does happen, then the president chooses another nominee. If the President selects an Associate Justice to become Chief Justice, he or she is said to be "elevated," rather than appointed. The Chief Justice remains Chief Justice until resignation (or death), and the person nominated by the president to take the vacant seat becomes the Chief Justice.
The state that Samuel Chase represented was Maryland. He served as Chief Justice in Baltimore until he was chosen by President Washington to serve on the Supreme Court.
US Supreme Court justices are chosen (nominated) by the President and approved by a simple majority vote of the Senate.
The president gets to choose the justices himself
While the Constitution mandates the Oath itself, it does not specify who should administer it. Typically, the Chief Justice of the U. S. Supreme Court is chosen, however other judges have also been selected.
Supreme Court justices are chosen by the president of the United States with the approval from the Senate.
When nominating a Supreme Court justice, the president reviews potential candidates and selects an individual who they believe is qualified and aligned with their own judicial philosophy. The president then officially announces the nominee, who must undergo a confirmation process by the Senate Judiciary Committee and the full Senate before they can take the position. The president's role is to make the nomination and advocate for their chosen candidate, while the Senate ultimately decides whether to confirm the nominee.
