Question: can the us president fire a supreme court justice

Answer: No, The Constitution provides that justices ``shall hold their offices during good behavior'' (unless appointed during a Senate recess). The term ``good behavior'' is understood to mean justices may serve for the remainder of their lives, unless they are impeached and convicted by Congress, resign, or retire. Only one justice has been impeached by the House of Representatives (Samuel Chase, March 1804), but he was acquitted in the Senate (March 1805). Moves to impeach sitting justices have occurred more recently (for example, William O. Douglas was the subject of hearings twice, in 1953 and again in 1970; and Abe Fortas resigned while hearings were being organized in 1969), but they did not reach a vote in the House. No mechanism exists for removing a justice who is permanently incapacitated by illness or injury, but unable (or unwilling) to resign.
