none have been successfully removed through the complete impeachment and conviction process.
few Supreme Court justices have faced formal removal proceedings.
For history’s sake, there were 2 attempts;
Samuel Chase (1804)
Samuel Chase, an Associate Justice, was impeached by the House of Representatives in 1804 on charges of political bias and misconduct in his judicial role.
Justice Chase was accused of refusing to dismiss biased jurors and of excluding or limiting defense witnesses in two politically sensitive cases.
He was acquitted by the Senate in 1805. This case set an important precedent for judicial independence, establishing that judges could not be removed solely for their judicial decisions.

Abe Fortas (1969)
He was not not impeached, but Abe Fortas, an Associate Justice, resigned under pressure in 1969.
The ethics scandal involved financial arrangements with a foundation under investigation for securities violations.
