There have been 69  federal justices’ impeachment investigations since the 18th century, as of 2015.  The below list are the ones that were either removed or resigned from office to avoid public scrutiny.  Its interesting to note how many judge were impeached before and after the Judiciary became self-regulating in the 1960’s. So many investigations – and too many got away.
