Of the hundreds of judges who have been impeached (W.O. Douglas twice) this may be the most bizarre:

140 federal judges
Atkins v. U.S., 214 Ct. Cl. 186, 556 F.2d 1028 (Ct. Cl. 1977), was an unsuccessful attempt to force the Government to address the destructive effect of inflation on the judiciary during the period 19691975, when the value of the dollar, measured by the Consumer Price Index, decreased by 34%, and Congress failed to provide increases to protect judges' purchasing power.
On March 2, 1976, Rep. Andrew Jacobs, Jr. introduced an impeachment resolution against Atkins and 139 other federal judges involved in the above-mentioned dispute. The resolution was referred to the Judiciary Committee.[190] and nothing was done. Mr. Jacobs introduced a second impeachment resolution against the same judges in a little more than a month The resolution was referred to the Judiciary Committee,[191] where it too, died.
