[Q]: 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.
[A]: can a seating supreme court justice be removed?


[Q]: The Tower of London, officially Her Majesty's Royal Palace and Fortress of the Tower of London, is a historic castle located on the north bank of the River Thames in central London. It lies within the London Borough of Tower Hamlets, separated from the eastern edge of the square mile of the City of London by the open space known as Tower Hill. It was founded towards the end of 1066 as part of the Norman Conquest of England. The White Tower, which gives the entire castle its name, was built by William the Conqueror in 1078 and was a resented symbol of oppression, inflicted upon London by the new ruling elite. The castle was used as a prison from 1100 (Ranulf Flambard) until 1952 (Kray twins), although that was not its primary purpose. A grand palace early in its history, it served as a royal residence. As a whole, the Tower is a complex of several buildings set within two concentric rings of defensive walls and a moat. There were several phases of expansion, mainly under Kings Richard I, Henry III, and Edward I in the 12th and 13th centuries. The general layout established by the late 13th century remains despite later activity on the site.
