From the abstract for Frank O. Bowman III, British Impeachments (1376 – 1787) & the Present American Constitutional Crisis (Aug. 14, 2018):
Impeachment is a British invention. It arose as one of a set of tools employed by Parliament in its long contest with the Crown over the reach of the monarch’s authority. British impeachment practice matters to Americans because the framers and ratifiers of the U.S. Constitution were the conscious heirs of Britain’s political evolution. The founders’ understanding of British history influenced their decision to include impeachment in the American constitution and their conception of how impeachment fit in a balanced system of ostensibly co-equal branches. It also produced two central features of American impeachment: the limitation of remedy to removal from office and the definition of impeachable conduct, particularly the famous phrase “high Crimes and Misdemeanors” adopted directly from British parliamentary language. Therefore, at a moment when impeachment talk is rampant, a reexamination of British impeachments is in order.
This Article is the first comprehensive analysis of the entire arc of British impeachments from 1376 to 1787 since Raoul Berger’s classic 1974 study. It gives particular attention to issues raised by the current presidency. The Article traces the evolution of Parliament’s use of impeachment and of the categories of behavior customarily designated as impeachable. These embraced, but were never limited to, indictable crimes, and included: armed rebellion and other overt treasons; common crimes like murder and rape; corruption (particularly the abuse of office for self-enrichment); incompetence, neglect, or maladministration of office; and betrayal of the nation’s foreign policy interests. The last of these categories has not been emphasized in modern American scholarship, but assumes particular salience in the present moment. Finally, and crucially, the Article concludes that, although Parliament sometimes used impeachment for less dramatic ends, its one indispensable function was removal of officials whose behavior threatened the constitutional order by promoting royal/executive absolutism over representative institutions and the rule of law. Critics of the incumbent president may find this thread of British precedent both poignant and potentially useful.
