Impeachment is a constitutional process by which a legislative body brings charges against a public official for alleged misconduct, potentially leading to removal from office. The procedure is distinct from a criminal trial; impeachment addresses violations of public trust, abuse of power, or other offenses defined by the governing charter or constitution.
Historical origins
The concept originates from English common law, where the Parliament held the authority to try and remove royal officials. The term derives from the Latin impetrare, meaning "to accuse." The modern application in democratic republics evolved from these precedents, adapting to separate powers and codified statutes.
Procedural framework
In systems with a separation of powers, impeachment typically involves two stages:
- Initiation and investigation – A lower legislative chamber (e.g., the House of Representatives in the United States) investigates alleged wrongdoing, often through committees, and may issue articles of impeachment if sufficient evidence exists.
- Trial and adjudication – The upper chamber (e.g., the Senate) conducts a trial, hearing evidence and arguments. A supermajority vote (commonly two‑thirds) is required to convict and remove the official; lesser majorities may result in censure or other sanctions.
Specific requirements, thresholds, and eligible offices vary among jurisdictions. Some constitutions limit impeachment to heads of state, ministers, judges, or other high officials, while others permit it for a broader class of public servants.
Legal standards and consequences
Impeachment does not itself impose criminal penalties; however, after removal, an official may still face criminal prosecution under ordinary law. The standards for impeachment are usually political rather than strictly legal, focusing on conduct that undermines the integrity of the office or violates constitutional duties.
Notable examples
- United States: The U.S. Constitution provides the impeachment mechanism (Article I, Sections 2 and 3). Presidents Andrew Johnson (1868), Bill Clinton (1998), and Donald J. Trump (2019 and 2021) were impeached by the House of Representatives; none were convicted by the Senate. Several federal judges have also been impeached and removed.
- United Kingdom: Historically, the British Parliament exercised impeachment against ministers; the last successful impeachment was that of Lord Chancellor Henry Dundas in 1806. The practice has fallen into disuse, supplanted by modern parliamentary mechanisms.
- Brazil: President Fernando Collor de Mello was impeached and removed in 1992; President Dilma Rousseff was impeached and removed in 2016, following votes in the Chamber of Deputies and the Federal Senate.
Comparative perspectives
While the basic premise—legislative removal of officials for misconduct—remains consistent, the precise rules differ. Some countries employ a judicial body to conduct the trial (e.g., the Constitutional Court of South Korea), whereas others rely solely on a legislative chamber. The required voting thresholds also vary, ranging from simple majorities to supermajorities.
Criticism and debate
Scholars and policymakers debate the appropriate balance between political accountability and protection against partisan abuse. Critics argue that low thresholds for initiating impeachment can incentivize partisan attacks, while proponents contend that a robust impeachment process is essential for upholding constitutional norms.
