Impeachment

Impeachment is a formal process for bringing charges against a public official under constitutional or parliamentary authority. In its narrower sense, it denotes the accusation rather than the subsequent trial or removal; the term is also used more broadly for the proceedings as a whole. The officials subject to impeachment, the grounds for charges, and the institutions responsible for judgment differ between jurisdictions. In the United States, the House of Representatives impeaches federal officials and the Senate tries the charges; in South Korea, the National Assembly brings impeachment proceedings before the Constitutional Court. (senate.gov)

Impeachment provides a means of holding senior officeholders accountable for specified violations of law or abuses of public authority. It developed in medieval England and subsequently became part of several constitutional systems. Its significance lies in the relationship between official accountability and the protection of public office from arbitrary removal. Understanding the institution requires distinguishing accusation from conviction, examining its historical development and national procedures, and explaining how impeachment judgments relate to removal, disqualification, criminal proceedings, and judicial review. (constitution.congress.gov)

Meaning and Constitutional Function

In its narrow constitutional sense, impeachment is the formal accusation of a public official by the institution authorized to bring charges; it is not itself a finding of guilt or an act of removal. The United States Constitution separates accusation from adjudication: Article I gives the House of Representatives the power to impeach and the Senate the power to try impeachments. The House adopts articles of impeachment by a simple majority, whereas conviction requires two-thirds of senators present. An investigation gathers information, a trial determines the charges, conviction sustains them, and removal terminates the official’s tenure. These are distinct acts: an official may be impeached and subsequently acquitted. In broader usage, “impeachment” or “the impeachment process” also denotes the proceedings as a whole, encompassing accusation, trial, and possible sanctions. (senate.gov)

The constitutional function is to make senior officeholders accountable for specified misconduct and to provide an institutional check on executive and judicial authority. In the United States, impeachment forms part of the separation of powers: Congress can bring proceedings against the president and federal judges, although those officials do not ordinarily depend on congressional confidence to retain office. Article II, Section 4 identifies treason, bribery, and other high crimes and misdemeanors as grounds for removal following impeachment and conviction. The mechanism addresses violations of law and abuses of official power through a constitutional procedure, rather than simply transferring an ordinary criminal prosecution to the legislature. Its “political” character concerns public office, institutional responsibility, and the exercise of governmental authority, not merely competition between political parties. (constitution.congress.gov)

Impeachment and criminal law nevertheless have separate purposes and consequences, even when they concern the same conduct. Under Article I, Section 3, Clause 7 of the United States Constitution, an impeachment judgment cannot extend beyond removal and disqualification from future federal office; it does not authorize imprisonment or a criminal fine. The clause separately preserves the convicted person’s liability to indictment, trial, judgment, and punishment according to law. Thus, the use of terms such as “charges,” “trial,” and “conviction” does not make an impeachment proceeding an ordinary criminal case, and its judgment does not itself determine criminal liability. (senate.gov)

A vote of no confidence is a different basis for ending an administration’s tenure: it concerns whether the executive retains legislative support rather than whether specified grounds for exceptional removal have been established. South Africa expresses the distinction in separate provisions of its 1996 Constitution. Section 89 permits the National Assembly to remove the president with support from at least two-thirds of all its members, but only for a serious violation of the Constitution or law, serious misconduct, or inability to perform the functions of office. Section 102(2), by contrast, requires the president, other Cabinet members, and deputy ministers to resign after a presidential no-confidence motion supported by a majority of Assembly members; it does not prescribe Section 89’s grounds. Section 102(1) separately provides that loss of confidence in the Cabinet excluding the president requires the president to reconstitute the Cabinet. (gov.za)

The meaning and operation of impeachment therefore depend on the relevant constitutional text, procedural rules, and institutional practice. Even within one jurisdiction, broad constitutional language may acquire specificity through successive proceedings. The United States’ Constitution Annotated identifies House practice as a source of impeachment doctrine: Joseph Story’s 1833 Commentaries on the Constitution anticipated that the scope of impeachable political offenses would develop over time rather than through an exhaustive statutory definition. Parliamentary precedents consequently help explain how constitutional powers have been exercised, but they are not interchangeable with binding judicial interpretations. (constitution.congress.gov)

English Origins and Parliamentary Development

The first recorded English parliamentary impeachment occurred in 1376, when Lord Latimer was accused during the “Good Parliament” of Edward III’s reign. The proceedings established a division of functions: the House of Commons brought accusations against royal servants, while the House of Lords adjudicated them. This enabled representatives in the Commons to challenge the conduct of the king’s advisers without prosecuting the king himself. The procedure subsequently became a recurring instrument of conflict over royal administration; in 1386, the Commons secured the dismissal of Richard II’s lord chancellor and then impeached him. (commonslibrary.parliament.uk)

English impeachment reached ministers, royal favourites, and other subjects, including private persons, whose alleged misconduct damaged the state or subverted government. Its importance lay partly in addressing abuses of power that ordinary common-law criminal courts could not effectively reach. Parliament could therefore constrain the Crown indirectly by prosecuting those who exercised authority on its behalf. Unlike constitutional systems that restrict impeachment judgments to removal or disqualification, English convictions could result in fines, imprisonment, or death. The phrase “high crimes and misdemeanours” developed within this parliamentary practice as a description of serious abuses, rather than as a fixed catalogue of statutory offences. (constitution.congress.gov)

Use of the procedure was intermittent. The House of Commons Library records fewer than seventy impeachments across English history, approximately a quarter of them occurring between 1640 and 1642. In the developed procedure, the Commons approved charges and appointed managers to prosecute before the Lords, who heard the evidence and delivered judgment. These were distinct institutional acts: accusation by the Commons did not establish guilt. Thomas Erskine May’s first parliamentary treatise, published in 1844, described the Lords as performing both judicial and jury functions, reflecting impeachment’s combination of parliamentary authority and adjudication. (commonslibrary.parliament.uk)

The proceedings against Warren Hastings demonstrated the procedure’s application to imperial administration. Hastings, formerly governor-general of Bengal under the East India Company, was impeached in 1787 following a campaign led by Edmund Burke alleging misrule and corruption. His trial before the Lords began in Westminster Hall in 1788 and continued until April 1795. Although it occupied seven years, the court sat for 142 days; Hastings was acquitted of all sixteen charges. The final British impeachment was that of Henry Dundas, Viscount Melville. The Commons initiated proceedings in 1805 over alleged misuse of public money associated with his service as treasurer of the navy. His trial took place in 1806 and likewise ended in acquittal. (parliament.uk)

Impeachment became obsolete as ministerial responsibility and other mechanisms of executive accountability developed within the parliamentary system. Parliamentary questions, committee inquiries, confidence motions, and judicial review supplied alternative means of scrutiny or control without requiring an impeachment trial. Obsolescence did not, however, amount to formal abolition. The Select Committee on Parliamentary Privilege recommended legislative abandonment in 1967, and the recommendation was repeated in 1976–77, but neither produced abolition legislation. The Joint Committee on Parliamentary Privilege concluded in 1999 that the historical circumstances of impeachment were sufficiently remote for the procedure to be considered obsolete. Its rules had not been reconstructed for modern democratic institutions or standards of procedural fairness. (commonslibrary.parliament.uk)

Officials Subject to Impeachment and Grounds for Charges

Constitutional eligibility for impeachment depends on the office held, not simply on an allegation of serious misconduct. Article II, Section 4 of the United States Constitution covers the president, vice president, and federal civil officers, including federal judges and senior executive officials such as cabinet secretaries. It does not make every public employee impeachable, and congressional practice excludes members of Congress. The proceedings against Senator William Blount, dismissed for lack of jurisdiction in 1799, are generally understood as establishing that exclusion. Legislators instead face their own chamber’s disciplinary authority: Article I, Section 5 permits each house to punish members and, with a two-thirds vote, expel them. Federal impeachment also does not extend to state officials merely because they exercise public authority. (constitution.congress.gov)

The United States grounds are treason, bribery, and “high Crimes and Misdemeanors.” Treason has a separate constitutional definition in Article III: levying war against the United States or adhering to its enemies by giving them aid and comfort. The broader impeachment phrase is not defined by a statutory list of offenses. Its historical meaning encompasses serious abuses of public authority and breaches of official trust, rather than corresponding to the modern distinction between felonies and misdemeanors in criminal law. Congressional impeachment practice has not required every charge to allege an indictable criminal offense; conversely, the existence of a criminal violation does not by itself settle whether conduct warrants impeachment. At the 1787 Constitutional Convention, George Mason proposed adding maladministration as a ground, but James Madison objected that this would make presidential tenure dependent on the Senate’s pleasure; the convention adopted the high-crimes-and-misdemeanors formulation instead. (senate.gov)

The Philippines uses a narrower enumeration of eligible offices. Article XI, Section 2 of its 1987 Constitution names the president, vice president, Supreme Court members, members of the Constitutional Commissions, and the Ombudsman. The commissions are the Civil Service Commission, Commission on Elections, and Commission on Audit. Cabinet ministers and lower-court judges are not included: the same section expressly states that other public officers and employees may be removed as provided by law, but not through impeachment. Its grounds comprise culpable constitutional violation, treason, bribery, graft and corruption, other high crimes, and betrayal of public trust. The last category expressly identifies breach of public trust as a constitutional ground alongside offenses such as bribery; it is not merely another name for treason or corruption. (officialgazette.gov.ph)

Article 65 of South Korea’s Constitution reaches a broader range of executive, judicial, and oversight offices. It covers the president, prime minister, State Council members, heads of executive ministries, Constitutional Court justices, judges, National Election Commission members, and the chairperson and commissioners of the Board of Audit and Inspection, together with other officials designated by law. The stated ground is violation of the Constitution or other laws in performing official duties. The connection to official duties is therefore part of the constitutional test, rather than an assumption that any unlawful private conduct necessarily supplies grounds. (ccourt.go.kr)

In Brazil, Article 85 of the 1988 Constitution defines presidential crimes de responsabilidade, or crimes of responsibility, as acts attacking the federal Constitution, especially seven protected interests: the Union’s existence; the free exercise of constitutional institutions; political, individual, and social rights; internal security; administrative probity; the budget law; and compliance with laws and judicial decisions. It requires special legislation to define these offenses and their procedures. Article 86 distinguishes them from ordinary criminal offenses, assigning presidential responsibility cases to the Senate and ordinary criminal cases to the Supreme Federal Court. Thus, an allegation concerning budget-law compliance belongs to an expressly identified constitutional category, rather than necessarily requiring classification as an ordinary criminal offense. (planalto.gov.br)

Initiation, Investigation, and Formal Charges

In the United States, Article I, Section 2 of the Constitution assigns the sole power of impeachment to the House of Representatives. Proceedings commonly begin with a member introducing a resolution or declaring charges, although petitions, a grand jury, or a state legislature may also request an investigation. Such requests do not themselves impeach an official: the House retains discretion over whether to proceed. Investigations ordinarily fall to the Judiciary Committee, sometimes through a subcommittee or specially established task force. A resolution authorizing an inquiry and a resolution adopting charges perform different functions; the former establishes or supports fact-finding, whereas the latter formally accuses the official. (constitution.congress.gov)

The Philippines provides more explicit filing requirements in Article XI, Section 3 of its 1987 Constitution. A verified complaint may be filed by a House member, or by a citizen with a resolution or endorsement from a member. Under the ordinary committee route, the complaint must enter the Order of Business within ten session days and be referred to the appropriate committee within three session days thereafter. After a hearing, the committee must submit a report and corresponding resolution within sixty session days of referral, with approval by a majority of all its members. The House must place the resolution on its agenda within ten session days of receipt. These are constitutional deadlines expressed in session days, rather than a uniform number of elapsed calendar days. (comelec.gov.ph)

Committee investigation assembles the factual record on which proposed charges rest. United States House committees may subpoena witnesses and written records, question witnesses at hearings, and examine material supplied by other investigations. Particular inquiries may receive additional authority or adopt special procedures concerning depositions, confidential evidence, and participation by the official’s counsel. In the 1998 inquiry concerning President Bill Clinton, the Judiciary Committee held four hearings, including testimony from nineteen impeachment experts at one hearing, the independent counsel at another, and White House counsel during two days in December. Investigation therefore need not duplicate every evidentiary step already undertaken elsewhere, but the committee must decide what recommendation to make to the House. (congress.gov)

Formal allegations are organized into articles of impeachment, which can distinguish separate acts or courses of conduct. In United States practice, articles are normally contained in a simple House resolution. Committee consideration, known as markup, permits debate and amendment before a recommendation is reported; the full House may vote separately on individual articles, and adoption requires a simple majority. Committee approval alone is not impeachment. This distinction was illustrated in 1974: the Judiciary Committee approved three articles against President Richard Nixon on July 27, 29, and 30, by votes of 27–11, 28–10, and 21–17, respectively. Nixon resigned on August 9 before the full House voted, so the committee’s action did not become a House impeachment. (congress.gov)

Philippine voting thresholds differ from the United States rule. At least one-third of all House members must vote either to affirm a favorable committee resolution containing articles or to override an unfavorable resolution; each member’s vote must be recorded. Article XI also provides an alternative route: a verified complaint or impeachment resolution filed by at least one-third of all House members itself constitutes the articles, with Senate trial to follow. This route does not require the ordinary committee recommendation followed by a separate chamber vote adopting articles. (elibrary.judiciary.gov.ph)

Once the United States House adopts articles, it appoints members by resolution to act as impeachment managers. These representatives transmit and present the charges to the Senate and conduct the House’s case there, performing a prosecutorial role rather than adjudicating the allegations. Managers have historically often come from the Judiciary Committee, but neither their number nor their selection is constitutionally fixed. Transmission carries the accusation from the charging chamber to the institution responsible for trial; it does not establish that the charges have been proved. (constitution.congress.gov)

Adjudication, Evidence, and Voting

In the United States, impeachment adjudication belongs to the Senate rather than an ordinary court. Senators sit under oath or affirmation, receive the case, and decide whether the charges warrant conviction; members of the House of Representatives appointed as impeachment managers act as prosecutors. The chief justice presides when a president is tried, but the Senate retains the constitutional authority to decide the case. The Philippines similarly assigns trial and decision to its Senate under the 1987 Constitution. Its senators also take an oath or affirmation, and its chief justice presides without voting when the president is the respondent. These arrangements place adjudicative responsibility in a legislative chamber, even when a judicial officer conducts the proceedings. (senate.gov)

The United States Senate’s procedural rules provide for a summons reciting the articles and directing the respondent to appear and answer them. Appearance may be personal or through counsel; failure to appear or answer does not automatically establish guilt, because proceedings continue as though a not-guilty plea had been entered. Counsel may present arguments and objections, and witnesses are examined by the party producing them and cross-examined by the opposing side. The presiding officer may rule on relevance, materiality, and other evidentiary questions, but a senator may require the chamber to vote on a ruling. Rule XI also permits a committee of senators to receive evidence and testimony and transmit a certified record to the full Senate. These are institutional rules, not a universal impeachment procedure. (senate.gov) The Constitution specifies no standard of proof, and the Senate has not adopted a uniform one binding senators in every impeachment trial; the criminal standard of proof beyond reasonable doubt therefore cannot simply be assumed to govern. (congress.gov)

In South Korea, the National Assembly brings the accusation, but a constitutional court adjudicates it. The chair of the Assembly’s Legislation and Judiciary Committee serves as impeachment prosecutor, submitting the adopted resolution and participating in proceedings against the respondent. The Court conducts oral hearings, while its presiding justice directs arguments and maintains courtroom order. Evidence examination may occur on a party’s motion or on the Court’s own initiative, including examination of witnesses, requests for documents, appraisal, and inspection. The Court may also request information from public bodies, subject to statutory restrictions. Nonattendance has a different procedural treatment from the American rule: an initial failure to attend requires a rescheduled hearing, but adjudication may proceed if the party again fails to attend. (ccourt.go.kr)

The majority required to bring charges is distinct from the majority required to sustain them. In the United States, the House adopts articles by a simple majority, whereas conviction requires two-thirds of senators present. Senate rules provide for a separate vote on each article; conviction on any one article is sufficient. With 100 senators present, 67 affirmative votes are necessary, but with 90 present, 60 suffice. (senate.gov) The practical significance appeared in Andrew Johnson’s trial: on May 16, 1868, 35 senators voted guilty and 19 not guilty on Article XI, falling one vote short of the required 36. (senate.gov) In the Philippines, at least one-third of all House members must support the articles through the constitutional routes, while conviction requires two-thirds of all Senate members, not merely those present. For a Senate with all 24 seats filled, this means 16 votes. (officialgazette.gov.ph)

South Korea’s final decision instead requires the concurrence of at least six Constitutional Court justices to uphold impeachment and remove the respondent. The Court’s full complement is nine justices, but the six-vote requirement is a fixed number rather than a fraction recalculated according to attendance. It is also separate from the National Assembly’s vote adopting the accusation: parliamentary approval sends the case to the Court, while judicial concurrence determines whether impeachment is sustained. Thus, even unanimous agreement among fewer than six participating justices would not satisfy the constitutional requirement for removal. (ccourt.go.kr)

Judgments and Their Legal Consequences

Removal terminates an official’s tenure; suspension during proceedings temporarily prevents the exercise of official powers without itself deciding the charges. In South Korea, Article 65(3) of the Constitution suspends the powers of an official once the National Assembly passes an impeachment motion, pending adjudication. Removal follows only if the Constitutional Court upholds the request. Article 65(4) limits the impeachment judgment to removal, while the Constitutional Court Act attaches a further consequence: a person removed by an impeachment decision cannot become a public official for five years from the decision’s pronouncement. The initial parliamentary accusation, interim suspension, and final loss of office therefore have distinct legal effects. (ccourt.go.kr)

Disqualification concerns eligibility for subsequent office rather than possession of the office already held. Under the United States Constitution, Article II, Section 4 makes removal mandatory upon impeachment and conviction of a serving officer; Article I, Section 3, Clause 7 also permits disqualification from offices of honor, trust, or profit under the United States. Senate practice treats disqualification as an additional, discretionary judgment, not an automatic consequence of conviction. After conviction by two-thirds of senators present, the Senate may impose disqualification through a separate simple-majority vote. That lower threshold rests on institutional precedent rather than an express constitutional voting rule. In South Africa, by contrast, Section 89(2) automatically excludes a president removed for serious constitutional or legal violations, or serious misconduct, from any public office and from receiving benefits of the presidency. Those additional consequences do not attach under that subsection to removal for inability to perform presidential functions. (govinfo.gov)

An impeachment judgment does not itself impose imprisonment, a criminal fine, or other punishment under criminal law. The United States Impeachment Judgment Clause expressly preserves the possibility of indictment, trial, judgment, and punishment through ordinary legal proceedings after conviction. South Korea’s Constitution similarly states that an impeachment decision does not exempt the removed official from civil or criminal liability. These provisions preserve separate proceedings; they do not establish criminal guilt or dispense with the requirements governing prosecution. In Trump v. United States (2024), the United States Supreme Court also rejected the contention that impeachment and Senate conviction were necessary prerequisites to criminal prosecution of a former president, while separately addressing presidential immunity. (constitution.congress.gov)

Resignation or expiration of a term can eliminate the practical possibility of removal without necessarily ending proceedings concerning disqualification. On March 2, 1876, United States Secretary of War William Belknap resigned before the House impeached him later that day. The Senate nevertheless accepted jurisdiction and tried the five articles; on August 1 it acquitted him because no article received the required two-thirds vote. A later institutional decision occurred on February 9, 2021, when the Senate voted 56–44 that Donald Trump’s second impeachment trial was constitutional after his presidential term had ended. These decisions establish Senate precedents for adjudicating charges against former officials, rather than a universally accepted rule governing every post-office case. (senate.gov)

In Brazil, Fernando Collor resigned on December 29, 1992, after his Senate trial had begun, but the proceedings continued to judgment. Senate Resolution No. 101, dated December 30, explicitly treated the requested loss-of-office sanction as moot because of his resignation and terminated that portion of the case. It nevertheless sustained the accusation of crimes of responsibility and imposed an eight-year disqualification from exercising public functions under Article 52 of the Constitution. The resolution also preserved any other applicable judicial sanctions. Its operative distinction was therefore between an office Collor had already relinquished and a remaining sanction affecting his future eligibility for public service. (www2.camara.leg.br)

United States Constitutional Design and Historical Cases

The United States Constitution, drafted in 1787, divided impeachment authority between the two chambers of Congress rather than assigning both accusation and judgment to one institution. Article I, Section 2 gives the House of Representatives the sole power of impeachment; Section 3 gives the Senate the sole power to try impeachments and requires two-thirds of senators present for conviction. When the president is tried, the chief justice presides, but senators determine the verdict. Article II, Section 4 identifies the president, vice president, and federal civil officers as subject to removal following impeachment and conviction for treason, bribery, or other high crimes and misdemeanors. This allocation places an exceptional removal power within the constitutional separation of powers. (archives.gov)

Early cases established important institutional precedents. The House impeached Tennessee senator William Blount on July 7, 1797; the Senate separately expelled him the following day and dismissed the impeachment charges for lack of jurisdiction on January 11, 1799. Supreme Court justice Samuel Chase was impeached in 1804 on eight articles concerning his judicial conduct. On March 1, 1805, the Senate acquitted him on every article: three attracted majorities for conviction, but none reached two-thirds. Secretary of War William Belknap resigned on March 2, 1876, before the House impeached him that day over payments associated with a military trading-post appointment. The Senate voted to retain jurisdiction despite his resignation, but acquitted him on all five articles on August 1, 1876. (senate.gov)

Andrew Johnson became the first president impeached by the House on February 24, 1868, by a vote of 126–47. The principal charges arose from his attempt to remove Secretary of War Edwin M. Stanton contrary to the Tenure of Office Act. Chief Justice Salmon P. Chase presided over the trial. On May 16 and May 26, the Senate voted on three of the eleven articles; each received 35 guilty votes and 19 not-guilty votes, one vote short of conviction. Johnson therefore remained in office. Richard Nixon’s case ended at a different stage: the House Judiciary Committee recommended articles alleging obstruction of justice, abuse of power, and contempt of Congress on July 27, 29, and 30, 1974. Nixon resigned effective August 9, before the full House voted; he was neither formally impeached nor tried by the Senate. (senate.gov)

The House impeached Bill Clinton on December 19, 1998, for perjury before a federal grand jury and obstruction of justice. On February 12, 1999, the Senate acquitted him: the perjury article received 45 guilty votes against 55 not-guilty votes, while obstruction received 50–50. Neither met the required two-thirds threshold. (history.house.gov)

Donald Trump was impeached on December 18, 2019, on articles alleging abuse of power and obstruction of Congress. On February 5, 2020, the Senate acquitted him, with guilty/not-guilty totals of 48–52 and 47–53, respectively. The House impeached him again on January 13, 2021, on one article alleging incitement of insurrection in connection with the January 6 attack on the Capitol. His second trial concluded after his presidential term had ended: on February 13, 2021, 57 senators voted guilty and 43 not guilty, again insufficient for conviction. (history.house.gov)

Federal judicial impeachments constitute a substantial part of the historical record. District judge John Pickering was convicted and removed on March 12, 1804, the first federal official removed through impeachment. Later judicial removals included Robert Archbald in 1913, Halsted Ritter in 1936, and three judges during the 1980s. On December 8, 2010, the Senate convicted Louisiana district judge G. Thomas Porteous Jr. on all four articles and removed him; the first article received a unanimous 96–0 vote for conviction. (senate.gov)

Brazil and the Philippines

In Brazil, the 1988 Constitution divides responsibility for presidential impeachment between the Chamber of Deputies and the Federal Senate. Article 51 requires authorization by two-thirds of the Chamber’s members before proceedings can be instituted; Article 52 assigns prosecution and judgment for crimes de responsabilidade—“crimes of responsibility”—to the Senate. The president of the Supreme Federal Court presides over the trial, and conviction requires two-thirds of the Senate’s votes. The constitutional penalty is removal with eight years’ disqualification from exercising public functions, without prejudice to other judicial sanctions. Article 85 identifies acts against the Constitution, including attacks on administrative probity and budgetary law, and requires special legislation to define the offenses and trial procedure. Law No. 1,079 of April 10, 1950 supplies this statutory framework. (legis.senado.leg.br)

Fernando Collor de Mello’s proceedings followed a congressional investigation into allegations involving his former campaign treasurer, Paulo César Farias. On September 29, 1992, the Chamber authorized proceedings by 441 votes to 38, with one abstention. The Senate instituted the case on October 1, and Collor was temporarily suspended on October 2, when Vice-President Itamar Franco assumed presidential duties. Collor resigned on December 29, after the final trial session had begun, but the Senate continued adjudication. Its judgment, recorded in Resolution No. 101 of December 30, imposed eight years’ disqualification from public functions; the vote was 76 to 3. This parliamentary disposition was separate from the Supreme Federal Court’s December 1994 acquittal of Collor on the passive-corruption charge in Criminal Action 307, for insufficient evidence of his participation in the alleged conduct. (www2.camara.leg.br)

On August 31, 2016, the Senate removed Dilma Rousseff by 61 votes to 20 in a trial presided over by Supreme Federal Court President Ricardo Lewandowski. The Senate held her responsible for issuing three supplementary-credit decrees without legislative authorization and delaying subsidy transfers to Banco do Brasil under the agricultural Plano Safra program, contrary to budgetary and fiscal laws. Removal and disqualification were put to separate votes. In the second ballot, 42 senators supported disqualification, 36 opposed it, and three abstained: support fell short of the required 54 votes. Rousseff therefore lost the presidency but was not disqualified from exercising public functions. Michel Temer, who had served as acting president during her suspension, was sworn in as president that day. (www12.senado.leg.br)

In the Philippines, Article XI of the 1987 Constitution limits impeachment to the president, vice-president, Supreme Court members, members of the constitutional commissions, and the ombudsman. The commissions are the Civil Service Commission, Commission on Elections, and Commission on Audit. Grounds comprise culpable constitutional violation, treason, bribery, graft and corruption, other high crimes, and betrayal of public trust; other public officers are removable through different legal procedures. The House of Representatives exclusively initiates impeachment. A verified complaint may come from a representative or a citizen endorsed by a representative. At least one-third of all House members must approve articles; a complaint filed by that proportion itself constitutes the articles. Proceedings cannot be initiated against the same official more than once within one year. The Senate exclusively tries cases, with conviction requiring two-thirds of all its members. In presidential trials, the Supreme Court’s chief justice presides without voting. Judgment is limited to removal and disqualification from office, while separate prosecution remains possible. (officialgazette.gov.ph)

South Korea’s Constitutional-Court Model

Article 65 of South Korea’s Constitution authorizes the National Assembly to impeach specified officials for violations of the Constitution or statutes committed in performing their official duties. The offices covered include the president, prime minister, ministers, judges, Constitutional Court justices, and members of designated constitutional bodies. A presidential motion requires proposal by a majority of the Assembly’s total membership and approval by at least two-thirds; for other covered officials, the corresponding thresholds are one-third for proposal and a majority for passage. These are thresholds for legislative accusation, not final removal. (law.go.kr) The chair of the Assembly’s Legislation and Judiciary Committee acts as impeachment prosecutor and submits the resolution to the Constitutional Court. Passage suspends the respondent’s official powers pending judgment; removal requires at least six justices’ concurrence. (ccourt.go.kr)

The Court established a substantive distinction between unlawful conduct and misconduct warranting presidential removal in 2004Hun-Na1, decided on May 14, 2004. The Assembly had impeached President Roh Moo-hyun on March 12 with 193 affirmative votes. The Court found violations involving electoral impartiality and the president’s duty to protect the Constitution, but rejected removal. It interpreted Article 53(1) of the Constitutional Court Act as requiring a sufficiently grave violation, rather than treating every constitutional or statutory breach as grounds for dismissal. For a president, the inquiry was whether continued tenure was incompatible with constitutional protection or whether betrayal of public trust disqualified the president from administering state affairs. Roh’s violations did not meet that standard. (english.ccourt.go.kr)

President Park Geun-hye’s case, 2016Hun-Na1, produced the opposite disposition. The Assembly approved impeachment on December 9, 2016, with 234 affirmative votes; all eight participating justices ordered her removal on March 10, 2017. (english.ccourt.go.kr) The Court found that Park had used presidential authority to advance the private interests of her acquaintance Choi Seo-won, also known as Choi Soon-sil, including through corporate contributions to the Mir and K-Sports foundations. It also found that she had permitted confidential official documents to reach Choi. These findings concerned misuse of public authority and breaches of official obligations, not merely the presence of an unofficial adviser. (isearch.ccourt.go.kr) Applying the gravity standard, the Court held that the constitutional benefit of removal outweighed the institutional loss caused by ending her presidency. (english.ccourt.go.kr)

In 2024Hun-Na8, decided on April 4, 2025, the Court removed President Yoon Suk-yeol by a unanimous eight-justice decision following the Assembly’s December 14, 2024 impeachment. The case concerned his declaration of emergency martial law on December 3, 2024. (korea.net) The Court held that neither the substantive emergency conditions nor the procedural requirements for declaring martial law had been satisfied. It found that military and police deployments obstructed the Assembly’s constitutional authority, that the martial-law proclamation unlawfully prohibited legislative and political-party activity, and that military operations at the National Election Commission violated warrant requirements and institutional independence. The Court also held that the declaration remained subject to judicial review despite its highly political character, and that its rapid termination did not erase the grounds for impeachment. It assessed these violations as sufficiently grave to justify removal. This was a constitutional judgment terminating tenure, not a criminal conviction: the Court permitted constitutional recharacterization of unchanged underlying facts, while impeachment adjudication left separate criminal liability unresolved. (english.ccourt.go.kr)

Other Constitutional Removal Arrangements

In India, Article 61 of the Constitution permits impeachment of the president for violation of the Constitution, with either house of Parliament initiating the charge. A resolution proposing the charge requires at least fourteen days’ written notice, signed by no fewer than one-quarter of the initiating house’s total membership. Adoption requires at least two-thirds of that house’s total membership—not merely two-thirds of those present and voting. The other house then investigates the charge, or causes it to be investigated; the president has the right to appear and to be represented during the investigation. If the investigating house sustains the charge by a resolution supported by at least two-thirds of its total membership, the president is removed from the date that resolution passes. The houses therefore have interchangeable accusing and investigating roles, rather than permanently assigned functions. (legislative.gov.in)

India’s judicial-removal provisions use a different constitutional formulation. Article 124(4) provides for removal of a Supreme Court judge by presidential order following an address from each parliamentary house, presented in the same session, on grounds of proved misbehaviour or incapacity. Each address requires both a majority of the house’s total membership and at least two-thirds of members present and voting. Article 124(5) authorizes Parliament to regulate the investigation, proof, and presentation of the address; Article 218 extends these provisions to High Court judges. Although judicial removal is frequently described as impeachment, these provisions prescribe removal through parliamentary addresses and a presidential order, rather than Article 61’s expressly designated presidential impeachment procedure. (eparlib.sansad.in)

In France, Article 68, revised by the constitutional law of February 23, 2007, authorizes presidential removal for a breach of duties manifestly incompatible with continued exercise of the mandate. Parliament makes the removal decision sitting as the High Court (Haute Cour). Either parliamentary house may adopt a proposal to convene it; the proposal must immediately go to the other house, which has fifteen days to decide. The High Court is chaired by the president of the National Assembly and must decide on removal within one month, by secret ballot. Each house’s decision to convene the High Court and the High Court’s removal decision require two-thirds of the respective body’s entire membership. Proxy voting is prohibited, and removal takes immediate effect. (legifrance.gouv.fr)

Despite its name, the French High Court is not an ordinary criminal tribunal. In decision 2014-703 DC of November 19, 2014, the Constitutional Council characterized it as a parliamentary assembly empowered to remove the president, not a court adjudicating criminal offences committed in presidential office. Its decision concerns the continuation of the mandate rather than the imposition of a criminal sentence. This distinction separates Article 68’s constitutional accountability mechanism from proceedings under criminal law. (legifrance.gouv.fr)

In South Africa, Section 89 of the 1996 Constitution allows the National Assembly to remove the president with support from at least two-thirds of its members, but only for a serious violation of the Constitution or law, serious misconduct, or inability to perform official functions. Removal on either of the first two grounds also bars receipt of presidential benefits and service in any public office; those consequences are not prescribed for incapacity. Section 102 establishes a separate confidence mechanism requiring a majority of all Assembly members. A successful no-confidence motion against the president requires the president, the other Cabinet members, and deputy ministers to resign; one against the Cabinet excluding the president requires the president to reconstitute it. Unlike Section 89, Section 102 does not require one of the enumerated misconduct or incapacity grounds. South African Parliament consequently distinguishes these procedures even though presidential removal under Section 89 is commonly called impeachment. (justice.gov.za)

Judicial Review and Limits of Institutional Authority

In Nixon v. United States, 506 U.S. 224, decided on January 13, 1993, the United States Supreme Court held that a challenge to the Senate’s method of conducting an impeachment trial presented a nonjusticiable political question. The claimant was Walter Nixon, a federal district judge in Mississippi, not President Richard Nixon. Following his criminal conviction for false statements before a grand jury, Walter Nixon was impeached and removed in 1989. Under Senate Rule XI, a twelve-member committee received evidence and reported it to the full Senate, which made the final decision. Nixon argued that the constitutional requirement to “try” impeachments required the entire Senate to hear the evidence directly. The Court declined to adjudicate that challenge. (senate.gov)

Chief Justice William Rehnquist’s majority opinion emphasized the Constitution’s assignment of the “sole Power” to try impeachments to the Senate and the absence of a sufficiently precise, judicially manageable standard for interpreting “try.” It also connected nonreviewability to separation of powers: impeachment checks the judiciary, while judicial reconsideration of Senate judgments could undermine that check and the finality of removal decisions. Although all nine justices agreed on the judgment, their reasoning differed. Justice Byron White, joined by Justice Harry Blackmun, considered the issue reviewable but found the committee procedure constitutional; Justice David Souter accepted nonjusticiability in this case while reserving the possibility of review in extraordinary circumstances. Those reservations were concurring views, not exceptions adopted by the majority. (tile.loc.gov)

The allocation differs fundamentally in South Korea, where the Constitutional Court is the impeachment adjudicator rather than an external court reviewing a completed legislative trial. Following the National Assembly’s adoption of an impeachment motion, the chair of its Legislation and Judiciary Committee submits the case and acts as impeachment prosecutor. The Court conducts oral proceedings and determines whether removal is warranted; at least six justices must concur in a removal decision. Judicial participation therefore forms part of the constitutionally prescribed decision-making process, whereas the American arrangement restricts external judicial review of the Senate’s exercise of its trial power. (ccourt.go.kr)

Where judicial interpretation is limited, legislative precedents help give operational meaning to broad constitutional language. The House’s investigations, adopted articles, and decisions not to impeach provide evidence of how it has understood impeachable misconduct. The 1974 Judiciary Committee articles against Richard Nixon, for example, remain relevant to interpretation even though his resignation prevented a full House impeachment vote. Such institutional precedents differ from binding judicial precedents: a committee recommendation is not a chamber’s judgment, and an acquittal does not necessarily establish agreement on a single constitutional rationale. Historical practice supplies guideposts without exhaustively defining the scope of impeachable conduct. (constitution.congress.gov)

Post-office jurisdiction illustrates this distinction. In 1876, the Senate accepted jurisdiction over former Secretary of War William Belknap, who had resigned before the House impeached him, but subsequently acquitted him. On February 9, 2021, it voted 56–44 that former President Donald Trump was subject to an impeachment trial for acts committed while president. These decisions establish Senate precedents rather than a universally accepted judicial resolution of former-official jurisdiction. The relationship between removal and disqualification likewise involves constitutional interpretation: Senate practice treats disqualification as an additional, discretionary judgment after conviction and has permitted it by a simple majority, including a 39–35 vote concerning Judge Robert Archbald in 1913. That practice does not itself resolve every question about whether disqualification can stand independently of removal or what voting threshold the constitutional text requires.
