Impeachment
Federalist PapersImpeachment is a constitutional process for investigating and judging public officers accused of abusing or violating public trust. In the proposed system, the House of Representatives initiates the proceeding and the Senate tries it; this division is meant to make public accountability possible without allowing the same body to accuse and judge, or a faction to turn prosecution into unchecked persecution.
Purpose and Political Character
The offenses subject to impeachment arise from misconduct by public officials and concern injuries to society itself. They are therefore political in character, and their prosecution is likely to stir public passions and divide the community into supporters and opponents of the accused. Existing factions may bring their animosities, preferences, influence, and interests into the case. The danger is that judgment will then reflect the relative strength of the parties rather than the evidence of guilt or innocence.
Impeachment is consequently described as a national inquiry into the conduct of public men. Its purpose is not simply to resolve a private dispute, but to scrutinize the use of public authority and hold its holders answerable for breaches of trust. Because the proceeding concerns both the reputation and political standing of officials and the interests of the public, the tribunal must be able to withstand pressure from the accused’s allies as well as from those demanding conviction.
Division Between House and Senate
The proposed arrangement gives the House of Representatives the sole power to institute impeachments and assigns the Senate the role of deciding them. The division follows the model of Great Britain, where the House of Commons brings an impeachment and the House of Lords judges it; several state constitutions have also adopted the practice. The arrangement treats impeachment as a legislative restraint on executive servants, while separating accusation from judgment.
This separation of functions is offered as a safeguard against factional abuse. If either legislative branch became dominated by a hostile faction, it would not alone possess both the power to accuse and the authority to convict. In the Senate, conviction requires the concurrence of two-thirds, an additional protection against condemning an official through a narrow or inflamed majority. The procedure thus combines investigation by elected representatives with a more demanding threshold for judgment.
The Senate as Tribunal and the Objections to It
The Senate is defended as a suitable depositary of the trial because impeachment cases are politically charged and require a tribunal capable of preserving impartiality. In a government based on periodic elections, prominent officials may themselves become leaders or instruments of the largest or most skillful factions. The argument therefore doubts that ordinary political prominence alone guarantees neutrality and asks what body could be sufficiently dignified and independent to judge between an accused official and the people’s representatives who prosecute.
One objection holds that placing the trial in the Senate improperly mixes legislative and judicial authority. The response is that a limited intermixture for a special purpose can coexist with the general separation of departments. Just as an executive negative can check legislative encroachment, impeachment gives the legislature a means to check executive misconduct. The House’s role as accuser and the Senate’s role as judge prevent the same persons from performing both functions, while the two-thirds conviction requirement offers added security against persecution.
The comparison with New York’s constitution sharpens this reply. That constitution makes the Senate, together with the chancellor and Supreme Court judges, a court of impeachments and the state’s highest tribunal in civil and criminal causes. Since the judges are few in comparison with the senators, the argument says that New York’s ultimate judicial authority may fairly be said to reside in its Senate. Critics who accept that arrangement while condemning the proposed federal one are thus challenged to explain the difference.
Checks Within the Constitutional Structure
A further objection is that impeachment, combined with the Senate’s participation in treaties and appointments, would give that body excessive or aristocratic influence. The answer resists judging institutional balance through an undefined estimate of whether the Senate has too much power. Instead, it points to counterweights assigned to the House: the exclusive privilege of originating money bills, the sole right to institute impeachments, and the authority to decide a presidential election when no candidate receives a majority of the electoral votes. The House’s contingent role in choosing the president could, the argument suggests, become a particularly important source of influence.
Impeachment is also situated within the proposed Constitution’s broader account of lawful authority. The national legislature may make laws necessary and proper for carrying its assigned powers into execution, and the Constitution, laws made pursuant to it, and treaties made under its authority are declared the supreme law. But that supremacy is limited to measures made pursuant to constitutional powers: an act that invades powers left to the states is an usurpation, not valid supreme law. In the same way, impeachment is presented as a defined instrument of accountability within constitutional limits, not as permission for political branches to act without restraint.
The argument’s account of judicial independence further clarifies this institutional setting. Courts are described as the weakest department and therefore in need of permanence and protection from the other branches. In a limited Constitution, courts must be able to treat legislative acts contrary to the Constitution as void, or constitutional restrictions would have no practical force. Impeachment addresses a different problem—misconduct by public officers—but belongs to the same architecture of divided authority, in which each public power is bounded and the means of enforcement are assigned to particular institutions.
