Key Takeaways
- Nixon v. United States (1993) established that the Senate has exclusive authority to determine its own impeachment trial procedures, and such decisions are political questions not subject to judicial review.
- The ruling reinforced the separation of powers by making clear that the judiciary cannot intervene in the Senate’s constitutional role to try impeachments, thus limiting the courts’ ability to oversee or invalidate congressional impeachment processes.
- This case is distinct from United States v. Nixon (1974), which addressed executive privilege and presidential accountability, but both cases collectively illustrate the Supreme Court’s approach to maintaining the balance of power among the branches of government.
Introduction
Nixon v. United States, 506 U.S. 224 (1993), stands as a foundational Supreme Court decision concerning the constitutional boundaries of impeachment procedures. The case arose from the impeachment of Walter Nixon, a federal district court judge, who was convicted of committing perjury before a grand jury. After his conviction and refusal to resign, the House of Representatives impeached him, and the Senate subsequently convicted and removed him from office. Nixon challenged the process by which the Senate conducted his impeachment trial, specifically objecting to Senate Rule XI, which allowed a committee to gather evidence and present findings to the full Senate rather than requiring the entire Senate to hear all evidence directly.
The Supreme Court’s decision in this case clarified that the Constitution grants the Senate the "sole Power to try all Impeachments" (Article I, Section 3, Clause 6), and that the judiciary has no authority to review or dictate the Senate’s impeachment procedures. This ruling has had a lasting impact on the interpretation of the separation of powers and the concept of nonjusticiable political questions.

Background of Nixon v. United States
Walter Nixon’s Impeachment
Walter L. Nixon, Jr. served as the Chief Judge of the United States District Court for the Southern District of Mississippi. In the 1980s, Nixon became embroiled in a scandal involving perjury before a federal grand jury. After a criminal conviction and subsequent imprisonment, Nixon refused to step down from his lifetime judicial appointment. The House of Representatives, exercising its constitutional authority, impeached Nixon in 1989 on grounds of perjury and bringing disrepute to the judiciary.
Senate Impeachment Trial and Rule XI
The United States Senate, following its own rules, invoked Senate Rule XI, which permitted a committee of Senators to receive evidence and testimony, and then report their findings to the full Senate. The full Senate would then review the evidence and vote on whether to convict and remove the impeached official. Nixon objected to this process, asserting that the Constitution required the entire Senate to participate directly in all aspects of the trial, including hearing live testimony.
Nixon’s challenge was predicated on the belief that the Senate’s use of a committee deprived him of a constitutionally required trial by the full Senate. He argued that this process violated the Impeachment Trial Clause of the Constitution.
Legal Issues Presented
The Impeachment Trial Clause
Article I, Section 3, Clause 6 of the United States Constitution provides:
"The Senate shall have the sole Power to try all Impeachments. When sitting for that Purpose, they shall be on Oath or Affirmation. When the President of the United States is tried, the Chief Justice shall preside: And no Person shall be convicted without the Concurrence of two thirds of the Members present."
The central question in Nixon v. United States was whether the judiciary could review the Senate’s procedures for conducting impeachment trials, or whether this power was exclusively vested in the Senate.
Political Question Doctrine
The political question doctrine is a principle in constitutional law that holds certain issues are not justiciable by the courts because they are constitutionally committed to another branch of government. Nixon’s challenge required the Supreme Court to determine whether the Senate’s impeachment procedures were subject to judicial review, or whether they were a political question outside the judiciary’s competence.
Supreme Court’s Decision
Majority Opinion
Chief Justice William Rehnquist delivered the opinion of the Court. The Supreme Court held, by a 9–0 vote, that the question of whether the Senate had properly tried an impeachment was a nonjusticiable political question. The Court’s reasoning was grounded in the text, structure, and history of the Constitution.
The majority opinion emphasized that the word “sole” in the Impeachment Trial Clause granted the Senate exclusive authority over impeachment trials. The Court stated:
“The word ‘sole’ appears only once in the Constitution with respect to the allocation of power, and it is used to describe the Senate’s role in trying impeachments.”
Therefore, the judiciary could not review the Senate’s interpretation or application of its own rules for impeachment trials.
Concurring Opinions
Justice Stevens, joined by Justices White and Souter, wrote a concurring opinion emphasizing that even if judicial review were theoretically available, the Senate’s procedures in Nixon’s case were reasonable and consistent with constitutional requirements.
Justice White, joined by Justice Blackmun, wrote separately to stress that there might be circumstances where Senate action would be so egregious as to warrant judicial intervention, but that was not the case here.
Justice Souter, concurring in the judgment, also noted that not every conceivable Senate action would be immune from judicial review, but agreed that Nixon’s challenge did not present such an extreme case.

Implications of the Ruling
Separation of Powers
The ruling in Nixon v. United States reinforced the separation of powers by making clear that the Constitution assigns the impeachment trial function exclusively to the Senate. The judiciary is not authorized to second-guess or intervene in the Senate’s procedures, even if those procedures are challenged as unfair or insufficient.
This decision preserves the independence and integrity of Congress’s role in impeachment, preventing the courts from becoming entangled in inherently political disputes. It also reflects the Framers’ intent to keep the impeachment process outside the reach of the judiciary, recognizing the political nature of impeachment and the need for finality in removal decisions.
Limits of Judicial Review
By holding that the Senate’s impeachment procedures are a nonjusticiable political question, the Supreme Court set a clear limit on judicial review in this context. The courts cannot review, overturn, or dictate the Senate’s rules or methods for trying impeachments. This stands in contrast to other areas of constitutional law where the judiciary is empowered to interpret and enforce constitutional provisions.
Impact on Future Impeachments
The Nixon v. United States decision has had a lasting influence on the conduct of federal impeachments. The Senate retains broad discretion to determine how it will conduct impeachment trials, including the use of committees or other procedural mechanisms. This precedent has been cited in subsequent impeachment proceedings, including those involving federal judges and presidents, to justify the Senate’s authority to structure its own process.
Comparison with United States v. Nixon (1974)
Overview of United States v. Nixon
It is important to distinguish Nixon v. United States (1993) from United States v. Nixon (1974), as both cases involve individuals named Nixon but address entirely different constitutional questions.
United States v. Nixon, 418 U.S. 683 (1974), arose from the Watergate scandal. President Richard Nixon attempted to withhold tape recordings and documents subpoenaed by a federal district court, citing executive privilege. The Supreme Court unanimously held that the President was not above the law and must comply with the judicial subpoena.

Differences in Legal Questions
- Nixon v. United States (1993): Concerned the Senate’s authority and the nonjusticiability of impeachment procedures.
- United States v. Nixon (1974): Concerned the limits of executive privilege and the President’s obligation to comply with judicial orders.
Significance in Separation of Powers
Both cases illustrate the Supreme Court’s approach to the separation of powers. In Nixon v. United States, the Court deferred to Congress’s exclusive authority over impeachment, refusing to intervene. In United States v. Nixon, the Court asserted its authority over the executive branch, requiring the President to comply with the rule of law.
These cases demonstrate the judiciary’s dual role: respecting the constitutional prerogatives of the other branches while ensuring that no branch exceeds its constitutional authority.
The Political Question Doctrine in Detail
Origins and Application
The political question doctrine is rooted in the idea that certain constitutional questions are committed to the discretion of the political branches of government and are not suitable for judicial resolution. In Baker v. Carr, 369 U.S. 186 (1962), the Supreme Court articulated factors for identifying political questions, including:
- A “textually demonstrable constitutional commitment” of the issue to another branch;
- A lack of judicially discoverable and manageable standards for resolving the issue;
- The impossibility of deciding the issue without making a policy determination not suitable for judicial discretion.
Application in Nixon v. United States
The Supreme Court found that the Impeachment Trial Clause’s assignment of the “sole Power” to the Senate was a clear textual commitment. The Court also noted the absence of judicially manageable standards for determining what constitutes a constitutionally adequate impeachment trial.
Thus, the Court concluded that the challenge to Senate procedures was a classic political question, and the judiciary must abstain from involvement.
Practical Consequences for Impeachment Proceedings
Senate’s Flexibility in Impeachment Trials
Following Nixon v. United States, the Senate has continued to use committees and various procedural mechanisms in impeachment trials. The ruling provides the Senate with maximum flexibility to adapt its procedures to the circumstances of each case, whether the subject is a federal judge or the President.
Judicial Recourse for Impeached Officials
The decision forecloses judicial recourse for impeached officials who object to the Senate’s procedures. Once the Senate has rendered a judgment of conviction and removal, that decision is final and unreviewable by the courts. This ensures the finality and political accountability of the impeachment process.
Public and Scholarly Debate
The decision has generated debate among legal scholars and the public. Some argue that the absence of judicial review could allow the Senate to adopt unfair or arbitrary procedures. Others contend that the political nature of impeachment requires that it remain insulated from judicial interference to preserve the constitutional balance.
Broader Constitutional Context
The Role of Impeachment in the U.S. System
Impeachment is a critical constitutional mechanism for holding federal officials accountable for “Treason, Bribery, or other high Crimes and Misdemeanors.” The Constitution divides the impeachment power between the House of Representatives (which brings charges) and the Senate (which tries impeachments).
The Framers designed the process to be political rather than judicial, recognizing that removal from office is a political remedy, not a criminal punishment. The Supreme Court’s decision in Nixon v. United States reflects and reinforces this understanding.
Checks and Balances
The decision in Nixon v. United States is an example of the system of checks and balances at work. By refusing to intervene in Senate impeachment procedures, the judiciary respects Congress’s constitutional prerogatives. At the same time, the judiciary retains the power to check the other branches in other contexts, as shown in United States v. Nixon.

Conclusion
Nixon v. United States (1993) is a landmark Supreme Court decision that clarified the constitutional boundaries of the impeachment process in the United States. By holding that the Senate has exclusive authority to determine its own impeachment trial procedures, and that such matters are nonjusticiable political questions, the Court reinforced the separation of powers and preserved the independence of Congress in matters of impeachment.
This case, along with United States v. Nixon (1974), provides critical insights into the Supreme Court’s approach to the separation of powers and the limits of judicial review. Together, they underscore the importance of respecting the constitutional roles assigned to each branch of government.
