political question doctrine

The political question doctrine is a principle of justiciability grounded in the separation of powers. It limits the federal courts’ authority to decide certain constitutional questions that are committed to the political branches or that lack judicially manageable standards. In Baker v. Carr, 369 U.S. 186, 217 (1962), the U.S. Supreme Court articulated six considerations that may indicate the presence of a nonjusticiable political question:

  • A “textually demonstrable constitutional commitment” of the issue to a coordinate political department;
    • In this particular context, “political department” refers to one of the coordinate branches of the federal government; the legislative or executive branch, to which the U.S. Constitution delegated authority. The term does not refer to a governmental agency or other department.
  • The absence of clear and workable legal standards that courts can apply to resolve the issue;
  • It is impossible for the court to decide the issue without first making a policy decision that the Constitution leaves to the elected branches of government;
  • The court cannot decide the issue without interfering with the role of another branch of government;
  • The courts are expected to accept a political decision that has already been made; and
  • Different parts of the government could reach conflicting decisions about the same issue, creating confusion.

The presence of any one of these characteristics may render a claim nonjusticiable. However, the Court has emphasized that the political-question doctrine does not apply merely because an issue concerns “politics” or has significant political consequences. 

Examples of Nonjusticiable Political Questions:

Partisan Gerrymandering. 

In Rucho v. Common Cause, 588 U.S. 684 (2019), the Supreme Court held that claims alleging unconstitutional partisan gerrymandering present nonjusticiable political questions. Writing for the Court, Chief Justice Roberts relied in significant part on the second factor presented in Baker: whether judicially discoverable and manageable standards exist for resolving the claim. The Court drew on Justice Kennedy’s concurrence in Vieth v. Jubelirer, 541 U.S. 267 (2004), which explained that any judicial standard for evaluating partisan gerrymandering must rest on a “limited and precise rationale” and be “clear, manageable, and politically neutral.” The Court concluded that no such standard existed for determining when partisan gerrymandering becomes constitutionally excessive. The claims depended on competing definitions of political fairness, including different views concerning proportional representation, competitive districts, and the appropriate allocation of political power. Because the Constitution provides no judicially discernible standard for choosing among these competing conceptions of fairness, the Court concluded that federal courts lack the authority to resolve partisan-gerrymandering claims.

Senate Impeachment Trial Procedures. 

In Nixon v. United States, 506 U.S. 224 (1993), the U.S. Supreme Court held that a former federal district judge’s challenge to the Senate’s impeachment procedures presented a nonjusticiable political question. In this case, Walter Nixon challenged a Senate rule that permitted a committee to receive evidence and report its findings to the full Senate rather than requiring the entire Senate to hear the evidence directly. The Court considered the first and second factors in Baker, but placed particular emphasis on the U.S. Constitution’s textual commitment of impeachment trials to the Senate. Article I, § 3, cl. 6 provides that “[t]he Senate shall have the sole Power to try all Impeachments.” The Court viewed the word “sole” as significant because it indicated that the authority to try impeachments belongs exclusively to the Senate.

The Impeachment Trial Clause also imposes several express requirements: senators must act under oath or affirmation, conviction requires the concurrence of two-thirds of the members present, and the Chief Justice is the presiding officer when the President is tried. Nixon argued that the word “try” implicitly required the Senate’s proceedings to conform to judicial-trial procedures and therefore prohibited the Senate from delegating the evidentiary function to a committee. The Court rejected that argument, reasoning that the specific requirements expressly included in the Clause suggested that the Framers did not intend to impose additional procedural limitations based solely on the use of the word “try.” The Court further concluded that judicial review of the Senate’s impeachment trial procedures would create a significant risk of judicial interference with a power that the U.S. Constitution had expressly delegated to the Senate. Because the Constitution committed the impeachment-trial function to the Senate, and provided no judicially manageable standard for determining how the Senate must conduct those proceedings, the Court held that Nixon’s challenge presented a nonjusticiable political question.
