Powell v. McCormack
The Supreme Court ruled that the House of Representatives acted unconstitutionally when it excluded Adam Clayton Powell, Jr. from the 90th Congress, because Powell met all three qualifications the Constitution requires for House membership.
The decision limits Congress to judging only the age, citizenship, and residency qualifications spelled out in the Constitution, meaning neither chamber can refuse to seat an elected member for other reasons without going through the tougher two-thirds vote required to expel someone already seated.
“the Constitution does not vest in the Congress a discretionary power to deny membership by a majority vote.”
The Court's central holding that the House cannot exclude a qualified elected member by simple majority vote.
How it got here: A federal trial court dismissed the suit for lack of jurisdiction; the D.C. Circuit affirmed on different grounds; the Supreme Court granted review.
The Case in Depth
What happened
Adam Clayton Powell, Jr. was re-elected in 1966 to represent New York's 18th Congressional District, but after a congressional investigation into alleged misuse of funds and other misconduct, the House voted to exclude him from the 90th Congress rather than seat him. Powell and several of his constituents sued House officials, arguing that Powell met the Constitution's standing qualifications for office and that excluding him anyway was unconstitutional.
The question before the Court
Could the House of Representatives refuse to seat a duly elected Congressman even though he met the Constitution's age, citizenship, and residency requirements?
The Court's answer
No — the Court ruled that the House had no power to exclude Powell because he had already been found to meet the Constitution's three qualifications for membership (age, citizenship, and residency), and the Constitution does not let either chamber add extra requirements on top of those. The Court traced the history of the qualifications clause and the separate, harder-to-use expulsion power, concluding that letting a bare majority exclude an otherwise-qualified elected member would effectively bypass the Constitution's deliberate choice to require a two-thirds vote for punishing or removing a seated member.
Because Powell indisputably met the standing qualifications, there was nothing left to send back for further fact-finding on that question. The Court did, however, send the case back to the lower courts to sort out what specific remedies, like back pay, Powell could still pursue against individual House employees.

Why it matters
The ruling protects voters' choice of their own representatives: a legislature cannot simply refuse to seat someone the public elected just because a majority disapproves of that person's conduct or character. It also clarifies that punishing a sitting member for misconduct requires the higher two-thirds vote for expulsion, not a simple majority vote to exclude, making it harder for a bare majority to remove someone the voters chose.
What changes now
The Court's ruling on the constitutional question was final, resolving that the House could not exclude a member who met the Constitution's standing qualifications. However, the case was sent back to the lower courts to work out what remedies, such as back pay, Powell could obtain against House employees like the Sergeant at Arms, since the Speech or Debate Clause barred any relief directly against the individual Congressmen who had voted to exclude him.
What this does not decide
The Court expressly did not decide what limits, if any, exist on Congress's power to expel or punish a member who has already been seated, nor whether courts could review a chamber's factual finding that a member failed to meet a standing qualification. It also left the specific back-pay remedy against House employees for the lower courts to resolve.
Concurrences and dissents
Concurrence — Justice Douglas
Justice Douglas joined the Court's opinion in full but wrote separately to emphasize the broader democratic principle at stake: that voters, not a legislative majority, should decide who represents them. He recounted the earlier attempt to exclude Senator-elect William Langer of North Dakota on similar grounds, endorsing the view that a chamber cannot add unlisted qualifications simply by claiming to 'judge' existing ones.
Dissent — Justice Stewart
“Powell's claim for salary may not be dead, but this case against all these respondents is truly moot.”Stewart's argument that the Court should have dismissed the case as moot rather than decide the constitutional questions.
Justice Stewart argued the case had become entirely moot once the 90th Congress ended and Powell was seated in the 91st Congress, so the Court should not have reached the constitutional merits at all. He viewed Powell's remaining salary claim as too incidental to keep the broader controversy alive, drawing on Alejandrino v. Quezon, and argued Powell had an adequate alternative remedy: a straightforward money claim in the Court of Claims that would not require deciding sweeping constitutional questions.
How the Court got there
The legal reasoning, step by step
- The Court first had to decide whether the dispute was moot — no longer a live legal fight — after Powell was later seated in the 91st Congress. It held that Powell's claim for the salary withheld during his exclusion kept the case alive, since a court could still grant a declaratory judgment about that claim even without ordering him reseated.
- The Court then addressed the Speech or Debate Clause, a constitutional protection shielding lawmakers from being sued over their legislative acts. It held that while this shield barred the suit against the individual Congressmen, it did not protect House employees like the Sergeant at Arms and Clerk who carried out the exclusion, so the case could proceed against them.
- The Court rejected the argument that the House's action, despite being called an 'exclusion,' should be treated as an 'expulsion' (which requires a two-thirds vote under Article I). Because Powell had never been seated, and the House itself had voted on the theory that only a majority was needed, the Court declined to recharacterize the vote after the fact.
- Turning to whether the dispute was a 'political question' the courts should stay out of, the Court examined Article I's grant of power to each chamber to 'be the Judge of the... Qualifications of its own Members.' Reviewing the constitutional debates and centuries of practice, it concluded this power was limited to judging the three qualifications expressly listed in the Constitution — age, citizenship, and residency — not a general license to exclude members for other reasons.
- Because interpreting the scope of that clause was itself an ordinary act of constitutional interpretation — the kind of task courts routinely perform — the Court held the dispute was not a non-justiciable political question but one federal courts could and should decide.
- Applying that reading of Article I to the case, the Court concluded that because Powell met all three constitutionally listed qualifications, the House had no power to keep him from taking his seat, regardless of the alleged misconduct that motivated the vote.
Doctrinal impact
Cases affected by this decision
Reaffirms Kilbourn v. Thompson (103 U.S. 168)
The Court relied on this 1881 case to hold that House employees, unlike members, can be sued over unconstitutional legislative action.
Reaffirms Baker v. Carr (369 U.S. 186)
The Court applied this case's framework for identifying non-justiciable political questions to hold this dispute was reviewable.
Distinguishes Alejandrino v. Quezon (271 U.S. 528)
The Court held this case did not require dismissing Powell's suit as moot because his pleadings, unlike Alejandrino's, adequately supported his salary claim.
