When the Supreme Court of the United States announced its decision in Ex parte McCardle on April 12, 1869, it did something it has almost never done before or since: it dismissed a case for want of jurisdiction that it had already taken, argued, and been expected to decide on the merits. The case involved William H. McCardle, a Mississippi newspaper editor held in military custody under the Reconstruction Acts, who had sought a writ of habeas corpus from the Circuit Court for the Southern District of Mississippi. When the circuit court refused to issue the writ, McCardle appealed to the Supreme Court under a statute Congress had passed in 1867, the Habeas Corpus Act of that year. The case was argued for four days in March 1868. Before the Court could issue its decision, Congress — controlled by the Radical Republicans, who feared the Court would declare the entire Reconstruction program unconstitutional — passed a rider to an unrelated appropriations bill, repealing the portion of the 1867 act that had granted the Court appellate jurisdiction in such cases. President Andrew Johnson vetoed the repeal; Congress overrode his veto. McCardle's lawyers moved to dismiss their own appeal, and the Court, in an opinion by Chief Justice Salmon P. Chase, granted the motion. The Court, Chase wrote, was “not at liberty to inquire into the motives of the legislature”; it could only examine the statute, and the statute had withdrawn jurisdiction. The case was dismissed. McCardle remained in military custody. The Reconstruction Acts were never reviewed by the Court in that posture, and the constitutional crisis that had been brewing since the end of the Civil War — between a president who had lost all legitimacy, a Congress that ruled by supermajority, and a Court whose legitimacy was equally in question — was defused by the astonishing spectacle of the judiciary surrendering its power to the legislature.

McCardle is a strange case to invoke in a series about taking America back. It is not an inspiring story of rights vindicated. It is a story of institutional hardball, of a Congress so convinced of the rightness of its cause and the danger of judicial obstruction that it was willing to reach into the Court's docket and pull a case out by the roots. It is also, however, a story that goes directly to the most contested structural question in American constitutional law: can Congress control the Supreme Court's jurisdiction to prevent the Court from destroying the constitutional order, and if it cannot, what recourse remains when the Court itself becomes the instrument of destruction? The Radical Republicans believed the answer to the first question was yes, and they acted on that belief. The Court's acquiescence in McCardle established a precedent that has been debated, limited, and feared for one hundred fifty-five years. In an age when the question is no longer theoretical — when scholars, senators, and citizens openly discuss court-packing, jurisdiction-stripping, and other forms of congressional response to a judiciary they believe has gone rogue — McCardle is the case that cannot be avoided. To understand it, you have to understand the constitutional moment that produced it, the men who fought it, and the terrifying gap in the constitutional design that it exposed: the Framers gave us no clear answer for what to do when the Court itself is the problem.

The Constitutional Crisis of 1868

The situation in 1868 was unlike anything before or since. The Civil War had ended in April 1865 with the Confederacy destroyed, slavery abolished by the Thirteenth Amendment, and the Union preserved. But peace had not brought settlement. Andrew Johnson, the Tennessee Democrat who had become president upon Lincoln's assassination, had spent three years waging a guerrilla war against Congress's Reconstruction program. He had vetoed the Civil Rights Act of 1866 and the Freedmen's Bureau bills; Congress had overridden him. He had opposed the Fourteenth Amendment, which Congress had proposed in June 1866 to secure citizenship and equal protection for the freedpeople; he had campaigned against it in the 1866 midterm elections and had been repudiated by voters, who delivered Congress to the Radical Republicans with supermajorities in both houses. He had opposed the Reconstruction Acts of 1867, which divided the South into five military districts, imposed martial law, and required new constitutions guaranteeing Black male suffrage as conditions for readmission to the Union. Congress had passed those acts over his vetoes too. By 1868, Johnson was a president without a party, without a mandate, and without legitimacy — impeached by the House in February of that year for violating the Tenure of Office Act, and awaiting trial in the Senate. He would survive by one vote, but his political power was finished.

The Radical Republicans in Congress — men like Thaddeus Stevens in the House and Charles Sumner in the Senate — were not merely implementing a policy. They were attempting a constitutional revolution. They believed, with the abolitionist tradition behind them and the blood of six hundred thousand dead fresh in memory, that the Union victory had settled not merely the question of secession but the question of national citizenship. The Fourteenth Amendment was their instrument: it declared that all persons born or naturalized in the United States were citizens, that no state could abridge the privileges or immunities of citizens, deprive any person of life, liberty, or property without due process, or deny equal protection of the laws. To make that amendment real in the South required military occupation, because the former Confederate states, restored to civil government under Johnson's lenient reconstruction, had immediately enacted the Black Codes — vagrancy laws, apprenticeship laws, anti-enticement statutes — that reduced freedpeople to a status of peonage barely distinguishable from slavery. The Reconstruction Acts were Congress's response: martial law to enforce the new constitutional order until the states could be reconstructed on loyal and republican foundations.

The Supreme Court was the graveyard threat. The Court of 1868 was the Court of Dred Scott v. Sandford (1857), the decision that had declared African Americans not citizens and Congress powerless to prohibit slavery in the territories — a decision so morally and constitutionally bankrupt that it had helped precipitate the war. Chief Justice Roger Taney was dead (1864), but his successor, Salmon P. Chase, was a former antislavery politician whose instincts were judicially conservative in a different register: Chase had presided over the Court's 1866 decision in Ex parte Milligan, which held that trial of civilians by military commission was unconstitutional where the civil courts were open. Milligan had been decided just before the Reconstruction Acts were passed, and it hung over the entire program like a thunderhead. If Milligan applied to the South — if the military commissions trying civilians under the Reconstruction Acts were unconstitutional — then the entire edifice of congressional reconstruction could collapse in a single opinion. The Radicals had reason to fear exactly that. Meanwhile, a separate case, Ex parte Yerger, involving another Mississippi newspaper editor held by the military, was working its way toward the Court on a parallel track, raising the same questions about the constitutionality of military commissions under the Reconstruction Acts. The Radicals were hearing from their own lawyers that the Court was ready to strike.

McCardle: The Case, the Rider, the Surrender

William H. McCardle was not a sympathetic petitioner. He was the editor of the Vicksburg Times, a fiery secessionist and white supremacist who had used his paper to denounce military rule, denounce Black suffrage, and advocate resistance — rhetoric that the district commander, General Edward O.C. Ord, considered incendiary and dangerous. Arrested in November 1867 and charged with impeding reconstruction, libel, and disturbing the peace, McCardle sought habeas corpus in federal court, arguing that his arrest and trial by military commission violated the Constitution. When the circuit court denied the writ, he appealed to the Supreme Court under the 1867 Habeas Corpus Act, a statute Congress had passed to expand federal judicial protection for prisoners — and which, ironically, the Radicals had intended primarily to protect freedpeople and Unionists, not ex-Confederate editors. The Court granted review and heard argument in March 1868. McCardle's counsel, including the prominent Democratic lawyer Jeremiah Black, argued that the military trial was unconstitutional under Milligan. The government, represented by Attorney General William Evarts, defended the Reconstruction Acts as valid exercises of Congress's war powers — or, in the alternative, its power to guarantee republican forms of government under Article IV, Section 4.

The Radicals in Congress did not wait for the decision. On March 12, 1868, while the case was under submission, the House passed a rider to a minor bill repealing the section of the 1867 act that had authorized the appeal. The Senate followed on March 20. Johnson vetoed the bill; Congress overrode the veto on March 27. The repeal was deliberately targeted and deliberately cynical: it left the 1867 act's expansion of habeas corpus in place for future cases but stripped the Court's appellate jurisdiction over cases already pending under that section. McCardle's lawyers, recognizing the game, filed a motion to dismiss their own appeal rather than have a decision rendered that might produce a precedent against military reconstruction in other forms. The Court's opinion by Chase was, in substance, a capitulation dressed in the language of duty. The Court, he wrote, had no choice: “Without jurisdiction the court cannot proceed at all in any cause. Jurisdiction is power to declare the law, and when it ceases to exist, the only function remaining to the court is that of announcing the fact and dismissing the cause.” The repeal, Chase continued, was within Congress's power under the Exceptions Clause of Article III — which grants the Supreme Court appellate jurisdiction “with such exceptions, and under such regulations as the Congress shall make” — and the Court would not inquire into the legislature's motives.

The opinion was unanimous. It was also, in its effect, a declaration that Congress could, by manipulating jurisdiction, insulate its most controversial policies from judicial review. The Radicals had won. Reconstruction proceeded without a judicial declaration of unconstitutionality. McCardle himself was soon released; the military commission was dissolved when Mississippi was readmitted to the Union in 1870. But the precedent was set: the Court had accepted that its appellate jurisdiction was subject to congressional control, even in cases already argued and awaiting decision, even when the congressional motive was transparently to prevent a constitutional ruling. The case became, in the language of the law reviews, the “jurisdiction-stripping” precedent, and it has been the rock on which every subsequent debate about congressional checks on judicial power has foundered.

The Counterfactual: What the Court Might Have Done

To grasp what the Radicals feared, it is necessary to imagine the decision they prevented. Had the McCardle case gone to judgment, the most probable outcome — based on the Court's composition, its reasoning in Milligan, and the arguments pressed by Jeremiah Black at the bar — was a declaration that the military trial of civilians under the Reconstruction Acts was unconstitutional. The legal logic would have been straightforward Milligan extension: the civil courts were open in Mississippi by 1867; therefore the military commission lacked jurisdiction; therefore McCardle's detention was unlawful; therefore — the unstated but inevitable consequence — the entire apparatus of military reconstruction was void. Every military commission operating in the five districts would have been dissolved. Freedman's Bureau arrests, voter-registration drives conducted under military supervision, and the provisional governments themselves might have been challenged as fruits of unconstitutional authority. The fragile constitutional order that was registering Black voters across the South could have been dismantled by a single opinion from a Court whose members had been appointed, in substantial part, by prewar and wartime administrations with little sympathy for Radical Reconstruction.

The counterfactual is not speculation about judicial motives; it is an assessment of what the Court's doctrine, publicly stated in Milligan, logically entailed. The Radical Republicans' lawyers told them as much. Their decision to strip jurisdiction was not a cynical power grab against an innocent judiciary — it was a defensive maneuver against an announced doctrinal threat. That distinction matters for the contemporary debate. The legitimacy of using the Exceptions Clause depends on whether the threat being defended against is constitutional or partisan. In 1868, the threat was constitutional in the deepest sense: the Fourteenth Amendment's survival. Whether a future jurisdictional confrontation could claim the same moral architecture is the question every proponent of court-curbing must answer under oath to history.

The Exceptions Clause and Its Discontents

Article III, Section 2, Clause 2 of the Constitution provides that the Supreme Court shall have appellate jurisdiction “both as to law and fact, with such exceptions, and under such regulations as the Congress shall make.” The plain meaning of the text suggests broad congressional power. The historical record is more ambiguous. The Exceptions Clause was inserted at the Philadelphia Convention in response to arguments about the scope of federal judicial power, but the debates reveal no consensus on its intended breadth. Madison's notes record little discussion of the clause. The Federalist Papers are almost silent. In Marbury v. Madison (1803), Marshall treated the grant of original jurisdiction in Section 13 of the Judiciary Act of 1789 as unconstitutional, but he did so by construing the statute and the Constitution together, not by questioning Congress's power over appellate jurisdiction. The first major test came in Martin v. Hunter's Lessee (1816), where the Court upheld Congress's power to provide for Supreme Court review of state court judgments, and in Cohens v. Virginia (1821), where Marshall wrote in dicta that Congress's power over appellate jurisdiction was “subject to the control of the legislature.”

McCardle pushed that dictum to its extreme. The Radicals' argument, made in the congressional debates and accepted by the Court, was that the Exceptions Clause gave Congress plenary power to define the Court's appellate docket. The counter-argument, which has been developed by generations of constitutional scholars — most prominently Henry Hart, in his famous 1953 Harvard Law Review dialogue “The Power of Congress to Limit the Jurisdiction of Federal Courts” — is that the power must have limits. Hart argued that Congress could not use jurisdiction-stripping to “destroy the essential role of the Supreme Court in the constitutional plan.” The essential functions, he suggested, included maintaining the supremacy and uniformity of federal law and protecting constitutional rights against state violation. A Congress that stripped jurisdiction to prevent the Court from performing those functions would be acting unconstitutionally, even if the literal text of Article III seemed to permit it. The McCardle Court had said it would not inquire into motives, but Hart and his successors have argued that motive matters when the effect is to subvert the constitutional structure.

The Court has never definitively resolved the question. In United States v. Klein (1872), decided just three years after McCardle, the Court struck down a statute that attempted to prescribe rules of decision in pending cases by directing the Court how to treat presidential pardons as evidence — a distinction between jurisdiction and rules of decision that has proven elusive. In Robertson v. Seattle Audubon Society (1992), the Court upheld a statute that changed the law applicable to pending cases without changing the jurisdictional statute, holding that Congress could legislate around pending litigation so long as it did not direct the judiciary's decision. In Bank Markazi v. Peterson (2016), the Court upheld a statute that made specific assets available to satisfy judgments in a specific pending case, over a dissent that argued the law was a legislative adjudication. The line between permissible regulation and unconstitutional interference has been drawn and redrawn, but McCardle's core holding — that Congress can strip appellate jurisdiction over a pending case — remains nominally intact, though largely untested in its most dangerous form.

Why McCardle Matters Now

The relevance to the present moment is not subtle. The constitutional order faces a legitimacy crisis in the judiciary unlike any since 1868. A Supreme Court whose composition has been shaped by norm-breaking — a seat held open for a year by one party, confirmed by the other in the final weeks of a presidential term, then filled by a third justice under a cloud of credible misconduct allegations — has issued decisions that have dismantled precedent, expanded executive power, and restricted voting rights, reproductive freedom, and environmental regulation, often in ways that align with partisan political outcomes. Public confidence in the Court has collapsed to historic lows. Scholars and politicians have responded with proposals that would have been unthinkable a generation ago: expanding the number of justices (court-packing), imposing term limits, creating a code of ethics with enforcement mechanisms, and — most radically — stripping the Court of jurisdiction over specific categories of cases. The jurisdiction-stripping proposals draw directly on McCardle. They are advocated by legal scholars who argue that the Exceptions Clause means what it says, and that Congress has the power to prevent the Court from deciding cases involving abortion, guns, affirmative action, or any other subject where its rulings are deemed destructive of constitutional democracy.

The Radical Republicans faced a version of this dilemma. They believed — with considerable justification — that the Supreme Court of 1868 was a threat to the most important constitutional project since the founding itself: the transformation of the United States from a slaveholder's republic into a multiracial democracy. They believed that the Court would use the Constitution's own text to declare Congress's enforcement of the Constitution unconstitutional. Their response was to use the Constitution's own text — the Exceptions Clause — to prevent the Court from speaking. The question for us is whether that response was a heroic defense of constitutionalism or a dangerous precedent that normalized the legislative subversion of judicial independence. The answer, as with so many things in American constitutional history, is that it was both.

The Founders' Silence and the Structural Gap

The Framers gave us no good answer. They designed a system of separated powers with checks and balances, but they did not design a check for the judiciary itself. Hamilton, in Federalist No. 78, called the judiciary “the least dangerous branch” because it had “no influence over either the sword or the purse” and “can take no active resolution whatever.” It had “neither FORCE nor WILL, but merely judgment.” That was the theory. The practice, as McCardle demonstrated, is that judgment can be the most dangerous power of all, because it operates through the legitimation of law. A Court that declares the enforcement of constitutional rights unconstitutional can do more damage than an army, because it disarms the constitutional system itself.

Madison, in Federalist No. 51, wrote that “ambition must be made to counteract ambition.” But what happens when the ambitions of the political branches are aligned — as the Radical Republicans' ambitions were — and the judiciary's ambition is to defeat them? The Framers assumed that the judiciary would be checked by the political branches through impeachment, through control of jurisdiction, and through the appointment power. Impeachment of judges had been used in the Jeffersonian era — against Justice Samuel Chase in 1804-1805 — and had failed in the Senate, establishing a norm that impeachment was for criminal misconduct, not for judicial philosophy. The appointment power requires vacancies, which come slowly and unpredictably. Jurisdiction remained, and McCardle tested whether it could be used as Madison's architecture implied: as a counterweight to judicial overreach. The Court's acceptance of the check suggested that the architecture worked. But the check itself was so blunt, so destructive of judicial independence as a principle, that it has never been used again in the same way. The gap remains: if a future Court declares, in a pending case, that Congress's fundamental legislation is unconstitutional — if it strikes down the Voting Rights Act's remaining provisions, or the Affordable Care Act, or environmental regulations on a scale that makes governance impossible — does Congress have the power to strip jurisdiction and prevent the ruling? McCardle says yes. Hart says maybe not. The current Court has never been asked to decide.

What the Radicals Got Right — and What They Risked

The Radical Republicans were not constitutional vandals. They were constitutional faithful, defending the Fourteenth Amendment against a judiciary they believed would betray it. They understood, as the Founders did, that parchment barriers are not self-enforcing; they must be defended by political action. The jurisdiction-stripping rider of 1868 was an ugly, dangerous, necessary act of constitutional self-defense. It preserved Reconstruction for a decade, allowed the ratification of the Fifteenth Amendment, and enabled the freedpeople to vote, hold office, and participate in American politics for the first time. The cost was a precedent that has been available ever since to any Congress seeking to shield its handiwork from judicial review. The Radical Republicans were willing to pay that cost because the alternative — judicial nullification of Reconstruction — was, in their judgment, worse.

The question for our generation is whether we face a comparable crisis, and if so, whether we are willing to use the same tools. The answer cannot be found in the Constitution's text, because the text is ambiguous. It cannot be found in precedent, because McCardle stands alone in its extremity. It can only be found in a judgment about whether the judiciary has become what Hamilton feared it could not be: the most dangerous branch, not because it wields the sword or the purse, but because it wields the law itself as a weapon against the constitutional order. If that judgment is made, McCardle is the case that tells us what Congress can do. The harder question is what Congress should do — and whether any legislative check on judicial power can be used to save the Constitution without, in the act of saving it, destroying the judicial independence that makes the Constitution worth saving.
