Supreme Court of the United States

The Supreme Court of the United States is portrayed as both a source of constitutional change and a gatekeeper that repeatedly left racial and procedural injustice intact. Its rulings helped dismantle legal barriers to interracial relationships and gave defendants a stronger means to contest discriminatory jury selection, but other decisions upheld judicial overrides of jury sentencing, curtailed review of capital cases, and accepted the execution of juveniles and people with intellectual disabilities. Across these examples, constitutional protection appears not as a steady progression but as a contested field in which formal guarantees could coexist with entrenched exclusion.

Constitutional Authority and Racial Hierarchy

In the aftermath of slavery, laws regulating interracial intimacy helped preserve racial hierarchy. The book traces how fears of interracial sex and marriage supported racial-integrity laws and the wider system of racial subordination. In Alabama, the convictions of Tony Pace and Mary Cox for violating those laws reached the Supreme Court of the United States. The Court unanimously upheld the restrictions and their prison sentences, relying on reasoning that echoed the doctrine of separate but equal and anticipated the language later associated with Plessy v. Ferguson. The ruling gave legal force to restrictions that other states adopted or maintained, including beyond the South.

That constitutional position endured for decades. Although the Court had rejected racial exclusion from jury service in Strauder v. West Virginia, its approval of Alabama’s interracial-sex and marriage restrictions remained in place until 1967, when Loving v. Virginia struck down anti-miscegenation statutes. The contrast is stark: the Court could recognize a constitutional wrong in one setting while sustaining a different form of racial control for generations. Even after Loving, Alabama’s constitution still prohibited interracial marriage in 1986, when Walter McMillian met Karen Kelly. The persistence of that provision shows how a landmark ruling could alter constitutional law without immediately erasing the state’s formal or social legacy of racial hierarchy.

Jury Selection and the Limits of Formal Equality

The Court’s record on jury selection likewise combines an early constitutional rule with prolonged failures of enforcement. Strauder v. West Virginia established that excluding Black people from jury service was unconstitutional, but the principle did not ensure representative juries. In 1945, the Court upheld a Texas statute limiting the number of Black jurors to one per case. In the Deep South, jury rolls drawn from voting lists excluded many African Americans; after the Voting Rights Act, local practices and requirements such as being deemed intelligent and upright could still be used to keep jury pools largely white.

Later decisions addressed underrepresentation in jury pools, but the Court distinguished being summoned from actually serving: the Constitution barred exclusion based on race or gender without requiring that racial minorities or women sit on juries. Peremptory strikes, which prosecutors could use at their discretion, therefore remained a powerful means of removing Black prospective jurors. A mid-1960s ruling prohibited racially discriminatory use of those strikes, yet the evidentiary standard was so demanding that no challenge succeeded for twenty years. In counties that were 40 or 50 percent Black, defendants could still face all-white juries, especially in capital cases.

Batson v. Kentucky, decided in 1986, changed the terms of that challenge by allowing defendants to question prosecutors more directly about racially discriminatory strikes. The ruling gave Black defendants renewed hope, but the account also stresses its limits: prosecutors were pushed to find more creative ways to exclude Black jurors. Walter McMillian encountered this history while awaiting trial, hearing accounts from men on death row whose prosecutors had struck all or nearly all Black prospective jurors. The doctrine opened a route to contest discrimination; it did not by itself transform the jury room.

Capital Punishment and Restricted Review

In the book’s account of capital punishment, the Court’s decisions narrowed avenues for relief even as execution cases demanded careful scrutiny. By the late 1980s, federal habeas review had become more restrictive: claims not first presented in state courts could be barred, new evidence could be excluded if it had not been presented there, and federal judges were directed to defer more to state-court rulings. These changes gave procedural finality greater weight and made it harder for prisoners to obtain review of errors in capital proceedings.

The Court also upheld judicial override in an earlier Florida case, permitting a judge to impose death even when a jury had chosen against it. That ruling left Walter McMillian’s lawyers without a constitutional basis to stop Michael Lindsey’s execution on the ground that the jury had voted to spare his life. The governor denied their clemency request, and Lindsey was electrocuted on May 26, 1989. The episode exposes the practical consequence of the Court’s approval: a jury’s decision could be displaced, while the defendant’s constitutional challenge to that displacement had no available path forward.

Other rulings of the period reinforced the same restrictive climate. In the 1980s, the Court rejected a constitutional challenge to executing juveniles, upheld the death penalty for people with intellectual disabilities, and found no constitutional violation in the extreme racial disparities documented across death-penalty jurisdictions in McCleskey v. Kemp. The account presents these decisions alongside cases such as that of Horace Dunkins, whose intellectual disability was documented at trial but whose execution proceeded before the Court later prohibited the practice. The chronology makes the human cost of delayed constitutional protection plain: a later rule could recognize a violation while arriving too late for someone already executed.

Change, Delay, and Institutional Significance

The Court’s decisions did not move in a single direction. Loving v. Virginia repudiated an entrenched regime of racial regulation; Batson v. Kentucky made a previously ineffective challenge to jury discrimination more usable. Yet both rulings operated against structures capable of surviving formal doctrinal change. Alabama’s marriage ban remained in its constitution after Loving, and discriminatory strikes continued after Batson. In capital cases, meanwhile, procedural restrictions and decisions sustaining harsh punishments limited the ability of courts to correct injustice.

The book places this institutional record within a longer history in which racial terror, segregation, and punishment are connected rather than isolated. Its discussion of American racial history identifies slavery, the terror that followed Reconstruction, and the transformation of lynching’s violence into modern capital punishment as forces that shaped the country’s approach to race and justice. Against that background, the Supreme Court of the United States is not simply a distant source of doctrine. Its rulings determine which claims can be heard, which exclusions can be challenged, and whether a constitutional principle arrives in time to protect the person before the court. Its significance lies in that double capacity: it can dismantle a legal barrier, but it can also preserve the procedural conditions under which injustice continues.
