As the Supreme Court prepares to issue rulings on some of the most consequential constitutional questions in decades—including birthright citizenship, voting rights, and presidential powers—NPR's Throughline has revisited the institutional evolution that transformed the judiciary from the weakest branch of government into what critics and supporters alike now recognize as a powerhouse arbiter of American law.
The episode, published June 18, 2026, arrives as the justices make their final sprint toward the end of the 2025-26 term in early July. The Court's docket this term has been punctuated by high-stakes cases involving fundamental questions of executive authority, electoral integrity, and civil rights—with some of the most anticipated and significant decisions yet to be announced.
The Historical Evolution
The Throughline episode, which originally aired six years ago in 2020, examines how the Supreme Court claimed its current level of authority over constitutional interpretation. The program features insights from Larry Kramer, former dean of Stanford Law School and author of The People Themselves: Popular Constitutionalism and Judicial Review; Rachel Shelden, associate professor of History and director of the George and Ann Richards Civil War Era Center at Penn State University, and author of The Political Supreme Court; and Lucas Powe Jr., professor of Law and Government at the University of Texas.
The timing of the episode's republication underscores ongoing debates about the proper scope of judicial power, particularly as the Court confronts cases that will determine the boundaries of executive action and the constitutional framework governing citizenship and voting.
Constitutional Questions at Stake
The 2025-26 term has placed the Court at the center of disputes that will shape the relationship between individual rights, state sovereignty, and federal power. Cases involving birthright citizenship touch on fundamental questions of who qualifies for constitutional protections and whether executive or legislative branches can redefine longstanding interpretations. Voting rights cases similarly test the balance between state authority to regulate elections and federal oversight mechanisms.
Presidential powers cases before the Court will establish precedents for executive authority that could endure for generations, determining how much discretion future presidents possess in areas ranging from immigration enforcement to emergency powers. The consequential civil rights cases on the docket will clarify the extent to which government can regulate private conduct and speech.
The episode's examination of judicial evolution provides historical context for understanding how nine unelected justices came to wield such significant influence over questions that directly affect governance, economic policy, and individual liberty. The scholarly perspectives offered by Kramer, Shelden, and Powe trace the Court's transformation through critical periods in American history when the balance of power between branches shifted.
Why This Matters:
The Supreme Court's current term presents fundamental questions about constitutional governance that will affect the separation of powers, federalism, and individual rights for decades. Understanding how the Court accumulated its authority to serve as final arbiter on these questions is essential for citizens evaluating whether judicial supremacy serves the constitutional order envisioned by the framers. The cases pending decision will establish precedents governing executive power, state sovereignty over elections, and the scope of citizenship rights—all areas where judicial restraint versus judicial activism remains hotly contested. As unelected justices prepare to issue binding interpretations on matters affecting millions of Americans, the historical trajectory of judicial power gains renewed relevance for those concerned about democratic accountability and the proper limits of each branch of government.
