Unwritten Law

In this episode of Unwritten Law, NCLA Senior Litigation Counsel John Vecchione and NCLA President Mark Chenoweth are joined by Andy Morris to discuss the Supreme Court’s 6–3 decision rejecting the claim that the President has unilateral authority to impose, raise, or lower tariffs under the International Emergency Economic Powers Act (IEEPA).
The conversation unpacks Chief Justice Roberts’s majority opinion, which relies on careful textual analysis to reaffirm that tariff authority belongs to Congress—not the Executive. John, Mark, and Andy explain why the statute’s language does not authorize revenue-raising measures, how the Constitution’s prohibition on export taxes reinforces that conclusion, and why decades of practice confirm that “regulating importation” does not mean imposing tariffs.
They also examine the dissents, including Justice Kavanaugh’s reliance on prior cases like Algonquin, the role of the Major Questions Doctrine, and why emergency powers do not justify bypassing Congress’s exclusive taxing authority. The episode closes with a broader discussion of separation of powers, the dangers of discretionary tariff regimes, and why this decision represents a major win for constitutional limits on executive power.

In this episode of Unwritten Law, NCLA Senior Litigation Counsel John Vecchione is joined by NCLA Senior Litigation Counsel Kara Rollins to discuss Sriptech v. SEC, a securities law case scheduled to be argued before the U.S. Supreme Court in April.
The case asks a critical question: must the Securities and Exchange Commission prove that investors suffered actual financial harm in order to obtain disgorgement in a civil enforcement action? John and Kara explain how recent Supreme Court decisions, including Kokesh and Liu, narrowed the SEC’s disgorgement authority while leaving this issue unresolved.

In this episode of Unwritten Law, NCLA President Mark Chenoweth and Senior Litigation Counsel John Vecchione mark the ten-year anniversary of what’s often called the Supreme Court’s “emergency docket”—sometimes labeled the “shadow docket”—and examine how it has reshaped constitutional litigation.
Mark and John explain what the emergency docket is, how it differs from merits decisions, and why its modern form is often traced to the Supreme Court’s 2016 decision to stay the Obama Administration’s Clean Power Plan. They discuss why emergency relief can be critical to preventing irreversible “fait accompli” outcomes when executive action races ahead of judicial review.
The conversation also explores debates sparked by critics of the emergency docket, the confusion it can create for lower courts, and whether decisions issued without full opinions should bind judges below. Along the way, Mark and John reflect on the legacy of Justice Antonin Scalia—whose final vote played a key role in the Clean Power Plan stay—and how his jurisprudence continues to influence debates over judicial power, originalism, and the proper limits of the administrative state.

In this episode of Unwritten Law, NCLA President Mark Chenoweth and Senior Litigation Counsel John Vecchione are joined by Russ Ryan to discuss a recent oral argument before the U.S. Court of Appeals for the Sixth Circuit challenging the federal government’s student loan payment and interest pause.
The case, Mackinac Center for Public Policy v. U.S. Department of Education, focuses on the executive branch’s decision—under both the Trump and Biden administrations—to extend a moratorium on student loan payments and interest accrual long after Congress’s limited authorization expired. Russ explains why those unilateral extensions wiped away billions of dollars in interest without statutory authority.
The discussion zeroes in on standing: how nonprofit public-interest employers benefit from Congress’s Public Service Loan Forgiveness program, why administrative action that reduces outstanding student debt can unlawfully diminish that congressionally granted subsidy, and how Supreme Court precedent—most notably Clinton v. City of New York—supports the theory that loss of a subsidy is a concrete injury.
Mark, John, and Russ also unpack the judges’ questions at oral argument, the Sixth Circuit’s prior rulings, and why this case could clarify when organizations may challenge executive actions that override Congress’s spending decisions.

In this episode of Unwritten Law, Mark Chenoweth and John Vecchione are joined by NCLA Of Counsel Margot Cleveland to discuss one of NCLA’s most consequential ongoing cases: Davidson v. Adkins, a constitutional challenge to the SEC’s Consolidated Audit Trail (CAT).
The CAT requires broker-dealers to collect and transmit detailed data on virtually every stock trade in the United States, creating a massive government-accessible database of Americans’ financial activity. Margot explains why recent changes announced by the SEC—such as removing names but retaining identifying numbers—do not cure the Fourth Amendment problem, and why suspicionless, warrantless searches of stock-trading data resemble the general warrants the Constitution was designed to forbid.
The episode also examines the SEC’s repeated requests for delays while the program continues to operate, the lack of congressional authorization or appropriation for CAT, related rulings from the Eleventh Circuit, and the broader dangers of mass financial surveillance for privacy, free association, and constitutional limits on agency power.
