Release Date: July 13, 2025

Introduction

In this episode of The Lawfare Podcast, hosted by Benjamin Wittes of The Lawfare Institute, Mary Ford—a Lawfare intern—engages in a profound discussion centered around Julian Mortensen's groundbreaking work on the U.S. Constitution's executive power. The conversation delves into Mortensen's article, "Article 2 Vests Executive Power, Not the Royal Prerogative," challenging conventional interpretations of presidential authority.

Background and Genesis of Mortensen's Project

Mary Ford begins by tracing the origins of Mortensen's research. Originally tasked with reviewing John Yoo's work related to the George W. Bush administration, Mortensen stumbled upon a historical inconsistency regarding the President's ability to override statutes in matters of national security and foreign affairs.

"[05:34] Mary Ford: ...there wasn't a historical basis for the strong claim by the Bush administration that there are lots of circumstances where if a foreign affairs question or a national security question is sufficiently important, the President can simply ignore a statute..."

This realization propelled Mortensen into a seven-year investigative journey to reassess the meaning of "the executive power" as stipulated in Article II of the U.S. Constitution.

Mortensen's Main Thesis

Benjamin Wittes introduces Mortensen's central argument:

"[03:34] Benjamin Wittes: ...Julian Mortensen ... argues that this conventional understanding is wrong, wrong. Not a little bit wrong, not mostly wrong, but completely wrong as a matter of history..."

Mary Ford expounds that Mortensen contends "the executive power" should be interpreted not as residual royal prerogative powers inherited by the President but as a derivative authority strictly limited to executing laws enacted by Congress.

"[37:19] Mary Ford: ...the executive power is the power to execute. The executive power is the power in a governance context to execute the laws and projects of an exercise of the legislative power..."

Traditional Vesting Clause Thesis vs. Mortensen’s Argument

The traditional interpretation posits that the vesting clause in Article II grants the President all residual powers not explicitly denied by the Constitution, akin to the royal prerogative. This has been the foundation for expansive presidential authority in areas like foreign policy and national security.

Mary Ford critiques this view by asserting:

"[24:56] Mary Ford: It's about as wrong as it could be... I am completely confident that it's wrong."

Contrastingly, Mortensen argues that the vesting clause was intended to confer a specific, limited authority—the execution of laws—without inheriting the broad, discretionary powers of a monarch.

Implications of Mortensen’s Argument

This reinterpretation has profound implications for the balance of power between the Executive and Legislative branches:

1. Presidential Authority Limitation:

   • Torture and Interrogation: Without inherent prerogative powers, presidents cannot override statutes like torture bans.

     "[46:25] Benjamin Wittes: ...you should construe the War Powers Resolution narrowly ... that would violate the Constitution vis a vis the Executive Power Clause... [Mary Ford] ... you can't say the canon of constitutional avoidance... is gone."

2. Treaty Withdrawal:

   • NATO Withdrawal: Congress could potentially legislate to prevent the President from unilaterally withdrawing from treaties.

     "[45:54] Benjamin Wittes: ...Congress, assuming it, could pass over his veto a law that says the President may not withdraw from NATO could prevent the President from withdrawing from NATO."

3. Statutory Interpretation:

   • The executive power no longer serves as a constitutional shield for presidents to interpret or limit congressional statutes autonomously.

     "[49:39] Mary Ford: ...it wipes off the table any claim that ... the statutes ... should be construed narrowly because otherwise it would be unconstitutional..."

Real-World Examples Highlighting the Debate

Benjamin Wittes cites several instances where the traditional vesting clause thesis has been pivotal:

• San Andreas Fault of Executive-Legislative Tensions:

  "[17:37] Benjamin Wittes: ...that's the tectonic plates of a great deal of the controversy we have had over executive versus legislative authority over the last 15 years..."

• Supreme Court Cases:

  • The Steel Seizure Case remains unresolved, with no clear Supreme Court majority on the vesting clause's interpretation.

Reception and Pushback

Mary Ford acknowledges that Mortensen's conclusions have been met with resistance, particularly from ideological conservatives who traditionally support the vesting clause thesis. However, she notes an absence of detailed rebuttals, often categorizing feedback as supportive or awaiting further scholarly engagement.

"[51:46] Mary Ford: ...some of the resistance that I've encountered... this article doesn't talk... this article makes a claim about the standard, utterly uncontested meaning of a phrase."

Despite pushback, Mortensen remains confident in his thesis, anticipating that further research and analysis will substantiate his claims.

Conclusion

This episode of The Lawfare Podcast presents a critical examination of presidential powers through Julian Mortensen's scholarly work. By challenging the entrenched vesting clause thesis, Mortensen advocates for a constitutional interpretation that significantly limits executive authority, reinforcing Congressional supremacy in legislative governance. As national security and foreign policy debates continue to evolve, Mortensen's insights offer a pivotal framework for rebalancing the powers of the U.S. presidency.
