• Sarah’s new book, Last Branch Standing, is available for pre-order – praised as an accessible, inside look at the Supreme Court.

2. Setting the Stage: Who’s Who and Procedural Context [04:58–06:53]

• Amy Howe: Renowned SCOTUS reporter, onsite at the courthouse.
• David Latt: Author of “Original Jurisdiction,” legal industry newsletter.
• Roman Martinez: Veteran SCOTUS litigator, wrote an amicus brief supporting the tariff challengers.

3. Supreme Court Handicapping: Predicting the Outcome

Guest Predictions & Judicial Dynamics [06:53–14:20]

• Roman Martinez [06:53]:

  • “Not going to be unanimous…both sides are going to have at least, probably at least three votes and then there are probably three votes in the middle that are up for grabs.”
  • Chief Justice Roberts, Justice Barrett, and Justice Gorsuch viewed as swing votes; Kavanaugh appeared more sympathetic to the government.

• David Latt [11:06]:

  • Predicts a win for the tariff challengers: “Gorsuch, along with Justices Alito and Thomas, sort of forms this right wing of the Court. He was going at Sauer. I think he’s going to switch places…a 6:3 lineup with the dissenters being Justices Thomas, Alito and Kavanaugh.”

• Sarah Isgur [13:21] summarizes core questions for the court:

  1. Did Congress give the President tariff power?
  2. Can Congress give the President such power (non-delegation)?
  3. Did the President meet the statute’s requirements?
     The oral argument focused more on statutory and constitutional questions, less on emergency parameters.

• David French [14:20]:

  • Senses momentum shifted back-and-forth: Gorsuch “staked out some very, very clear ground that I think is just very tough for the pro tariff position.”

Notable Quote

“Am I wrong? A key part of the context is the constitutional assignment of the taxing power to Congress. The power to reach into the pockets of the American people is just different, and it has been different since the Founding.”
— Justice Gorsuch, recapped by David French [16:45]

4. Non-Delegation, Major Questions, and Judicial Philosophy [18:11–23:46]

• Sarah Isgur [18:11, 26:52]: Discusses Barrett versus Gorsuch approaches to major questions doctrine — Barrett sees it as a textual aid, Gorsuch as a limitation even where the statute is ambiguous.
• Roman Martinez [19:42]:
  • “Major questions doctrine is a way of interpreting a statute, and the non-delegation doctrine is a constitutional argument... they’re really getting at the same idea, which is problems with Congress delegating too much authority.”
  • Raises "donut hole" problem — the power to ban imports but not levy tariffs.
  • Emphasizes difficulty securing a fifth vote among Roberts and Barrett.

5. Courtroom Dynamics: Justice Barrett as Swing Vote, On-the-Ground Reporting [25:15–30:38]

• Guests note Justice Barrett’s genuine, engaged questioning – focused, still forming a view, not posturing for colleagues.
• Amy Howe [28:14]: “You can sort of see the law professor in her… very, very focused… questions coming out in real time.”

6. Government’s Argument Under Pressure, Practical and Theoretical Concerns [30:48–39:41]

• Key tension: Government argued tariffs are “regulation” as required by statute, but also boasted about revenue (tax) effects [31:35].
• Sarah Isgur [32:54]: Notes the problem that, once such power is recognized, Congress cannot realistically reclaim it due to the veto structure (with a call-out to INS v. Chadha).
• David French [34:43]: Highlights the structural issue: “If there is a check on the President, where does the check come from? … In reality, no branch. That might be the right constitutional answer.”

7. Precedent, Hypotheticals, and Doctrinal Nuance [39:41–52:58]

• Amy Howe [40:14, 49:03]: Reports on Justice Alito’s hypotheticals—can a president, having the power to ban, also impose a 1% tariff?
• David Latt [50:07]: Suggests the Court could have a split result: possibly upholding some tariffs but not others to avoid a sweeping decision.
• All note political (not partisan) calculation may enter close, high-profile cases.

8. Major Questions Doctrine—Consistency Across Administrations [52:58–61:40]

• Sarah Isgur [52:58]: Compares current case to the Court’s application of the major questions doctrine in striking down major Biden-era executive actions.
• Roman Martinez [53:52]: Cautions against “simple” parallels—Court will strive for consistency, may distinguish case on foreign affairs/geopolitics.
• David Latt [60:19]: On “supreme politics”: “Sometimes it’s almost subconscious where the justices are almost making these sort of subconscious calculations of their relation to the other branches.”

9. Wider Term Context: Executive Power Cases [61:40–63:48]

• Three major cases this term on presidential power:
  1. Tariff Case (Trump/Emergency Powers)
  2. Rebecca Slaughter Case (Presidential Removal Power over Agencies)
  3. Case pending on the President’s authority over the Federal Reserve Board
• Amy Howe [58:38]: Emphasizes Supreme Court’s effort to delineate the lanes of Congress and the president—keeping each “on their side of the car” to preserve constitutional balance.
• David French [62:04]: Predicts a Court skeptical of executive overreach into Congressional authority, but likely supportive of executive control within the executive branch.

Notable Quotes & Memorable Moments

• On Justices’ Body Language [29:41]:

  • “She is… listening very attentively and very, very, very focused. And you can see that the question sort of coming out in real time as the oral argument progresses.” — Amy Howe on Justice Barrett

• On High Stakes and Uncertain Outcomes [63:48]:

  • “After hearing all of you talk about this, I’m even less sure of how this case will come out than I went in. I felt far more confident before I heard the oral arguments... Now I'm leaving, throwing my hands in the air.” — Sarah Isgur

• On Courtroom Realities [40:14]:

  • “Did the justices ever need bathroom breaks? Do they look like they're getting tired up there?” — Sarah Isgur
  • “I did not see anybody take a break… They get coffee delivered to them during the argument, and I genuinely don't know how they do it.” — Amy Howe

• On Gorsuch's Constitutional Framing [16:45]:

  • “The power to reach into the pockets of the American people is just different, and it has been different since the Founding.” — Justice Gorsuch (as recounted by David French)

• Meta-Legal Humor:

  • “We need someone who speaks the language of originalism as a mother tongue and not a second language.” — David French (paraphrasing Mike Huckabee) [15:36]

Overall Tone & Audience Takeaways

• The tone is collegial, thoughtful, occasionally playful (“Is this more like football analysis or figure skating analysis?”) and deeply nerdy—in the best sense.
• Panelists emphasize the unpredictability and complexity of Supreme Court dynamics, the importance of close reading and statutory nuance, and the evolving doctrines at the intersection of law and politics.
• Consistent throughline: the justices’ reasoning, not their partisan leanings, will likely determine the outcome, though institutional and subconscious dynamics play a role.

Final Thoughts

This episode is a must-listen for anyone interested in constitutional law, Supreme Court practice, and the future of executive power. The panel’s lively, informed analysis—punctuated by direct experience and on-the-ground reporting—offers a window into how the Court might grapple with one of the term’s most consequential cases.
