In short, originalist research strongly supports the view that the president's art. II powers, whatever they might be with respect to diplomacy and national security, tell us nothing about the scope of his purely delegated power to impose tax imports. /END

Instead, founding-era presidents continued to defer to Congress in regulating foreign commerce, including in the imposition of embargoes, even when national security was directly implicated by US efforts to stay out of European wars and/or protect US shipping. 9/

In particular, while presidents claimed the power to set policy internationally & for the executive branch, they did not claim to be able to implement their policy choices as a matter of domestic law--the power that the govt seeks in VOS Selections/Oregon/Learning Resources. 8/

We walk through the drafting of the Constitution as well, but to keep a long thread short, the Founding Generation's practices in the early years reflected the British experience and the plain reading of the text of the Constitution. 7/

The Crown could not implement portions of international agreements, including peace treaties, that required trade and tariff concessions w/o parliamentary consent--a fact directly responsive to the govt's argument that POTUS's negotiations require interpreting his authorities broadly 6/

a few examples: The Framers wrote the Constitution against the backdrop of British law in which the tariff power belonged to Parliament. A chief complaint re: Charles I contributing to his ultimate execution was that he taxed, including specifically by imposing tariffs, w/o parliamentary consent. 5/

As the case moves to SCOTUS, a key issue will be what the justices make of the overlap between the president's general FA powers and Congress's FA powers. Our research suggests that the government's argument lacks a basis in originalist sources. Read the article for our whole analysis, but . . . 4/

As we explained in an earlier article, the Fed Cir. largely accepted these claims during litigation over the first Trump admin's tariffs under Section 232. But sitting en banc, it rejected the govt's foreign affairs framing in VOS Selections as applied to IEEPA. 3/ papers.ssrn.com/sol3/papers....

One of the gov't's central claims in the ongoing tariff litigation is that the president has independent Art. II power over foreign affairs, *and* that tariffs are a matter of foreign affairs, and thus the courts should interpret IEEPA differently than they would interpret other delegations. 2/

My new article w/ Kathleen Claussen, The Foreign Commerce Power, is now up on SSRN & forthcoming in @califlrev.bsky.social. We examine the relationship b/w Congress's foreign commerce/tariff authorities & POTUS's foreign affairs powers through an originalist lens. 1/ papers.ssrn.com/sol3/papers....

This Article is the first to scrutinize presidential trade authority under the Constitution. The Constitution grants the president no independent power to regul

The foreign interest point would apply to the tariffs too. There is surely a class of potential plaintiffs who are US companies importing goods they own and that no foreign person has an interest in.

The CIT op leaned more heavily on the states’ brief for that reason, I think. I think there is also a little disjunction re MQD/ND with the SC-focused lawyers wanting to make that the main issue & lower court judges wanting to look at it as a statutory interpretation question w/ MQD as icing.
timlmeyer.bsky.social
CAFC tariff argument focusing on what interpreting "regulate" to include tax power would do to other statutes. It would also expand the tax power in IEEPA beyond tariffs! Regulate modifies use, transfer, holding, acquisition-gov't argument means IEEPA authorizes sales taxes, property taxes, etc!

NEW from me in a Journal of International Economic Law symposium:

Towards a post-Trump order for the climate crisis.

I lay out why, despite setbacks, industrial policy is still the way to address climate change - and how macro and distributional policy can help.

The result is less transparent, stable, and accountable than legislation or ordinary administrative law. We wrote the article before the election last year, but from EOs on tariffs, FCPA, & TikTok Trump 2.0 is accelerating the trend toward presidential regulation dramatically.

Delighted that Presidential Regulation (w/ @ganeshsitaraman.bsky.social) has been published @ YaleJReg. We argue that presidents increasingly use presidential & foreign affairs powers to regulate the domestic economy in ways that aim to minimize judicial review. /1 www.yalejreg.com/wp-content/u...

Yesterday, the U.S. Court of International Trade ruled Trump’s emergency tariffs illegal, potentially dealing a blow to his trade leverage and ongoing negotiations with 18 countries.

TIMOTHY MEYER @timlmeyer.bsky.social breaks down the legal limits of presidential tariff power.
verfassungsblog.de
Since taking office, President Trump has imposed – or threatened – a steady stream of tariffs on almost any country that catches his attention.

TIMOTHY MEYER (@timlmeyer.bsky.social) argues that Trump does not have the power to impose most of his tariffs.

@lawfaremedia.org, Kathleen Claussen and I discuss a new front in the Trump Administration's efforts to evade meaningful judicial review of its actions: an attempt to expand the "foreign affairs" exception to the Administrative Procedure Act:

The Trump Admin’s Attempt to Redefine a ‘Foreign Affairs Function’
Courts will likely reject this effort to shield all of the executive’s cross-border actions from Administrative Procedure Act review.

In March, Secretary of State Marco Rubio published a notice which purports to regulate economic activity through national security and foreign affairs authorities. Kathleen Claussen and @timlmeyer.bsky.social explore the legality of the notice under the Administrative Procedures Act.

Looking forward to this Friday's colloquium, which puts @aratojulian.bsky.social in conversation w/ @timlmeyer.bsky.social to see how trade & investment treaties can make commitments sufficiently credible w/o overcoming the state’s ability to regulate in the public interest.

Thanks, I'll look forward to reading it! Ours is coming out in JREG too (which I think I forgot to mention but should have).

We will be revising the piece in light of the current administration’s action before publication later this year and welcome comments on it. /End.

We think President Trump’s expansive claims of foreign affairs powers over the domestic economy—clearly in evidence during the Biden and first Trump administrations but expanding in frequency and scope now—make plain that a paradigm shift is underway. 9/
