I’ll be able to follow only the first hour or so of today’s oral argument in the tariffs case. Will be looking to see whether conservative justices are troubled by SG Sauer’s position. Might tweet a bit here.

Chief pushes back on broad reading of Dames & Moore

KBJ confuses Nixon with Lincoln

Kavanaugh presses on which way Nixon tariff cuts

ACB presses SG Sauer on other instances in which “regulate importations” has covered tariffs.

Kagan: Any instance in which “regulate” confers taxing power? Sauer: We’re not arguing that. It confers tariff power.

Sauer: “regulate importations” confers tariff power Sotomayor: phrase is “regulate importations and exportations,” but you agree no power to impose tariffs on exports

Chief: Why doesn’t major-questions doctrine apply?

Sauer: Point of statute is to confer major powers to address major emergencies

Chief: Imposition of taxes on Americans has always been core power of Congress

Sauer: Tariffs are regulatory, not revenue-raising. Most effective if they lead to no imports and no revenue. [At war with Trump admin claims about revenue] Sotomayor: Why not then just bar imports?

Trump admin right now celebrates revenue raised by tariffs. https://x.com/WhiteHouse/statu...

ACB: Algonquin case referred to license fee, not tariff. What’s significance of that?

Sauer: Difficult to see a distinction between a license fee on imports and a tariff.

Thomas: Give us your argument against nondelegation. Sauer: Does not apply with same force in foreign context. President’s own inherent authority combined with Congress’s conferral.

Alito on Yoshida case: Some statements there cut against you. Did Congress rely on those statements in enacting IEEPA?

A bit scary to hear Sotomayor relying on grammatical parts of speech. https://www.nationalreview.com...

Kagan: Tariffs are exercise of taxing power, not foreign affairs. Hampton case applied nondelegation to tariffs.

Kagan: In Consumers Research case last year, we assumed that no ceiling on tax would lead to nondelegation problem. Sauer: It’s a regulatory tariff, not a tax. Wholly different context. Foreign affairs.

Kagan: Title 19 is full of constraints on tariffs. Why would any president ever look to Title 19 instead of blowing past them via IEEPA? Sauer: Emergency declaration is constraint, invites intensive oversight by Congress. Kagan: But you say emergency declaration is unreviewable.

Gorsuch: Could Congress delegate to president power to regulate commerce with foreign nations? Isn’t that the logic of your position?

Gorsuch: You’re saying that there is inherent authority in all foreign affairs, so why under your theory can’t Congress delegate it all?

Gorsuch: You’re now conceding that nondelegation has some role, even if president is entitled to deference? Sauer agrees. Gorsuch: Could president impose 50% tariff on auto parts to deal with climate change? Sauer: Yes

At risk of overreading things, I think that Chief, Gorsuch, and ACB (and three liberals) have signaled some concerns with Admin’s position.

Gorsuch: One-way ratchet increasing presidential power. Gorsuch: Are tariffs always foreign affairs? Sauer: Always foreign-facing, but if revenue-raising rather than regulatory they don’t raise same issues

Kavanaugh invokes major-questions doctrine. What did Congress have in mind in 1977 regarding Nixon tariffs?

Kavanaugh: Why did no previous presidents use IEEPA to impose tariffs? Sauer: Tariffs weren’t natural tools for those emergencies.

Sauer: Trump far more comfortable using tariffs as a tool. Kav: Algonquin case held that “adjust imports” did not allow tariffs. [Not sure I got this right.] Sauer: Tariffing is quintessential way of regulating imports.

[Gotta cut out now]

@EdWhelanEPPC Art I, Section 8, para 1 grants “Congress power to lay and collect taxes, duties, imposts abd excises,” whereas para 3 grants Congress power “to regulate commerce with foreign nations.” IEEPA delegates to president only regulation, not taxing authority.

@EdWhelanEPPC Justice Gorsuch came in hot.

@EdWhelanEPPC It's going to be a unanimous smack down of the tariffs.
