Trump tariffs face a judicial reality check
A recent decision by the U.S. Court of International Trade held that President Trump exceeded his authority under the International Emergency Economic Powers Act by imposing sweeping tariffs, ruling the measures unconstitutional and enjoining their enforcement--setting the stage for ongoing appellate battles that could ultimately reach the Supreme Court.






In one of the cases and courts I discussed in my essay entitled "Trump's
tariff strategy tests the limits of presidential power and legal
authority," Daily Journal, May 6, 2025, the United States Court of International
Trade (CIT) has reached a decision. In Oregon et al. v. Trump, the court
found that Trump exceeded his authority in issuing the tariffs in question.
Further, the court ordered that the tariffs be vacated
and their operations permanently enjoined. Specially, the three-judge panel
unanimously found that:
"The
Constitution assigns Congress the exclusive powers to 'lay and collect Taxes,
Duties, Imposts and Excises,' and to 'regulate Commerce with foreign Nations.'"
U.S. Const. art. I, § 8, cls. 1, 3. The question in the two cases before the
court is whether the International Emergency Economic Powers Act of 1977
(IEEPA) delegates these powers to the President in the form of authority to
impose unlimited tariffs on goods from nearly every country in the world. The
court does not read IEEPA to confer such unbounded authority and sets aside the
challenged tariffs imposed thereunder.
Overview of the case
On May 28, 2025, the CIT ruled on two consolidated cases
involving challenges to tariffs imposed by the President under the
International Emergency Economic Powers Act (IEEPA). The plaintiffs included
both private companies (V.O.S. Selections, Inc. v. Trump, Case No.
25-00066; referred to by the court as the V.O.S Plaintiffs), and several U.S.
states (State of Oregon v. Trump, Case No. 25-00077; referred to by the
court as the States Plaintiffs), who argued that the tariffs exceeded the
President's authority under IEEPA. See Slip Opinions 2025, number 25-66
at https://www.cit.uscourts.gov/content/slip-opinions-2025.
Legal background
The court examined
the constitutional allocation of tariff powers to Congress and the statutory
framework of IEEPA. It noted that IEEPA does not grant the President unlimited
authority to impose tariffs, as such authority would conflict with the Constitution's
separation of powers. The court emphasized that IEEPA's powers are limited to
addressing "unusual and extraordinary threats" with a declared national
emergency.
Factual background
Since taking
office, Trump quickly began declaring national emergencies and imposing tariffs
on goods from Canada, Mexico, and China, citing drug trafficking and trade
imbalances as justification. The tariffs included a 25% duty on Canadian and
Mexican products and a 20% duty on Chinese products. Additionally, a general
10% duty was imposed on imports from all trading partners, with higher rates
for specific countries.
Procedural background
The V.O.S.
Plaintiffs and State Plaintiffs filed lawsuits challenging the tariffs, arguing
they were beyond the President's authority under IEEPA. The court granted
summary judgment in favor of the plaintiffs, finding no genuine dispute of
material fact.
Jurisdiction and standing
The court
asserted its exclusive jurisdiction under 28 U.S.C. § 1581(i) to hear cases
involving tariffs and duties. It found that both the V.O.S. Plaintiffs and
State Plaintiffs had standing, as they demonstrated economic harm from the
tariffs.
Court's analysis
The court concluded
that IEEPA does not authorize the Worldwide and Retaliatory Tariffs because
they lack identifiable limits and do not address an "unusual and extraordinary
threat." The court also found that the trafficking tariffs did not "deal with"
the threats they purported to address, as required by IEEPA.
Conclusion
The court held that the
tariffs exceeded the President's authority under IEEPA and were therefore
unlawful as a matter of law. It vacated the challenged tariff orders and
permanently enjoined their operation. The court granted the plaintiffs' motions
for summary judgment and denied their motions for preliminary injunction as
moot.
Now we must wait and see
how the U.S. District Court for the Northern District of California rules on
similar facts and law in California v. Trump. On May 20, 2025, the U.S.
District Court of the Northern District of Florida, although siding with Trump
on the merits, stating as its basis the 50-year-old case of Yoshida
International v. U.S., sustaining President Nixon's 10% duty imposing a 10%
duty under the Trading With the Enemy Act, the IEEPA's predecessor; Presiding
Judge T. Kent Wetherell nonetheless transferred the case (Emily Ley Paper
Inc. d/b/a Simplied v. Donald J. Trump, ND Fla #3:25-00464) to the CIT. See
Dkt . Nos. 5 and 37, at https://ecf.flnd.uscourts.gov/cgi-bin/DktRpt.pl?838619638445753-L_1_0-1
But wait, the Trump empire strikes back! Temporarily
On May 29, 2025, the Court of Appeals for the Federal Circuit
issued an order granting the motion by Defendant-Applicants Trump, et al,
allowing the president to continue collecting tariffs under the IEEPA while the
appeal is prosecuted. Here's the docket entry filed by the court:
"ORDER
filed. The motions to consolidate appeals [1092676-2]; [1092675-2] filed by
Defendant-Appellants are granted. The requests for an immediate stay
[1092776-2]; [1092779-2] are granted to the extent that the judgments and the
permanent injunctions entered by the Court of International Trade in these
cases are temporarily stayed. The parties are directed to immediately inform
this court of any action taken by the Court of International Trade. Plaintiffs-Appellees'
response to the motion to stay due 6/5/25. Reply due 6/9/25. The revised
official caption is reflected in the order. See the order for full and
complete details. By: En Banc (Per Curiam). Service as of this date by the
Clerk of Court. [1092896] [25-1812, 25-1813]" See, Dkt. Nos. 4, 6 and 7,
at https://ecf.cafc.uscourts.gov/n/beam/servlet/TransportRoom?servlet=CaseSummary.jsp&incOrigDkt=Y&incDktEntries=Y&caseNum=25-1813.
So, the next pivotal date will likely be sometime in June or
maybe later when the Court of Appeals makes its ruling on the merits. But then
again, no matter which side losses, it will likely appeal to SCOTUS.
