Last July, President Donald Trump imposed 50 percent tariffs on various Canadian goods, a list he subsequently expanded to include additional imports, some of which he banned outright. His legal justification was Section 338 of the Smoot-Hawley Tariff Act, which Congress approved in 1930. Section 338 authorized tariffs in response to discriminatory trade practices. But in the 96 years since it was enacted, no president had ever used it to impose tariffs.

Why is that? According to a lawsuit that the Liberty Justice Center (LJC) filed on Tuesday in the U.S. Court of International Trade (CIT), the answer is clear: Section 338 was superseded by subsequent legislation that likewise targeted discriminatory trade barriers, beginning with the Reciprocal Trade Agreements Act of 1934 and culminating in Section 301 of the Trade Act of 1974. Section 301, the current remedy, includes requirements that Trump apparently sought to dodge by invoking Section 338 instead.

That maneuver is illegal, the LJC argues. "Congress already gave the executive branch a tool for responding to unfair foreign trade practices: Section 301, which requires an investigation, public comment and other safeguards," says Jeffrey M. Schwab, the LJC's director of litigation. "The administration cannot skip those protections by reaching for a 1930 statute that no president had ever used to impose a tariff."

Why not? "Where provisions in two acts are in irreconcilable conflict, the later act, to the extent of the conflict, constitutes an implied repeal of the earlier one," the lawsuit says. "Where a later act covers the whole subject of an earlier one and is clearly intended as a substitute, it operates similarly as a repeal. And a specific policy embodied in a later federal statute controls the construction of an earlier one even absent express amendment."

Even if Section 338 somehow survived congressional approval of contrary laws, the LJC adds, Trump's tariffs exceed the authority it grants. And if Trump's interpretation of Section 338 were correct, the lawsuit says, the provision would violate the nondelegation doctrine, which bars Congress from delegating its tariff power to the president without providing "an intelligible principle" to guide and constrain his exercise of it.

Trump's Section 338 tariffs, in short, are "the Administration's latest attempt to exercise, through a statute never designed for the purpose, the tariff power that the Constitution assigns to Congress." That pattern should be familiar by now.

Shortly after taking office in 2025, Trump claimed to have discovered a previously unnoticed delegation of extensive tariff authority in the International Emergency Economic Powers Act (IEEPA), a 1977 law that does not mention import taxes and had never been used to impose them. That claim was rejected by every court that considered it, and last February the Supreme Court ruled that IEEPA does not authorize tariffs at all.

Trump responded to that decision by immediately announcing similarly broad tariffs under Section 122 of the 1974 Trade Act, which addresses "fundamental international payments problems" caused by "serious United States balance-of-payments deficits." In May, the CIT ruled that the new tariffs were illegal because Trump had failed to "identify balance-of-payments deficits within the meaning of Section 122."

Trump then switched to Plan C, invoking Section 301 of the Trade Act, which authorizes tariffs in response to a foreign "act, policy, or practice" that is "unreasonable or discriminatory" and "burdens or restricts" U.S. commerce. He claimed that provision justified tariffs on 86 trading partners, accounting for nearly all U.S. imports, because they had failed to "impose and effectively enforce a prohibition on the importation of goods produced with forced labor." The CIT is currently weighing challenges to those tariffs, including an LJC lawsuit.

Trump's Section 338 tariffs have now added to the CIT's caseload. The LJC represents Gellert Global Group, an importer that was hit hard by those taxes after Trump added cheese to the list of disfavored Canadian goods. The lawsuit asks the CIT to certify a class of importers, numbering in "the hundreds, if not the thousands," that likewise have been clobbered by Trump's 50 percent tariffs.

Since Trump obviously is aware of Section 301, why did he resort to a never-used, seemingly obsolete provision to justify the tariffs on imports from Canada? As the LJC notes, Section 301 requires an investigation by the Office of the U.S. Trade Representative, "consultation with the foreign country concerned, notice, public comment, a hearing, and determinations within statutory deadlines." It also requires "that action be equivalent in value to the burden imposed, that duties be preferred over other import restrictions, and that actions terminate after four years absent a request for continuation and review."

Can Trump avoid those constraints by invoking Section 338 instead? The LJC thinks not: "Congress did not intend to leave in place a parallel authority that would allow the President to impose the same remedies, for the same conduct, free of every one of those safeguards."

Section 338 has been "impliedly repealed," the LJC argues. "At a minimum, Section 301 controls where, as here, the President seeks to respond to foreign practices within Section 301's scope, and the President may not impose duties in response to such practices while disregarding the procedures and limits Section 301 imposes. Because the President did not proceed under Section 301, the Section 338 Tariffs are unlawful whether or not Section 338 survives."

Even if you ignore subsequent legislation, the LJC argues, the Canadian policies that Trump cited when he announced the tariffs do not qualify as "discrimination" under Section 338. "Canada's motor vehicle surtax and its provinces' alcohol purchasing decisions are responses to tariffs that the United States imposed on Canada, not discrimination by Canada against the United States," it says. Trump also complained that Canada treats European cheese imports more favorably than U.S. cheese imports. But "when Congress enacted Section 338, a preference granted under a reciprocal agreement was not 'discrimination.'"

Section 338 "addresses discrimination: measures that single out United States commerce for worse treatment than the commerce of the world at large," the lawsuit says. "It is not a general authorization to impose tariffs whenever the President disagrees with a trading partner's policies, or whenever a trading partner responds to tariffs the United States has imposed on it."

Trump also was unfazed by Section 338's requirement that the president set duties to "offset" the costs imposed by discriminatory practices, which implies proportionality. Rather than attempt that, the LJC notes, Trump imposed "the statutory maximum rate of 50 percent without tying it to any measured burden."

As interpreted by Trump, the lawsuit warns, Section 338 authorizes the president to "impose tariffs of up to 50 percent on any products of any country that extends better treatment to any other country in any respect—including through any of the hundreds of preferential trade agreements to which the United States is not a party—or that responds to tariffs the United States has imposed on it." Yet Section 338 "contains no clear statement authorizing that power," contrary to the "major questions" doctrine, which applies to assertions of executive authority with "vast economic and political significance."

If Section 338 conferred the sort of unfettered authority that Trump is claiming, the LJC says, it "would supply no intelligible principle constraining the exercise of Congress's power to lay duties." His reading "would convert a narrow, fact-dependent provision into an effectively unrestricted delegation of Congress's tariff power," which would be "an unconstitutional delegation of legislative power."

This case "is not about the president," says LJC CEO Sara Albrecht. "It is about the presidency. No president should have the power to pull a dormant statute off the shelf and use it to impose sweeping tariffs or import bans without the limits Congress required."

Today, the Liberty Justice Center (LJC) filed Gellert Global Group Corp. v. Trump, the first lawsuit challenging President Donald Trump's massive Section 338 tariffs against a variety of Canadian imports. The case was filed in the US Court of International Trade (which has jurisdiction over tariff-related cases); Gellert Global Group is an importer of Canadian cheese subject to the tariffs. LJC is the same public interest group that I worked with on the case challenging Trump's earlier IEEPA tariffs, which ultimate resulted in their invalidation by the Supreme Court. I am not directly involved in the present case. But I support it and believe it deserves to prevail.

LJC has also filed cases challenging Trump's massive Section 122 and Section 301 tariffs. They have become America's premier public interest law group standing up for free trade and enforcing constitutional constraints on executive power over trade restrictions.

Section 338 was part of the infamous Smoot-Hawley tariff act of 1930, which gravely exacerbated the Great Depression. It has never been used before, likely because it was superseded by later laws.

I have previously written about why Trump's Section 338 tariffs are harmful and illegal. See my recent Montreal Economic Institute paper on this topic, and earlier pieces here, here, and here. To briefly summarize, the tariffs on Canada are illegal because 1) Section 338 has been superseded by later legislation, 2) even if Section 338 is still operative, Trump's tariffs do not meet its requirements because the Canadian actions they supposedly respond to do not "discriminate" against US goods, as the law requires, 3) Trump's tariffs do not "offset" the Canadian actions (as Section 338 also requires), but go far beyond that, 4) the administration's interpretation of Section 338 runs afoul of the "major questions" doctrine, and 5) if Section 338 is operative and does authorize the Trump actions, it would violate the constitutional nondelegation doctrine (which restricts delegation of legislative power to the executive).

The LJC complaint advances all five of these arguments. To prevail, they need win on only one. They also add a few more technical points that I will not try to cover here. LJC further seeks a class action certification for a class of all those importers subject to the Section 338 tariffs. If this succeeds, it would block all enforcement of Section 338 tariffs, not just those paid by Gellert.

This lawsuit does not directly challenge Trump's extension of the Section 338 action to categorically ban some Canadian imports, in addition to imposing tariffs. As far as I can tell, Gellert does not import goods subject to the ban (as opposed to the tariffs). However, as I explained here and here, the legality of the bans is dependent on that of the initial tariffs. In a recent Lawfare article, I outline the reasons why executive-imposed import bans are subject to most of the same legal constraints as executive-imposed tariffs.

Like the IEEPA, Section 122, and Section 301 tariffs, Trump's use of Section 338 is an attempt to convert a limited delegation of authority into a blank check enabling the president to impose tariffs whenever he wants. Courts should reject all of these power grabs.

I commend LJC for bringing this important case. And I hope and expect it may not be the last lawsuit challenging the Section 338 measures. Future cases might well challenge the import bans directly, as well as the tariffs.

Georgetown law Professor Steve Vladeck is one of the leading critics of the conservative majority on the Supreme Court. But in an insightful recent post on his substack, he outlines key reasons why "court expansion" is a bad response to its flaws. The cure is likely to be worse than the disease:

[I]t seems to me that those who are fully onboard the expansion-or-bust train should have to do more than simply assert that having four new Democratic appointees on the Court in 2029 would be a self-evidently "good" thing. If nothing else, proponents of expansion should have to answer the following four questions:

1. How do we avoid touching off a race to the bottom, where each time one party controls the House, Senate, and presidency, it expands the Court to ensure an ideologically and politically sympathetic majority?
2. If a race to the bottom is unavoidable, how do we avoid further (and potentially fatal) erosion of public confidence in the Court—which will quite transparently be little more than a lever of power for whichever party last had such a trifecta?
3. If eroding public confidence in the Court is a feature, and not a bug, how do we insulate against the same erosion of public confidence in lower federal courts?
4. What is the case for why expansion is a better way to achieve the desired reforms than alternatives that would (or, at least, should) avoid many of these forward-looking concerns?

He adds that court-packing could easily "permanently undermine judicial review as an institution." The rest of his piece (which is behind a paywall) offers far from reassuring answers to these questions.

I have offered similar criticisms of court-packing in a long series of articles and blog posts, most recently in a June Lawfare article  where I explained (among other things) why the Supreme Court's recent decision in Louisiana v. Callais doesn't justify packing, and in a July UnPopulist article critiquing a court-packing proposal advanced by Andy Craig. In these pieces, I explain why the Court's record of checking dangerous abuses of government power - though not without serious flaws - is considerably better than many critics claim. In addition, I argue that court-packing is likely to undermine effective judicial review - not only by the Supreme Court, but also by lower courts.

Like Vladeck, I think some of the issues that concern critics of the Court can be more effectively addressed in other ways. For example, in the Lawfare article, I explain how Congress can fix the flaws of the Callais decision by banning or restricting gerrymandering. It could also enact a binding ethics code for the justices. Justice Alito was wrong to suggest otherwise, back in 2023. That said, if your main goal is a sweeping reversal of much of the Court's recent jurisprudence, there may be no easy way to achieve that quickly without court-packing or something like it. I would argue that any benefits that might achieve are outweighed by the enormous costs of destroying judicial review.

In addition, if your objection to the Court's recent decisions is that they often don't do enough to constrain unconstitutional actions by other branches of government or by the states, court-packing is likely to make that problem worse, not better. Destroying judicial review won't enforce tighter constitutional constraints on the executive or bring back Roe v. Wade. To the contrary, it would largely destroy any hope of doing so.

In another recent piece, I assessed "non-packing" rationales for increasing the size of the Supreme Court. There, I argue that these rationales are mostly weak; and, to the extent they have merit, there are better ways to address them than an expansion that amounts to court-packing. I even outline possible ways to increase the size of the Court without creating an opportunity for court-packing (this would require allowing the party that doesn't hold the White House to pick some of the new justices).
