Expired Authority?: Federal Court Suggests 
Some Limits to the President’s Authority to 
Impose Tariffs 
November 27, 2019 
In response to perceived unfair trade practices of other countries, the Trump Administration has imposed 
tariffs and other trade restrictions on billions of dollars of imported products using authority Congress 
delegated to the executive branch in various provisions of federal law. To justify the trade measures, the 
Administration has cited national security concerns, injury to competing domestic industries, and 
allegedly unfair trade practices of particular countries (e.g., China’s practices with respect to intellectual 
property rights). Some industry groups and individual companies have challenged these tariff actions on 
constitutional and statutory grounds in U.S. courts but, until recently, federal courts have uniformly 
rejected these challenges. (This Sidebar does not discuss the challenges to certain tariffs currently pending 
before the World Trade Organization (WTO) or other international bodies.) 
A November 15, 2019 decision by a three-judge panel of the U.S. Court of International Trade (CIT), 
however, marks a departure from this trend in the case law, which could have broader implications for the 
scope of the President’s trade powers. In Transpacific Steel LLC v. United States, a U.S. company sought 
a partial refund of duties it paid on certain steel imports from Turkey. The imports were subject to tariffs 
the President imposed under Section 232 of the Trade Expansion Act. In a decision denying the United 
States’ motion to dismiss the company’s complaint, the CIT indicated that the President’s power to 
impose tariffs under Section 232(b), while broad, is not unlimited. Specifically, the court suggested that 
the President must closely adhere to the procedural requirements of the statute when exercising such 
authority. This decision, which this Sidebar explores in more detail, could have implications for future 
tariff actions under Section 232 and similar statutes granting the President power over foreign commerce.  
Section 232 Trade Measures 
As discussed in this CRS Report, Section 232 authorizes the President to impose restrictions on certain 
imports based on the U.S. Department of Commerce’s (Commerce’s) affirmative determination that the 
product under investigation “is being imported into the United States in such quantities or under such 
circumstances as to threaten to impair the national security.” The Act establishes deadlines that

Commerce and the President must meet during each phase of the investigation and implementation of any 
resulting action.  
Specifically, under the Act, Commerce must, within 270 days of initiating an investigation, consult with 
other federal agencies and submit to the President a report of its findings, including a determination of 
whether imports of the article under investigation threaten national security and a description of any 
recommendations to resolve the threat. If Commerce makes an affirmative determination of a threat, the 
President has 90 days after receiving the investigation report to determine whether he concurs with 
Commerce’s findings. If the President concurs, he must also determine what actions to take to remove the 
threat to national security and implement any such action to “adjust imports” within 15 days. 
In April 2017, the Secretary of Commerce initiated an investigation under Section 232 to determine the 
effect of steel and aluminum imports on national security. In January 2018, the Secretary timely submitted 
to the President a report finding that certain steel imports posed a threat to national security. On March 8, 
2018, the President proclaimed a 25% tariff on imports of steel from nearly all U.S. trading partners, 
including Turkey, which took effect on March 23. In August 2018, the President proclaimed an increase in 
Section 232 tariffs from 25% to 50% only on Turkish steel imports. That increase was later lifted in May 
2019. 
The Transpacific Steel Decision 
In Transpacific Steel, a U.S. company that imports steel products from various countries, including 
Turkey, seeks the refund of the allegedly excess duties it paid on imports of Turkish steel. The company 
argues that the President lacked authority to proclaim the subsequent increase in tariffs on steel imports 
from Turkey (i.e., from 25% to 50%) because it became effective five months after the initial imposition 
of steel tariffs and well beyond the statutory deadline for action in the underlying steel investigation. The 
company also maintains that the imposition of the tariffs lacked a sufficient national security rationale and 
violated the plaintiff’s Fifth Amendment Due Process and Equal Protection rights because the action 
“creates an arbitrary distinction between importers of steel products from Turkey and importers of steel 
products from all other sources.” 
The government moved to dismiss the company’s complaint for failure to state a claim. To survive such a 
motion, a plaintiff need only show that it has a “plausible” claim for relief, which generally requires 
proffering facts “plausibly suggesting (not merely consistent with) a showing that entitles the party to 
relief.” In a decision denying the government’s motion, the CIT determined that the company’s allegation 
that the President failed to follow Section 232’s procedural requirements when imposing the tariffs 
established a plausible claim for a partial refund of the duties. Specifically, the court concluded that the 
President lacked power to act beyond the deadline to impose additional tariffs without initiating a new 
investigation, deeming such an “expansive view of [presidential] power under section 232” to be 
“mistaken, and at odds with the language of the statute, its legislative history, and its purpose.” The court 
also noted that, while the President retains significant discretion to impose duties under Section 232, 
Congress intended the President to adhere strictly to the “procedural safeguards that Congress provided, 
and which the President appears to have ignored.”  
The court also determined that the company established a plausible argument that the Executive violated 
constitutional guarantees of equal protection protected by the Fifth Amendment’s Due Process Clause 
when imposing, without a rational basis, the additional steel tariffs only on imports from Turkey. The 
court observed that while the equal protection standard is “forgiving” in the context of economic 
regulation, the government had not offered a sufficient justification for treating imports of steel from 
Turkey differently than those of other countries.

Implications of the Decision 
The CIT’s decision in Transpacific Steel suggests that, for the first time during the Trump Administration, 
courts may impose at least some limits on the President’s use of statutory tariff authorities. However, 
there are limits to the reach of the decision. While the decision suggested various potential limits on the 
President’s authority to impose tariffs, it was issued in the context of a narrow factual situation: tariffs 
imposed on imports of steel from one country after the statutory deadline for action had passed. Thus, 
although the three-judge panel decision amounts to binding precedent in future CIT cases, some of the 
broader statements in the court’s opinion regarding the President’s authority under Section 232 may 
constitute nonbinding dicta because they are not essential to resolving the specific dispute at issue in the 
case. Furthermore, the court’s decision could later be overturned on appeal to the Federal Circuit Court of 
Appeals. 
Nonetheless, the decision suggests several avenues by which courts could limit the President’s use of 
tariff authorities. While courts have previously rejected challenges to the President’s fact-finding and 
selection of a remedy under various trade statutes, the decision in Transpacific Steel indicates that courts 
might scrutinize whether the executive branch has followed the proper procedures, including meeting 
statutory deadlines. Presidential action that does not follow these statutory procedures may be deemed in 
excess of the President’s authority. In addition, the court indicated that, under Section 232, the President 
lacks the authority to adjust national security tariffs after the deadline unless Commerce conducts a new 
investigation and issues a new report recommending action. 
In addition, some possibility exists that the federal judiciary will determine that some of the statutes 
granting expansive trade authority to the President are unconstitutional. In a concurring opinion in 
Transpacific Steel, Judge Gary Katzmann repeated some of the concerns he raised in an earlier 
constitutional challenge to the President’s Section 232 actions. In American Institute for International 
Steel, the CIT rejected an argument that Section 232 was an unconstitutional delegation of legislative 
power. In a separate dubitante opinion, Judge Katzmann concluded that, although the CIT was bound by a 
1976 holding of the Supreme Court, it might be time to revisit the assumptions of that holding because it 
has become clear that Section 232 “provides virtually unbridled discretion to the President with respect to 
the power over trade that is reserved by the Constitution to Congress.” After the Supreme Court declined 
to grant certiorari to hear a direct appeal of the CIT’s decision in American Institute and potentially 
reconsider its earlier precedent on the constitutionality of Section 232, an appeal of the CIT’s decision 
remains pending at the U.S. Court of Appeals for the Federal Circuit. 
The Transpacific Steel decision may also have legal implications for future tariff actions. One legal 
commentator has argued that the President lacks authority to impose Section 232 national security tariffs 
on imports of automobiles and automotive parts pursuant to an earlier investigation because the President 
missed the statutory deadline for action. However, others have suggested that the President might rely 
upon language in Section 232(c)(3) that appears to authorize the President to take additional actions to 
adjust imports (e.g., impose tariffs) if he unsuccessfully attempts to negotiate an agreement to resolve 
concerns about imports that threaten national security within 180 days of determining to take action under 
the law. President Trump had directed U.S. negotiators to reach agreements with the European Union and 
Japan to address auto imports; however, no such agreements have been finalized. (Other trade authorities 
may also provide the executive branch with authority to impose tariffs on automobiles.) 
Although it is possible that the federal courts will further clarify the scope of the President’s authority to 
impose national security tariffs, Congress could also consider enacting legislation to alter or clarify the 
executive branch’s existing authority under Section 232. Several bills introduced in the 116th Congress 
address concerns about Section 232, including expanding, limiting, or revising existing authority.
