Kentucky Joins Multistate Lawsuit Challenging Trump Tariffs Under the Trade Act of 1974

After the Supreme Court struck down earlier tariffs, states argue the administration is using a different statute to restore broad tariff power

Mar 06, 2026

On March 5, 2026, a coalition of 24 states filed a lawsuit challenging a new set of tariffs imposed by the Trump administration under Section 122 of the Trade Act of 1974. The case was reported by Reuters and filed in federal court shortly after the U.S. Supreme Court struck down a large group of earlier tariffs that had been imposed using different statutory authority.

Kentucky is among the plaintiff states.

The lawsuit argues that the administration is attempting to reassert broad tariff power after the Court rejected its earlier approach. Instead of abandoning the policy, the administration invoked a separate section of federal trade law to impose a new set of tariffs that function in a similar way.

That shift is now the central legal question. The states argue that the executive branch cannot effectively recreate the same policy outcome under a different statute after a judicial defeat.

For Kentucky, the case places the state government inside a national dispute over the boundaries of presidential trade power. It also highlights how federal trade decisions travel through courts, agencies, and markets before they reach local businesses and consumers.

The case arrives at a moment when several institutions are interacting at once: the White House, the federal courts, state governments, and the statutory framework Congress wrote decades ago to regulate international trade.

Understanding the dispute requires looking closely at how those pieces fit together.

The Supreme Court Decision That Triggered the Dispute

The immediate backdrop to the lawsuit is a recent decision by the U.S. Supreme Court that struck down a previous set of tariffs imposed by the Trump administration.

Those earlier tariffs were enacted under a different legal authority. The administration had relied on statutory language that allowed the president to impose tariffs in response to national economic or security concerns.

States, businesses, and trade groups challenged that approach in federal court. Their argument focused on whether the administration had exceeded the authority granted by Congress.

When the case reached the Supreme Court, the justices invalidated the tariffs, concluding that the administration had stretched the statutory authority beyond what the law permitted.

The ruling effectively halted the earlier tariff structure.

In practical terms, that decision forced the administration to either abandon the tariffs or locate another legal mechanism that could justify a similar policy.

Within weeks, the administration chose the second option.

The Administration’s Shift to Section 122 of the Trade Act

After the Supreme Court ruling, the administration invoked Section 122 of the Trade Act of 1974 to impose a new round of tariffs.

Section 122 allows the president to take temporary trade actions when the United States faces a serious balance-of-payments problem or a sudden deterioration in international economic conditions. The statute permits the president to impose tariffs or quotas for up to 150 days while the administration pursues broader trade negotiations or economic remedies.

The provision was originally designed as an emergency tool.

Historically, it has been used sparingly and typically for short-term stabilization efforts rather than long-term trade policy.

The Trump administration’s new tariffs rely on this authority.

According to the states’ lawsuit, the administration used Section 122 to recreate a tariff structure that resembles the earlier tariffs invalidated by the Supreme Court. The states argue that the administration is using a temporary emergency statute to achieve a policy outcome the Court has already rejected.

That legal claim forms the backbone of the multistate challenge.

The lawsuit asks the court to determine whether Section 122 can be used in this way or whether the administration is attempting to bypass the limits imposed by the earlier Supreme Court ruling.

Why Kentucky Is Part of the Lawsuit

Kentucky’s participation in the case reflects the state’s divided political structure.

The state’s attorney general is a Republican, but the governor is a Democrat. Reuters reported that Kentucky joined the coalition of plaintiff states under the authority of the governor’s administration.

Multistate lawsuits are a common mechanism used by state governments to challenge federal policy.

In these cases, several states combine their claims in a single federal lawsuit, arguing that a federal action harms their residents, their economies, or their regulatory authority. Courts often treat these cases as disputes over federal administrative power rather than partisan disagreements between governments.

Kentucky’s participation signals that the state believes the tariffs could affect its economy.

The state’s manufacturing and agricultural sectors depend heavily on international trade. Kentucky exports automobiles, aerospace components, bourbon, agricultural products, and industrial machinery to global markets. Many of those industries also rely on imported materials and components.

Tariffs change those economic relationships.

When tariffs raise the cost of imported goods, domestic companies may face higher input costs. When other countries respond with retaliatory tariffs, American exports can become more expensive abroad.

For Kentucky businesses operating inside global supply chains, the uncertainty created by repeated tariff changes can complicate planning decisions that normally span years.

The Institutional Question Behind the Case

Although the lawsuit focuses on tariffs, the deeper issue involves institutional boundaries inside the federal government.

The Constitution gives Congress authority over international trade. Over time, Congress has delegated portions of that authority to the executive branch through statutes such as the Trade Act of 1974.

Those statutes define when and how a president may impose tariffs without passing new legislation.

Courts review those decisions when states or businesses argue that the executive branch exceeded its delegated authority.

The Supreme Court ruling that struck down the earlier tariffs was one example of that review process. It represented the judiciary enforcing the limits written into federal law.

The new lawsuit raises a different question.

If the executive branch loses a court case under one statutory authority, can it achieve the same policy outcome under another statute?

The states argue that doing so weakens the practical effect of judicial review. Their claim is that a court ruling loses force if the executive branch can simply shift legal theories and recreate the same policy through a different statutory pathway.

Courts must now decide whether Section 122 permits that approach.

A Broader Pattern of Policy Re-Routing

The tariff dispute reflects a larger pattern that has appeared in several recent federal policy conflicts.

When courts block an executive action, administrations sometimes pursue alternative legal routes to achieve similar results. That strategy does not necessarily violate the law. Federal statutes often contain multiple provisions that overlap or operate in parallel.

The legal system expects agencies and administrations to interpret those statutes when implementing policy.

However, repeated use of alternative statutory pathways can change how institutional checks operate in practice.

If an administration can restore a policy after a court decision by invoking a different statute, the judiciary’s ruling may limit only the specific legal mechanism rather than the underlying policy objective.

The tariff case places that dynamic directly before the courts.

The outcome will help determine whether Section 122 functions as a narrow emergency tool or as a broader source of tariff authority that can substitute for other trade powers when those powers are challenged in court.

Help others understand how federal policy decisions travel through courts, agencies, and institutions before reaching Kentucky communities.

How Tariffs Reach Kentucky’s Economy

Tariffs begin as federal policy decisions, but their effects move through several layers before reaching local communities.

When the federal government imposes tariffs, the U.S. Customs and Border Protection agency enforces them at ports of entry. Importers must pay the tariff when goods enter the United States.

Those costs often move through supply chains.

Manufacturers that rely on imported components may face higher production costs. Distributors may raise prices to cover the new tariffs. Retailers may pass those price increases to consumers.

Export markets can also shift.

Other countries sometimes respond to U.S. tariffs by imposing their own tariffs on American products. When that happens, Kentucky exporters may face higher barriers in foreign markets.

The state’s bourbon industry has experienced this dynamic in earlier trade disputes. Retaliatory tariffs from European countries once raised the cost of American whiskey exports, reducing sales abroad.

Manufacturing sectors face similar exposure.

Kentucky’s automotive industry relies on international supply chains that move parts and materials across borders multiple times before final assembly. Tariffs imposed at any stage of that process can raise costs or disrupt production schedules.

Even when tariffs remain temporary, the uncertainty surrounding trade policy can affect long-term investment decisions. Businesses deciding where to build factories or source materials must consider whether tariffs will remain stable over time.

The lawsuit now underway could influence that stability.

What Happens Next in the Courts

The multistate lawsuit will move through federal district court before any potential appeals.

The court will examine several key questions.

First, it must determine whether the plaintiff states have legal standing to challenge the tariffs. States typically establish standing by showing economic harm to their residents or state economies.

Second, the court will analyze the statutory language of Section 122. Judges will examine whether the conditions required by the statute have been met and whether the administration’s use of the provision falls within the limits Congress established.

Third, the court may consider how the new tariffs relate to the earlier Supreme Court ruling. While the legal authorities differ, the court will likely examine whether the administration’s actions undermine the practical effect of that decision.

The case could move quickly if the states request a preliminary injunction to halt the tariffs while the litigation proceeds.

If the district court issues a ruling, the losing party is likely to appeal to the U.S. Court of Appeals. Given the national importance of presidential tariff authority, the dispute could eventually return to the Supreme Court.

That process could take months or longer.

During that time, businesses and state governments will continue watching the case closely because the outcome will determine how much flexibility the executive branch has when using emergency trade statutes.
