Supreme Court Tariff Decision Still Leaves Options for Trump, Legal Expert Says

A recent ruling by the Supreme Court of the United States blocking the use of emergency powers to impose sweeping tariffs may still leave Donald Trump with several legal pathways to continue his trade agenda, according to legal analysts.

Although the Court rejected the administration’s reliance on the International Emergency Economic Powers Act (IEEPA) to impose global tariffs, some experts say the ruling did not eliminate presidential tariff authority entirely.

Instead, they argue the decision suggests alternative statutes that could allow tariffs under narrower conditions.

Justice Kavanaugh’s Dissent Suggests Alternative Path

Legal analyst Elliot Williams said the dissent written by Brett Kavanaugh effectively outlined a potential “roadmap” for the administration to continue imposing tariffs.

Speaking on The Bulwark’s podcast Illegal News, Williams explained that Kavanaugh argued the president likely relied on the wrong legal authority rather than lacking tariff powers altogether.

According to Williams, the dissent indicated that other laws might provide limited authority for tariffs.

“Justice Kavanaugh did sort of lay out a roadmap,” Williams said, noting that several statutes could support targeted tariff measures.

Other Trade Laws Could Support Tariffs

In his dissent, Kavanaugh referenced several laws that allow presidents to impose tariffs under specific circumstances, including:

• Trade Expansion Act of 1962
• Trade Act of 1974
• Tariff Act of 1930

These statutes can authorize tariffs, but they come with stricter conditions than the emergency powers Trump previously used.

Typically, they require:

• Formal investigations
• Detailed economic or security findings
• Limits on the scope or duration of tariffs

Kavanaugh wrote that the administration may have simply “checked the wrong statutory box” by relying on the emergency powers law.

Trump Moves Forward With New Tariff Plan

After the ruling, Trump said he supported Kavanaugh’s dissent and indicated that the administration would shift to other legal authorities to maintain tariffs.

The White House has already begun implementing tariffs under Section 122 of the Trade Act of 1974, which allows temporary tariffs in response to trade imbalances.

Trump reiterated his commitment to the policy during a national address, saying tariffs would remain in place while alternative legal frameworks are explored.

He also repeated a long-standing argument that tariffs could eventually replace income taxes as a major source of federal revenue.

New Tariffs Face Strict Time Limits

Legal experts note that the administration’s current approach has significant limitations.

Section 122 allows tariffs of up to 15 percent, but only for a maximum of 150 days unless Congress approves an extension.

Analysts say that political support for renewing those tariffs in Congress appears uncertain.

As a result, the administration may eventually need to pursue different legal authorities if it wants to maintain tariffs beyond the temporary window.

Experts Say Tariffs Will Be Harder to Expand

Williams explained that the Supreme Court ruling significantly reduces the president’s ability to impose sweeping tariffs quickly.

He compared the situation to winning a luxury car but being forced to drive a much older vehicle instead.

In other words, tariffs remain possible, but they will likely be more limited, slower to implement, and subject to stricter legal scrutiny.

“It is impossible for the president to get the kinds of tariffs that he ran on and tried to implement earlier,” Williams said.

Administration Says Strategy Remains the Same

Despite the legal setback, Jamieson Greer said the administration intends to continue pursuing its existing trade strategy.

According to Greer, the Court rejected only one legal tool used to impose tariffs, not the overall policy.

“The trade policy we’ve had for the past year is going to remain the same,” Greer said.

He added that Congress has already granted several authorities that can be used to pursue similar tariff policies.

Trade Policy Battle Likely to Continue

The ruling represents a major moment in the ongoing debate over the limits of presidential authority in trade policy.

While the Court blocked the broadest version of Trump’s tariff program, legal experts say the decision leaves open a range of narrower options that could still allow the administration to impose tariffs — setting the stage for continued legal and political battles over U.S. trade policy.
