Tariffs Ruled Unlawful, Again. It Still Won't Matter.
What happened
The US Court of International Trade ruled 2-1 on May 7 that Trump's 10% global tariffs, imposed in February under Section 122 of the Trade Act of 1974, are unlawful. The ruling found that Trump exceeded the tariff authority Congress granted under that law. However, the injunction is narrow: it protects only two private importers who sued and the State of Washington, leaving the levies intact for all other importers while the administration appeals. The tariffs are in any case set to expire in July. On the same day, Trump issued the EU a July 4 deadline to implement a trade agreement, threatening steeper tariffs if Brussels does not comply.
Every court that touches Trump's tariffs calls them illegal, and the tariffs keep running anyway. The legal system is producing verdicts; the executive branch is producing delays.

The Hidden Bet
Court losses are weakening Trump's tariff leverage.
The July 4 EU ultimatum landed on the same day as the court ruling, and Trump did not soften it. Trading partners read court losses as political noise because the administration has shown it will impose new tariffs under different legal theories whenever a court strikes one down. The threat is not the specific tariff; it is the demonstrated willingness to keep imposing them.
The July expiration of these 10% tariffs resolves the issue.
The administration issued the July 4 ultimatum to the EU in parallel. If EU negotiations fail, new tariffs will replace the expiring ones. The court ruling does not bind future tariff orders; it only invalidates this specific invocation of Section 122.
Polymarket's 94% probability that courts force tariff refunds means the legal strategy is failing.
Refunds on past tariffs are a cost of doing business for an administration that views tariffs as a foreign policy tool rather than a revenue mechanism. The administration may calculate that even if it loses every legal challenge retroactively, the coercive effect during the pendency of each appeal was worth the eventual refund cost.
The Real Disagreement
The real fork is not whether the tariffs are legal. Courts keep saying they are not. The real fork is whether judicial review of executive trade power is a meaningful constraint on this administration, or whether it has become a slow-motion formality that the executive treats as a manageable delay. If courts are a real check, the administration will eventually run out of legal theories. If courts are just a delay mechanism, every ruling is pyrrhic. The evidence so far points toward the second: the IEEPA tariffs were struck down, and the administration immediately re-imposed under Section 122. Section 122 is now struck down, and the EU ultimatum went out the same day. The pattern matters more than any single ruling.
What No One Is Saying
The Court of International Trade's 2-1 split is doing the same political work as Trump's 'love tap' on Iran: creating a record that something was contested, so no one has to take responsibility for a permanent outcome. A unanimous ruling would force the Supreme Court to take it up immediately. A split ruling creates grounds for appeal and buys the administration another three to four months of enforcement.
Who Pays
Small US importers not party to the lawsuit
Ongoing until July expiration, assuming no new tariff replaces it
The injunction does not protect them. They are paying the 10% tariff and waiting for their own legal proceedings or for the July expiration. Unlike large corporations with lobbying access, they cannot negotiate bilateral exemptions.
EU automakers and exporters
July 4 deadline; tariffs would activate within days of that
The July 4 ultimatum, if not met, triggers higher tariffs on European cars and goods. The EU has limited retaliatory options that do not hurt European consumers and manufacturers who depend on US components.
US consumers
Distributed across the duration of tariff enforcement; no recovery mechanism
Even if courts order refunds to importers, there is no mechanism to pass those refunds to end consumers who paid higher prices. The cost was already absorbed.
Scenarios
Legal whack-a-mole continues
The administration appeals, the Section 122 tariffs keep running for the vast majority of importers, and they expire in July before the appeal is resolved. New tariffs on the EU activate after July 4 under a different legal authority. The net tariff burden on trade remains roughly constant while courts process each challenge.

EU deal before July 4
Facing the deadline and pressure from German and French industry, the EU agrees to a framework on trade that satisfies Trump's minimum threshold. EU tariffs are paused. The court ruling becomes moot for US-EU trade even if it stands legally.

Supreme Court forced to act
A circuit split emerges on executive tariff authority. The Supreme Court takes the case and rules more broadly on presidential trade power under IEEPA and Section 122. A sweeping ruling constrains the executive's ability to impose future tariffs without explicit Congressional authorization.
Signal Polymarket probability on court-forced tariff refunds rises above 97%. Administration signals it will seek emergency stay at the Supreme Court.
What Would Change This
If the Supreme Court issued a broad ruling that explicitly tied presidential tariff authority to explicit Congressional authorization, the bottom line would be wrong: the legal system would have produced a durable constraint, not just delays. Alternatively, if the EU signed a real trade deal with binding terms before July 4, the tariff threat to Europe would be genuinely resolved rather than deferred.
