On May 28th, according to Vox, the U.S Court of International Trade – based in New York – ruled that Donald Trump’s Liberation Day tariffs are illegal.1 They have three reasons:
1: The International Emergency Economic Powers Act of 1977 (IEEPA) does not grant the president power to have ‘unchecked’ power when it comes to tariffs. Vox says the court concluded that, “the statute cannot be read to give Trump unchecked authority over tariffs because, if Congress had intended to give Trump that power, then the statute would violate the Constitution’s separation of powers because Congress cannot simply give away its full authority over tariffs to the president.” 2
2: That the tariffs violate section 122 of the Trade Act of 1974 – which dictates that if need be the president can impose tariffs of 15% for 5 months to regulate a trade deficit – because on many countries they exceeded 15%.3
3: That the tariffs do not “deal with an unusual and extraordinary” threat as the IEEPA would require. Vox says the court, “rejects the argument that the tariffs can be justified because they pressure other nations to shift their domestic policies.“4
I have three responses for each of these claims.
1: The court is mis-interpreting the IEEPA.
- The IEEPA does not give ‘full authority.’ What this act does is, “…authorizes the President to investigate, regulate, and prohibit certain financial transactions following a declaration of an “unusual and extraordinary threat” originating outside the United States.”5 This is not full, permanent authority. This is emergency and immediate action (which congress fails at) taken after a credible threat to the nation has been established, and then removed when said emergency is also removed. Of course congress cannot abdicate total authority over commerce regulation, but it can certainly delegate aspects of it when it fails to meet an emergency quick enough.
2: The court is applying the wrong law.
- Let me explain: If the court were to use the Trade Act of 1974 to justify their ruling, they wouldn’t be able to use the interpretation of the IEEPA, because the 1974 Act would take higher precedence over the IEEPA – if the 1974 act applied to every single commerce regulating instance ever. FYI, it doesn’t. Trump also declared a national emergency regarding the trade deficit.6 This means that this particular argument related to the IEEPA, because it deals with a national emergency. The 1974 Act says nothing about regulating tariffs in a time of declared emergencies.
3: Shifting foreign policy, not domestic.
- The court claimed that the tariffs, according to Vox, were not justifiable because, “[H]owever sound this might be as a diplomatic strategy, it does not comfortably meet the statutory definition of ‘deal[ing] with’ the cited emergency.” 7 What was the cited emergency? According to the White House fact sheet on the Liberation Day tariffs it is, “The extraordinary threat posed by illegal aliens and drugs, including deadly fentanyl.”8 The emergency was the smuggling of fentanyl into the U.S by the transnational crime organizations that are under the jurisdiction of China, Canada, and Mexico. This wasn’t a move to shift another countries domestic policies, they don’t relate to the U.S. This was a move to shift the foreign policy attitude towards us by not letting this illicit drugs come across our border anymore, by preventing their criminals from encroaching on our borders and committing atrocities in our country, something that in a different world would be considered an act of war. Possibly Mexico, Canada, and China will have to make some domestic policy shifts, but the U.S only cares about policy that relates to ourselves and how their relation, attitude, and actions towards us hurt or help us, not their domestic policy – which has no relation to us.
- We can also see that not only are tariffs justifiable in curbing illegal drug smuggling into the U.S, they are also working. In March, one month after Trump announced the tariffs, according to U.S Customs and Border Patrol (CBP), 7,181 illegal aliens were apprehended crossing the southwest border.9 They say, “This constitutes a 14% decrease from February 2025 when USBP apprehended 8,346 aliens, and a 95% decrease from March 2024 when USBP apprehended 137,473 aliens.”10 Less immigration equals less flow of fentanyl, because there’s less people to smuggle drugs. If cutting out the source of the emergency isn’t ‘dealing with’ the emergency as the court claims, then clearly ‘dealing with’ has a different definition than I thought it did.
