Well it is probably going to go one of three ways.We're supposed to hear this month.
From the court reporting, it sounds like SCOTUS will shoot them down.
First SCOTUS might actually strike down Trump's tariffs completely. I find that the least likely scenario.
Second SCOTUS will strike down Trump's tariffs in a way that makes them look "clean" while Trump has an out to use another excuse to maintain the tariffs, which he has already foreshadowed doing. This is probably the most likely scenario.
Third SCOTUS actually upholds the tariffs by using some wild reasoning related to some super obscure law from more than 100 years ago. This is my second most likely scenario.
