Read the opinions. Both are pretty reasonable. I think the dissent has a good point that a plain language interpretation of the term "regulate imports" would seem to include tariffs.
The bigger issue I think is that that statute exists in the first place. "Emergency powers" that a president can grant himself just by "declaring an emergency" on any pretense with no checks or balances is a stupid idea.
