The case was filed on behalf of five owner-operated businesses who claimed severe harm from the tariffs: V.O.S. Selections, FishUSA, Genova Pipe, MicroKits LLC, and Terry Precision Cycling.
I would be interested who the owners (US or overseas) are of these firms.
My guess is that they’re all locally owned, but even if they’re not it’d be immaterial to their standing. If you, a US citizen, own an apartment in Munich or a bike shop in Vancouver you’d be entitled to equal protection under German or Canadian law.
So is the complaint about harmed caused or POTUS authority? All forms of revenue cause harm.
