I’m actually surprised the Court even granted cert on this case. It’s pretty long established that states can set whatever rules they want for things like this as long as those rules aren’t different for an in-state producer as they are for an out-of-state producer. That’s even much longer established precedent that Roe was. I remember studying a couple of milk lawsuits from 100+ years ago when I took Constitutional Law that settled this issue.
As far as the seemingly surprising mix of justices in the majority…when you have cases like this that don’t trip social-ideology triggers for politicians and pundits, you see a lot more mixing up of the traditional liberal vs. conservative justices. RBG, for example, often sided with Scalia on commerce questions like this.
