> The National Association of Manufacturers, an industry group, made an even more sweeping argument in a brief filed in support of the companies, writing, "state courts are not positioned to decide who, if anyone, is to be legally accountable for climate change, how energy policies should change to address it, and how local mitigation projects should be funded."

It's true that courts cannot do all three, I doubt that courts are trying to create policies, that seems a straw man argument. But "decide who, if anyone, is to be legally accountable for X" seems the main job of courts.

Companies lied to and/or mislead consumers with grave consequences to their health and economy. I see that to attribute a concrete amount on damages is challenging, but courts do it all the time.
