It was already the case that the courts were having to delegate to expertise they didn’t have (this is a frequent occurrence and not something new) the difference is previously courts had to delegate to government experts and now they don’t.
The courts have long used 'expert witnesses' to make decisions, I expect this will just become even more common going forward. And many times these so-called 'experts' are in fact provided by the very industries that would be affected by legislative decisions. On the surface what looks like a significant increase of power by the judiciary seems really to be effectively an additional capture by corporations.
Maybe it was already that way by a different route, but still.
