The problem with the Chevron ruling was it allowed the Government to create extra judicial tribunals that had original jurisdiction over every case that arose from federal regulation. And the courts essentially washed their hands of it and said “no appeal”.
Think about how screwed up that is, beaurucrats create regulations, they prosecute under this regulations, and then they get to judge themselves on whether or not they were right in bringing prosecution.
Don’t get me wrong my sympathy for most corporations is zero but it was a massive expansion of government power with zero checks to it and it needs to be done away with.
