 It's how out-of-control agencies have been able to create rules out of thin air and force you to comply and the courts had to simply defer to them because they were the, quote, experts. It was not only blatantly unconstitutional, it caused immeasurable harm to everyone. We haven't even begun to feel the effects of this decision in the courts. It'll be used for years to come to roll back federal agencies and we all will be better for it.
