This week we talk about the APA, the Supreme Court, and Marbury v. Madison.We also discuss the Chevron Doctrine, government agencies, and the administrative state.Recommended Book: A City on Mars by Kelly and Zach WeinersmithTranscriptThe Supreme Court's 1803 Marbury v. Madison decision was pivotal to US legal theory and practice because it established the concept of judicial review, which essentially said that US courts could assess laws passed through the typical legislative system, through Congress, and, if they determined those laws were unconstitutional, strike them down.This was a huge rewiring of the US government, as it gave a substantial amount of new power to the court system, and it provided a new check on the legislative system that recentered the Constitution as the source of all law; if the judges decided new laws didn't line up with that original Constitutional intent, according to their interpretation of said intent, the new laws would be a no-go.This is true of statutes that declare policy, as well, which are generally part of the law-making process, and also help shape regulations, guidelines, and other things of that nature—the fuzzier stuff that goes on to effect things, even when some of those fuzzy statements and implications aren't formalized in law, yet.So any and all of this stuff that Congress decides on could, at some point, be looked into by the US court system, and that system can say, nope, that doesn't line up with what's in the Constitution—it's not Constitutional—and that means the Constitution, following Marbury v. Madison, became a lot more of a legal reality in the country, rather than just a collection of principles and ideals, which is how some legislators and legal scholars thought of it before this ruling.Within this same entwined governmental/legal system, Congress sometimes delegates policy decision-making powers to US agencies, allowing them to make legal decisions in cases where Congress passes a law that it is some way ambiguous—saying that there need to be emissions standards on cars, for instance, but leaving the task of coming up with those standards to the Environmental Protection Agency, the EPA.This delegation ability was reinforced by a 1984 Supreme Court decision, Chevron v. The Natural Resources Defense Council, today usually referred to as "Chevron" or the "Chevron decision," the justices unanimously deciding against the DC judicial circuit's ability to set government policy, reminding those justices that judges are unelected officials and thus shouldn't be making law, and that when Congress isn't specific enough in their lawmaking, this can represent an implicit desire for the agencies in charge of implementing the relevant laws in the real world to figure out the specifics for themselves; after all, they would probably know better how to do so than a bunch of lawmakers who are not experts on the subject matter in question.That case also limited the US court system's ability to review an agency's interpretation of the law, which in that specific case meant that judges shouldn't have the right to look into how US agencies decide to do things, willy-nilly, just because they don't like the outcome.Instead, they have to adhere to what has become known as the Chevron Doctrine or Chevron Deference, which says, first, the judges have to decide if Congress was clear on the matter—and if so, they go with what Congress said, no questions asked. If Congress was unclear on something, though, then they have to decide if the agency in charge of executing Congress' decision has made reasonable and permissible decisions on that implementation; and if the answer is yes in both cases, the court must accept the agency's decision on the matter.If not, though, then the court can step in and make some kind of judgement; but it's a fairly ponderous process to get to that point, because of this doctrine, and they will almost always defer to the decision made by the relevant agency, because of th
