I don't understand where this belief is coming from. The judgement explicitly states that writing unambiguous laws isn't possible. There will still be ambiguous laws, and those ambiguities will still be resolved. The only matter being decided on is who gets to resolve ambiguities - is it the agencies or is it the courts.

Let's put this another way. Did Congress have to write unambiguous laws or have them be unenforceable before 1984? Clearly not. The Constitution itself is ambiguous on many points. Do other countries, which lack any equivalent of Chevron deference, have to write unambiguous laws or have them be unenforceable? Again, clearly not.

I think we are agreeing here. I think the distinction is that I'm claiming the courts would need (yet don't have) the expertise to clear up ambiguities in such domains. Where do I get this claim? From the justices themselves.[1] There is evidence they are overly confident in their understanding when "doing their own research" on a domain outside their expertise.[2]

So given that context, it's probably a bad idea to have justices decide on ambiguities. But if that power resides in them now, it means the only way to have effective laws is to avoid ambiguities in the first place. That's why I stated that is now on Congress. However, the court is also acknowledging that isn't possible. That's why I originally said it reads like they created a deliberate stalemate. From the court we have the following:

1) Congress cannot be expected to create unambiguous laws.

2) It is the court's job to resolve ambiguities.

3) The court lacks domain expertise.

I'm claiming those set up a natural conflict because expertise is necessary to effectively resolve ambiguity.

The most generous interpretation is that the justices don't need to know the details of the domain expertise, but rather just need to know how it interfaces with people and the law.[3] I'm pretty skeptical of that leading to good outcomes in complex, nuanced situations. I don't think we can pretend law is abstractly disconnected from the complex systems it regulates. As society progresses, most things get more complex so I expect the problem to get worse, not better.

There's certainly no evidence of an attempt to create a deliberate stalemate here, as "laws that judges cannot interpret even with help" isn't something the Supreme Court is going to consider a legitimate problem to begin with so why would they consider it? But it's fascinating the degree to which some people on this thread are sure this is all a cunning secret plan by the justices to advance a political ideology. Projection, much?

Great. So are regulators, politicians and especially journalists. The idea that agencies never rely on bogus claims or statistics is a deeply romantic view.

Really, I don't have any sympathy for the US regulatory agencies on this issue. Too many of them have a history of abusing Chevron deference. If the deference standard had any advantage at all it'd be that you could get binding rulings from regulators ahead of time, without needing to actually end up in court first. But regulators always refuse to do that, because they aren't obliged to and it would reduce their options. Instead what they do is make vague rules, tell citizens (e.g. entrepreneurs) who ask for clarification to get lost, wait years for some of those people to make successful businesses and then decide that what they were doing had been illegal all along under some strange interpretation of the relevant rule. It's a form of retroactive lawmaking, which is forbidden by basically any constitution because the whole point of law is that people are meant to be able to follow it.

This sort of abusive behavior is so common it's clearly deliberate. Instead of helping society, the agencies end up working against it in order to maximize their own power.

Having the people who interpret laws be fully separated from those who write the laws aligns incentives properly: there's no longer any benefit to passing maximally vague or contradictory rules in the hope of being able to do whatever you want later. Laws that are as specific and clear as possible is exactly what a society needs to succeed, because when the rules are clear people are free to innovate and do business without fear.

Yes. The important distinction that I drew was that the power is now vested in a very small group of nine people. IMO that measures it much easier for biases to continue unabated. At least in large numbers, there are more likely to be more rational viewpoints to counter our innate biases.

Maybe, but there is absolutely no mechanism to ensure that rational viewpoints will prevail in a group of large numbers, and quite a large danger of social pressure causing less rational viewpoints to prevail instead.

If the court makes an unreasonable interpretation, the only mechanism to rectify it is for Congress to be explicit. This has multiple problems: first, getting anything through Congress is becoming increasingly difficult. Secondly, the Court already admitted that laws will always have ambiguities because Congress doesn't always have the expertise to be that explicit. From that standpoint, the Court has claimed a power while acknowledging there is very little in terms of a check on that power.

Yes, but this is a system where everyone involved is trying to (help their team) win rather than trying to produce generally efficacious policy.

Despite its reputation for not passing any laws, the last session of Congress still passed a fair number of laws: https://legiscan.com/US/legislation/2021?status=passed

(The current one seems to be a fair bit behind, but it is also operating on razor thin vote margins and the session is not over yet).

I think we can all agree that the best solution is unambiguous laws, but that’s an impossibility by the courts own admission. Chevron already had a mechanism to prevent agency overreach by giving the court discretion to determine the reasonableness of an agency interpretation. This now just puts the onus on the court to do it all, and they admit they don’t have domain expertise. I fail to see how that is a better solution.

I don’t want the domain experts to have an easy time of it. The law is not their convenience, it is for the peace and prosperity of the Republic, and given that Agency interpretations can change on a dime (up until recently) with almost minimal justification from a new administration, I don’t want to defer to staff who are charged with interpreting laws in a way more favorably for their new bosses, even if it goes against how they did business under their old ones to have an easier time making their case in court. The law should be more concrete than some mere electoral promises and wishful policy-thinking.

Ideally. In practice ambiguities in statutes governing agency mandates are always interpreted by agencies in whatever way would maximize their own options and power. That's the written justification for the APA in the first place: reeling in excessive "zeal" amongst administrators.

The courts don't get powers from the law directly (except meta-powers like the one this case is about), so there's no direct benefit to judges from interpreting law in a maximally agency-advantageous way. That's why countries (not just the US) have courts resolve ambiguous law. It's a core part of their job.

An abuse of a form doesn't invalidate that form's validity.

I would be logically incoherent to assert that all hamburgers are crap on the basis of having worked at McDonalds for years.

Nobody has a career as an expert witness for long if they go against a client's wishes. There is no such thing as an impartial expert witness in the current system. They're all hired by one side or the other. They're basically subject-matter expert lawyers.

> There is no such thing as an impartial expert witness in the current system

You're saying a form is bad because it doesn't line up with how it ought to be (you said "impartial"). But in saying so, you imply there is an ought. That is the real form (what it ought to be): an impartial expert witness.

When a form only presently exists in an abuse thereof, that doesn't necessarily invalidate the form as a worthy pursuit.

History can tell us whether such a form is worth pursuing. Expert witnesses in the US have been more or less impartial in the past. Communism has never been achieved, and its pursuit has never led to well-being of the people. Both are "ideal forms" in a philosophical sense, but history bears out which is worth pursuing and practically achievable.

So my take is that what's needed is reform of expert testimony through congressional law, including independent review of DAs, to ensure they prosecute expert witnesses who failed a legal impartiality test.

I'm arguing for better enforcement via law, to ensure witnesses are either impartial or prosecuted for impartiality.

If partial witnesses aren't being prosecuted, then launch an inquiry and do a causal chain analysis. It's bound to turn up a root problem that is solvable.

The left tend to argue that impartial people exist, and that they are numerous/easy to find.

The right tend to argue that there's no such thing as an impartial person, that you can get people who start out partial and do their best to be fair (e.g. judges) but it takes constantly training, reinforcements and incentives to do that and there's always the danger of slipping back. You definitely can't assume it.

The adversarial court system is based on the right-leaning belief: although expert witnesses are told to be impartial, the system doesn't assume this is enough and so witnesses are called by one side and cross-examined by the other. The lawyer's job is to sniff out any signs of bias or incompetence.
