Congress passes a law. An agency fills in the operational details. The public feels the impact. And somehow, no one can quite identify the moment when elected lawmakers made the big choice.
That, in plain English, is the constitutional itch behind a new push to get the Supreme Court to take a case involving the Environmental Protection Agency and the market for hydrofluorocarbons, the chemicals used in refrigerators, air conditioners, and other cooling devices.
The petition comes from Choice Refrigerants, backed by the New Civil Liberties Alliance (NCLA). It asks the Court to take up Choice Refrigerants v. EPA, a dispute that could become something bigger than refrigerants. It is shaping up as a stress test of the nondelegation doctrine, the long neglected principle that Congress cannot hand its legislative power to the executive branch.

What the case is about
The immediate fight is technical, but the stakes are not. Under the American Innovation and Manufacturing Act of 2020, Congress created a system of “allowances” that determines who gets to produce or import hydrofluorocarbons. The petitioners argue that the statute gives EPA sweeping control over a valuable marketplace without telling the agency how to make the central allocation decision.
NCLA’s filing focuses on one figure that should make any civics student sit up: the statute, they say, provides no meaningful direction for how EPA must allocate 98% of the allowances in this economically significant market.
When Congress writes a program like this, the question is not whether agencies should administer it. They should. The question is whether Congress supplied the governing rule, or merely built a policy vending machine and told an agency to pick whatever snacks it wants.
The constitutional flashpoint
Article I vests “all legislative Powers” in Congress. That does not mean Congress must write every line of every regulation. It does mean Congress is supposed to make the core policy choices and leave agencies to fill in the details.
For most of the modern era, courts have policed that boundary using a forgiving standard: if Congress gives an agency an “intelligible principle,” the delegation usually survives. In practice, that phrase has often operated like a rubber stamp. A broad goal, a general purpose, a handful of factors, and suddenly the agency is driving.
This is why supporters of the petition are urging the Court to take the case now. Their point is simple: if a statute that leaves the central allocation decision largely open ended still counts as “guided,” then the guidance requirement is not doing much guiding.
Why states are lining up
One of the striking features of this push is how many state governments have joined in urging review. A coalition led by West Virginia and 20 other states argues that when Congress sheds legislative responsibility, it does not just offend constitutional theory. It damages federalism in the real world.
Here is how the states put it: “Congress harms our whole constitutional order when it divests itself of legislative power like this. Amici States in turn suffer real harms; they lose their ability to regulate their own citizens in areas of traditional concern and shed their signature character as ‘laboratories of democracy.’”
That quote gets at an underappreciated point. Delegation does not merely shift power from Congress to agencies. It can also shift power from states to the federal bureaucracy, because broad federal regulatory programs tend to crowd out local problem-solving. The states’ complaint is not only “we disagree with EPA.” It is “we disagree with a system that lets Congress avoid making clear decisions that voters can reward or punish.”
When vagueness helps
Supporters of review describe a familiar cycle: Congress writes a statute with big aspirations and mushy commands. Courts then strain to find a limiting principle in the text, the structure, or even the legislative backstory. The agency ends up effectively determining what the law means in practice.
One brief warns against courts “saving” a statute by manufacturing constraints that Congress itself did not adopt. Mountain States Legal Foundation frames the duty bluntly: “When a lower court encounters a statute that transfers massive regulatory power without any guiding standard, the court’s job is to recognize the constitutional defect—not to paper over it.”
If you are wondering why this matters, ask yourself a basic accountability question: Who should have to vote for the painful tradeoffs? The people who run for office, or the people who write rules?
The Etch A Sketch problem
Even if you like a particular policy outcome today, delegation creates a legal climate that can flip tomorrow. If the statute is vague enough, a new administration can read the same law differently and move the market in a new direction without Congress passing a single new sentence.
Cato Institute captures that instability with a metaphor that hits home for anyone who has watched regulatory priorities change with election cycles: “Regulated parties like Choice will be left to deal with the consequences of an Etch A Sketch legal landscape.”
In other words, the law stops looking like law. It starts looking like management.
The D.C. Circuit and silence
A key point in the dispute is what to do with statutory silence. One side says silence means Congress did not set a rule. The other side says silence can be read as an invitation to borrow a rule from elsewhere.
Southeastern Legal Foundation summarizes the conflict this way: “Obviously, one plausible construction of the AIM Act’s silence is that it is silent as to how the EPA was to distribute allowances. The D.C. Circuit concluded that a second plausible construction is that the AIM Act directs that allowances be distributed in the same way as the Clean Air Act. But the text itself contains no evidence of this idea and contains much evidence of its opposite.”
This is the kind of interpretive choice that sounds academic until you remember what it does in practice. If a court can treat silence as permission to import standards from other statutes, Congress can be even less explicit in the next bill. The hard vote becomes optional.
What a fix could be
Supporters are not all asking the Court to do the same thing. Some want the justices to strengthen the existing intelligible-principle test. Others want a replacement with sharper teeth. Either way, the destination is similar: a rule that forces Congress to speak clearly when it hands an agency authority to reshape an industry.
Americans for Prosperity Foundation attacks the AIM Act program in structural terms, calling it a “cap-and-trade scheme”
that “runs roughshod over the Constitution’s structural guardrails, granting EPA untrammeled power to reshape a multi-billion-dollar industry to achieve whatever policy aims it may conjure.”
Strip away the rhetoric and the constitutional claim is straightforward: when an agency is effectively deciding the central policy question, it is doing legislative work. And legislative work belongs to the branch that must answer to voters.
Why this lands now
The campaign for Supreme Court review is unusually broad. According to NCLA, the Court has been urged to take the case through seven amicus briefs filed by a mix of public-interest organizations, legal groups, and policy advocates.
NCLA and Choice Refrigerants have also been joined at this stage by acclaimed Supreme Court litigators Erin Murphy and Paul Clement as co-counsel, underscoring how seriously they are treating the petition and how high they think the doctrinal stakes are.
NCLA General Counsel Zhonette Brown summarizes the pitch to the justices this way: “There is near universal agreement among objective scholars that the federal courts’ current doctrine fails to keep legislative power limited to the legislative branch. We thank each of the amici for helping to highlight that the Choice case presents the ideal vehicle for the Supreme Court to make an overdue course correction.”
“Course correction” is a polite phrase for a very impolite implication: Congress has gotten comfortable outsourcing the most controversial decisions, and the courts have been too willing to let it happen.
The question that remains
The nondelegation doctrine is often treated as a relic, a dusty warning label on the administrative state. But it is really a democratic principle. Laws are supposed to be made through bicameralism and presentment, with signatures and votes that can be traced to human beings.
So here is the question I would have asked my civics classes, and the question this case forces on the Court: when Congress creates a market-moving regulatory regime and gives an agency broad control over who wins and who loses, is that “administration,” or is that legislation with a different name?
If the Supreme Court takes Choice Refrigerants v. EPA, it will not just be deciding how refrigerant allowances are allocated. It will be deciding whether the Constitution’s separation of powers still requires Congress to do what we elect it to do: make the big choices in public, on the record, and with a clear vote.
