Supreme Court rules in United States v. Hemani — what it means for Illinois

The Supreme Court handed down a unanimous decision on June 18, 2026 in United States v. Hemani, striking down the federal government's attempt to permanently disarm Americans simply because they use marijuana. The ruling dismantles the broad application of 18 U.S.C. § 922(g)(3) — the federal statute that bans gun ownership by anyone who is an "unlawful user" of a controlled substance — and it does so on straightforwardly Bruen-based grounds: the government could not point to a historical tradition of disarming people for casual drug use.

This matters in Illinois. Not just as a general Second Amendment win, but because the legal reasoning the Court used maps directly onto arguments we've been making in our own case — and onto the broader PICA litigation playing out right now in the Seventh Circuit.

What the Court Actually Decided in Hemani

Justice Gorsuch wrote for the majority. Justice Thomas filed a concurrence that, by all accounts, pushed the reasoning even further. The core holding is this: the federal government cannot impose a categorical, lifetime firearms ban on a person solely because of their status as a marijuana user. The government must show that the specific prohibition is consistent with the nation's historical tradition of firearms regulation. It couldn't do that here.

The Second Amendment Foundation, which filed an amicus brief in Hemani, described the ruling as a significant victory and noted that the historical-tradition test the Court applied came directly from Bruen. That test is the same framework we've been invoking to challenge PICA since day one.

The practical takeaway for the individual: being a casual marijuana user does not, standing alone, cost you your Second Amendment rights under federal law. The ruling does not legalize marijuana, and it does not mean a prohibited person becomes unprihibited. What it means is that the government cannot stretch a status-based categorical ban beyond what history and tradition actually support.

The Bruen Thread Running Through Every Case

Here's why I'm watching Hemani closely even though it has nothing to do with rifles or magazine capacity on its face. The Court just reaffirmed, unanimously, that historical tradition is the binding test — and that the government loses when it can't meet that burden.

Illinois' PICA ban has the exact same problem. The State cannot point to a founding-era tradition of banning the most commonly owned rifles in America. They've tried. In our briefing, and in Barnett v. Raoul, they've offered colonial-era analogies that don't hold up under any serious historical scrutiny. Every time the Supreme Court applies the Bruen framework rigorously — as it just did in Hemani — it narrows the State's already thin arguments.

A unanimous Supreme Court applying Bruen to strike down a federal gun ban is not background noise. It's a direct signal to every lower court, including the Seventh Circuit, about how the analysis is supposed to work.

The Seventh Circuit is still sitting on our case. The en banc court heard arguments. We've been waiting. Every ruling that comes down from above — whether it's the Fifth Circuit's approach to common-use analysis, the Second Circuit's private-property decision, or now this — shapes the environment in which that eventual ruling lands. Judges read the same opinions everyone else does.

Illinois Gun Owners and Federal Prohibition Status

There's a practical question I want to address directly, because I know some customers are going to ask about it. Illinois has its own FOID system, and the state takes a hard line on anyone with a disqualifying record. Federal law and state law operate on parallel tracks here.

Hemani addresses the federal prohibition under 922(g)(3) specifically. It does not automatically resolve every state-level question about marijuana and firearms, including Illinois' own rules. If you are a medical cannabis cardholder in Illinois, you already know the state has taken the position that cardholders cannot hold a FOID card — that separate fight is still ongoing in Illinois courts. Hemani strengthens the constitutional argument against those restrictions, but it does not flip that switch today.

What it does do is give attorneys a sharper tool. The historical-tradition test now has another unanimous application behind it. Anyone challenging a status-based firearms prohibition — whether federal or state — has a stronger framework to work with.

If you have questions about your specific situation, talk to a licensed attorney in Illinois who knows firearms law. That's not a dodge — it's just the right advice when individual circumstances vary this much.

Where Things Stand as of June 2026

To keep everything in one place:

• United States v. Hemani — decided June 18, 2026. Federal marijuana gun ban narrowed under Bruen's historical-tradition test. Unanimous.
• Bevis v. City of Naperville / Barnett v. Raoul — en banc Seventh Circuit has heard arguments. No ruling as of this writing. The DOJ's amicus brief on our side and Harmeet Dhillon's argument remain part of the record.
• PICA — still in effect in Illinois pending the Seventh Circuit's decision. Nothing about Hemani changes the law on the ground in Illinois today, but it reinforces the constitutional direction of travel.
• Virginia assault weapons ban — a separate but parallel fight. GOA and SAF are both engaged. Worth watching for how courts outside the Seventh Circuit handle common-use and historical-tradition analysis on rifle bans specifically.

I've covered several of the upstream rulings that have been building toward this moment over at the Law Weapons blog — including the Fifth Circuit's common-use analysis and the DOJ's entry into our case. The picture has been developing for months.

A unanimous Supreme Court ruling that the government must satisfy a historical-tradition test before stripping someone's gun rights doesn't happen in a vacuum. That logic flows downstream. The Seventh Circuit knows it. The State of Illinois knows it. We're going to keep making sure everyone else knows it too.

We didn't start this fight, but we plan to finish it.
