Legal Expert Says New Supreme Court Brief Could Be Turning Point for Second Amendment Case

Attorney Mark W. Smith, host of The Four Boxes Diner, opens his latest video with what he calls “major breaking news.”

He says the Second Amendment Foundation (SAF) has just filed a reply brief urging the U.S. Supreme Court to take up a young-adult Second Amendment case.

Smith frames the question cleanly. Does the Second Amendment protect 18–20-year-old adults?

He answers it plainly from the start. “Yes,” he says. But the real fight is whether the justices will grant cert now.

This is a procedural battle with huge consequences. And Smith argues the briefing from SAF makes the case compelling.

The Case Smith Says SCOTUS Should Hear

Smith identifies the docket: West Virginia Citizens Defense League v. ATF. The challenge targets a federal law that blocks 18–20-year-olds from purchasing handguns from FFLs.

He says this isn’t a state-by-state question. It’s a nationwide statute, and that’s exactly why consistency matters.

According to Smith, the Fourth Circuit is in the mix here. He notes the case is coming out of that appellate pipeline and now sits at the Supreme Court’s door.

The core claim is straightforward. Smith says the sale ban is unconstitutional under the Second Amendment and should fall.

Why Timing Is Everything

Smith highlights an unusual twist. He says the Solicitor General’s office – John Sauer, under the Trump administration – has asked the Court to hold off.

Not to deny. Just to wait, because the Court already granted review in two other 2A cases this term.

Smith names them. He points to Wolford (Hawaii’s “default no-carry” or “vampire rule”) and Hemani (the 922(g)(3) marijuana-and-guns case).

The government’s message, as Smith summarizes it, is procedural. Decide those two first; send this one back for reconsideration later.

Smith’s critique is crisp. He says delay is denial for this specific class of plaintiffs.

The Five Reasons Smith Says SAF Gave SCOTUS

Smith praises the SAF reply brief for doing “a very nice job” laying out five reasons to grant cert now. He runs through the essence of those points in short, sharp strokes.

First, the split is real. Smith says the federal courts of appeals are divided on whether 18–20-year-olds are protected under the Second Amendment.

Second, this is an ideal vehicle. He emphasizes SAF’s assurance that the association has standing and the case poses no mootness risk as a vehicle because the organization can continue to identify affected members.

Third, the government didn’t defend the merits. Smith notes the government’s stance is timing, not substance – “don’t take it now” – which, he argues, leaves the underlying constitutional conflict unaddressed.

Fourth, uniformity matters. He says national law should not operate one way in Texas, Louisiana, and Mississippi (the Fifth Circuit) and another way elsewhere.

Fifth, the young-adult window is short. Smith argues that aging out at 21 creates a uniquely urgent harm that can’t be brushed aside with a yearlong pause.

He calls these arguments “powerful.” And he thinks they match what the Court typically looks for when a federal statute is being applied differently across jurisdictions.

Two 2A Cases Already on the Docket

Smith recaps the two granted cases to explain the government’s “wait” posture. Wolford asks whether Hawaii can make most privately owned, publicly open places off-limits by default, even to permit holders.

He uses the “vampire rule” to make it memorable. No entry unless invited.

Then Hemani, which tackles 18 U.S.C. § 922(g)(3). Smith frames it as whether users of marijuana can be barred from gun possession consistent with Bruen.

His point is not to relitigate those controversies. It’s to show that multiple constitutional cases in one term is normal, and the Court need not stop at two.

Smith says the Supreme Court has often taken three or more cases in a single term on other constitutional amendments. So, in his view, there’s no institutional reason to limit the Second Amendment to a quota.

The Uniformity Problem Smith Flags

Smith’s most practical argument lands here. He says the Department of Justice is not enforcing the handgun-purchase restriction for 18–20-year-olds in the Fifth Circuit because of appellate rulings there.

But in other circuits, he says the federal government is enforcing the same statute. That yields a split legal regime under one national law.

Smith calls that untenable. And he says the Supreme Court traditionally steps in precisely to fix that national inconsistency.

He quotes the SAF reply brief on this point with approval. Uniform interpretation of federal statutes is one of the Court’s highest priorities.

The “Aging Out” Clock Is Ticking

Smith spotlights the mootness trap. For a 19-year-old litigant, a two-year pause isn’t academic – it’s a total loss of the right during the only years at issue.

Once you hit 21, he says, you’re beyond the law’s reach. The case risks becoming moot as to you, and the past deprivation is effectively irreparable.

That’s why, in Smith’s view, the Court should grant cert now. He argues it’s not fair to tell this cohort to “wait” when waiting erases the injury.

Here’s where I agree with Mark W. Smith. If there is a clean circuit split over a federal statute, and if the government is enforcing the law differently across the country, the Supreme Court’s institutional role gets triggered.

Uniformity isn’t a luxury. It’s a bedrock function of a national high court.

I also think the “aging out” factor is unusually compelling. Few constitutional disputes revolve around a three-year window where delay erases the harm for the very people bringing the claim.

If the Court wants to clarify Bruen’s reach in a discrete, recurring setting, this is a strong candidate.

And it won’t get easier with time. The same cycle repeats every year with a new class of 18-year-olds.

Where Smith Thinks This Could Go

Smith is candid that SCOTUS could go either way. He hopes for a grant, especially to settle the young-adult question once and for all.

He argues that 18–20-year-olds are indeed part of “the people” protected by the Second Amendment. And he views the sale restriction as constitutionally flawed under Bruen’s text-and-history test.

Even if the Court keeps Wolford and Hemani on track, Smith says it should add this case. He notes other amendments routinely see multiple cases per term.

His closing note is optimistic. If the Court takes this one, he believes pro-2A arguments will prevail.

Even outside the gun context, Smith’s uniformity point resonates. When the same federal law produces different rights based on your address, confidence in the legal system suffers.

This is exactly the kind of problem the Supreme Court is built to resolve. Not to pick sides prematurely, but to pick one national rule.

If Smith’s read of the SAF brief is right, the Court has a neat opportunity. It can clarify young-adult rights, standardize enforcement, and lower the temperature by giving everyone a clear answer.

In a year with multiple high-impact 2A cases already on deck, taking one more would not be unusual. It would be responsible.
