Why these cases matter to you
Every state page on this site, every reciprocity rule, every "sensitive location" restriction you've read about — all of it sits downstream of three Supreme Court decisions. Heller established that the Second Amendment protects an individual's right to a gun, not just a militia's. McDonald made that right apply to state and local governments, not just the federal government. Bruen extended it from your home onto the public street — and rewrote the legal test courts use to decide if any gun law is constitutional at all.
District of Columbia v. Heller
Washington, D.C. had banned handgun possession in the home outright, and required any lawfully-owned long gun to be kept unloaded and either disassembled or trigger-locked — making it essentially impossible to use a firearm for self-defense even where it was technically legal to own one. Dick Heller, a D.C. special police officer who carried a gun on duty but couldn't legally keep one at home, sued.
What it didn't do: Heller was explicit that the right "is not unlimited" — the opinion specifically preserved laws barring gun possession by felons and the mentally ill, restrictions on carrying in "sensitive places" like schools and government buildings, and conditions on commercial firearm sales. It also didn't address whether this right applied beyond the home, or whether it applied to state governments at all — D.C. is a federal enclave, not a state, so that second question stayed open.
McDonald v. City of Chicago
Heller answered the question for the federal government and D.C. — but Chicago had a handgun ban just as strict, and Chicago argued the Second Amendment simply didn't apply to cities and states at all. Otis McDonald, a 76-year-old retired maintenance engineer who'd been burglarized multiple times in his Chicago neighborhood, sued alongside the NRA to find out.
This is a narrower-sounding holding than it might seem, but it's the one that made Heller actually matter nationwide. Without McDonald, a city like Chicago could have kept its handgun ban in place indefinitely, since Heller technically only bound the federal government. Justice Thomas agreed with the outcome but wrote separately, arguing the right should flow from the Fourteenth Amendment's Privileges or Immunities Clause instead of Due Process — a legal theory question that mattered to scholars more than to anyone trying to keep a handgun at home, but one that still gets debated in later cases.
New York State Rifle & Pistol Association v. Bruen
New York's century-old Sullivan Act required anyone wanting a concealed carry license to prove "proper cause" — a special need for self-protection beyond what the general public faced. In practice, this meant local licensing officials had broad discretion to simply deny ordinary applicants. Robert Nash and Brandon Koch, both legally eligible and background-checked, were denied unrestricted licenses anyway. They sued, with the New York State Rifle & Pistol Association backing the case.
Bruen did something bigger than resolve one New York law, though: it threw out the legal test most federal courts had been using for 14 years to decide any Second Amendment case (a two-step balancing test weighing the government's interest against the burden on gun rights). In its place, the Court established the "text, history, and tradition" test: if the plain text of the Second Amendment covers your conduct, the government can only justify restricting it by showing the restriction is consistent with how firearms were historically regulated in America, not by arguing the restriction serves a good modern policy goal.
This single change reshaped gun law litigation nationwide. Within weeks, California, Hawaii, New Jersey, and other "may-issue" states directed officials to stop requiring proper-cause showings. New York itself responded by passing the Concealed Carry Improvement Act (CCIA) — replacing "proper cause" with new training and background requirements, while creating one of the most extensive "sensitive places" lists in the country. That same pattern — shall-issue now required, paired with an expanded list of places where carry is newly restricted — played out in several other previously-restrictive states, and is the direct reason several state pages on this site describe "significant restrictions remain post-Bruen."
The timeline at a glance
Five decisions, eighteen years. Each one narrowed the question the next would have to answer — from whether the Second Amendment protects an individual right at all, to where that right can actually be exercised.

United States v. Rahimi
Decided June 21, 2024 · 8–1 · Chief Justice Roberts writing
Two years after Bruen, the Court took up the first case testing how far its new history-based framework actually reached. Zackey Rahimi was subject to a domestic violence restraining order and challenged the federal statute barring him from possessing firearms, arguing no sufficiently similar historical law existed.
The Court disagreed, nearly unanimously. It held that a person found by a court to pose a credible threat to another's physical safety may be temporarily disarmed consistent with the Second Amendment. Historical surety and “going armed” laws supplied a close enough principle — the analogue need not be a twin.
Why it matters to carry law: Rahimi is the decision that stopped Bruen from being read as an absolute. It confirmed the right is subject to limits, and it disciplined how lower courts run the historical test — they are looking for a matching principle, not an identical statute. It also tightened the standard for facial challenges, which is why later opinions spend so much time separating facial from as-applied attacks.
Wolford v. Lopez
Decided June 25, 2026 · 6–3 · Justice Alito writing
The most consequential carry decision since Bruen, and the one most likely to affect where you can actually carry today.
After Bruen forced states to abandon discretionary permitting, several responded by restricting locations instead. Hawaii's Act 52 flipped the traditional default on private property: rather than a licence holder being free to enter a shop unless told otherwise, they needed the owner's express permission first. Because almost no business posts a sign either way, challengers argued the rule barred carry on roughly 96% of publicly accessible land in the state. Critics nicknamed it the “vampire rule” — you may not enter unless invited.
The Court struck it down. A law prohibiting licensed carry on private property open to the public without the owner's express authorization violates the Second and Fourteenth Amendments. The majority found Hawaii's historical analogues unpersuasive — the early statutes it relied on targeted unauthorised hunting and trespass on closed land, not armed self-defence in shops — and pointedly rejected reliance on a Reconstruction-era Black Code provision, saying its pedigree meant it could not be taken seriously as evidence of the original understanding.
Justice Alito described the practical effect as staggering: an ordinary run of errands past a gas station, a grocery store and a dry cleaner could make a licensed carrier a criminal several times over without any intent to break the law.
Why it matters to carry law: the decision reaches well beyond Hawaii. Four other states — California, Maryland, New York and New Jersey — had adopted materially similar default rules. New York's had already been struck down by the Second Circuit in Christian v. James a month earlier; California's is foreclosed; New Jersey's is before the Third Circuit sitting en banc. If you have read older guidance telling you to look for a posted sign before entering a business, Wolford is why that advice is now out of date in most of those states.
The other sensitive-place categories — parks, transit, bars, schools — were not before the Court and remain in force wherever they have survived their own challenges.
📍 What this means for the carry law you're looking at today
Every "shall-issue" state you see on this site exists in roughly its current form because of Bruen — discretionary "may-issue" denial is no longer a constitutionally available option anywhere in the country. But Bruen didn't deregulate everything: it explicitly preserved the idea of "sensitive places" from Heller, and states have spent the years since arguing — often in ongoing litigation — about exactly how far that category can stretch. That's why states like New York, New Jersey, California, and Hawaii still show up as "highly regulated" on this site's map even after Bruen: the discretionary licensing is gone, but expansive sensitive-places lists took its place, and courts are still actively deciding which of those restrictions survive the "text, history, and tradition" test.
Frequently asked questions
Did Bruen make concealed carry legal everywhere?
No. Bruen struck down discretionary "may-issue" licensing and established that states must use an objective process for issuing permits — but states can still require a permit at all (shall-issue), and can still restrict carry in "sensitive places." It didn't create permitless carry anywhere; that's a separate, state-by-state legislative choice unrelated to this case.
Is the "text, history, and tradition" test the same in every court?
In principle, yes — it's binding on all federal and state courts. In practice, applying it has been contentious: courts have reached different conclusions about what counts as a sufficiently similar historical analogue for a modern law, leading to a wave of inconsistent lower-court rulings on issues like "sensitive places," magazine limits, and who can be barred from possessing firearms. Expect continued Supreme Court involvement to resolve these splits.
Does Heller mean any law restricting guns is unconstitutional?
No — Heller explicitly said the opposite. The majority opinion specifically preserved laws barring possession by felons and the mentally ill, restrictions in sensitive places, and conditions on commercial sales, describing the right as "not unlimited."
What happened after Bruen — is the law still changing?
Yes, significantly. Lower courts are still working through what counts as a constitutionally permissible "sensitive place" and what historical analogues are close enough to justify modern restrictions. The Supreme Court has continued to weigh in on related questions since Bruen (for example, addressing federal firearms restrictions for those under domestic violence protective orders in a 2024 case). This is an active, unsettled area of law — treat any specific claim about "what Bruen requires" for a novel situation as provisional until a court has actually ruled on it.
