- Describe the constitutional-carry movement and analyse Bruen's history-and-tradition test, including its 2026 application in Wolford v. Lopez
Federalism shapes who regulates firearms
The Constitution grants Congress enumerated powers, including authority to regulate interstate commerce, while states retain broad police powers over health and safety. A federal firearms law may rely on a constitutional power such as the Commerce Clause; whether a particular law fits that power depends on its text, context and relevant precedent. The Commerce Clause is not a general statement that Congress may regulate anything related to public safety.
The Supremacy Clause makes valid federal law supreme over conflicting state law. Pre-emption applies when Congress has validly acted and federal and state rules conflict or Congress has displaced state regulation; the existence of federal law does not automatically erase every state rule in the same area. Analyse whether the federal rule is constitutional, what it covers and whether the two requirements can operate together.
In McDonald v. Chicago (2010), the Supreme Court held that the Second Amendment applies to state and local governments through the Fourteenth Amendment. This is selective incorporation: a particular Bill of Rights protection is applied to the states through Fourteenth Amendment doctrine. It is not total incorporation of every Bill of Rights provision all at once.
Bruen requires text-and-history analysis; later cases apply it
New York State Rifle & Pistol Association v. Bruen (2022) struck down New York's discretionary “proper cause” requirement for a public-carry licence. It set out a framework in which courts first ask whether the Second Amendment's text covers the conduct; if so, the government must show that the regulation is consistent with the Nation's historical tradition of firearm regulation. The Court rejected the former two-step approach that balanced the right against government interests using means-end scrutiny. A historical analogy must be reasoned, not a superficial search for an identical old law.
In 2026, Wolford v. Lopez applied this approach to Hawaii's default rule for licensed permit-holders carrying on private property open to the public without express permission. The Court held the challenged law violated the Second and Fourteenth Amendments on the record before it. The opinion addresses a particular default rule; it does not remove a property owner's right to exclude people or establish that every firearm regulation is unconstitutional. Separate opinions debated how to identify protected conduct and historical analogues, so learners should distinguish the holding from disputed reasoning.
The constitutional-carry movement supports allowing some eligible people to carry firearms in public without first obtaining a separate permit. States define eligibility and restrictions differently, and permitless carry does not mean “no gun laws.” A policy may still face constitutional analysis; neither a state's label nor the presence or absence of a permit alone resolves the issue.

Pause and explain
What does Bruen require after the Second Amendment's text covers the conduct?
Worked example
A state changes its public-carry rule from allowing licensed carry on private property open to the public unless the owner objects to requiring the owner's express permission. Explain the constitutional questions and identify a relevant 2026 case without claiming owners lose their right to exclude.
Show the worked solution
- Separate the individual carry right from a property owner's authority to exclude.
- Use the Second and Fourteenth Amendments and the Bruen historical framework.
- Describe Wolford v. Lopez as a decision about Hawaii's challenged default rule and the record before the Court.
Answer The rule raises a Second Amendment question because it regulates public carry and, under McDonald, the right applies to states through the Fourteenth Amendment. Bruen requires text-and-history analysis rather than ordinary means-end balancing. Wolford v. Lopez (2026) held Hawaii's challenged default rule unconstitutional as applied to licensed permit-holders carrying on property open to the public without express permission. The holding does not eliminate an owner's right to exclude; it addresses which default applied absent express owner consent under the law before the Court.

Test this topic →From guided practice to a new situation
Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: A federal law regulates a firearm transaction that crosses state lines, while a state imposes an additional licensing condition. Explain which clauses could matter and why the two rules are not automatically inconsistent.
Give me a hint
Identify the possible federal power and federal supremacy, then check whether the requirements actually conflict.
Compare my reasoning
- The Commerce Clause may support federal regulation of interstate transactions, subject to constitutional limits.
- The Supremacy Clause governs conflicts with valid federal law.
- Check the text and scope of both rules; if a person can satisfy both, they may operate together.
The Commerce Clause may supply Congress with authority over an interstate transaction, but the federal rule still has to fit that power. The Supremacy Clause controls if a valid federal rule conflicts with state law or displaces it. If the person can comply with both federal and state requirements and Congress has not displaced the state rule, the two may operate together. The clauses identify questions to test; they do not answer the hypothetical without the statutes' details.
Look for these in your work
- Recognises the possible commerce basis
- Explains when supremacy matters
- Checks for actual conflict or displacement
Independent: A state bans a type of public carry. Under Bruen, outline the analysis a court would use and explain why an ordinary public-safety balancing test is insufficient.
Give me a hint
Start with the constitutional text and then identify the government's historical-analogue burden.
Compare my reasoning
- Ask whether the Second Amendment's text covers the conduct at issue.
- If it does, the government must show the regulation fits the historical tradition of firearm regulation.
- Do not substitute a free-form balance of costs and benefits for the Bruen framework; assess the claimed analogue carefully.
A court first asks whether the Second Amendment's text covers the conduct. If it does, Bruen requires the government to show that the restriction is consistent with the Nation's historical tradition of firearm regulation. An ordinary means-end test that balances a public-safety interest against a burden on the right is not the framework Bruen adopted. The application depends on the law, conduct and historical evidence.
Look for these in your work
- States the text question
- States the history-and-tradition burden
- Distinguishes Bruen from means-end balancing
Transfer: A student says Wolford v. Lopez means every business must allow concealed carry and all permit requirements are invalid. Correct the claim and explain what the case actually decided.
Give me a hint
Keep the holding within the law, parties and issue the Court considered.
Compare my reasoning
- Identify Hawaii's default rule for licensed permit-holders on private property open to the public.
- State that the Court held the challenged law violated the Second and Fourteenth Amendments.
- Preserve an owner's authority to exclude and avoid generalising to all permit requirements or locations.
Wolford v. Lopez (2026) held that Hawaii's challenged law, which required express property-owner permission for licensed permit-holders carrying on private property open to the public, violated the Second and Fourteenth Amendments. It did not require every business to allow firearms: owners retain a right to exclude. Nor did it invalidate all permit requirements or every restriction in all settings. Apply the holding to its facts and distinguish broader questions the case did not decide.
Look for these in your work
- Identifies the specific Hawaii default rule
- States the holding accurately
- Rejects overbroad claims about owners and permits
Common mistakes
- Treating the Commerce Clause as unlimited federal public-safety authority
- Assuming every federal law displaces all state firearms rules
- Calling incorporation of the Second Amendment against states total incorporation
- Reducing Bruen to a general balancing test or treating any historical difference as irrelevant
- Claiming Bruen makes every modern firearm regulation unconstitutional
- Reading Wolford as eliminating private property owners' rights to exclude
- Treating constitutional carry as carry without eligibility rules or other restrictions
What can you explain now?
What does Bruen require after the Second Amendment's text covers the conduct?
Compare with the explanation
The government must show the challenged regulation is consistent with the Nation's historical tradition of firearm regulation
Bruen calls for a text-and-history framework, not ordinary means-end balancing; the historical comparison must be relevant and reasoned.
