Constitutional Law Essentials — Bar Exam

MBE federalism questions usually hide the real issue inside a fact pattern about something else, so your first move is always identify which side is acting. If Congress acts, ask whether an enumerated power authorizes it (the answer can’t be “general welfare” as a standalone power — that phrase only states the purpose of the taxing-and-spending power, not a freestanding right to regulate). If a state acts, presume the police power supplies authority and hunt for a federal limit: preemption, the dormant Commerce Clause, or an individual right. The answer usually turns on a default rule — states get the benefit of the doubt on power, the federal government on supremacy.

The classic trap conflates commerce power (Congress’s affirmative authority to regulate) with anti-commandeering (a structural limit barring Congress from ordering states to legislate or enforce). Congress may reach states through laws of general applicability and may attach strings to spending (the South Dakota v. Dole conditions), but it may not commandeer. Don’t confuse preemption (federal law displacing state law) with commandeering (federal law conscripting state machinery to do federal work).

On the MBE, the affirmative-power “tell” is a federal statute reaching some local activity: look first for aggregation — Congress may regulate purely intrastate, even non-commercial conduct if, taken in the aggregate, it substantially affects interstate commerce (Wickard v. Filburn, homegrown wheat; Gonzales v. Raich, homegrown marijuana). The trap is the answer insisting the activity itself cross state lines — it need not. But the NFIB v. Sebelius line limits this: Congress may regulate existing economic activity, not compel inactivity (it cannot force you to buy insurance), and the substantial-effects category cannot reach noneconomic activity by stacking attenuated effects.

For dormant Commerce Clause patterns, the hinge is discriminatory versus merely incidental burden: facial discrimination is virtually per se invalid (survives only if narrowly tailored to a legitimate local end with no nondiscriminatory alternative), while an evenhanded law gets Pike balancing (burden weighed against local benefits). Two escape hatches students forget: the market-participant exception (a state buying or selling may favor its own) and congressional consent, which cures an otherwise-invalid burden. Don’t confuse this state-restraining doctrine with anti-commandeering or Eleventh Amendment immunity from the sovereignty material.

The MBE almost always tests this in two moves: identify the classification on the face of the statute, then apply the matching tier. The classic trap is a facially neutral law: a statute that says nothing about race still gets only rational basis unless the facts show both discriminatory intent and discriminatory effect (Washington v. Davis); disparate impact alone is a wrong-answer magnet. Watch for the affirmative-action fact pattern — race-based remedies still draw strict scrutiny (Adarand), and after SFFA v. Harvard (2023) race may no longer be used as an admissions factor, so distrust any choice approving it (older banks still cite Grutter as good law).

Don’t confuse equal protection with substantive due process: due process attacks a law burdening everyone’s fundamental right, while equal protection attacks a law treating classes differently. A clean tell — if only some people are denied a right, run equal protection; if everyone is, run due process. Alienage is the sleeper: state alienage classifications get strict scrutiny, but federal ones get only rational basis (immigration/naturalization power).

The MBE’s favorite move is making you classify the regulation before you pick a tier. First ask whether the speech falls in an unprotected category; if not, ask whether the law is content-based (targets subject matter or viewpoint → strict scrutiny, Reed v. Town of Gilbert) or content-neutral. The classic trap: a facially neutral law that is really viewpoint discrimination is still content-based and gets strict scrutiny. In a public forum, watch the three-part time/place/manner test and its ample alternative channels prong — answers omitting that prong are wrong. For incitement, demand Brandenburg’s imminent lawless action (directed to and likely to produce it), not mere advocacy.

Don’t confuse this forum analysis with the Establishment Clause’s history-and-tradition inquiry (post-Kennedy v. Bremerton, the Lemon test is gone), or with substantive due process strict scrutiny — same tier name, different doctrine. Another trap: prior restraints and licensing schemes are tested separately from after-the-fact punishment, and a permit scheme needs narrow, objective, definite standards cabining official discretion. Memory hook: content-based = strict, content-neutral or conduct = intermediate.

The MBE tests this by burying the classification in the facts and daring you to skip a step: first identify the trait, then pick the tier, then apply it. The favorite trap is alienage, which splits — state and local discrimination against lawful aliens is suspect (strict scrutiny), but the federal government gets near-rational-basis deference (immigration is a plenary federal power), and even a state may use rational basis under the political-function exception (police, teachers, jurors, voters). Watch facially neutral laws too: the answer hinges on discriminatory purpose, so a law that merely produces disparate impact gets only rational basis absent intent.

Don’t confuse the classification with the right. If the question turns on a fundamental right (voting, travel, privacy), that flows through liberty and substantive due process or equal protection’s fundamental-rights strand — not the suspect-class analysis (abortion left that set after Dobbs). And keep gender in the quasi-suspect lane: students reflexively upgrade sex to strict scrutiny, but it stays intermediate, now demanding an “exceedingly persuasive justification” after VMI.

On the MBE the tell is a plaintiff who is angry but not personally injured — a citizen suing over “illegal” government conduct is a generalized grievance and lacks standing, so the answer dismisses for want of a concrete, particularized stake (post-TransUnion, a bare statutory violation or risk of future harm won’t support damages). Watch redressability: even a real injury fails if the requested relief won’t fix it (suing the wrong defendant, or seeking a remedy the court can’t grant). The exam also tests third-party standing — normally barred, but allowed where the litigant has its own injury plus a close relationship and an obstacle to the right-holder asserting their own rights (doctor–patient, vendor–buyer). Associational standing needs members who would have standing, interests germane to the group’s purpose, and no required individual-member participation.

The classic trap confuses standing with mootness: standing is tested at the start of suit, but a once-live case can go moot later — unless it is capable of repetition yet evading review or the defendant merely voluntarily ceased the conduct. Don’t conflate standing’s injury inquiry with the merits — it is the threshold gate cleared before any federalism or free-speech argument is reached.

The MBE tells you which due process you’re in by the complaint: a plaintiff angry about how they were treated (no notice, no hearing) is procedural; one arguing the government cannot do this at all is substantive. The classic trap is a fact pattern that looks procedural — a license yanked, a benefit cut — where the call is really what process, not whether. Watch the threshold: procedural due process needs state action depriving life, liberty, or property, and “property” requires a legitimate entitlement (a statute or rule), not a unilateral hope (Board of Regents v. Roth). Negligent deprivations don’t trigger it (Daniels v. Williams).

Don’t conflate liberty with Equal Protection: due process attacks a burden on everyone, while equal protection attacks unequal treatment between groups — one statute can raise both, and Obergefell rests on both rails at once. Also, most economic and social legislation gets only rational basis under substantive due process; reserve strict scrutiny for fundamental rights (largely the unenumerated ones — privacy, marriage, travel). Memory hook: procedure = “how,” substance = “whether.”

The MBE tests privacy by handing you a state law touching an intimate-autonomy interest and forcing you to pick the tier of scrutiny first — the answer turns on whether the right is “fundamental.” If it is, strict scrutiny applies, the burden flips to the government, and the law usually falls; if not, rational basis controls and it survives. The recurring “tell” is a post-Dobbs fact pattern: abortion is now reviewed like ordinary social-and-economic regulation under a rational basis standard, so the right answer upholds the statute, not the one applying heightened review (some older banks still file abortion under privacy as a fundamental right).

The classic trap is confusing privacy with its neighbors. Liberty is the broader Due Process container, and it splits into procedural (what process is due) versus substantive (whether the deprivation is allowed at all) — privacy lives only on the substantive side. Equal Protection keys scrutiny to a classification, not to a fundamental right; don’t grab intermediate review (the gender/legitimacy tier) for a substantive-due-process privacy claim.

Expect a fact pattern where Congress directly orders state officials to administer a federal program — collect background-check data, enforce a regulatory scheme, or keep a law on the books. The tell is compulsion of the state itself: that triggers anti-commandeering and the answer is unconstitutional. The trap is forgetting Congress’s two workarounds — conditional spending (money with strings that are unambiguous, related to the program, and not coercive) and generally applicable regulation hitting private parties and states alike (Reno v. Condon). Murphy v. NCAA (2018) extended the doctrine: Congress also cannot prohibit states from legislating, not just compel them.

Don’t confuse sovereignty with federalism (the broad structural division of power) or the Commerce Clause (the affirmative grant Congress over-reaches via Lopez/Morrison). Immunity traps: the Eleventh Amendment doesn’t reach suits against local governments and counties, but state court is no loophole — Alden v. Maine bars private damages suits against a nonconsenting state even there. Ex parte Young lets you sue the officer for prospective injunctive relief — never back-pay from the treasury (Edelman).

Bar questions hand you a government program touching religion — a school-voucher plan, a legislative prayer, a Ten Commandments monument, a tax exemption — and make you pick the controlling test. The tell is the type of activity: for public displays and ceremonies, the answer now turns on whether the practice fits a long historical tradition (Town of Greece, Kennedy v. Bremerton); for school funding reaching religious schools, the hinge is neutral, private choice (Zelman, Carson v. Makin), and excluding religious options solely because they’re religious violates Free Exercise. Watch for the rare direct denominational preference, which still draws strict scrutiny (Larson v. Valente).

The classic trap is reflexively applying Lemon’s three prongs — Kennedy says the Court has abandoned that framework, though some older question banks still grade it. Don’t confuse this with Free Speech: a religious group’s equal access to a public forum is a free-speech/viewpoint issue, not an establishment problem (and denying access is the constitutional violation). Memory hook: history over Lemon, choice over coercion.
