⚡ 10-Second Rule
A few deeply personal choices get maximum protection; every other law survives if any sensible reason supports it.
🧒 ELI-10 Scene
Nadia's apartment building has house rules. Most rules are fine if the landlord has any decent reason — quiet hours, no grills on balconies, park bikes in the rack. Nadia can grumble, but the rules stand. A few things are different. Whom Nadia marries. How she raises her son Theo. Whether Theo learns Spanish at home. Those choices sit in a locked box the landlord can barely touch. To reach into the box, the landlord needs a truly huge reason and no gentler way. For everything outside the box, almost any reason will do.
⚖️ Actual Rule
The Due Process Clauses of the Fifth and Fourteenth Amendments have a substantive component that protects certain fundamental rights from government interference regardless of the procedures used. Under Washington v. Glucksberg, 521 U.S. 702, 720–21 (1997), fundamental rights are those "deeply rooted in this Nation's history and tradition" and "implicit in the concept of ordered liberty, such that neither liberty nor justice would exist if they were sacrificed," and the asserted right must be given a "careful description." Laws burdening a fundamental right — marriage, procreation, contraception, child rearing and education, and family living arrangements — receive strict scrutiny (refusing unwanted medical treatment is a protected liberty interest under Cruzan v. Director, 497 U.S. 261 (1990), though the Court balanced rather than applied strict scrutiny): the government must show the law is narrowly tailored to serve a compelling interest. All other liberty interests, including economic regulation and business activity, receive rational basis review: the challenger must show the law is not rationally related to any conceivable legitimate government interest. See Williamson v. Lee Optical Co., 348 U.S. 483 (1955). The Fourteenth Amendment's Due Process Clause also incorporates nearly all Bill of Rights guarantees against the states — including the Second Amendment, McDonald v. City of Chicago, 561 U.S. 742 (2010) — with the main exceptions being the Fifth Amendment grand jury requirement and the Seventh Amendment civil jury right. In Dobbs v. Jackson Women's Health Organization, 597 U.S. 215 (2022), the Court held "Roe and Casey must be overruled": abortion is not a fundamental right, and abortion regulations are now reviewed under rational basis. The Dobbs majority stated its decision does not cast doubt on precedents concerning contraception, intimacy, or marriage. [NJ-VARIANT: flagged for future Eli Explains NJ Law module]
ELI-10 translation: locked-box choices need a huge government reason; everything else stands on almost any reason.
🔍 Ask These Questions
- Is the government limiting someone's liberty — a law or official act, not a private choice? (These rules only stop government players, not neighbors or bosses.)
- Describe the right carefully and narrowly — what exact choice is being blocked? (Name the exact thing, not a big fuzzy idea like "freedom.")
- Is the right fundamental — deeply rooted in history and tradition, like marriage, contraception, or raising your kids? (Is this choice in the locked box America has always protected?)
- If fundamental, apply strict scrutiny — the government must prove a compelling interest and narrow tailoring. (The government needs a giant reason and the gentlest possible tool.)
- If not fundamental — including economic rules and, after Dobbs, abortion — apply rational basis. (The challenger loses unless the law makes zero sense at all.)
- Check for a hidden incorporation issue — is a Bill of Rights guarantee being applied to a state? (Most of the first ten amendments bind states too, through this clause.)
⚠️ Bar Trap
Exam language: Examiners tempt you to apply heightened scrutiny to economic or business regulation because the law seems foolish, protectionist, or unfair — but Lochner-era review is dead, and rational basis is nearly always fatal to the challenger. The modern twin trap: treating abortion as a fundamental right; after Dobbs, abortion regulations get rational basis review, while contraception, marriage, and child-rearing precedents remain good law.
ELI-10: A silly business rule still wins in court; silly is allowed. And know today's locked box: abortion came out of it in 2022, but marriage, birth control, and parenting stayed in.
🧪 Question
A state statute requires anyone who braids hair for money to complete 1,200 hours of training at a licensed cosmetology school, at an average cost of $15,000. The mandatory curriculum devotes fewer than 40 hours to braiding. A braider who has practiced safely for ten years sued, alleging the statute deprives her of liberty in violation of the Due Process Clause of the Fourteenth Amendment. The legislature made no findings, but the state argues the requirement could promote sanitation and consumer protection.
What standard of review should the court apply, and who bears the burden?
(A) Strict scrutiny, with the state required to show the statute is narrowly tailored to a compelling interest. (B) Intermediate scrutiny, with the state required to show the statute is substantially related to an important interest. (C) Rational basis, with the braider required to show the statute is not rationally related to any conceivable legitimate interest. (D) Rational basis, with the state required to produce evidence of the statute's actual purpose and effectiveness.
Answer: (C). Pursuing an occupation is an economic liberty, not a fundamental right, so rational basis applies. The challenger bears the burden, and any conceivable legitimate purpose — even one the legislature never articulated — sustains the law.
💡 Why the Wrong Answers Are Wrong
- (A) treats occupational freedom as fundamental; economic liberties lost strict protection when the Lochner era ended.
- (B) imports intermediate scrutiny, which belongs to equal protection categories like gender, not substantive due process claims about economic regulation.
- (D) picks the right tier but flips the burden; under rational basis the government need not prove anything, and hypothetical purposes suffice.
- ELI-10: The misconception is thinking dumb laws are unconstitutional laws. Outside the locked box, the government wins even with a made-up-later reason.
