FE-1 Constitutional Law common mistakes
FE-1 Constitutional Law · Understand the traps and how to avoid them.
Applying the rational-basis label to a fundamental-right or suspect-classification problem because the word 'rational' appears in the fact pattern, instead of first identifying the right or classification at issue and selecting the matching tier of scrutiny.
Candidates memorize a three-tier table in the abstract and then pattern-match on surface vocabulary. Under time pressure, the tier is chosen before the interest is characterized, so the analysis is slotted into the wrong framework from the first sentence.
What to do instead
Before writing anything, answer two questions in the margin: (1) is a fundamental right, suspect class, or quasi-suspect class involved, and (2) is the classification facially neutral but discriminatory in effect? Only after those answers pick the tier. Practice by sorting a set of 20 short hypotheticals into tiers without writing any analysis.
Treating state action as satisfied whenever a private party's conduct has a public consequence, or as absent whenever the actor is nominally private, without testing the specific state-action doctrines.
The state-action requirement is taught early and then assumed rather than applied. Candidates conflate 'affected with a public interest' with state action and miss the entanglement, public-function, and encouragement tests that actually decide these questions.
What to do instead
Memorize a checklist of the recognized tests (public function, close nexus or entanglement, state encouragement or coercion, and the symbiotic-relationship formulation) and run every private-actor fact pattern through all of them. Note that mere licensing, regulation, or receipt of public funds is generally insufficient.
Conflating the Establishment Clause tests and applying the endorsement or coercion logic without stating which test governs and why, or reciting the Lemon factors as if they were the exclusive framework.
The doctrine has shifted over time, and outlines written at different moments give contradictory summaries. Candidates memorize one formulation and force it onto every religion question.
What to do instead
Build a short chronology of the governing formulations and the fact patterns each addressed, and practice stating expressly which test you are applying and what result it produces. Where the current doctrine is unsettled, say so and analyze under the leading alternatives rather than asserting a single rule.
Answering free-speech questions by asking only whether the speech is offensive or unpopular, rather than identifying the forum, the type of regulation (content-based versus content-neutral), and whether the speech falls into an unprotected category.
Public debate frames free-speech issues around offensiveness, so candidates import that framing. They skip the forum analysis, which is what actually determines the standard applied to time, place, and manner restrictions.
What to do instead
Use a fixed sequence: (1) is the speech protected at all (incitement, true threats, obscenity, fighting words, fraud); (2) what is the forum (traditional public, designated, nonpublic, or limited); (3) is the regulation content-based or content-neutral; (4) apply the corresponding standard. Drill the forum categories until they are automatic.
Treating all due-process guarantees as interchangeable, so a procedural due-process question is answered with substantive analysis, or a takings question is answered with procedural due-process reasoning.
The clauses share vocabulary and are often taught in one block. Candidates see 'deprivation' or 'property' and answer with whichever doctrine they reviewed most recently.
What to do instead
Classify each question first: is the claim that the government acted without adequate process, that it acted arbitrarily regardless of process, or that it took property for public use? Then apply the matching framework (Mathews balancing for procedure; fundamental-rights or rational-basis review for substance; the takings framework for physical invasion and regulatory takings).
Ignoring the Eleventh Amendment and sovereign immunity when a question involves suits against a state, and failing to distinguish suits against the state itself from suits against state officers for prospective relief.
Candidates focus on the merits of the underlying constitutional claim and treat immunity as an afterthought, missing that the same claim can be barred or permitted depending on the defendant and the relief sought.
What to do instead
For every suit against a state or state entity, run a separate immunity analysis: who is the defendant, is the relief damages or prospective injunctive relief, and has the state consented or Congress validly abrogated immunity? Memorize the officer-suit distinction and apply it explicitly in the answer.
Misapplying standing by finding injury from a generalized grievance, or by treating taxpayer status or ideological disagreement as sufficient injury in fact, and then skipping the causation and redressability elements.
Candidates stop after finding some harm and do not run the full three-element test. Generalized grievances feel like real injuries, so the exception swallows the rule.
What to do instead
Write out injury in fact, causation, and redressability for every standing question, and separately note the narrow taxpayer-standing exception and the limits on third-party standing. Practice identifying which element a given fact pattern is actually testing.
Treating Congress's enumerated powers as a general police power, or upholding a federal statute under the Commerce Clause without addressing the activity-versus-inactivity and economic-versus-noneconomic distinctions.
Candidates remember that the Commerce Clause is broad and stop there, without the limiting principles that modern doctrine imposes. They also overlook the Necessary and Proper Clause's role as a means to an enumerated end rather than an independent source of power.
What to do instead
For each federal statute, name the specific enumerated power invoked, then test the statute against that power's current limits. For the Commerce Clause, ask whether the regulated activity is economic, whether it substantially affects interstate commerce, and whether the statute regulates activity or compels it. Note when the Necessary and Proper Clause is doing the work.
Answering a question about incorporation or the scope of a right without noting which provision applies to the states and which applies only to the federal government, or assuming every Bill of Rights guarantee has been incorporated.
The incorporation doctrine is summarized as a single sentence in many outlines, so candidates assume uniformity. They then apply a non-incorporated guarantee against a state or apply a federal-only limit to state action.
What to do instead
Keep a short list of the guarantees that have not been incorporated and of provisions that apply only to the federal government. For any question involving state action, state expressly whether the right has been incorporated through the Fourteenth Amendment before analyzing the merits.
Writing a conclusion-first answer that names the outcome but never applies the governing standard to the specific facts, so the reasoning would support either result.
Candidates under time pressure reproduce rules from memory and then assert a conclusion, treating recitation as analysis. This also masks gaps in doctrine, since a rule statement can be correct while its application is wrong.
What to do instead
Use a fixed template for every answer: identify the issue, state the rule with its elements, apply each element to a named fact, then conclude. Reserve at least half the answer for application, and force yourself to cite the specific fact that satisfies or defeats each element.
