Constitutional Law

Constitutional Law is the area of law that governs the structure and powers of the federal government and the individual rights protected against governmental action under the U.S. Constitution. It covers how power is allocated among the branches and between the federal government and the states, and the limits the Constitution places on what government may do to people.

What Constitutional Law covers

Constitutional Law on the bar exam and in law school divides into two broad halves: governmental structure and individual rights. The structure half asks how power is distributed, covering separation of powers among the legislative, executive, and judicial branches, federalism and the scope of congressional power (especially the Commerce Clause), and the limits federalism places on the states. The rights half asks what the Constitution forbids government from doing, covering the First Amendment (speech, press, religion, and assembly), due process and equal protection under the Fifth and Fourteenth Amendments, the takings of private property, and the threshold state action requirement that makes the Constitution applicable at all. The subject matters because it is heavily tested on the MBE and frequently appears on MEE essays, and because nearly every issue turns on selecting and applying the correct level of judicial scrutiny — rational basis, intermediate scrutiny, or strict scrutiny — to a challenged government action.

Key topics

First Amendment
Government generally may not abridge speech, press, assembly, or the free exercise of religion, and content-based speech restrictions are presumptively invalid and reviewed under strict scrutiny while content-neutral time, place, and manner rules face intermediate scrutiny.
Due Process
The Fifth and Fourteenth Amendments bar government from depriving a person of life, liberty, or property without fair procedures (procedural due process) and protect certain fundamental rights from substantive intrusion, with infringements on fundamental rights reviewed under strict scrutiny.
Equal Protection
Government classifications must satisfy the appropriate level of scrutiny — strict scrutiny for race, national origin, and fundamental rights, intermediate scrutiny for sex and legitimacy, and rational basis review for all other classifications.
Commerce Clause
Congress may regulate the channels and instrumentalities of interstate commerce, persons or things in interstate commerce, and activities that substantially affect interstate commerce, while the dormant Commerce Clause limits state laws that discriminate against or unduly burden interstate commerce.
Separation of Powers
The Constitution divides authority among the legislative, executive, and judicial branches, so that each branch's exercise of power is checked by the others and one branch may not unconstitutionally encroach on the core functions of another.
State Action Doctrine
Constitutional individual-rights protections restrain only governmental conduct, so a plaintiff must show state action — typically a public actor, a private party performing a traditional and exclusive public function, or significant government entanglement with private conduct.
Takings & Eminent Domain
Under the Fifth Amendment, government may take private property only for a public use and must pay just compensation, and regulations that go too far in restricting property use can constitute a compensable regulatory taking.

As you practice, LawCoach tracks which Constitutional Law topics are weakest and shapes a study plan so your time goes where it moves your score most. It is a study tool, not legal advice, and AI feedback can contain inaccuracies.

Frequently asked questions

What is the difference between procedural and substantive due process?
Procedural due process governs how government acts, requiring fair procedures — typically notice and a meaningful opportunity to be heard — before depriving a person of life, liberty, or property. Substantive due process governs what government may do, protecting certain fundamental rights from undue infringement regardless of the procedures used. Infringements on fundamental rights are reviewed under strict scrutiny, while non-fundamental rights receive rational basis review.
What levels of scrutiny does Constitutional Law use?
Constitutional Law uses three tiers of judicial scrutiny to test government action. Strict scrutiny, the hardest to satisfy, requires the law to be necessary to achieve a compelling government interest and applies to race classifications and fundamental rights. Intermediate scrutiny requires the law to be substantially related to an important interest and applies to sex and legitimacy classifications. Rational basis review, the most deferential, requires only a legitimate interest rationally related to the law and applies to everything else.
What is the state action requirement?
The state action requirement means constitutional individual-rights guarantees restrain only governmental conduct, not purely private behavior. A plaintiff must show a government actor, a private party performing a function traditionally and exclusively reserved to the state (the public function exception), or significant government entanglement with the private conduct. Without state action, claims based on rights like due process, equal protection, or free speech cannot proceed against a private party.
How does LawCoach grade Constitutional Law essays?
LawCoach grades practice essays with an AI reviewer panel that evaluates your answer across distinct skills.
