General law is the body of broadly applicable legal rules that governs everyone in a jurisdiction, rather than targeting particular people, groups, or situations. In the United States, it is built from four overlapping layers: constitutions, statutes passed by legislatures, court decisions that bind future cases, and regulations issued by government agencies. Together these layers shape nearly every interaction a person has with the state and with other private parties, from signing a lease to being charged with a crime.
The word “general” is doing real work in that definition. A general law applies by its terms to anyone who falls within its scope. It is not written for one company, one neighborhood, or one dispute. That universality is both a design feature and, as explained below, a constitutional requirement.
The Four Sources of General Law
Constitutional Law
The U.S. Constitution sits at the top of the hierarchy. It organizes the federal government into three branches, limits what government can do, and protects individual rights through provisions like the Bill of Rights and the Fourteenth Amendment. State constitutions do the same thing at the state level and often grant additional protections beyond what the federal Constitution requires.
Statutory Law
Statutes are the laws written and passed by Congress at the federal level and by legislatures at the state and local levels. Federal statutes are compiled in the United States Code, which organizes all general and permanent federal laws by subject across 53 titles.
Common Law
Common law develops case by case, through judges. When a court resolves a dispute and explains the reasoning, that decision becomes a reference point for future cases raising the same issue. The principle is called stare decisis: courts follow their own prior rulings and the rulings of higher courts in the same jurisdiction unless there is a strong reason to depart. Large areas of contract, tort, and property law are shaped primarily by common law rather than by statutes.
Administrative Regulations
Federal agencies — the Environmental Protection Agency, the Securities and Exchange Commission, and many others — issue detailed rules that carry the force of law within the boundaries Congress sets for them. These regulations are collected in the Code of Federal Regulations, which spans 50 subject-area titles. State agencies operate similarly under state law. Statutes tend to set broad goals; regulations fill in the operational detail that makes those goals enforceable.
What Makes a Law “General”
The defining feature of general law is uniform application. A statute making theft illegal does not single out particular individuals; it applies to everyone in the jurisdiction. This is partly a practical design choice and partly a constitutional command.
The Fourteenth Amendment’s Equal Protection Clause prohibits any state from denying “any person within its jurisdiction the equal protection of the laws.” That does not mean every law has to treat every person identically. Legislatures routinely draw distinctions, such as setting a minimum age for driving or imposing higher tax rates on higher incomes. But those classifications have to rest on some reasonable basis rather than arbitrary or invidious discrimination.
Due process is the companion guarantee. The Fifth Amendment binds the federal government and the Fourteenth Amendment binds the states, both prohibiting the government from depriving anyone of “life, liberty, or property, without due process of law.” In practice this means fair procedures — notice and an opportunity to be heard — before the government takes something away from you. Equal protection and due process together are the constitutional guardrails that keep general laws from becoming instruments of arbitrary power.
General Law vs. Special, Local, and Private Law
Not every law is general. Three contrasts help clarify what the term actually covers.
- Special law. A special law addresses a specific situation, location, or group rather than applying universally. When a special law and a general law conflict on the same subject, the special law usually controls, on the theory that a legislature writing a targeted rule for a specific problem wants that rule to govern over a broader one.
- Local law. Ordinances passed by cities, counties, and other municipalities govern matters like zoning, noise, and building codes within defined territorial boundaries. Local laws supplement state general law but cannot contradict it.
- Private law. This describes the area of law governing relationships between private parties — contracts, property disputes, family matters — in contrast with public law, which concerns the relationship between individuals and the government.
One boundary worth flagging: in municipal governance, “general law” has a narrower, specialized meaning. A general law city is one that derives all of its authority from statewide statutes rather than from its own locally adopted charter. If the state legislature has not granted a particular power to cities by statute, a general law city cannot exercise it. A home rule city, by contrast, adopts its own charter and can act unless state or federal law specifically prohibits it. If you arrived at this topic because of a question about what your city government can or cannot do, that municipal definition is the one you want, and it is distinct from the broader concept the rest of this article addresses.
How General Law Shapes Everyday Life
General legal principles are woven into routine activities most people do not think of as legal at all.
Contract Law
Buying groceries, signing up for a phone plan, accepting a job offer, renting an apartment: each of these is a contract, even when nothing is written down. Contract law sets the ground rules for what makes an agreement enforceable, what happens when one side fails to follow through, and what remedies are available. For sales of physical goods like electronics, furniture, and vehicles, most states follow the Uniform Commercial Code, a standardized set of rules drafted by the Uniform Law Commission and adopted in some form by all 50 states, so that a seller in one state and a buyer in another can transact under the same basic rules.
Tort Law
Tort law lets people harmed by someone else’s wrongful conduct seek compensation through a civil lawsuit. The most common theory is negligence, where you have to show the other party owed you a duty of care, breached it, and caused your injury. Some claims do not require proving fault at all. Strict liability holds a person or company responsible regardless of intent or carelessness; the familiar example is defective products, where a manufacturer that sells a dangerously defective product can be liable even if it took every reasonable precaution.
Criminal Law
Criminal law defines conduct the government can punish, from minor infractions to serious felonies. Two foundational principles run through nearly all criminal offenses. The prosecution must prove a prohibited act, called the actus reus, and a culpable mental state, called the mens rea — meaning the person acted intentionally, knowingly, recklessly, or negligently, depending on the offense. A narrow category of strict liability offenses, like certain regulatory violations, dispenses with the mental state requirement.
Property Law
Property law governs how people acquire, use, and transfer ownership of real estate and personal belongings. Owners hold a bundle of rights: to possess the property, use it, exclude others, and transfer it by sale or gift. Those rights are not absolute. Zoning laws, environmental regulations, and deed restrictions all limit what an owner can do, and under the doctrine of eminent domain the government can take private property for public use. When it does, the Fifth Amendment requires “just compensation,” which courts measure by the property’s fair market value at the time of the taking rather than any personal or sentimental value the owner attaches to it.
Federal Law and State Law in the Same System
Because general law exists at both the federal and state level, the two sometimes point in different directions. The Supremacy Clause in Article VI of the Constitution declares that federal law is “the supreme Law of the Land” and that state judges are bound by it, regardless of anything in state constitutions or statutes to the contrary. When a valid federal law directly conflicts with a state law, the federal law wins. Courts call this preemption. Congress can expressly state that a federal law overrides state law, or preemption can be implied when federal regulation of a subject is so thorough that no room remains for state rules, or when a state law makes it impossible to comply with a federal requirement.
Even so, courts start with a presumption against preemption, especially in areas states have traditionally regulated — family law, land use, criminal justice. Federal law does not automatically displace every state law that touches the same topic. The practical result is a layered system in which federal and state general laws coexist, each governing within its own lane unless Congress has clearly signaled otherwise.
How to Read the Laws That Apply to You
You do not need a law degree to look up the text of the laws that govern you. A few free or low-cost tools make it straightforward.
- Federal statutes. The United States Code is available at no cost through govinfo.gov and uscode.house.gov, organized across 53 subject-matter titles.
- Federal regulations. The Code of Federal Regulations, also on govinfo.gov, compiles agency rules across 50 titles organized by subject.
- Federal court records. The PACER system at pacer.uscourts.gov provides electronic access to more than one billion documents filed in federal courts, at $0.10 per page capped at $3.00 per document, with fees waived if you accrue $30 or less in a quarter.
- State statutes. Every state legislature maintains a free website where you can search and read state laws, and many are also compiled in searchable form through databases like Justia.
The U.S. Code by itself does not include agency regulations, court decisions, treaties, or state and local laws. For a complete picture of the general law applying to a given situation, you may need to consult the Code of Federal Regulations for agency rules, a case law database or PACER for court decisions, and your state legislature’s website for state statutes.
