Definition
General law has two related but distinct meanings in legal usage:
1. A law of universal or broad application — one framed in general terms, restricted to no particular locality, and operating uniformly upon all members of a defined class of persons, places, or things. As distinguished from a special or local law, a general law does not single out specific individuals, named localities, or isolated objects for treatment. It applies wherever and whenever its conditions are met, without reference to a particular plan or object.
2. In constitutional and legislative contexts, general law refers to a statute that qualifies under state constitutional restrictions on special or local legislation. Many state constitutions prohibit the legislature from passing special or local acts where a general law can be made applicable. Whether a statute qualifies as a general law — rather than a prohibited special act — is often a threshold constitutional question.
These two meanings are closely related. The first is descriptive; the second is operative and carries constitutional weight.
Common Confusion
General law is frequently contrasted with — and confused with — three related categories:
- Special law: Operates upon a specifically named or enumerated subject rather than a defined class. A law applicable only to the City of Philadelphia, named by name, is special; a law applicable to all cities above 500,000 population is general.
- Local law: Confined by geographic boundaries to a particular district or municipality. A law may be both special and local, but they are distinct concepts.
- Private law: Operates upon a specific named individual or private entity rather than a class. General law, by contrast, operates on whoever falls within the class.
The critical distinction courts draw is whether the classification used in the statute is genuine — whether it includes all persons or places that naturally belong to the described class — or whether it is a gerrymandered category designed to include or exclude a predetermined target.
Core Elements
For a statute to qualify as a general law, courts have historically applied the following criteria:
- General terms: The statute is framed without naming specific individuals, places, or objects.
- Uniform operation: It applies equally to all members of the class to which it relates.
- Natural and open class: The class is defined by legitimate characteristics, not constructed to reach predetermined targets. No subject or place that naturally belongs to the class is omitted.
- No fixed locality restriction: The law is not confined to a single county, city, or district.
Some courts add that the class must be substantial — not a class of one dressed in general language.
Why It Matters in Research
The term general law appears throughout nineteenth- and twentieth-century legislative history and constitutional adjudication, but its meaning shifts depending on context. Researchers must track which meaning is operative in a given source.
State constitutional research is the primary terrain. Dozens of state constitutions adopted between 1850 and 1920 included provisions prohibiting special or local legislation where a general law would suffice. Litigation over whether a given statute satisfied the general law requirement generated an enormous body of state case law. This body of authority is often invisible to researchers relying on secondary sources, which tend to focus on federal constitutional law.
The corpus contains significant variation by state. New Jersey, Pennsylvania, and Ohio courts were particularly active in developing tests for general law status in the late nineteenth century. The Black's entries in the corpus reflect this case law tradition. Researchers working in any state with a constitutional special-legislation prohibition should locate that state's own doctrinal line before relying on general formulations.
The term also appears in admiralty and federal common law contexts, where general maritime law refers to the body of judicially developed admiralty principles operating independently of any specific statute — a usage distinct from the constitutional/legislative meaning described above. See the Encyclopedia Cross-Reference below.
In modern regulatory research, general law sometimes contrasts with enabling legislation or organic statutes to describe background statutory frameworks versus targeted program-specific enactments. This usage is informal and lacks the technical precision of the constitutional sense.
Historical sources will often use general law as the opposite of special act without defining their terms carefully. A researcher encountering this usage in a nineteenth-century source should assume the constitutional special-legislation context unless the surrounding discussion indicates otherwise.
Historical Dictionary Support
Black's Law Dictionary frames general law in explicitly comparative terms — a law embracing a class of subjects or places that does not omit any subject or place naturally belonging to that class. The New Jersey citation in Black's (40 N.J. Law, 1) reflects the robust state-court jurisprudence on special legislation that developed in the post-Civil War era. Black's emphasis on uniform operation and restriction to no locality tracks the dominant judicial test of the period.
Bouvier's Law Dictionary adds useful precision by grounding the definition in the class-legislation framework: laws applying uniformly to all members of any class of persons, places, or things requiring legislation peculiar to themselves. The Pennsylvania citation (77 Pa. 348) and the Binney reference point toward academic and judicial literature on restrictions on special and local legislation that was influential in the late nineteenth century. Bouvier's formulation emphasizes the connection between general law status and the purpose of the legislation — a more functional test than Black's more formal description.
Neither dictionary meaningfully engages with the admiralty usage of general law, nor do they address the twentieth-century administrative law context in which the term appears with different valence. Both sources reflect the constitutional special-legislation problem as their organizing concern.
Jurisdictional Note
The constitutional significance of general law status varies sharply by state. States with explicit constitutional prohibitions on special legislation — including Pennsylvania, New Jersey, Illinois, and many others — developed extensive case law on what qualifies. States without such provisions use the term descriptively without the same constitutional stakes. Federal law uses general law most prominently in the admiralty context, where it carries an entirely separate doctrinal meaning.
