.
The relationships public law governs are asymmetric and unequalized. Government bodies (central or local) can make decisions about the rights of persons. However, as a consequence of the
rule-of-law doctrine, authorities may only act within the law (''secundum et intra legem''). The government must obey the law. For example, a citizen unhappy with a decision of an administrative authority can ask a court for
judicial review.
The distinction between public law and private law dates back to
Roman law, where the
Roman jurist
Ulpian ( 170 – 228) first noted it.
It was later adopted to understand the legal systems both of countries that adhere to the
civil-law tradition, and of those that adhere to
common-law tradition.
The borderline between public law and private law is not always clear. Law as a whole cannot neatly be divided into "law for the State" and "law for everyone else". As such, the distinction between public and private law is largely functional rather than factual, classifying laws according to which domain the activities, participants, and principal concerns involved best fit into.
This has given rise to attempts to establish a
theoretical understanding for the basis of public law.
History of public law
The distinction between public and private law was first made by
Roman jurist Ulpian, who argues in the ''Institutes'' (in a passage preserved by
Justinian in the
''Digest'' ) that "
blic law is that which respects the establishment of the Roman commonwealth, private that which respects individuals' interests, some matters being of public and others of private interest." Furthermore, he defines public law as the law concerning religious affairs, the priesthood, and
offices of the State.
Roman Law conceived of the law as a series of relationships between persons and persons, persons and things, and persons and the State. Public law consisted of the latter of these three relationships. However, Roman lawyers devoted little attention to this area, and instead focussed largely on areas of private law. It was, however, of great importance in
Teutonic society, as noted by German legal historian
Otto von Gierke, who defined the Teutons as the fathers of public law.
Drawing a line between public and private law largely fell out of favor in the ensuing millennium, though, as
Ernst Kantorowicz notes,
Medieval jurists saw a concern with the Roman conception of the ''
res publica'' inherent in the
legal fiction of the
king's two bodies.
However,
legal philosophers during this period were largely theologians who operated within the realm of
Canon Law

natural law

, and
human law.
The "public/private" divide in law would not return until the 17th and 18th centuries. Through the emergence of the
nation-state and new theories of
sovereignty, notions of a distinctly
public realm began to crystalize. However, the claims made by monarchs, and later parliaments, to an unrestrained power to make law spurred attempts to establish a distinctly
private sphere that would be free from encroaching State power in return.
Public law in civil law and common law jurisdictions
Traditionally, the division between public and private law has been made in the context of the legal systems found in Continental Europe, whose laws all fall within the tradition of
civil law. However, the public/private divide does not apply strictly to civil law systems. Given public law's emphasis on aspects of the State that are true of all systems of government and law,
common law
Common law (also known as judicial precedent, judge-made law, or case law) is the body of law primarily developed through judicial decisions rather than statutes. Although common law may incorporate certain statutes, it is largely based on prece ...
legal systems acknowledge, even if they do so unconsciously, that actions which must be prohibited by the State need not necessarily be prohibited for private parties as well. As such, legal scholars commenting on common law systems, such as England
and Canada, have made this distinction as well.
For many years, public law occupied a marginal position in continental European law. By and large, private law was considered ''general law''. Public law, on the other hand, was considered to consist of exceptions to this general law. It was not until the second half of the twentieth century that public law began to play a prominent role in European society through the
constitutionalization of private law, as well as the development of
administrative law
Administrative law is a division of law governing the activities of government agency, executive branch agencies of government. Administrative law includes executive branch rulemaking (executive branch rules are generally referred to as "regul ...
and various functional fields of law, including
labor law,
medical law, and
consumer law. Though this began to blur the distinction between public and private law, it did not erode the former. Instead, it elevated public law from its once marginal state, with an acknowledgment that there are few, if any, areas of the law that are free from potential State intervention. In Italy, for example, the development of public law was considered a project of
state-building, following the ideas of
Vittorio Emanuele Orlando. Indeed, many early Italian public lawyers were also politicians, including Orlando himself.
Now, in countries such as France,
public law now refers to the areas of

Areas of public law
Constitutional law
In modern states,
constitutional law

lays out the foundations of the state. Above all, it postulates the supremacy of law in the functioning of the state – the
rule of law.
Secondly, it sets out the form of government – how its different branches work, how they are elected or appointed, and the division of powers and responsibilities between them. Traditionally, the basic elements of government are
the executive,
the legislature and
the judiciary.
And thirdly, in describing what are the basic human rights, which must be protected for every person, and what further
civil and political rights citizens have, it sets the fundamental borders to what ''any'' government must and must not do.
In most jurisdictions, constitutional law is enshrined in a written document, the Constitution, sometimes together with amendments or other constitutional laws. In some countries, however, such a supreme entrenched written document does not exist for historical and political reasons – the
Constitution of the United Kingdom is an unwritten one.
Administrative law
Administrative law
Administrative law is a division of law governing the activities of government agency, executive branch agencies of government. Administrative law includes executive branch rulemaking (executive branch rules are generally referred to as "regul ...
refers to the body of law that regulates bureaucratic managerial procedures and defines the powers of administrative agencies. These laws are enforced by the
executive branch of a government rather than the
judicial or
legislative branches (if they are different in that particular jurisdiction). This body of law regulates
international trade, manufacturing, pollution, taxation, and the like. This is sometimes seen as a subcategory of
civil law and sometimes seen as public law as it deals with regulation and public institutions
Criminal law
Criminal law is the body of
law that relates to
crime
In ordinary language, a crime is an unlawful act punishable by a State (polity), state or other authority. The term ''crime'' does not, in modern criminal law, have any simple and universally accepted definition,Farmer, Lindsay: "Crime, definiti ...

health,
safety, and
welfare of people inclusive of one's self. Most criminal law is established by
statute, which is to say that the laws are enacted by a
legislature. Criminal law includes the
punishment and
rehabilitation of people who violate such laws.
Tax law
Tax law first became an area of public law during the 17th century, as a consequence of new theories of sovereignty that began to emerge. Until this point, taxes were considered gifts under the law, given to the State by a private donor – the taxpayer. It is now considered an area of public law, as it concerns a relationship between persons and the State.
Theoretical distinction between private and public law
The analytical and historical distinction between public and private law has emerged predominantly in the legal systems of
continental Europe
Continental Europe or mainland Europe is the contiguous mainland of Europe, excluding its surrounding islands. It can also be referred to ambiguously as the European continent, – which can conversely mean the whole of Europe – and, by som ...
. As a result, German-language legal literature has produced extensive discussion on the precise nature of the distinction between public law and private law. Several theories have evolved, which are neither exhaustive nor mutually exclusive or separate.
The interest theory of public law emerges from the work of
Roman jurist
Ulpian, who stated "''Publicum ius est, quod ad statum rei Romanae spectat, privatum quod ad singulorum utilitatem.'' (Public law is that which concerns the Roman state, and private law is concerned with the interests of citizens.)
Charles-Louis Montesquieu elaborates upon this theory in
''The Spirit of the Laws'', published during the 18th century, wherein Montesquieu establishes a distinction between international (right of nations), public (political right), and private (civil right) law according to various actors interests and rights. There, he writes: "Considered as inhabitants of a planet so large that different peoples are necessary, they have laws bearing on the relation that these peoples have with one another, and this is the . Considered as living in a society that must be maintained, they have laws concerning the relation between those who govern and those who are governed, and this is the . Further, they have laws concerning the relation that all citizens have with one another, and this is the ."
Criticisms of interest theory include the difficulty in establishing a clear distinction between private and public interest if such a distinction does exist, and categorizing laws accordingly.
The subjection theory focuses on explaining the distinction by emphasizing the subordination of private persons to the state. Public law is supposed to govern this relationship, whereas private law is considered to govern relationships where the parties involved meet on a level playing field. However, some areas commonly considered private law also imply subordination, such as
employment law
Labour laws (also spelled as labor laws), labour code or employment laws are those that mediate the relationship between workers, employing entities, trade unions, and the government. Collective labour law relates to the tripartite relationship be ...
. Moreover, legal proceedings wherein the State is a party may undermine the totality of the State's authority, and the degree to which private persons are subordinate to the State if a Court finds in favor of a non-state party (see
Carpenter v. United States, for example).
The subject theory is concerned with the position of the subject of law in the legal relationship in question. If it finds itself in a particular situation as a public person (due to membership in some public body, such as a state or a municipality), public law applies, otherwise it is private law.
A combination of the subjection theory and the subject theory arguably provides a workable distinction. Under this approach, a field of law is considered public law where one actor is a public authority endowed with the power to act unilaterally (''imperium'') and this actor uses that ''imperium'' in the particular relationship. In other words, it all depends on whether the public authority is acting as a public or a private entity, say when ordering office supplies. This latest theory considers public law a special instance.
There are areas of law that do not seem to fit into either public or private law, such as
employment law
Labour laws (also spelled as labor laws), labour code or employment laws are those that mediate the relationship between workers, employing entities, trade unions, and the government. Collective labour law relates to the tripartite relationship be ...
– parts of it look like private law (the employment contract) while other parts look like public law (the activities of an employment inspectorate when investigating workplace safety).
The distinction between public and private law has a bearing on the delineation between the competencies of different courts and administrative bodies. Under the
Austrian constitution, for example, private law is among the exclusive competencies of federal legislation, whereas public law is partly a matter of
state legislation.
