All legal systems deal with the same basic issues, but jurisdictions categorise and identify their legal topics in different ways. A common distinction is that between "
public law" (a term related closely to the
state, and including constitutional, administrative and criminal law), and "
private law" (which covers contract,
tort and property). In
civil law systems, contract and tort fall under a general
law of obligations, while trust law is dealt with under statutory regimes or
international conventions. International, constitutional and administrative law, criminal law, contract, tort, property law, and
trusts are regarded as the "traditional core subjects", although there are many further disciplines.
International law Constitutional and administrative law Constitutional and administrative law govern the affairs of the state. Constitutional law concerns both the relationships between the executive, legislature, and judiciary and the human rights or
civil liberties of individuals against the state. Most jurisdictions, like the
United States and
France, have a single codified constitution with a
bill of rights. A few, like the
United Kingdom, have no such document. A "constitution" is simply those laws which constitute the
body politic, from
statute,
case law, and
convention. The fundamental constitutional principle, inspired by
John Locke, holds that
the individual can do anything except that which is forbidden by law; the state may do nothing except that which is authorised by law. Administrative law is the chief method for people to hold state bodies to account. People (wheresoever allowed) may potentially have the prerogative to legally challenge (or sue) an agency, local council, public service, or government ministry for
judicial review of the offending
edict (law, ordinance, policy order). Such a challenge tests the government entity's ability to exercise actionable authority under the law and whether it observed the required procedure. The first specialist administrative court was the ''
Conseil d'État'' set up in 1799, as
Napoleon assumed power in France. A sub-discipline of constitutional law is
election law. It, along with
Elections commissions, councils, or committees, deals with policies and procedures that facilitate elections. These rules settle disputes or enable the translation of the will of the people into functioning
democracies. Election law addresses issues who is entitled to
vote,
voter registration,
ballot access,
campaign finance and
party funding,
redistricting,
apportionment,
electronic voting and
voting machines,
accessibility of elections,
election systems and formulas,
vote counting, election disputes,
referendums, and issues such as
electoral fraud and
electoral silence.
Criminal law Criminal law, also known as penal law, pertains to crimes and punishment. It thus regulates the definition of and penalties for offences found to have a sufficiently deleterious social impact, but, in itself, makes no moral judgment on an offender nor imposes restrictions on society that physically prevent people from committing a crime in the first place. Investigating, apprehending, charging, and trying suspected offenders is regulated by the law of
criminal procedure. The
paradigm case of a crime lies in the proof,
beyond reasonable doubt, that a person is guilty of two things. First, the accused must commit an act which is deemed by society to be criminal, or
actus reus (guilty act). Second, the accused must have the requisite
malicious intent to do a criminal act, or
mens rea (guilty mind). However, for so called "
strict liability" crimes, an
actus reus is enough. Criminal systems of the civil law tradition distinguish between intention in the broad sense (
dolus directus and
dolus eventualis), and negligence. Negligence does not carry criminal responsibility unless a particular crime provides for its punishment. (standing in glass booth at left) being sentenced to death at the conclusion of
his 1961 trial, an example of a criminal law proceeding Examples of crimes include murder, assault, fraud, and theft. In exceptional circumstances defences, can apply to specific acts, such as killing in
self defence or pleading
insanity. Another example is in the 19th-century English case of
R v Dudley and Stephens, which tested whether a defence of "
necessity" could justify murder and cannibalism to survive a shipwreck. Criminal law offences are viewed as offences against not just individual victims but also the community. The state, usually with the help of police, takes the lead in prosecution, which is why in common law countries cases are cited as "
The People v ..." or "
R (for
Rex or
Regina) v ...". Also, lay
juries are often used to determine defendants' guilt on points of fact; juries cannot change legal rules. Some developed countries still condone capital punishment for certain crimes. Still, the usual punishments for a crime are
imprisonment,
fines, state supervision (such as probation), or
community service. Modern criminal law has been affected considerably by the social sciences, especially with respect to
sentencing, legal research, legislation, and
rehabilitation. On the international field, 111 countries are
members of the
International Criminal Court, which was established to try people for
crimes against humanity.
Contract law was held to be a
unilateral contract. Contract law concerns enforceable promises, and can be summed up in the Latin phrase
pacta sunt servanda (agreements must be kept). In common law jurisdictions, three key elements to the creation of a contract are necessary:
offer and acceptance,
consideration, and the
intention to create legal relations. Consideration indicates the fact that all parties to a contract have exchanged something of value. Some common law systems, including Australia, are moving away from the requirement of consideration. The idea of
estoppel or
culpa in contrahendo can be used to create obligations during pre-contractual negotiations. Civil law jurisdictions treat contracts differently in several respects, with a more interventionist role for the state in both their formation and enforcement. Compared to common law jurisdictions, civil law systems incorporate more mandatory terms into contracts, allow greater latitude for courts to interpret and revise contract terms and impose a stronger
duty of good faith, but are also more likely to enforce
penalty clauses and
specific performance of contracts. They also do not require consideration for a contract to be binding. In France, an ordinary contract is said to form based on a "meeting of the minds" or a "concurrence of wills".
Germany has a distinct approach to contracts that is closely tied to property law. Their '
abstraction principle' (
Abstraktionsprinzip) means that the personal obligation of contract forms separately from the title of property being conferred. When contracts are invalidated for some reason (e.g., a car buyer is so drunk that he lacks legal capacity to contract) the contractual obligation to pay can be invalidated separately from the proprietary title of the car.
Unjust enrichment law, rather than contract law, is then used to restore title to the rightful owner.
Torts and delicts Certain
civil wrongs are grouped together as
torts under common law systems and
delicts under civil law systems. To have acted tortiously, one must have breached a duty to another person, or infringed some pre-existing legal right. A simple example might be unintentionally hitting someone with a ball. Under the law of
negligence, the most common form of tort, the injured party could potentially claim compensation for their injuries from the party responsible. The principles of negligence are illustrated by
Donoghue v Stevenson. A friend of Donoghue ordered an opaque bottle of
ginger beer (intended for the consumption of Donoghue) in a café in
Paisley. Having consumed half of it, Donoghue poured the remainder into a tumbler. The decomposing remains of a snail floated out. She claimed to have suffered from shock, fallen ill with gastroenteritis, and sued the manufacturer for carelessly allowing the drink to be contaminated. The
House of Lords decided that the manufacturer was liable for Mrs Donoghue's illness.
Lord Atkin took a distinctly moral approach and said: The liability for negligence [...] is no doubt based upon a general public sentiment of moral wrongdoing for which the offender must pay. [...] The rule that you are to love your neighbour becomes in law, you must not injure your neighbour; and the
lawyer's question, Who is my neighbour? receives a restricted reply. You must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour. This became the basis for the four principles of negligence, namely that: • Stevenson owed Donoghue a
duty of care to provide safe drinks; • he
breached his duty of care; • the harm would not have occurred
but for his breach; and • his act was the
proximate cause of her harm. Another example of tort might be a neighbour making excessively loud noises with machinery on his property. Under a
nuisance claim, the noise could be stopped. Torts can also involve intentional acts such as
assault,
battery or
trespass. A better-known tort is
defamation, which occurs, for example, when a newspaper makes unsupportable allegations that damage a politician's reputation. More infamous are economic torts, which form the basis of
labour law in some countries by making trade unions liable for strikes, when statute does not provide immunity.
Property law '' by
Edward Matthew Ward. The
South Sea Bubble in 1720, one of the world's first-ever speculative bubbles and crashes, led to the strict regulation of share trading.
Property law governs ownership and possession.
Real property, sometimes called 'real estate', refers to ownership of land and things attached to it.
Personal property, refers to everything else; movable objects, such as computers, cars, jewelry or intangible rights, such as
stocks and shares. A right
in rem is a right to a specific piece of property, in contrast to a right
in personam, which allows compensation for a loss but not for a particular thing. Land law forms the basis for most kinds of property law and is the most complex. It concerns
mortgages,
rental agreements,
licences,
covenants,
easements and the statutory systems for land registration. Regulations on the use of personal property fall under intellectual property,
company law,
trusts, and
commercial law. A representative example of property law is the 1722 case of
Armory v Delamirie, which applied
English law. A child was deprived of possession of the gemstones that had been set in a piece of jewellery, by the businessperson entrusted to appraise the piece. The court held that, under the common law view of property, the person who can show the
best claim to a piece of property, against any contesting party, is the owner. By contrast, the classic civil law approach to property, propounded by
Friedrich Carl von Savigny, is that it is a right good against the world. Obligations, such as those arising from contracts and torts, are conceptualised as rights owed by individuals. The idea of property raises many further philosophical and political issues. Locke argued that our "lives, liberties and estates" are our property because we own our bodies and
mix our labour with our surroundings.
Trusts In historical
English law, the common law did not permit dividing the
ownership from the
control of one piece of property—but the law of equity did recognize this through an arrangement known as a trust. Trustees control property, whereas the beneficial, or equitable, ownership of trust property is held by people known as beneficiaries. Trustees owe their beneficiaries a duty to take good care of the property entrusted to them. Another example of a trustee's duty might be to invest property wisely or sell it. This is especially the case for pension funds, the most important form of trust, where investors are trustees for people's savings until retirement. But trusts can also be set up for
charitable purposes. Some international norms for the structure and regulation of trusts are set out in the
Hague Trust Convention of 1985. == Intersection with other fields ==
