# English law

English law is the common law legal system of England and Wales, comprising mainly criminal law and civil law, each branch having its own courts and procedures. The judiciary is independent, and legal principles like fairness, equality before the law, and the right to a fair trial are foundational to the system.

## Principal elements

Although the common law has, historically, been the foundation and prime source of English law, the most authoritative law is statutory legislation, which comprises Acts of Parliament, regulations and by-laws. In the absence of any statutory law, the common law with its principle of stare decisis forms the residual source of law, based on judicial decisions, custom, and usage.
Common law is made by sitting judges who apply both statutory law and established principles which are derived from the reasoning from earlier decisions. Equity is the other historic source of judge-made law. Common law can be amended or repealed by Parliament.
Not being a civil law system, it has no comprehensive codification. However, most of its criminal law has been codified from its common law origins, in the interests both of certainty and of ease of prosecution. For the time being, murder remains a common law crime rather than a statutory offence.
Although Scotland and Northern Ireland form part of the United Kingdom and share Westminster as a primary legislature, they have separate legal systems outside English law.
International treaties such as the European Union's Treaty of Rome or the Hague-Visby Rules have effect in English law only when adopted and ratified by Act of Parliament. Adopted treaties may be subsequently denounced by executive action, unless the denouncement or withdraw would affect rights enacted by Parliament. In this case, executive action cannot be used owing to the doctrine of parliamentary sovereignty. This principle was established in the case of R (Miller) v Secretary of State for Exiting the European Union in 2017.

## Legal terminology
### Criminal law and civil law

Criminal law is the law of crime and punishment whereby the Crown prosecutes the accused. Civil law is concerned with tort, contract, families, companies and so on. Civil law courts operate to provide a party who has an enforceable claim against another party with a remedy such as damages or a declaration.

### Common law and civil law

In this context, civil law is the system of codified law that is prevalent in the rest of Europe. Civil law is founded on the ideas of Roman law.
By contrast, English law is the archetypal common law jurisdiction, built upon case law.

### Common law and equity

In this context, "common law" means the judge-made law of the King's Bench; whereas equity is the judge-made law of the (now-defunct) Court of Chancery. Equity is concerned mainly with trusts and equitable remedies. Equity generally operates in accordance with the principles known as the "maxims of equity".
The reforming Judicature Acts of the 1880s amalgamated the courts into one Supreme Court of Judicature which was directed to administer both law and equity. The neo-Gothic Royal Courts of Justice in The Strand, London, were built shortly afterwards to celebrate these reforms.

### Public law and private law

Public law is the law governing relationships between individuals and the state. Private law encompasses relationships between private individuals and other private entities (but may also cover "private" relationships between the government and private entities).

### Legal remedies

A remedy is "the means given by law for the recovery of a right, or of compensation for its infringement". Most remedies are available only from the court, but some are "self-help" remedies; for instance, a party who lawfully wishes to cancel a contract may do so without leave; and a person may take his own steps to "abate a private nuisance".
Formerly, most civil actions claiming damages in the High Court were commenced by obtaining a writ issued in the Queen's name. After 1979, writs have merely required the parties to appear, and writs are no longer issued in the name of the Crown. After the Woolf Reforms of 1999, almost all civil actions other than those connected with insolvency are commenced by the completion of a Claim Form as opposed to a writ, originating application, or a summons.

## Sources of English law

In England there is a hierarchy of sources, as follows:
* Legislation (primary and secondary)
* The case law rules of common law and equity, derived from precedent decisions
* Parliamentary conventions
* General customs
* Books of authority
The rule of European Union law in England, previously of prime importance, has been ended as a result of Brexit.

## Statute law

Primary legislation in the UK may take the following forms:
* Acts of Parliament
* Acts of the Scottish Parliament
* Acts of the Senedd, or previously Acts of the National Assembly for Wales and measures of the National Assembly for Wales
* Statutory rules of the Northern Ireland Assembly
Orders in Council are a sui generis category of legislation.
Secondary (or "delegated") legislation in England includes:
* Statutory instruments and ministerial orders
* By-laws of metropolitan boroughs, county councils, and town councils
Statutes are cited in this fashion: "Short Title Year", e.g. Theft Act 1968. This became the usual way to refer to Acts from 1840 onwards; previously Acts were cited by their long title with the regnal year of the parliamentary session when they received royal assent, and the chapter number. For example, the Pleading in English Act 1362 (which required pleadings to be in English and not Law French) was referred to as 36 Edw. 3. c. 15, meaning "36th year of the reign of Edward III, chapter 15". (By contrast, American convention inserts "of", as in "Civil Rights Act of 1964").

## Common law

Common law is a term with historical origins in the legal system of England. It denotes, in the first place, the Anglo-Norman legal system that superseded and replaced Anglo-Saxon law in England following the Battle of Hastings in 1066. Throughout the Late Medieval Period, English law was codified through judge-made laws and precedents that were created in the proceedings of Royal justices in the Circuit courts dictated by the Eyres throughout the country (these themselves evolving from the early medieval Itinerant courts). This body of legal scholarship was first published at the end of the 19th century, The History of English Law before the Time of Edward I, in which Pollock and Maitland expanded the work of Coke (17th century) and Blackstone (18th century). Specifically, the law developed in England's Court of Common Pleas and other common law courts, which became also the law of the colonies settled initially under the Crown of England or, later, of the United Kingdom, in United States, Canada, Australia, New Zealand, South Africa, Singapore, Indian Subcontient, Israel and elsewhere.
This law further developed after those courts in England were reorganised by the Supreme Court of Judicature Acts passed in the 1870s. It developed independently, in the legal systems of the United States and other jurisdictions, after their independence from the United Kingdom, before and after the 1870s. The term is used, in the second place, to denote the law developed by those courts, in the same periods, pre-colonial, colonial and post-colonial, as distinct from within the jurisdiction, or former jurisdiction, of other courts in England: the Court of Chancery, the ecclesiastical courts, and the Admiralty court.
In the Oxford English Dictionary (1933) "common law" is described as "The unwritten law of England, administered by the King's courts, which purports to be derived from ancient usage, and is embodied in the older commentaries and the reports of abridged cases", as opposed, in that sense, to statute law, and as distinguished from the equity administered by the Chancery and similar courts, and from other systems such as ecclesiastical law, and admiralty law. For usage in the United States the description is "the body of legal doctrine which is the foundation of the law administered in all states settled from England, and those formed by later settlement or division from them".

### Early development

In 1276, the concept of "time immemorial" often applied in common law, was defined as being any time before 6 July 1189 (i.e. before Richard I's accession to the English throne). Since 1189, English law has been a common law, not a civil law system. In other words, no comprehensive codification of the law has taken place and judicial precedents are binding as opposed to persuasive. This may be a legacy of the Norman Conquest of England in 1066, when a number of legal concepts and institutions from Norman law were introduced to England.
In the early centuries of English common law, the justices and judges were responsible for adapting the system of writs to meet everyday needs, applying a mixture of precedent and common sense to build up a body of internally consistent law. An example is the Law Merchant derived from the "Pie-Powder" Courts, named from a corruption of the French pieds-poudrés ("dusty feet") implying ad hoc marketplace courts.
Following Montesquieu's theory of the "separation of powers", only Parliament has the power to legislate. If a statute is ambiguous, then the courts have exclusive power to decide its true meaning, using the principles of statutory interpretation. Since the courts have no authority to legislate, the "legal fiction" is that they "declare" (rather than "create") the common law. The House of Lords took this "declaratory power" a stage further in DPP v Shaw, where, in creating the new crime of "conspiracy to corrupt public morals", Viscount Simonds claimed the court had a "residual power to protect the moral welfare of the state". As Parliament became ever more established and influential, Parliamentary legislation gradually overtook judicial law-making, such that today's judges are able to innovate only in certain, very narrowly defined areas.

### Overseas influences
#### Reciprocity

England exported its common law and statute law to most parts of the British Empire. Many aspects of that system have survived after Independence from British rule, and the influences are often reciprocal. "English law" prior to the American Revolutionary Wars (American War of Independence) is still an influence on American law, and provides the basis for many American legal traditions and principles.
After independence, English common law still exerted influence over American common law – for example, Byrne v Boadle (1863), which first applied the res ipsa loquitur doctrine. Jurisdictions that have kept to the common law may incorporate modern legal developments from England, and English decisions are usually persuasive in such jurisdictions.
In the United States, each state has its own supreme court with final appellate jurisdiction, resulting in the development of state common law. The US Supreme Court has the final say over federal matters. By contrast, in Australia, one national common law exists.

#### Courts of final appeal

After Britain's colonial period, jurisdictions that had inherited and adopted England's common law developed their courts of final appeal in differing ways: jurisdictions still under the British crown are subject to the Judicial Committee of the Privy Council in London. For a long period, the British Dominions used London's Privy Council as their final appeal court, although one by one they eventually established their local supreme court. New Zealand was the last Dominion to abandon the Privy Council, setting up its own Supreme Court in 2004.
Even after independence, many former British colonies in the Commonwealth continued to use the Privy Council, as it offered a readily available high-grade service. In particular, several Caribbean Island nations found the Privy Council advantageous.

#### International law and commerce

Britain is a dualist in its relationship with international law, so international treaties must be formally ratified by Parliament and incorporated into statute before such supranational laws become binding in the UK.
Britain has long been a major trading nation, exerting a strong influence on the law of shipping and maritime trade. The English law of salvage, collisions, ship arrest, and carriage of goods by sea are subject to international conventions which Britain played a leading role in drafting. Many of these conventions incorporate principles derived from English common law and documentary procedures.

## British jurisdictions

The United Kingdom of Great Britain and Northern Ireland comprises three legal jurisdictions: England and Wales, Scotland, and Northern Ireland. Although Scotland and Northern Ireland form part of the United Kingdom and share the Parliament at Westminster as the primary legislature, they have separate legal systems. Scotland became part of the UK over 300 years ago, but Scots law has remained remarkably distinct from English law.
The UK's highest civil appeal court is the Supreme Court of the United Kingdom, whose decisions, and those of its predecessor the House of Lords, are binding on all three UK jurisdictions. Unless obviously limited to a principle of distinct English and Welsh, Scottish or Northern Irish law, as in Donoghue v Stevenson, a Scots case that forms the basis of the UK's law of negligence.

### Application of English law to Wales

Unlike Scotland and Northern Ireland, Wales is not a separate jurisdiction within the United Kingdom. The customary laws of Wales within the Kingdom of England were abolished by King Henry VIII's Laws in Wales Acts, which brought Wales into legal conformity with England. While Wales now has a devolved parliament (the Senedd), any legislation it passes must adhere to circumscribed subjects under the Government of Wales Act 2006, to other legislation of the British Parliament, or to any Order in Council given under the authority of the 2006 Act.
Any reference to England in legislation between 1746 and 1967 is deemed to include Wales. As to later legislation, any application to Wales must be expressed under the Welsh Language Act 1967 and the jurisdiction is, since, correctly and widely referred to as England and Wales.
Devolution has granted some political autonomy to Wales via the Welsh Parliament, which gained its power to pass primary legislation under the Government of Wales Act 2006, in force since the 2007 Welsh general election. The legal system administered through civil and criminal courts is unified throughout England and Wales.
This is different from Northern Ireland, for example, which did not cease to be a distinct jurisdiction when its legislature was suspended (see Northern Ireland (Temporary Provisions) Act 1972). A major difference is use of the Welsh language, as laws concerning it apply in Wales and not in the rest of the United Kingdom. The Welsh Language Act 1993 is an Act of the Parliament of the United Kingdom, which put the Welsh language on an equal footing with the English language in Wales with regard to the public sector. Welsh may also be spoken in Welsh courts.
There have been calls from both Welsh academics and politicians for a separate Welsh justice system.
