Constitutional law is a body of law which defines the role, powers, and structure of different entities within a state, namely, the executive, the parliament or legislature, and the judiciary; as well as the basic rights of citizens and, in federal countries such as the United States and Canada, the relationship between the central government and state, provincial, or territorial governments.
Not all nation states have codified constitutions, though all such states have a jus commune , or law of the land, that may consist of a variety of imperative and consensual rules. These may include customary law, conventions, statutory law, judge-made law, or international rules and norms. Constitutional law deals with the fundamental principles by which the government exercises its authority. In some instances, these principles grant specific powers to the government, such as the power to tax and spend for the welfare of the population. Other times, constitutional principles act to place limits on what the government can do, such as prohibiting the arrest of an individual without sufficient cause.
In most nations, such as the United States, India, and Singapore, constitutional law is based on the text of a document ratified at the time the nation came into being. Other constitutions, notably that of the United Kingdom, [1] [2] rely heavily on uncodified rules, as several legislative statutes and constitutional conventions, their status within constitutional law varies, and the terms of conventions are in some cases strongly contested. [3]
Constitutional laws can be considered second order rule making or rules about making rules to exercise power. It governs the relationships between the judiciary, the legislature and the executive with the bodies under its authority. One of the key tasks of constitutions within this context is to indicate hierarchies and relationships of power. For example, in a unitary state, the constitution will vest ultimate authority in one central administration and legislature, and judiciary, though there is often a delegation of power or authority to local or municipal authorities. When a constitution establishes a federal state for instance as seen in India, it will identify multiple levels of government coexisting with exclusive or shared areas of jurisdiction over lawmaking, application and enforcement. Some federal states, most notably the United States, have separate and parallel federal and state judiciaries, with each having its own hierarchy of courts with a supreme court for each state. India, on the other hand, has one judiciary divided into district courts, high courts, and the Supreme Court of India.
Human rights or civil liberties form a crucial part of a country's constitution and uphold the rights of the individual against the state. Most jurisdictions, like the United States and France, have a codified constitution, with a bill of rights. A recent example is the Charter of Fundamental Rights of the European Union which was intended to be included in the Treaty establishing a Constitution for Europe, that failed to be ratified. Perhaps the most important example is the Universal Declaration of Human Rights under the UN Charter. These are intended to ensure basic political, social and economic standards that a nation state, or intergovernmental body is obliged to provide to its citizens but many do include its governments. Canada is another instance where a codified constitution, with the Canadian Charter of Rights and Freedoms, protects human rights for people under the nation's jurisdiction. [4]
Some countries like the United Kingdom have no entrenched document setting out fundamental rights; in those jurisdictions the constitution is composed of statute, case law and convention. A case named Entick v. Carrington [5] is a constitutional principle deriving from the common law. John Entick's house was searched and ransacked by Sherriff Carrington. Carrington argued that a warrant from a Government minister, the Earl of Halifax was valid authority, even though there was no statutory provision or court order for it. The court, led by Lord Camden stated that,
"The great end, for which men entered into society, was to secure their property. That right is preserved sacred and incommunicable in all instances, where it has not been taken away or abridged by some public law for the good of the whole. By the laws of England, every invasion of private property, be it ever so minute, is a trespass... If no excuse can be found or produced, the silence of the books is an authority against the defendant, and the plaintiff must have judgment." [6]
The common law and the civil law jurisdictions do not share the same constitutional law underpinnings. Common law nations, such as those in the Commonwealth as well as the United States, derive their legal systems from that of the United Kingdom, and as such place emphasis on judicial precedent, [7] [8] [9] whereby consequential court rulings (especially those by higher courts) are a source of law. Civil law jurisdictions, on the other hand, place less emphasis on judicial review and only the parliament or legislature has the power to effect law. As a result, the structure of the judiciary differs significantly between the two, with common law judiciaries being adversarial and civil law judiciaries being inquisitorial. Common law judicatures consequently separate the judiciary from the prosecution, [10] [11] [12] thereby establishing the courts as completely independent from both the legislature and law enforcement. Human rights law in these countries is as a result, largely built on legal precedent in the courts' interpretation of constitutional law, whereas that of civil law countries is almost exclusively composed of codified law, constitutional or otherwise.
Another main function of constitutions may be to describe the procedure by which parliaments may legislate. For instance, special majorities may be required to alter the constitution. In bicameral legislatures, there may be a process laid out for second or third readings of bills before a new law can enter into force. Alternatively, there may further be requirements for maximum terms that a government can keep power before holding an election.

Constitutional law is a major focus of legal studies and research. For example, most law students in the United States are required to take a class in Constitutional Law during their first year, and several law journals are devoted to the discussion of constitutional issues.
The doctrine of the rule of law dictates that government must be conducted according to law. This was first established by British legal theorist A. V. Dicey.
Dicey identified three essential elements of the British Constitution which were indicative of the rule of law:
Dicey's rule of law formula consists of three classic tenets. The first is that the regular law is supreme over arbitrary and discretionary powers. "[N]o man is punishable ... except for a distinct breach of the law established in the ordinary legal manner before the ordinary courts of the land." [14]
The second is that all men are to stand equal in the eyes of the law. "...no man is above the law...every man, whatever be his rank or condition, is subject to the ordinary law of the realm and amenable to the jurisdiction of the ordinary tribunals" [15]
The third is that the general ideas and principles that the constitution supports arise directly from the judgements and precedents issued by the judiciary. "We may say that the constitution is pervaded by the rule of law on the ground that the general principles of the constitution... are with us the result of judicial decisions determining the rights of private persons in particular cases brought before the courts" [16]
Separation of powers is often regarded as a second limb functioning alongside the rule of law to curb the powers of the government. In many modern nation states, power is divided and vested into three branches of government: The legislature, the executive, and the judiciary are known as the horizontal separation of powers. The first and the second are harmonized in traditional Westminster system. [17] Vertical separation of powers is decentralization.
Election law is a subfield of constitutional law. It includes the rules governing the process of elections. These rules 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.
A constitution is the aggregate of fundamental principles or established precedents that constitute the legal basis of a polity, organization or other type of entity, and commonly determines how that entity is to be governed.
Marbury v. Madison, 5 U.S. 137 (1803), was a landmark decision of the U.S. Supreme Court that established the principle of judicial review, meaning that American courts have the power to strike down laws and statutes they find to violate the Constitution of the United States. Decided in 1803, Marbury is regarded as the single most important decision in American constitutional law. It established that the U.S. Constitution is actual law, not just a statement of political principles and ideals. It also helped define the boundary between the constitutionally separate executive and judicial branches of the federal government.
The legal system of Canada is pluralist: its foundations lie in the English common law system, the French civil law system, and Indigenous law systems developed by the various Indigenous Nations.
The Constitution of the Republic of Lithuania defines the legal foundation for all laws passed in the Republic of Lithuania. The first constitution of the contemporary republic was enacted on 1 August 1922. The current constitution was adopted in a referendum on 25 October 1992.
In the United States, state law refers to the law of each separate U.S. state.
The legal system of Australia has multiple forms. It includes a written constitution, unwritten constitutional conventions, statutes, regulations, and the judicially determined common law system. Its legal institutions and traditions are substantially derived from that of the English legal system, which superseded Indigenous Australian customary law during colonisation. Australia is a common-law jurisdiction, its court system having originated in the common law system of English law. The country's common law is the same across the states and territories.
The Constitution of the Republic of Singapore is the supreme law of Singapore. A written constitution, the text which took effect on 9 August 1965 is derived from the Constitution of the State of Singapore 1963, provisions of the Federal Constitution of Malaysia made applicable to Singapore by the Republic of Singapore Independence Act 1965, and the Republic of Singapore Independence Act itself. The text of the Constitution is one of the legally binding sources of constitutional law in Singapore, the others being judicial interpretations of the Constitution, and certain other statutes. Non-binding sources are influences on constitutional law such as soft law, constitutional conventions, and public international law.
Entick v Carrington [1765] EWHC KB J98 is a leading case in English law and UK constitutional law establishing the civil liberties of individuals and limiting the scope of executive power. The case has also been influential in other common law jurisdictions and was an important motivation for the Fourth Amendment to the United States Constitution. It is famous for the dictum of Lord Camden: "If it is law, it will be found in our books."
Australian administrative law defines the extent of the powers and responsibilities held by administrative agencies of Australian governments. It is basically a common law system, with an increasing statutory overlay that has shifted its focus toward codified judicial review and to tribunals with extensive jurisdiction.
In the United States, judicial review is the legal power of a court to determine if a statute, treaty, or administrative regulation contradicts or violates the provisions of existing law, a State Constitution, or ultimately the United States Constitution. While the U.S. Constitution does not explicitly define the power of judicial review, the authority for judicial review in the United States has been inferred from the structure, provisions, and history of the Constitution.
In most legal jurisdictions, a supreme court, also known as a court of last resort, apex court, and highcourt of appeal, and court of final appeal, is the highest court within the hierarchy of courts. Broadly speaking, the decisions of a supreme court are binding on all other courts in a nation and are not subject to further review by any other court. Supreme courts typically function primarily as appellate courts, hearing appeals from decisions of lower trial courts, or from intermediate-level appellate courts. A supreme court can also, in certain circumstances, act as a court of original jurisdiction.
The law of California consists of several levels, including constitutional, statutory, and regulatory law, as well as case law. The California Codes form the general statutory law, and most state agency regulations are available in the California Code of Regulations.
Judicial review is a process under which a government's executive, legislative, or administrative actions are subject to review by the judiciary. In a judicial review, a court may invalidate laws, acts, or governmental actions that are incompatible with a higher authority. For example, an executive decision may be invalidated for being unlawful, or a statute may be invalidated for violating the terms of a constitution. Judicial review is one of the checks and balances in the separation of powers—the power of the judiciary to supervise the legislative and executive branches when the latter exceed their authority. The doctrine varies between jurisdictions, so the procedure and scope of judicial review may differ between and within countries.
The constitution of the United Kingdom comprises the written and unwritten arrangements that establish the United Kingdom of Great Britain and Northern Ireland as a political body. Unlike in most countries, no official attempt has been made to codify such arrangements into a single document, thus it is known as an uncodified constitution. This enables the constitution to be easily changed as no provisions are formally entrenched.
The law of the United States comprises many levels of codified and uncodified forms of law, of which the most important is the nation's Constitution, which prescribes the foundation of the federal government of the United States, as well as various civil liberties. The Constitution sets out the boundaries of federal law, which consists of Acts of Congress, treaties ratified by the Senate, regulations promulgated by the executive branch, and case law originating from the federal judiciary. The United States Code is the official compilation and codification of general and permanent federal statutory law.
Constitutionalism is "a compound of ideas, attitudes, and patterns of behavior elaborating the principle that the authority of government derives from and is limited by a body of fundamental law".
The royal prerogative is a body of customary authority, privilege, and immunity recognized in common law as belonging to the sovereign, and which have become widely vested in the government. It is the means by which some of the executive powers of government, possessed by and vested in a monarch with regard to the process of governance of the state, are carried out.
The concept of the separation of powers has been applied to the United Kingdom and the nature of its executive, judicial and legislative functions. Historically, the apparent merger of the executive and the legislature, with a powerful Prime Minister drawn from the largest party in parliament and usually with a safe majority, led theorists to contend that the separation of powers is not applicable to the United Kingdom. However, in recent years it does seem to have been adopted as a necessary part of the UK constitution.
The rule of law is one of the longest established common law fundamental principles of the governance of the United Kingdom, dating to Magna Carta of 1215, particularly jurisprudence following its late 13th century re-drafting. At a minimum, it subjects an otherwise absolute monarch (executive) and all free people within its jurisdictions, primarily those of England and Wales, Scotland and Northern Ireland, to legal doctrines known as the general principles of law. It has evolved to work only alongside equal application of the law to all free people 'equality before the law' and within the framework of the constitutional monarchy supports the legal doctrine of parliamentary sovereignty. Exactly what it entails beyond this and the way that different aspects of the rule of law principle are applied, depends on the specific situation and era.
The Separation of powers in Singapore is governed by Constitution of the Republic of Singapore, which splits the power to govern the country between three branches of government – the parliament, which makes laws; the executive, which executes them; and the judiciary, which enforces them. Each branch, while wielding legitimate power and being protected from external influences, is subject to a system of checks and balances by the other branches to prevent abuse of power. This Westminster constitutional model was inherited from the British during Singapore's colonial years.
In modern usage, common law is contrasted with a number of other terms. First, in denoting the body of judge-made law based on that developed in England... [P]erhaps most commonly within Anglo-American jurisdictions, common law is contrasted with statutory law ...
1. The body of law derived from judicial decisions, rather than from statutes or constitutions; CASE LAW [contrast to] STATUTORY LAW.
