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.
Judicial independence is the concept that the judiciary should be independent from the other branches of government. That is, courts should not be subject to improper influence from the other branches of government or from private or partisan interests. Judicial independence is important for the idea of separation of powers.
Public law is the part of law that governs relations between legal persons and a government, between different institutions within a state, between different branches of governments, as well as relationships between persons that are of direct concern to society. Public law comprises constitutional law, administrative law, tax law and criminal law, as well as all procedural law. Laws concerning relationships between individuals belong to private law.

Judicial review is a process under which executive, legislative and administrative actions are subject to review by the judiciary. A court with authority for judicial review may invalidate laws, acts and governmental actions that are incompatible with a higher authority: 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 or British constitution 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 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 Supreme Court of the United Kingdom recognises that there are constitutional principles, including parliamentary sovereignty, the rule of law, democracy, and upholding international law.
The rule of law is a political ideal that all citizens and institutions within a country, state, or community are accountable to the same laws, including lawmakers and leaders. The term rule of law is closely related to constitutionalism as well as Rechtsstaat. It refers to a political situation, not to any specific legal rule. The rule of law is defined in the Encyclopedia Britannica as "the mechanism, process, institution, practice, or norm that supports the equality of all citizens before the law, secures a nonarbitrary form of government, and more generally prevents the arbitrary use of power."
A bill of rights, sometimes called a declaration of rights or a charter of rights, is a list of the most important rights to the citizens of a country. The purpose is to protect those rights against infringement from public officials and private citizens.
Wednesbury unreasonableness is a ground of judicial review in Singapore administrative law. A governmental decision that is Wednesbury-unreasonable may be quashed by the High Court. This type of unreasonableness of public body decisions was laid down in the English case of Associated Provincial Picture Houses v. Wednesbury Corporation (1947), where it was said that a public authority acts unreasonably when a decision it makes is "so absurd that no sensible person could ever dream that it lay within the powers of the authority".

Constitutional economics is a research program in economics and constitutionalism that has been described as explaining the choice "of alternative sets of legal-institutional-constitutional rules that constrain the choices and activities of economic and political agents". This extends beyond the definition of "the economic analysis of constitutional law" and is distinct from explaining the choices of economic and political agents within those rules, a subject of orthodox economics. Instead, constitutional economics takes into account the impacts of political economic decisions as opposed to limiting its analysis to economic relationships as functions of the dynamics of distribution of marketable goods and services.
The rule according to a higher law is a statement which expresses that no law may be enforced by the government unless it conforms with certain universal principles of fairness, morality, and justice. Thus, the rule according to a higher law may serve as a practical legal criterion to qualify the instances of political or economical decision-making, when a government, even though acting in conformity with clearly defined and properly enacted law, still produces results which many observers find unfair or unjust.
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".
Parliamentary sovereignty is an ancient concept central to the functioning of the constitution of the United Kingdom but which is also not fully defined and has long been debated. Since the subordination of the monarchy under parliament, and the increasingly democratic methods of parliamentary government, there have been the questions of whether parliament holds a supreme ability to legislate and whether or not it should.
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.
Section 3 of the Human Rights Act 1998 is a provision of the United Kingdom's Human Rights Act 1998 that requires courts to interpret both primary and subordinate legislation so that their provisions are compatible with the articles of the European Convention of Human Rights, which are also part of the Human Rights Act 1998. This interpretation goes far beyond normal statutory interpretation, and includes past and future legislation, therefore preventing the Human Rights Act from being impliedly repealed by subsequent contradictory legislation.
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.
Parliamentary sovereignty, also called parliamentary supremacy or legislative supremacy, is a concept in the constitutional law of some parliamentary democracies. It holds that the legislative body has absolute sovereignty and is supreme over all other government institutions, including executive or judicial bodies. It also holds that the legislative body may change or repeal any previous legislation and so it is not bound by written law or by precedent.
