Administrative law is a division of law governing the activities of executive branch agencies of government. Administrative law includes executive branch rule making, adjudication, and the enforcement of laws. Administrative law is considered a branch of public law.
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.
Separation of powers refers to the division of a state's government into "branches", each with separate, independent powers and responsibilities, so that the powers of one branch are not in conflict with those of the other branches. The typical division into three branches of government, sometimes called the trias politica model, includes a legislature, an executive, and a judiciary. It can be contrasted with the fusion of powers in monarchies, but also parliamentary and semi-presidential systems where there can be overlap in membership and functions between different branches, especially the executive and legislative.
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.
The United Kingdom has three legal systems, each of which derives from a particular geographical area for a variety of historical reasons: English and Welsh law, Scots law, Northern Ireland law, and, since 2007, calls for a fourth type that of purely Welsh law as a result of Welsh devolution, with further calls for a Welsh justice system.
Separation of powers is a political doctrine originating in the writings of Charles de Secondat, Baron de Montesquieu in The Spirit of the Laws, in which he argued for a constitutional government with three separate branches, each of which would have defined abilities to check the powers of the others. This philosophy heavily influenced the drafting of the United States Constitution, according to which the Legislative, Executive, and Judicial branches of the United States government are kept distinct in order to prevent abuse of power. The American form of separation of powers is associated with a system of checks and balances.
Australian constitutional law is the area of the law of Australia relating to the interpretation and application of the Constitution of Australia. Legal cases regarding Australian constitutional law are often handled by the High Court of Australia, the highest court in the Australian judicial system. Several major doctrines of Australian constitutional law have developed.
Ultra vires is a Latin phrase used in law to describe an act that requires legal authority but is done without it. Its opposite, an act done under proper authority, is intra vires. Acts that are intra vires may equivalently be termed "valid", and those that are ultra vires termed "invalid".
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. 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 separation of powers in Australia is the division of the institutions of the Australian government into legislative, executive and judicial branches. This concept is where legislature makes the laws, the executive put the laws into operation, and the judiciary interprets the laws; all independently of each other. The term, and its occurrence in Australia, is due to the text and structure of the Australian Constitution, which derives its influences from democratic concepts embedded in the Westminster system, the doctrine of "responsible government" and the United States version of the separation of powers. However, due to the conventions of the Westminster system, a strict separation of powers is not always evident in the Australian political system, with little separation between the executive and the legislature, with the executive required to be drawn from, and maintain the confidence of, the legislature; a fusion.
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.
French law has a dual jurisdictional system comprising private law, also known as judicial law, and public law.
In most legal jurisdictions, a supreme court, also known as a court of last resort, apex court, and highcourt of appeal, is the highest court within the hierarchy of courts. Broadly speaking, the decisions of a supreme court 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.
The persona designata doctrine is a doctrine in law, particularly in Canadian and Australian constitutional law which states that, although it is generally impermissible for a federal judge to exercise non-judicial power, it is permissible for a judge to do so if the power has been conferred on the judge personally, as opposed to powers having been conferred on the court. The doctrine in the more general sense has been recognised throughout the common law countries. Persona designata, according to Black's Law Dictionary, means "A person considered as an individual rather than as a member of a class"; thus it may be a person specifically named or identified in a lawsuit, as opposed to the one belonging to an identified category or group. While it has its origin in Montesquieu's doctrine of the separation of powers, it can be traced back as far as Aristotle's Politics.
The legal system of Azerbaijan is based on civil law. As the country was a republic of the Soviet Union until 1991, its legal history has also been influenced heavily by socialist law. However, after the collapse of the Soviet Union, Azerbaijan became independent by enactment of the constitutional act of national independence on October 18, 1991. Azerbaijan started reformation of the legal system by the establishing of democratic reforms. This was followed by the adoption of the first Constitution in 1995 which is the foundation of the legislative system of the modern country. The Constitution creates the system of presidential republic with a separation of powers among the Legislative, Executive and Judicial branches of the government in order to prevent abuse of power.
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 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.
South African administrative law is the branch of public law which regulates the legal relations of public authorities, whether with private individuals and organisations or with other public authorities, or better say, in present-day South Africa, which regulates "the activities of bodies that exercise public powers or perform public functions, irrespective of whether those bodies are public authorities in a strict sense." According to the Constitutional Court, administrative law is "an incident of the separation of powers under which the courts regulate and control the exercise of public power by the other branches of government."
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.
Primary legislation and secondary legislation are two forms of law, created respectively by the legislative and executive branches of governments in representative democracies. Primary legislation generally consists of statutes, also known as 'acts', that set out broad principles and rules, but may delegate specific authority to an executive branch to make more specific laws under the aegis of the principal act. The executive branch can then issue secondary legislation, creating legally enforceable regulations and the procedures for implementing them.
