In English law, natural justice is technical terminology for the rule against bias and the right to a fair hearing. While the term natural justice is often retained as a general concept, it has largely been replaced and extended by the general "duty to act fairly".
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 doctrine of legitimate expectation was first developed in English law as a ground of judicial review in administrative law to protect a procedural or substantive interest when a public authority rescinds from a representation made to a person. It is based on the principles of natural justice and fairness, and seeks to prevent authorities from abusing power.
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.
The Administrative Appeals Tribunal (AAT) is an Australian tribunal that conducts independent merits review of administrative decisions made under Commonwealth laws of the Australian Government. The AAT review decisions made by Australian Government ministers, departments and agencies, and in limited circumstances, decisions made by state government and non-government bodies. They also review decisions made under Norfolk Island laws. It is not a court and not part of the Australian court hierarchy; however, its decisions are subject to review by the Federal Court of Australia and the Federal Circuit Court of Australia. The AAT was established by the Administrative Appeals Tribunal Act 1975 and started operation in 1976.
Plaintiff S157/2002 v Commonwealth, also known as 'S157', is a decision of the High Court of Australia.
Errors as to precedent facts, sometimes called jurisdictional facts, in Singapore administrative law are errors committed by public authorities concerning facts that must objectively exist or not exist before the authorities have the power to take actions or make decisions under legislation. If an error concerning a precedent fact is made, the statutory power has not been exercised lawfully and may be quashed by the High Court if judicial review is applied for by an aggrieved person. The willingness of the Court to review such errors of fact is an exception to the general rule that the Court only reviews errors of law.
Administrative law in Singapore is a branch of public law that is concerned with the control of governmental powers as exercised through its various administrative agencies. Administrative law requires administrators – ministers, civil servants and public authorities – to act fairly, reasonably and in accordance with the law. Singapore administrative law is largely based on English administrative law, which the nation inherited at independence in 1965.
Procedural impropriety in Singapore administrative law is one of the three broad categories of judicial review, the other two being illegality and irrationality. A public authority commits procedural impropriety if it fails to properly observe either statutory procedural requirements, or common law rules of natural justice and fairness.

Jurisdictional error is a concept in administrative law, particularly in the UK and Australia. Jurisdiction is the "authority to decide", and a jurisdictional error occurs when the extent of that authority is misconceived. Decisions affected by jurisdictional error can be quashed by judicial review. Examples of jurisdictional errors include asking a wrong question, ignoring relevant material, relying on irrelevant material, and breaching natural justice.
