Regulation mandated by a state attempts to produce outcomes which might not otherwise occur, produce or prevent outcomes in different places to what might otherwise occur, or produce or prevent outcomes in different timescales than would otherwise occur. Common examples of regulation include attempts to control market entries, prices, wages, pollution effects, employment for certain people in certain industries, standards of production for certain goods, the military forces and services. The economics of imposing or removing regulations relating to markets is analysed in regulatory economics.
An implementing regulation (in democratic systems using laws as the basis for state action) is adopted by a public administration regulatory agency. In some national venues, there may be further review, as by an Office of Administrative Law (OAL). In countries with well established judicial systems, the regulation will be subject to judicial review, on challenge by a party having standing to bring an action ('standing' is usually interpreted to mean being adversely affected).
A regulation is a form of secondary legislation which is used to implement a primary piece of legislation appropriately, or to take account of particular circumstances or factors emerging during the gradual implementation of, or during the period of, a primary piece of legislation.
Other forms of secondary legislation are statutory instruments, statutory orders, by-laws and rules. Some of these (but not all of them) need to be referred back before being implemented, to the primary legislative process.
Regulations are justified using a variety of reasons and therefore can be classified in several broad categories:
The second half of the 20th Century saw a wave of attempts to modify some existing regulatory structures and systematize the creation and review of new ones. A part of this was the deregulation movement.
A parallel development with 'deregulation' has been organized, ongoing programs to review regulatory initiatives with a view to minimizing, simplifying, and making more cost effective regulations. Such efforts, given impetus by the Regulatory Flexibility Act of 1980 in the United States, are embodied in the United States Office of Management and Budget's Office of Information and Regulatory Affairs, and the United Kingdom's Better Regulation Commission. Cost-benefit analysis is frequently used in such reviews. In addition, there have been regulatory innovations, usually suggested by economists, such as emissions trading. Academic research on wedding economic theory with regulatory activity continues.
From other point of view, liberalization does not always imply deregulation, but more players in the Market (desoligolipolization).
In that primary legislation there are provisions to allow local authorities to legislate for themselves, within reason and under proper process, on a range of matters in their areas of responsibility. This allows the law to be effectively applied with appropriate flexibility and taking account of local factors. These are often best known by the local authority concerned.
Regulations also assist the primary legislative process, the national parliament, to avoid the potential bottleneck of the detailed implementation of all the laws it produces in all the varying circumstances throughout the land or throughout the process of their implementation.
Since 1997, central government has been working to improve regulation by applying new principles of better regulation.
All legislation and regulation issued by the executive, including ordinances not ratified by the legislative branch, is subject to judicial review by the administrative courts, such as the Conseil d'État.
Other forms of legislative acts of the European Union (EU) are directives, decisions, recommendations and opinions.
