Judicial reviewJudicial 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.
RegulationRegulation is the management of complex systems according to a set of rules and trends. In systems theory, these types of rules exist in various fields of biology and society, but the term has slightly different meanings according to context.
BrexitBrexit (ˈbrɛksᵻt,_ˈbrɛgzᵻt; portmanteau of "British exit") was the withdrawal of the United Kingdom (UK) from the European Union (EU) at 23:00 GMT on 31 January 2020 (00:00 1 February 2020 CET). The UK is the only sovereign country to have left the EU. The UK had been a member state of the EU or its predecessor the European Communities (EC), sometimes both at the same time, since 1 January 1973. Following Brexit, EU law and the Court of Justice of the European Union no longer have primacy over British laws.
Rule of lawThe 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.
