In United States constitutional law, a regulatory taking occurs when governmental regulations limit the use of private property to such a degree that the landowner is effectively deprived of all economically reasonable use or value of their property. Under the Fifth Amendment to the United States Constitution governments are required to pay just compensation for such takings. The amendment is incorporated to the states via the Due Process Clause of the Fourteenth Amendment.
City of Boerne v. Flores, 521 U.S. 507 (1997), was a landmark decision of the Supreme Court of the United States concerning the scope of Congress's power of enforcement under Section 5 of the Fourteenth Amendment. The case also had a significant impact on historic preservation.
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 writing 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. This United States form of separation of powers is associated with a system of checks and balances.
The Constitution of Finland is the supreme source of national law of Finland. It defines the basis, structures and organisation of government, the relationship between the different constitutional organs, and lays out the fundamental rights of Finnish citizens, and individuals in general. The original Constitution Act was enacted in 1919, soon after Finland declared its independence in 1917. The current draft of the Constitution came into force on 1 March 2000.

Crotty v. An Taoiseach was a landmark 1987 decision of the Irish Supreme Court which found that Ireland could not ratify the Single European Act unless the Irish Constitution was first changed to permit its ratification. The case, taken by Raymond Crotty formally against the Taoiseach, directly led to the Tenth Amendment of the Constitution of Ireland and established that significant changes to European Union treaties required an amendment to the Irish constitution before they could be ratified by Ireland. As a consequence, the Republic of Ireland, uniquely in the EU, requires a plebiscite for every new, or substantive change to a, European Union Treaty.
Calder v. Bull, 3 U.S. 386 (1798), is a United States Supreme Court case in which the Court decided four important points of constitutional law.
There are three general sources of Singapore law: legislation, judicial precedents, and custom.
The primacy of European Union law is a legal principle establishing precedence of European Union law over conflicting national laws of EU member states. The principle was derived from an interpretation of the European Court of Justice, which ruled that European law has priority over any contravening national law, including the constitution of a member state itself. The majority of national courts have generally recognized and accepted this principle, except for the part where European law outranks a member state's constitution. As a result, national constitutional courts have also reserved the right to review the conformity of EU law with national constitutional law.
Citizenship of Russia is regulated by the Federal Act regarding citizenship of the Russian Federation, by the Constitution of the Russian Federation, and by the international treaties that cover citizenship questions and to which the Russian Federation is a party. In accordance with the supremacy clause of the Constitution, international treaties of the Russian Federation have precedence over Russian domestic law.
Judicial review is a process under which executive or legislative 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.
Block v. Hirsh, 256 U.S. 135 (1921), is a United States Supreme Court case which upheld a temporary rent control law in the District of Columbia. It set a precedent in American law that government can regulate housing conditions during times of emergency to maintain or improve living conditions.

Government of the Republic of South Africa and Others v Grootboom and Others is an important case in South African law, heard in the Constitutional Court on 11 May 2000, with judgment handed down on 4 October.
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.

South African environmental law describes the legal rules in South Africa relating to the social, economic, philosophical and jurisprudential issues raised by attempts to protect and conserve the environment in South Africa. South African environmental law encompasses natural resource conservation and utilization, as well as land-use planning and development. Issues of enforcement are also considered, together with the international dimension, which has shaped much of the direction of environmental law in South Africa. The role of the country's Constitution, crucial to any understanding of the application of environmental law, also is examined. The National Environmental Management Act (NEMA) provides the underlying framework for environmental law.
South African administrative law is the branch of public law in that country 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."
Dawood v Minister of Home Affairs is an important case in South African law, particularly in the areas of constitutional litigation, constitutional law and immigration law. The applicants were South African citizens and their spouses, who were neither citizens nor permanent residents of South Africa. The case examined the constitutional right of spouses to cohabit and the need for Parliament, when granting government officials powers that touch on constitutional rights, to lay down proper guidelines.
