Falsifiability is a deductive standard of evaluation of scientific theories and hypotheses, introduced by the philosopher of science Karl Popper in his book The Logic of Scientific Discovery (1934). A theory or hypothesis is falsifiable if it can be logically contradicted by an empirical test.
Jurisprudence, also known as theory of law or philosophy of law, is the examination in a general perspective of what law is and what it ought to be. It investigates issues such as the definition of law; legal validity; legal norms and values; as well as the relationship between law and other fields of study, including economics, ethics, history, sociology, and political philosophy.
Common-law marriage, also known as non-ceremonial marriage, sui iuris marriage, informal marriage, de facto marriage, more uxorio or marriage by habit and repute, is a marriage that results from the parties' agreement to consider themselves married, followed by cohabitation, rather than through a statutorily defined process. Not all jurisdictions permit common law marriage, but will typically respect the validity of such a marriage lawfully entered in another state or country.
A legal custom is the established pattern of behavior within a particular social setting. A claim can be carried out in defense of "what has always been done and accepted by law".
In jurisprudence and legal philosophy, legal positivism is the theory that the existence of the law and its content depend on social facts, such as acts of legislation, judicial decisions, and customs, rather than on morality. This contrasts with natural law theory, which holds that law is necessarily connected to morality in such a way that any law that contradicts morality lacks legal validity.
Ronald Myles Dworkin was an American legal philosopher, jurist, and scholar of United States constitutional law. At the time of his death, he was Frank Henry Sommer Professor of Law and Philosophy at New York University and Professor of Jurisprudence at University College London. Dworkin had taught previously at Yale Law School and the University of Oxford, where he was the Professor of Jurisprudence, successor to philosopher H. L. A. Hart.
Herbert Lionel Adolphus Hart was an English legal philosopher. One of the most influential legal theorists of the 20th century, he was instrumental in the development of the theory of legal positivism, which was popularised by his book, The Concept of Law. Hart's contributions focused on the nature of law, the relationship between law and morality, and the analysis of legal rules and systems, introducing concepts such as the "rule of recognition" that have shaped modern legal thought.
The Copenhagen criteria are the rules that define whether a country is eligible to join the European Union. The criteria require that a state has the institutions to preserve democratic governance and human rights, has a functioning market economy, and accepts the obligations and intent of the European Union.
In European Union law, direct effect is the principle that Union law may, if appropriately framed, confer rights on individuals which not only the courts but also the public administration of member states of the European Union are bound to recognise and enforce.
The Concept of Law is a 1961 book by the legal philosopher H. L. A. Hart and his most famous work. The Concept of Law presents Hart's theory of legal positivism—the view that laws are rules made by humans and that there is no inherent or necessary connection between law and morality—within the framework of analytic philosophy. Hart sought to provide a theory of descriptive sociology and analytical jurisprudence. The book addresses a number of traditional jurisprudential topics such as the nature of law, whether laws are rules, and the relation between law and morality. Hart answers these by placing law into a social context while at the same time leaving the capability for rigorous analysis of legal terms, which in effect "awakened English jurisprudence from its comfortable slumbers".
Section 109 of the Constitution of Australia is the part of the Constitution of Australia that deals with the legislative inconsistency between federal and state laws, and declares that valid federal laws override inconsistent state laws, to the extent of the inconsistency. Section 109 is analogous to the Supremacy Clause in the United States Constitution and the paramountcy doctrine in Canadian constitutional jurisprudence, and the jurisprudence in one jurisdiction is considered persuasive in the others.
Conventionalism is the philosophical attitude that fundamental principles of a certain kind are grounded on agreements in society, rather than on external reality. Unspoken rules play a key role in the philosophy's structure. Although this attitude is commonly held with respect to the rules of grammar, its application to the propositions of ethics, law, science, biology, mathematics, and logic is more controversial.
In epistemology, criteria of truth are standards and rules used to judge the accuracy of statements and claims. They are tools of verification, and as in the problem of the criterion, the reliability of these tools is disputed. Understanding a philosophy's criteria of truth is fundamental to a clear evaluation of that philosophy. This necessity is driven by the varying, and conflicting, claims of different philosophies. The rules of logic have no ability to distinguish truth on their own. An individual must determine what standards distinguish truth from falsehood. Not all criteria are equally valid. Some standards are sufficient, while others are questionable.

Überseering BV v Nordic Construction Company Baumanagement GmbH (2002) C-208/00 is a European company law case, concerning the right of freedom of establishment.
Parliamentary sovereignty is an ancient concept central to the functioning of the constitution of the United Kingdom but which is also not fully defined and has long been debated. Since the subordination of the monarchy under parliament, and the increasingly democratic methods of parliamentary government, there have been the questions of whether parliament holds a supreme ability to legislate and whether or not it should.
The European Union Divorce Law Pact or Rome III Regulation, formally Council Regulation (EU) No. 1259/2010 of 20 December 2010 implementing enhanced cooperation in the area of the law applicable to divorce and legal separation is a regulation concerning the applicable law regarding divorce valid in 17 countries. The regulation dictates which law should be used in cross-border divorces, while which courts should be used is determined by the Brussels II Regulation, which is valid for all European Union countries, except Denmark. The agreement, approved by Council of the European Union on 20 December 2010, took effect in the 14 original contracting parties on 21 June 2012 and makes use of the enhanced co-operation mechanism which allows a minimum of nine EU member states to establish advanced integration or cooperation in an area within EU structures but without all members being involved.

Malone v United Kingdom [1984] ECHR 10 is a UK constitutional law case, concerning the rule of law.
A legal norm is a binding rule or principle, or norm, that organisations of sovereign power promulgate and enforce in order to regulate social relations. Legal norms determine the rights and duties of individuals who are the subjects of legal relations within the governing jurisdiction at a given point in time. Competent state authorities issue and publish basic aspects of legal norms through a collection of laws that individuals under that government must abide by, which is further guaranteed by state coercion. There are two categories of legal norms: normativity, which regulates the conduct of people, and generality, which is binding on an indefinite number of people and cases. Diplomatic and legislative immunity refers to instances where legal norms are constructed to be targeted towards a minority and are specifically only binding on them, such as soldiers and public officials.
