De facto is a Latin expression that means "concerning fact". In law, it is meant to mean "in practice but not necessarily ordained by law" or "in practice or actuality, but without being officially established". It is commonly used in contrast to de jure (which means "concerning the law") when referring to matters of law, governance, or technique (such as standards) that are found in the common experience as created or developed without or contrary to a regulation. When discussing a legal situation, de jure designates what the law says, while de facto designates action of what happens in practice. It is analogous and similar to the expressions "for all intents and purposes" or "in fact". The term de facto as of governments was created after the Argentine Constitution referred to illegal governments (governing bodies which Argentina did not acknowledge as individual nations) as de facto governments. The term de facto may also be used when there is no relevant law or standard, but a common and well established practice that is considered the accepted norm.
Segregation (during Civil Rights Era)
De Facto is a term pertaining to racial discrimination or segregation that was present during the fifties and sixties. This term was simply discrimination that was NOT segregation by law (de jure). Blacks riding in the back of the bus, blacks having to step aside onto the street if not enough room was present for a white person to walk down a sidewalk without running into a black person, and separate but equal facilities are considered to be de facto segregation.
A de facto standard is a standard (formal or informal) that has achieved a dominant position, by tradition, enforcement, or market dominance. It has not necessarily received formal approval by way of a standardization process, and may not be an official standard document.
Several de factoEnglish-speaking countries have no de jure official national language. In New Zealand, there are three official languages (English, Maori and sign). In the United States, forty nine states have declared English the official language, with Hawaii using Hawaiian and English as official languages. However, two U.S. states also have de facto second languages: Spanish in New Mexico and French in Louisiana.
Similarly, in the former Soviet Union, Russian was the official language de facto, but not de jure. Sweden is another example of a country with no language recognized de jure.
Lebanon and Morocco are two examples where the official language is Arabic but an additional de facto language is considered to be French.
A de facto government is a government wherein all the attributes of sovereignty have, by usurpation, been transferred from those who had been legally invested with them to others, who, sustained by a power above the forms of law, claim to act and do really act in their stead.
In politics, a de facto leader of a country or region is one who has assumed authority, regardless of whether by lawful, constitutional, or legitimate means; very frequently the term is reserved for those whose power is thought by some faction to be held by unlawful, unconstitutional, or otherwise illegitimate means, often by deposing a previous leader or undermining the rule of a current one. De facto leaders need not hold a constitutional office, and may exercise power in an informal manner.
Not all dictators are de facto rulers. For example, Augusto Pinochet of Chile initially came to power as the chairperson of a military junta, which briefly made him de facto leader of Chile, but then he later amended the nation's constitution and made himself president for life, making him the formal and legal ruler of Chile. Similarly, Saddam Hussein's formal rule of Iraq is often recorded as beginning in 1979, the year he assumed the Presidency of Iraq. However, his de facto rule of the nation began at an earlier date—during his time as vice president he exercised a great deal of power at the expense of the elderly, legal ruler, Ahmed Hassan al-Bakr.
Some notable true de facto leaders have been Deng Xiaoping of the People's Republic of China and General Manuel Noriega of Panama. Both of these men exercised near-total control over their respective nations for many years, despite not having either legal constitutional office or the legal authority to exercise power. These individuals are today commonly recorded as the "leaders" of their respective nations; recording their legal, correct title would not give an accurate assessment of their power. Terms like strongman or dictator are often used to refer to de facto rulers of this sort.
The de facto boundaries of a country are defined by the area that its government is actually able to enforce its laws in, and to defend against encroachments by other countries that may also claim the same territory de jure. The line of control in Kashmir is an example of a de facto boundary. As well as cases of border disputes, de facto boundaries may also arise in relatively unpopulated areas when the border was never formally established, or when the agreed border was never surveyed and its exact position is unclear. The same concepts may also apply to a boundary between provinces or other subdivisions of a federal state.
Similarly, a nation with de facto independence, like Somaliland, is one that is not recognized by other nations or by international bodies, even though it has its own government that exercises absolute control over its claimed territory.
Social sciences and other usages
A de factomonopoly is a system where many suppliers of a product are allowed, but the market is so completely dominated by one that the others might as well not exist. (Similarly for related terms such as "oligopoly" and "monopsony".) This is the type of situation that antitrust laws are intended to eliminate, when they are used.
