Sui generis
From Wikipedia, the free encyclopedia
Sui generis (English pronunciation (IPA): /ˌsuːiˈdʒɛnərɪs/, roughly "SOO-ee JEN-er-ihs", Latin pronunciation: /ˌsuːiˈgeneris/) is a Neo-Latin expression, literally meaning of its own kind/genus or unique in its characteristics.[1] The expression was effectively created by scholastic philosophy to indicate an idea, an entity or a reality that cannot be included in a wider concept.[citation needed] In the structure "genus → species" a species that heads its own genus is sui generis. This does not, however, mean that all genera with only a single member are composed of sui generis species. It is only if the genus was specifically created to refer to that one species, with no other known examples, that the species is sui generis. If the species is alone merely due to extinction, as in the case of the Homo genus, the surviving species is not sui generis, because other members of the genus are known, even if they are not currently alive.

[edit] Legal applications
In law, it is a term of art used to identify a legal classification that exists independently of other categorizations because of its uniqueness or due to the specific creation of an entitlement or obligation. Courts have used the term in describing cooperative apartment corporations, mostly because this form of housing is considered real property for some purposes and personal property for other purposes. In intellectual property there are rights which are known as being sui generis to owners of a small class of works, such as intellectual property rights in mask works, ship hull designs, databases, or plant varieties. When referring to case citations and authorities, lawyers (and Judges) may refer to an authority cited as being 'sui generis', meaning in that context, it is one confined (or special) to its own facts, and therefore may not be of broader application.
[edit] Statutory
In statutory interpretation, it refers to the problem of giving meaning to groups of words where one of the words is ambiguous or inherently unclear. For example, in criminal law, a statute might require a mens rea element of "unlawful and malicious" intent. Whereas the word "malicious" is well-understood, the word "unlawful" in this context is less clear. Hence, it must be given a meaning of the "same kind" as the word of established meaning.
This is particularly the case when the two or more words are conjoined, linked by the word "and", as opposed to placed in a disjunctive relationship, linked by the word "or". The interpretation of the two or more words might be different depending on the circumstances. Courts sometimes have to attribute a conjunctive (X and Y) intention to the legislature even though the list is disjunctive (X or Y) because, otherwise, no overall interpretation of the law in question would make sense.
[edit] Town planning
In British town planning law, certain uses of land are labeled sui generis to indicate that they are not covered by a 'Use Class' – effectively in a class of their own. Change of use of land within a Use Class does not require planning permission; however, changing between certain Use Classes, or any change of use of sui generis land, requires planning permission. Examples of sui generis use (identified in the Use Classes Order 1987) include theatres, amusement arcades, laundrettes, taxi or vehicle hire businesses, petrol filling stations, scrapyards, nightclubs, motor car showrooms, retail warehouses, clubs and hostels.
[edit] Aboriginal law
The term has also been used in the context of Canadian aboriginal law to describe the nature of aboriginal title.
[edit] Political science
In political science, the unparalleled development of the European Union as compared to other international organizations has led to its designation as a sui generis geopolitical entity. There has been widespread debate over the legal nature of the EU given its mixture of intergovernmental and supranational elements, with the organisation thus possessing some characteristics common to confederal and federal entities.
A similar case which has led to the use of the label sui generis is the unique relationship between France and New Caledonia, since the legal status of New Caledonia can aptly be said to lie "somewhere between an overseas collectivity and a sovereign nation". Whereas there are perhaps other examples of such a status for other disputed or dependent territories, this arrangement is certainly unique within the French Republic.
The old Holy Roman Empire may also fit under this category for its unique organization and place in European history.
In local government, a sui generis entity is one which does not fit with the general scheme of local governance of a country. For example in England, the City of London and the Isles of Scilly are the two sui generis localities, as their forms of local government are both very different from those of elsewhere in the country (for historical and geographical reasons).
[edit] Sociology
In the sociology of Emile Durkheim, sui generis is used to illustrate his theories on social existence. Durkheim states that the main object of sociology is to study social facts. These social facts can only be explained by other social facts. They have a meaning of their own and cannot be reduced to psychological or biological factors. Social facts have a meaning of their own, they are 'sui generis'. Durkheim states that when one takes an organization and replaces some individuals with some others, the essence of the organization does not (necessarily) change. It can happen, for example, that over the course of a few decades, the entire staff of an organisation is replaced, while the organisation retains its distinctive character. Durkheim does not limit this thought to organisation, but extends it to the whole society: he maintains that society, as it was there before any living individual was born, is independent of all individuals. His sui generis (its closest English meaning in this sense being 'independent') society will furthermore continue its existence after the individual ceases to interact with it.
