Sui generis
A similar case that led to the use of the label "sui generis" is the relationship of New Caledonia relative to France, because the legal status of New Caledonia can aptly be said to lie somewhere between a French overseas collectivity and a sovereign nation. Although other examples of such status for other dependent or disputed territories may exist, this arrangement is unique within the French realm.
Town and country planning in the United Kingdom
Various uses are considered to be "sui generis", meaning that they are considered to be a use class in themselves, and not part of an existing use class. These specifically include:A key part of planning control is exercised in the UK by preventing any significant development of property without permission by the local authority. In Part III of the Town and Country Planning Act 1990, under section 59 the Secretary of State delegates to public bodies the right to grant planning permission.
A long list of other unconsolidated Acts and Regulations also affect UK planning. For example, the Localism Act 2011 abolished the Infrastructure Planning Commission for national projects, set up by the Planning Act 2008 and recentralised control in the hands of the Secretary of State.
