Historical Usage: United Kingdom: Whilst some local authorities have parks constabularies, their officers are attested as constables, not parks constables. Legislation exists that allows for some roles to have the powers of constable, yet not be sworn in as such. Prison Officers have the power of a constable when on duty, although this is rarely used. Water Bailiffs, whom check fishing permits and enforce some wildlife law also have such a privilege. The Serious Organised Crime Agency (SOCA) can also designate their officers with the power of a constable and many police officers that joined the agency when it was formed were immediately given such a designation. Being given the power of a constable would allow such individuals to carry batons and other protective equipment provided by their employing agencies. Historical usage: (6) Other European nations: The position of hereditary constable persists in some current or former monarchies of Europe. The position of Lord High Constable of Scotland is hereditary in the family of the Earl of Erroll. There is also a hereditary constable of Navarre in Spain; this position is presently held by the Duchess of Alba. Historically, many other hereditary constables existed as officers of state in former monarchies. Examples are the Constable of Castile (Condestable de Castilla) and the Constable of Portugal (Condestável do Reino)
