This marks a delineation of states that are able to ensure preservation of interests, there has to be some mutually beneficial reasoning behind the formal or informal preservation of interests. In the Union creating the United Kingdom of Great Britain and Ireland in 1801, no such guarantee was given for the laws and courts of the Kingdom of Ireland, though they were continued as a matter of practice. The informal recognition of such interests represents the different circumstances of the two Unions, the small base of institutional power in Ireland at the time (those who were the beneficiaries of the Protestant Ascendancy) had faced a revolution in the Irish Rebellion of 1798, and as a result there was an institutional drive toward unification, limiting the Irish negotiating power. However, informal guarantees were given to preclude the possibility of further Irish unrest in the period following the French Revolution of 1789 and the 1798 rebellion. These types of informal arrangements are more susceptible to changes, for example Tyrol was guaranteed that its Freischütz companies would not be posted to fight outside Tyrol without their consent, a guarantee later revoked by the Austrian republic. This can be juxtaposed with the continued existence of the Scottish Parliament and a separate body of Scottish Law distinct from English Law.
