The Model Law is the successful product of a long and gradual process of harmonisation of arbitration laws: its provisions are a selective and inventivesynthesis of features inspired by numerous influences. This legislative archetype has also been the direct source of many laws which, while not replicating it entirely, have been evidently inspired by its spirit and textual approach. Until July 2015, legislation based on the Model Law had been adopted in 69 States in a total of 99 jurisdictions. UNCITRAL has not established minimum requirements for ascertaining when a country can be said to have enacted the Model Law. Generally domestic arbitration legislation is considered to be an enactment of the Model Law when it is evident that the legislator took the Model Law as a basis and made certain amendments and additions, but did not simply use the Model Law as one amongst other legislative models or simply follow 'its principles'.
