Inside the interdisciplinary field of Jurilinguistics, the main research has been carried out on state languages like English, French, German or Spanish. However, there is a new reality in today´s world, namely the existence of minority languages that have arisen to an official status as sub-state languages for the law and a limited range of branches of the law to be the own way to express themselves. The jurilinguistical point of view of this new reality requires a new approach to (...) it, mainly focused on both a general framework and the situation of each language. This is the reason for a first attempt to formulate a jurilinguistical general framework and a methodological approach to this new field in combination with the study of a particular case language, the Basque language, in order to describe its characters as a sub-state tool for expressing the Basque law and bijuralism, in accordance with its status as an official language in the Basque Autonomous Community and Navarrese Community, both in the Kingdom of Spain.
