Las lenguas oficiales del Estado español en los textos legales, ¿fomento o reconocimiento del plurilingüismo?

[EN] The use of different languages within the same geographical area usually generates different opinions about how these should be controlled within public ambits, such as education, media or public administration. Our main goal is to provide an analysis of the existing points of view with regard to the use of Spanish and the other co-official languages in Spain, stressing the legal framework that justifies them, as well as their underlying objectives and possible consequences. Our intention is to discuss if these texts are aimed to simply recognize the official character of two languages or if they pursue the development of a linguistic planning that guarantees the use of both within the public ambit.
