In the municipalities that are majority Basque-speaking in terms of their sociolinguistic reality, we have analysed the legislation in force enabling Basque to be the language of work. Specifically, the language that has to be used in the Administrations located in the Basque Autonomous Community has been analysed. So, from the starting point of the distribution of powers in Spain, the legislation in force in the sphere of the local administrations in the State and in the Basque Autonomous Community has been analysed. That was followed by an analysis of the following aspects: Constitutional Jurisprudence and the evolution in the Jurisprudence of the ordinary courts; the legal bases existing for the administrations located in the Basque Autonomous Community to use Basque with legal force and effect in their relations with each other; and the formulas used by other autonomous communities (regions) to deal with the same legal problems. As we have concluded from all this that Basque needs a new regulation on a level of law, we have put forward contributions to the draft Municipal Law to reflect on the possible solutions to these problems.
Errealitate soziolinguistikoaren arabera gehien euskalduna duten udalerrietan, lan hizkuntza euskara izateko, indarrean dagoen Legediaren azterketa bat egin dugu. Bereziki, EAEn kokaturiko Administrazioen artean, erabili beharreko hizkuntza aztertu da. Horretarako, Espainia eskumen banaketatik abiatuta, Estatuan eta Euskadiko Erkidego Autonomikoan, toki administrazio eremuan indarrean dagoen Legedia aztertu dira. Ondoren, Jurisprudentzia Konstituzionala eta Auzitegi arruten Jurisprudentziaren eboluzioa aztertu da. Jarraian, EAEn, kokaturiko administrazioek, euren arteko harremanetan, euskara balio eta eraginkortasun juridikoz erabiltzeko dauden oinarri juridikoak aztertu dira eta ondoren, arazo juridiko berdinei aurre egiteko, beste autonomia erkidegoek erabilitako formulak. Guzti honetatik, euskarak Lege mailako arau berri baten beharra duela ondorioztatu dugunez, Udal Lege proiektuaren ezarpenak mahai gaineratu ditugu arazo hauek gainditu ditzakeen hausnartzeko.
