Catalunya applies the national LRBRL baseline (Ley 7/1985) together with the regional local-government law: Decret legislatiu 2/2003, Text refós de la Llei municipal i de règim local de Catalunya. The regional law extends LRBRL with autonomous community-specific provisions on council organisation, meeting procedures, and scope of municipal autonomy. Specific notice periods and public-comment provisions vary between the national floor and the regional addition; both should be captured in a quality pass. For the authoritative regional law text, consult the BOE of the relevant autonomous community (BOJA, BOA, DOGC, etc.).
