Article 124 states the main principles of decentralisation: provinces and municipalities are competent to regulate and administrate their internal affairs (Subarticle 1), delegation is possible — but only by the provinces and municipalities themselves (Article 128); nevertheless demands, regulated by formal law, can be made by the central government on such regulative and administrative powers; delegation is allowed (Article 124 sub 2). So the lower territorial administrative bodies have on the one hand a relative autonomy — but on the other hand they must work within the national legal framework, loyally implement national government policy and are subject to central control. This is further covered by Article 132: the standard organisation of provinces and municipalities and the composition and competence of their administrative organs is regulated by formal law (Subarticle 1); how they are controlled is regulated by law (Subarticle 2); their decisions shall only be subject to prior supervision in cases determined by law or by force of law (Subarticle 3); their decisions shall only be quashed by Royal Decree and on grounds that they violate the law (in the broadest sense: the "recht") or conflict with the public interest (Subarticle 4). Law will in general regulate the kind of provisions to be made if provinces or municipalities fail to meet the demands of Article 124 sub 2 (Subarticle 5). Which taxes may be levied by provinces and municipalities and their financial relationship with the state, are determined by law (Subarticle 6).
