The constitution has a general Article 79 founding the establishment of other advisory bodies, the "permanent advisory colleges". The law regulates the organisation, composition and competence of these bodies (Subarticle 2); other competences than mere advisory ones may be attributed by law (Subarticle 3); in both cases delegation is allowed. There used to be a great many of these advisory bodies; after 1996 their number was brought back to a few to economise. The advice of all bodies indicated in Chapter 4 is in principle public; the law regulates the way it is published; delegation is allowed (Article 80); it is submitted to the States General (subarticle 2).
