Therefore, delegation is only allowed if articles contain the terms "regulate" or "by force of law"; otherwise it is forbidden. This rule itself, however, being legal doctrine, is not explicitly included anywhere within the written law and is only found in the official commission reports and ministerial commentaries accompanying the bill. Chapter 1 is mainly a bill of rights. There is no normative hierarchy indicated by the constitution: all basic rights are principally equal in value and importance. Some rights are absolute, most can be limited by parliamentary or "formal" law, many can be limited by delegation of limiting powers. They include:  In addition to these classic rights the revision of 1983 introduced a number of social rights. The distinction between the two categories is not strictly based on any legal doctrine and in fact the social right articles contain many freedom rights. The social rights are:   Dutch constitutional doctrine holds that the King and ministers together form the government and this indivisibly, so that the King in any of his public acts always acting under ministerial responsibility is not the Head of Government, but embodies it fully. The King "is", however, head of state, and so a special paragraph is dedicated to the King in this quality. Article 24 stipulates that there is kingship and that this kingship is held by William I of the Netherlands and his lawful successors. Articles 25 and 26 regulate the line of succession to the Dutch throne; since 1983 female successors have equal rights to the throne. Further articles regulate abdication (Article 27); parliamentary approval of royal marriage on penalty of loss of the right to the throne (Art. 28); the exclusion of unfit possible heirs (Art. 29); appointment of a successor if heirs are absent (Art. 30 and 31); the oath and inauguration in the capital of the Netherlands, Amsterdam (Art. 32); the age of royal majority at eighteen (Art. 33); guardianship over a minor King (Art. 34); declaration by Parliament of the King's inability (Art. 35); temporary relinquishment of the exercise of royal authority (Art. 36); regency (Art. 37 and 38); the membership of the Royal House (in practice mainly consisting of members of the House of Orange) (Art. 39); its payment (Art. 40) and the organisation of the royal household by the King (Art. 41). Article 42 states the main principles of Dutch government: that it is formed by King and ministers (Subarticle 1) and that "the King is inviolate; the ministers are responsible" (Subarticle 2).
