The theory of rational lawgiver entails an assumption of normativeness of legal text. The assumption is usually presented in two propositions: (1) articulated parts of legal text are normative, and (2) other parts of legal text (i.e. preambles, titles of acts, parts, chapters etc.) are not normative. A series of theoretical, legislative and constitutional arguments are presented for the modification of this assumption. The whole legal next is normative. Every part and every sentence of legal text may express legal norm, including preamble. Thus one may speak about presumption of normativeness of the whole legal text. This presumption can be repealed.
