In a previously published article (Przegląd Sejmowy No. 5(142)/2017) the authors proposed definitions of the following concepts: normativity, redundancy and uselessness of a legal text. The article provides a typological review of Polish legal texts. The authors analysed the basic units of the integral (articulated) part of normative acts, i.e. legal provisions, showing their normativity, redundancy, and uselessness. The analyse includes: internal preambles, provisions describing the object and subject scope of the act, legal principles, programme and task provisions, meliorative provisions, emendations, permanently unrealisable regulations, legal definitions. The analyses led to identification of four basic types of errors in legal provisions, which were named: “doubles”, “widows”, “orphans”, and “botches”. In their closing remarks, the authors signalled the need to supplement the analysis with a description of non-integral (non-articulated) parts of normative acts. Another part of the study, devoted to these problems, is currently being prepared.
