Data ustawy

This article is devoted to issues related to the determination of the date of a statute. Even though these issues are regulated in the provisions concerning the drafting of legal texts, it is not done in a comprehensive manner. The article indicates, in particular, the functions of the date of a statute (informative, identification and legislative). The main part of the article, however, is devoted to the rules determining the date of a statute. It is essential to identify the legal events that determine the final content of the law and its date. The article discusses the constitutionally based scenarios of legislative proceedings, during which such events occur (adoption of an act by the Parliament, the adoption of the Senate's amendments, the activities of the President related to the questioning of the act). The legislative practice in this field is analysed as well. The conclusions focus on the need to make clear what is meant by the final determination of the content of the act and to maintain consistency in determining its date.
