The Online Legal Database (Internetowy System Aktów Prawnych – ISAP) is accessible from the webpage of the Sejm (the lower chamber of the Polish Parliament). It comprises regularly updated texts of the legal acts, published either in the Official Journal of Laws of the Republic of Poland, (Dziennik Ustaw) or the Polish Monitor (Monitor Polski) together with their bibliographic notices. The ISAP database does not comprise however the local government law nor the internal law). Since January 1st, 2012 the Official Journal as well as the Polish Monitor are available in an electronic version.
The legal acts – both the promulgated and the consolidated texts – are published in the ISAP database as PDF files. Only legal acts published in the Official Journal or the Polish Monitor constitute a legitimate source of law in Poland. Therefore, the electronic versions of legal acts available from the database shall be regarded just as informative materials. Those publications do not constitute a legitimate source of law in Poland.
The sources of Polish law are divided into two categories, i.e. the universally binding law and the internal law.
