This article aims to review a new commentary to the Public Finance Act, published in mid-2014., and prepared under the editorship of the specialists from the Sejm Bureau of Research. The originality of this review lies in its interdisciplinary perspective: in addition to the typical legal-dogmatic analysis, the subsequent articles of the Act are accompanied by comprehensive economic and statistical interpretation. The author of the review highlights the practical character of the commentary and its usefulness to those who are engaged in the issues of public finances, as well as the innovative nature of financial comments, distinguishing the book from similar publications. He points out the problems related to the entry into force of the new European System of Accounts (ESA 2010) which, due to the date on which the publication appeared, was presented only to a limited extent.
