This article is a review of the Financial Law textbook edited by V.F. Popondopulo and D.A. Petrov. The article critically assesses the provisions of the textbook, that confound the fundamentals of the financial law of the Russian Federation. The superficial analysis of the fundamental financial law categories, the absence of knowledge of the history of development of financial law as well as the absence of due research of the system of legal regulation of public relations established in the course of functioning of the financial market has led the authors of the textbook to incorrect conclusions. It is concluded that in general the textbook under review is superficial, it does not take into account the basic provisions of the national theory of financial law and intentional negligence of research of the leading representatives of true science of financial law together with incomplete author standpoints is a challenge for the whole scientific community and representatives of the financial law science in particular
