A financial law enforcement act is an act issued on the basis of the current rules of financial law by the authorized bodies, establishing or determining – in respect of an individual addressee – the rights and (or) obligations in a particular case in the field of public finance, or preparing their establishment or determination.The subjects applying the norms of financial law, can be divided into: bodies of financial ad-ministration, the courts (primarily administrative courts) and quasi-judicial bodies (e.g. the Commission, considering cases of violation of discipline of public finance). The first group of bodies issues decisions and orders (financial and legal acts), the bodies of the second group issue court decisions and court orders, the bodies of the third group issue decisions.The role of administrative courts in the financial law enforcement is significant. Significant number of financial cases, particularly concerning individual interpretations, in the total number of cases considered by such courts is an evidence.
