The study aims to clearly systematise and integrate the basic issues of general administrative law and select academic arguments that help clarify contemporary problems of legal regulation of public administration. The author presents key issues  in the most accessible and clear manner possible, drawing attention to their practical aspects. He also takes into account selected elements from other areas of law in order to organise the intertwined issues that make up the picture of public administration’s relationship with the law. The book has been prepared as a teaching aid for law and non-law students who need to master the complex issues of administrative law on their own.
