Zoltán Magyary was an internationally recognised Hungarian professor of law who carried out research in modern theories of administration and state theories. Defending the values of the rule of law and taking action against the anomalies of legal formalism were among his major scientific goals. According to him, one of the most important functions of a legal system is the protection of human rights, therefore he accepted the view that courts must have the authority to review administrative decisions. At the same time, he stated that the effective and productive functioning of administrative institutions and the executive power is a priority in a legal system. Due to the fact that he did not provide a complete analysis of the correlation between the rule of law and the effective functioning of administrative institutions, he opened the possibility for posterity to give various and different interpretations of the issue.
