In the present paper the problem of changing law into terror with reference to Polish legislation is described. The problem is being approached from the points of view of morality as well as quality of law. The author argues that absence of morality of law and poor quality of law are the basis for the development of terror. The paper also describes premises of morally wrong of law taken from L.L. Fuller's work „Morality of law” and criteria of quality of law presented by G. Radbruch in „Legal philosophy”.
