From a historical and general point of view, ethics are a concept that mainly designates a custom, manner, or a tradition. Ethics have a lot in common with morality as a system of generally accepted customs and manners. Ethics and morality mingle to a certain extent since the judge’s authority in criminal proceedings is directly proportional to public trust in the judge’s moral qualities. Ethical behaviour means respecting generally accepted customs, manners or traditions. We, on the other hand, speak of a special kind of ethics – the so-called professional ethics or professional ethical behaviour delimited by the strict framework of Czech criminal proceedings.
