A bill of the 23rd March 2006, worked out in the Department of Justice, intends an introduction of the crime of hooliganism character to the penal code. What is it “crime of hooliganism character”? What circumstances show that it was committed a crime of hooliganism character? It should be emphasized that an institution of the act of hooliganism character isn’t new in the Polish research of the penal law. It was known to the Polish code of 1969 and currently can be found in the misdemeanor (administrative offence, delinquency) law. Since the beginning of being she gave rise to a great deal of discussion and was criticized. The revised bill includes a definition of this institution. But an analysis of the judicature and researches of the literature show, how ambiguous phenomenon is the hooliganism and how unclear are the elements of the definition of the institution of the crime of hooliganism character, which is written down in this bill. So it should be considered, if a proposed amendment to the penal code is legitimate (well-founded). It should be also considered, if an amendment to the Polish penal law is necessary. A justification of the bill raises in this scope a lot of doubts and doesn’t persuade of the rightness of the proposed amendments in the penal law.
