Act on Illegality of the Communist Regime and on Resistance Against It (Czech: Zákon o protiprávnosti komunistického režimu a o odporu proti němu, zákon č.
is an act passed on 9 July 1993 in the Parliament of the Czech Republic.
This act declared the Communist regime in Czechoslovakia (25 February 1948 – 23 April 1990) as illegal and the Communist Party of Czechoslovakia as a criminal organisation.
[1] The resolution made the Czech Republic the first former Eastern Bloc country or successor state to officially condemn a former Communist regime.
[2] According to the Constitutional Court although the Act is more a political declaration than ordinary act regulating rights and duties, it is necessary to cope with the regime and it can be made in the form of statute if the Parliament wishes so.
