The article deals with the principle of proportionality, which, despite being very well-known and widely used in other European countries, has received quite a reluctant treatment in Slovakia. It was only in 2009 that the principle of proportionality was dealt with in an upto-date fashion by Constitutional Court of the Slovak Republic in two cases concerning freedom of speech.
