The thesis will deal with the mechanism of constitutional referrals, i. e. the procedure by which an ordinary court may lodge a submission to a constitutional court in order to clarify the constitutionality of a law that the ordinary court shall apply in a particular case. The first part will address this mechanism from a general perspective – it will delineate the main features and functions and describe the framing of the constitutional referrals procedure as a platform for judicial dialogue on constitutional issues. Building up on that, the second part will present an empirical study of constitutional referrals in Czechia. The case study will answer the question of whether this kind of concrete judicial review serves in Czechia as a space for rational dialogue on constitutional issues or it is rather only a series of utterances of two actors who do not listen to each other.
