The aim of the paper is to provide an empirical study analyzing the formal rules and subsequent political practice in the Czech Republic. As in other parliamentarian democracies, executive (government) is responsible to the lower house of the Parliament (Chamber of Deputies). According to the Czech Constitution, creation of government is a two-step process. Firstly the President of the Republic names the Head of Government-elect, who forms her government. Secondly, the whole government-elect is required to gain confidence from the Chamber of Deputies (see Art. 68 para 2 and 3 of CC) . Since the adoption of the Constitution in 1992, numerous additional interesting constitutional conventions have clarified the process. With few exceptions, the results of parliamentary elections have been quite close among the main political groups in the last 20 years. In practice this contributed to very tense negotiations and prolonged creation of governments, during which political parties often "invented" original informal solutions that usually stretched (or we can say tested) the formal rules to a great extent.
