The Senate was established in constitutional law of the Czech National Council (ČNR) No. 1/1993 on 16 December 1992. The immediate reason for its creation was a need to find a place for members of the Federal Assembly, dissolved together with Czechoslovakia. Other reasons given were the positioning of the Senate as a safety device (""pojistka"") correcting laws endorsed by lower chamber and as a power balancing tool against the dominance of a single party, especially regarding constitution and electoral law.
