ČSSD was allowed to govern alone while ODS received a number of parliamentary posts and the two parties together adopted several constitutional amendments.
[3][4] Václav Klaus's second government collapsed due to an internal crisis within ODS, the largest coalition party, related to unclear financing of the party, and the subsequent withdrawal of the Civic Democratic Alliance (ODA) and KDU-ČSL from the coalition.
Some members of ODS left the party and formed the Freedom Union, while the rest remained loyal to Klaus.
Instead, the leaders of ODS and ČSSD (Klaus and Miloš Zeman) decided to make a deal.
The new law would have almost destroyed the opposition and given the two parties nearly all the seats in the Chamber of Deputies, but it was struck down by the constitutional court, as Article 18 of the Czech Constitution explicitly states that elections to the Chamber of Deputies must be held "according to the principle of proportional representation".
