OKS offered to run on the common candidate list with the Christian Democratic Movement in the 2006 parliamentary election. This offer was turned down by the KDH, the Civic Conservatives had to raise 500,000 korún as a fee for the party to participate. In March 2006, OKS member Ondrej Dostál applied to the Constitutional Court, considering the possible unconstitutionality of the election participation fee, saying the fee affects his right to run for office. In the election, former Chairman of the Czechoslovak Constitutional Court Ernest Valko and former Minister of Health Rudolf Zajac appeared on the OKS list. The party obtained 6,262 votes which represented 0.27% share of the total vote.
