The OKS attempted to negotiate a joint list with the Christian Democratic Movement and Party of the Hungarian Coalition, but this failed to materialise.

Undeterred, the OKS ran alone under the banner 'Call for Slovakia' (Výzva pre Slovensko) and gained 9,422 votes, or 0.32% of the national total.

[8] The OKS supported František Mikloško of the Christian Democratic Movement (KDH) in the 2004 presidential election.

Mikloško was one of the few candidates not being former members of the Communist Party of Czechoslovakia, and ended up fifth with 6.51% share of the total vote.

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 the election, former chairman of the Czechoslovak Constitutional Court Ernest Valko and former Minister of Health Rudolf Zajac appeared on the OKS list.

Strongly defining themselves as against the left-wing nationalist coalition,[9] four MPs were elected from the list, along with ten Most–Híd members.

[15] The four OKS MPs have proposed a law restricting the government's power to build highways on privately owned land, which had earlier been ruled unconstitutional.

[16] In October 2011, the party opposed the government's commitment to the European Financial Stability Facility.

The stated aim of the OKS is to pursue the system of European conservative values such as consistency, veracity, fairness, honesty, respectability, solidarity, and observance of written and non-written treaties and agreements.
