On Thursday, the Central Election Committee officially confirmed the results of Sunday's parliamentary vote, in which pro-presidential Ak Zhol won a landslide victory of 46.9%.
Despite coming second in the vote, Ata Meken has been denied seats in the legislature by a rule stating that parties must gain at least 0.5% of votes in each of the Central Asian country's six regions and two largest cities. The party failed to reach the threshold in Kyrgyzstan's second city Osh, by just a few dozen votes.
Two other parties - the moderate Social Democratic Party and the Communist Party - narrowly overcame the 5% threshold to enter parliament, and will receive 11 and eight seats, respectively.
President Kurmanbek Bakiyev's party will have 71 seats in the 90-seat legislature.
Ata Meken's headquarters said the party, along with several other opposition parties that failed to gain seats in parliament, had copies of the vote count from polling stations that prove that they overcame the 0.5% regional barrier.
The opposition, which accused officials of rigging the vote, said it would hold large-scale protests on Friday if the Central Election Commission "ignores the voice of the electorate."
On Tuesday, the Kyrgyz Supreme Court ruled to alter the 0.5% threshold for regions following a suit filed by the president's party, in a bid to avoid the emergence of a one-party state. Before the ruling, parties were required to gain 0.5% of the national vote in each region. The amendment meant that parties only had to gain 0.5% of votes from each regional electorate, but even under the modified rule, Aka Meken failed to overcome the threshold.
Russian President Vladimir Putin has congratulated Bakiyev on the "successful conduct of parliamentary elections."
However, monitors from the Organization for Security and Cooperation in Europe criticized the lack of transparency in the vote-counting procedures.
The ex-Soviet state's parliament will convene for its first session on December 21.
