It did so after receiving notification from the Interior Ministry that the individuals in question were disqualified from election to the Saeima under the country's election law. The eight candidates were Aivars Zablockis and Nikolajs Žeļezņakovs, Zigfrīds Laicāns and Valdis Taupmanis, Edgars Krūmiņš, Katrīna Brandala, Aivars Silinieks and Tatjana Ždanoka. Ždanoka has been barred in the past as Latvian courts have found that she was a member of the Communist Party of Latvia after 31 January 1991, making her ineligible. The Election Commission additionally sought information from the Security Police and the Constitution Protection Bureau to confirm her ineligibility.
