The commission made a similar decision with regard to another lawmaker, Muratbek Malabaev.
Commission Chairman Tuigunaly Abdyraimov told RFE/RL's Kyrgyz Service the decision was made to conform to the Kyrgyz Constitution.
"Aidar Akaev and Muratbek Malabaev have been absent from Kyrgyzstan for the entire past year," Abdyraimov said. "Last year they did not participate in any session of the Jogorku Kenesh [parliament]. It is written in the constitution that if a deputy leaves the country, or does not regularly attend parliamentary sessions, then his or her mandate should be terminated. We acted in accordance with Kyrgyzstan's fundamental law."
Both Malabaev and Aidar Akaev won parliamentary seats in the disputed 2005 elections that led to President Akaev's ousting and escape to Russia with his family.
Kyrgyz officials say Malabaev, who is reportedly close to the Akaev family, currently lives in Moscow.
On October 4, Deputy Prosecutor-General Aleksandr Neforosnykh said two criminal cases had been opened against Aidar Akaev, but none against his father.
Critics say President Akaev and his entourage enjoyed control over an extensive part of Kyrgyzstan's economy.
