[1][2] On 7 October 2014, Kvarchia was elected with 27 to 4 votes (out of 31 present) as chairman of the Committee for Agrarian Policy, Natural Resources and Ecology, replacing Nodik Kvitsinia, who was under investigation, and would later be convicted, for the murder of Russian businessman Sergei Klemantovich and his partner Oksana Skarednova.
The investigation revealed that the bomb had detonated early, killing the would-be assassin, identified as a Russian citizen named SL Tarasenko, and that Kvarchia had been his intended target.
On 2 November, police detained Adgur Korsentia, a member of the political council of opposition party Amtsakhara, on suspicion of involvement in the attempted attack.

[8] Kvarchia later announced his candidacy for the 2025 Abkhazian presidential election but ultimately withdrew in favour of Adgur Ardzinba, citing health reasons.
