How the law is passed in Mongolia?

Following picture was taken by a TV cameraman at the parliament session hall that was discussing whether to accept the President Ts.Elbegdorj's veto. The narrator says it is an ordinary scene that how the law is passed in Mongolia at the Parliament session hall by pressing another person's "Yes" button when balloting. Look for current Prime Minister S.Batbold (MPRP), President of Bank of Mongolia L.Purevdorj (MPRP), Minister of Health D.Lambaa (DP), and former Minister of Justice and Home Affairs Ts.Munkh-Ochir (MPRP). The Parliament "majority" rejected to accept the President Elbegdorj's veto.
