Chattels – Dinar Guru For a parliament session to obtain a quorum, half plus one of its members must show up to vote — which is 168 members. Half plus one of the attendees must vote for the Cabinet to approve it. This means Shiite parties can hold the parliament session or make quorum without the Sunni and Kurds, but today there were Shia defectors also and even if the Shia can muster quorum and decision without the support of Sunni and Kurdish parties will add to an already divisive situation in Iraq , in my view.
