Justice Andrew Collins dealt a blow to campaigners from Military Families Against the War in late December.
He told the families they could not seek a judicial review into the government’s refusal to allow a public inquiry into the Iraq war.
Rose Gentle, from Military Families Against the War, said, “The families believe the decision to invade Iraq was based on deceit and lies. Our sons and husbands were sent to their deaths on the backs of these lies.
“This war is a crime against humanity and it demands a full independent and effective public inquiry into the background and build up to the invasion of Iraq. The families are determined to continue with their campaign.”
