For centuries, Iraqi clans have used their own system to resolve disputes, with tribal dignitaries bringing together opposing sides to mediate in de facto "hearings".
If one side failed to attend such a meeting, the rival clan would fire on the absentee's home or that of fellow tribesmen, a practice known as the "degga ashairiya" or "tribal warning".
The country's Superior Magistrate Council, issued a decision last week classifying "deggas" as "terrorist acts" -- and therefore warranting the death penalty -- because of their impact on public safety.
