The former Iraqi Vice President, Taha Yassin Ramadan, was executed by hanging in Baghdad overnight. The Iraqi Tribunal had originally handed down a life sentence for Ramadan, but an appeals court ruled the sentence "too lenient".
As mentioned in previous reporting on March 16th, the Iraqi government is considering abolishing the death penalty. In purely speculative fashion, it is conceivable that some form of victor's justice is in place solely for Saddam's regime. The execution of Saddam was botched; video of his death was released (itself a war crime), some view his execution escalated the former dictator to martyrdom, and it occurred on the eve of the Islamic holy festival of Eid, which is forbidden according to Sharia Law.
The Tribunal is currently excused, as allegations regarding contempt are being contemplated against the US backed defense. It is scheduled to resume on March 26th.
Bloomberg has reporting on the former VP here.
I've reported on this on March 16th.
