"A fair trial in this case is absolutely imperative for historical truth," stated Clark in this Reuters report. "It is absolutely essential that the court is legal in its constitution. A court cannot be a court unless it is absolutely independent of all external pressures and forces."
Hussein's trial is scheduled to resume on Monday after a 40-day adjournment, granted by the court to allow both sides to prepare their cases.
The 77-year-old Clark will join former justice minister of Qatar, Najeeb al-Nauim in defending Hussein.
Hussein and his co-defendants are being tried for their alleged involvement in the deaths of 148 Iraqis after a failed assassination attempt on Saddam in 1982.
Do Clark and al-Nauim face an impossible task in defending Hussein? Remember, Saddam has faced may trials.
