Today's early testimony in the trial of Saddam Hussein and former members of his regime turned into shouts and bickering.
The dispute started after the chief judge told a defense witness not to refer to Saddam as "Mr. President."
The defense team contends the court is illegitimate because it was created under the American military presence.
But the chief judge calls this a purely criminal case that has nothing to do with politics.
Only three lower-level defendants were present when the first defense witness took the stand, testifying from behind a curtain to protect his identity.
Saddam and co-defendants are charged in a deadly crackdown on Shiites in the 1980's.
