Lawyers acting for Saddam Hussein on Sunday submitted appeals against the sentences imposed on the ousted leader and his co-defendants in the Dujail trial, a top Iraqi official said.
The lawyers submitted appeals on behalf of all seven defendants, including death sentences against Saddam and two other aides, the official said.
"They submitted the appeals to the appeal chamber today," the official, who did not wish to be named, said.
A panel of Iraqi appeal court judges is already looking into the case and now "obviously has to look into these documents given by the defence lawyers," he added.
On November 5, Saddam was sentenced to death by hanging for ordering the execution of 148 Shiites from the village of Dujail after he escaped an assassination bid there in 1982.
His half-brother and intelligence chief Barzan al-Trikrit was also sentenced to death, along with Awad Ahmed Al-Bandar, chairman of the so-called Revolutionary Court which oversaw the Shiites' executions.
Saddam's former vice president Taha Yassin Ramadan received a life sentence, while three Baath party officials from Dujail received 15 years each and a fourth, more junior figure, was cleared.
Those condemned to death or life in jail have an automatic right of appeal according to Iraq law.
Saddam and six other former regime officials are currently also on trial in a separate genocide case involving the massacre of 182,000 Kurds in northern Iraq in 1988.
