Details of the defence team’s submission to judges were released on Friday.
The defence called it “vindictive” and said it places too much of the blame to the former Liberian president for crimes committed during Sierra Leone’s civil war.
Taylor was convicted for crimes against humanity in a trial that lasted six years. He was also convicted of war crimes, murder and terrorism.
He is due to be sentenced on May 30.
The defence said judges should not support “attempts by the prosecution to provide the Sierra Leoneans with this external bogey man upon whom can be heaped the collective guilt of a nation for its predominantly self-inflicted wounds.”
