The former leader of Chad, Hissene Habre this week sought to appeal his conviction for war crimes committed during his rule in the 1980s.
Mr Habre was sentenced in Senegal in May 2016 to life imprisonment for instructing torture and mass murder during his time in office.
Claiming the composition of the jury was unfair and there were irregularities in the trial, Habre's defence team was quoted by Reuters as saying, "the decisions must be annulled and invalidated."
"I am not proud of the conditions in which the accused was tried," said Habre's lawyer Mounir Ballal.
