Before seeking the sentence, the Prosecutor General’s Office at the N’Djamena Appeals Court first read out the charges against Ladé.
It pointed out that the accused was not eligible for a presidential amnesty declared in June by President Idriss Déby, despite a plea to that effect by his lawyers.
Ladé was repatriated to Chad shortly after his arrest in 2015 in the Central African Republic.
He is accused of, among other things, rape, murder, criminal association, a role in an insurrection, murder and statutory rape.
The verdict is expected later on Thursday.
