The appeal lodged by the accused or the prosecution may state that it does not contest the answers given by the assize court on guilt and that it is limited to the decision on sentence.
In this case, only witnesses and experts whose testimony is necessary to enlighten the assessors and jurors about the facts committed and the personality of the accused shall be heard before the assize court ruling on appeal, without hearing persons whose testimony would be useful only to establish his guilt.
When the assize court retires to deliberate, the provisions relating to questions on guilt shall not apply.
