At para. 45, the Appeals Chamber found that the contribution to historical record “intrinsically falls within the value given to a guilty plea”:

45. With regard to the Appellant’s claim that the Trial Chamber failed to consider that he contributed to a “historical record”,[1] the Appeals Chamber notes that this factor, although not expressly mentioned by the Trial Chamber, intrinsically falls within the value given to a guilty plea. Indeed, such a contribution to help establish the truth is one of several reasons which have been given in the jurisprudence of the International Tribunal and the ICTR for the mitigating effect of a guilty plea.[2] As such, this factor is part of the substantial weight the Trial Chamber has attached to the Appellant’s guilty plea.[3]
