Sentencing judges should prepare two versions of sentencing remarks where a discount is sought for cooperation with authorities — one restricted version fully explaining the cooperation and one public version. Oblique or veiled references to cooperation in sentencing remarks are inappropriate as they do not provide meaningful explanation of how cooperation informed the sentencing discretion. The 'highest level' of cooperation warranting discounts of up to 66 per cent is reserved for true informers, such as members of organised crime syndicates who inform against other members at grave personal risk; cooperation assessed as 'significant' in a letter of assistance does not reach this level.
