This article show that �the justice and peace law� approved by the Colombian Congress, encourage the impunity because improperly opens the door to the possibility that some perpetrators may individually receive generous judicial benefits without requiring corresponding assurances from them; thus allows members of illegal armed groups to benefit from amnesties or pardons.
