Attribution and due diligence
The 2001 ILC Articles on State Responsibility include eight Articles on attribution, but are virtually silent on due diligence. The latter principle applies in relation to private persons, the conduct of which ‘is not as such’ attributable to the state, according to the ILC.60 In underpinning its opinion the Commission cites the 1923 Tellini case:
The responsibility of a State is only involved by the commission in its territory of a political crime against the persons of foreigners if the State has neglected to take all reasonable measures for the prevention of the crime and the pursuit, arrest and bringing to justice of the criminal61
In its comments to the Articles on attribution, the ILC states that
[i]n theory, the conduct of all human beings, corporations or collectivities linked to the State by nationality, habitual residence or incorporation might be attributed to the State, whether or not they have any connection to the Government. In international law, such an approach is avoided, both with a view to limiting responsibility to conduct which engages the State as an organization, and also so as to recognize

the autonomy of persons acting on their own account and not at the instigation of a public authority. Thus, the general rule is that the only conduct attributed to the State at the international level is that of its organs of government, or of others who have acted under the direction, instigation or control of those organs, i.e. as agents of the State.   
The combined application of the principles of attribution and due diligence rules out the responsibility of states for acts of TCOs, other than those they direct, or fail to pursue and prosecute. But even if that intent or unwillingness could be established, it would only provide other states with the right to make a claim under the law of international state responsibility, or file individual indictments with the ICC.63
