19 As a legal matter, most national jurisdictions prohibit complicity in the commission of a crime, and a number allow for criminal liability of business enterprises in such cases. Typically, civil actions can also be based on an enterprise’s alleged contribution to a harm,  although these may not be framed in human rights terms. The weight of international criminal law jurisprudence indicates that the relevant standard for aiding and abetting is knowingly providing practical assistance or encouragement that has a substantial effect on the commission of a crime. Conducting appropriate human rights due diligence should help business enterprises address the risk of legal claims against them by showing that they took every reasonable step to avoid involvement with an alleged human rights abuse. However, business enterprises conducting such due diligence should not assume that, by itself, this will automatically and fully absolve them from liability for causing or contributing to human rights abuses. 18. In order to gauge human rights risks, business enterprises should identify and assess any actual or potential adverse human rights impacts with which they may be involved either through their own activities or as a result of their business relationships. This process should: (a)  Draw on internal and/or independent external human rights expertise; (b) Involve meaningful consultation with potentially affected groups and other relevant stakeholders, as appropriate to the size of the business enterprise and the nature and context of the operation. Commentary The initial step in conducting human rights due diligence is to identify and assess the nature of the actual and potential adverse human rights impacts with which a business enterprise may be involved. The purpose is to understand the specific impacts on specific people, given a specific context of operations. Typically this includes assessing the human rights context prior to a proposed business activity, where possible; identifying who may be affected; cataloguing the relevant human rights standards and issues; and projecting how the proposed activity and associated business relationships could have adverse human rights impacts on those identified.
