This article reviews and assesses the language, human rights content and compliance mechanisms of the voluntary policies and/or codes developed by a number of corporations, industry groups, intergovernmental organizations and multistakeholder initiatives, as well as associated corporate practices. The analysis shows that these voluntary regimes are flawed and inadequate, and therefore unable to ensure that TNCs are not complicit in human rights violations in their extra-territorial activities... This paper will review and assess the voluntary self-regulatory instruments and practices of Talisman Energy, Premier Oil, BP and Shell.
