The UN Guiding Principles on Business and Human Rights (GPs) expect businesses to participate in operational-level, non-judicial mechanisms to address the grievances of communities affected by their activities. While there is guidance on operational-level grievance mechanisms as to what constitutes an effective process, inquiries into the effectiveness of outcomes have been met with less success. This article identifies three key incongruities within the GPs regarding effective outcomes: (1) the broader interpretation of remedy within the Remedy Pillar compared to the Respect Pillar; (2) the novelty of enforcing human rights through dialogue and engagement as opposed to adjudication; and (3) the difficulty in reconciling objective human rights standards with the subjective preferences of the parties. It then aims to resolve these issues by applying a human rights-based approach: examining how empowerment of communities can act as the founding basis for understanding whether an outcome is effective. It concludes by examining the working of the Porgera Mine mechanism from this perspective.

This article considers the emerging practice of human rights impact assessment (HRIA) in the field of business and human rights. As HRIA is relatively new, current approaches vary considerably, indicating that there is a need for the business and human rights community to engage in further dialogue and debate about what good practice HRIA can and should entail. I propose five key criteria for HRIA of business activities: (1) applying international human rights standards; (2) considering the full scope of impacts; (3) adopting a human rights-based process; (4) ensuring accountability; and (5) addressing impacts according to severity. It is suggested that these criteria should form the basis of methodologies used to assess human rights impacts of business activities, with the view to developing HRIA practice that meaningfully contributes to preventing and addressing adverse impacts of business activities on the human rights enjoyment of workers and communities.
