Professor Parella previews her new paper, “Protecting Contract’s Hidden Parties,” in which she argues that harm to third parties from supply chains offers a compelling reason for requiring human rights due diligence in supply chains. Many scholars have turned to fiduciary duties or negligence theories to create incentives for companies to consider non-shareholder interests. This article shares this objective but takes a different path by examining a corporation’s duties to others in its role as a contracting party. This analysis can help to address human rights violations in supply chains and may also have implications for third-party harms arising in other types of contracts.
