The Algorithmic Fiduciary: A Comparative Analysis of Board Oversight, AI Liability, and the Business Judgment Rule in the EU and US

Abstract

The rapid integration of Artificial Intelligence (AI) into corporate decision-making processes presents a foundational challenge to traditional corporate governance models. As algorithms increasingly displace human discretion in strategic resource allocation, risk management, and hiring, the classic definitions of fiduciary duties—specifically the Duty of Care and the Duty of Loyalty—are being strained. This article provides a comparative legal analysis of how two dominant jurisdictions are adapting to this shift: the European Union, with its precautionary, statute-based EU AI Act, and the United States (specifically Delaware), which relies on the adaptable, judge-made Business Judgment Rule.

The article argues that a dangerous "accountability vacuum" is emerging. In the US, the deference shown to directors risks shielding "algorithmic negligence" from liability, while in the EU, the rigid categorization of "High-Risk AI" may stifle corporate innovation without necessarily enhancing board competence. Through a Rule of Law lens, this paper examines the tension between "Algorithmic Opacity" (Black Box problems) and the legal requirement for "Reasoned Decision Making," ultimately proposing a new standard of "Technological Competence" for corporate directors globally.
