The Contributions of the Role of Independent Directors to the Corporate Governance Regimes of the United Kingdom and the United State

Abstract

Independent directors have become a central pillar of corporate governance reforms in both the United Kingdom and the United States, intended to mitigate agency problems, strengthen board oversight, and enhance accountability. Regulatory frameworks such as the UK Corporate Governance Code 2024 and the Sarbanes-Oxley Act of 2002 reflect a shared belief that board independence is essential for effective corporate monitoring. However, this paper critically evaluates whether independent directors have, in practice, made a useful contribution to corporate governance outcomes in either jurisdiction.

Drawing on a comparative doctrinal analysis and detailed case studies, the paper demonstrates that formal independence has not consistently translated into effective oversight. Post-reform corporate failures, including Carillion and Patisserie Valerie in the UK, and Wells Fargo and Boeing in the US, occurred under fully compliant governance regimes dominated by independent directors. These cases reveal a persistent gap between regulatory design and practical performance. Independent directors were frequently constrained by reliance on management-controlled information, limited industry-specific expertise, structural and social bias, and appointment processes influenced by executives.

The paper argues that independence in form does not guarantee independence in substance. While empirical evidence shows that independent directors can contribute positively where they are genuinely engaged, informed, and competent, their effectiveness is undermined by structural weaknesses embedded within current governance frameworks. It is therefore argued that the continued regulatory emphasis on formal independence is insufficient. Meaningful reform requires a shift from formal independence criteria towards functional independence, emphasising access to information, relevant expertise, and genuine capacity to challenge executive power. Without such reforms, independent directors risk remaining symbolically central but practically ineffective within modern corporate governance regimes.
