Kelly v UCD [2025] IESC 6: clarifying the boundaries on judicial bias disqualification

The Irish Supreme Court’s decision in Kelly v UCD1 is a significant ruling on judicial bias and disqualification. It is the first case to consider the implications of familial connections between judges and law firms representing parties since the Judicial Conduct Committee published its Guidelines on Judicial Conduct and Ethics in 2022.2 The case clarifies the legal test for objective bias, delineates its boundaries, and addresses the role of judicial conduct guidelines in disqualification decisions. It also has broader implications for other common law jurisdictions, particularly England & Wales, where similar issues of judicial propriety and public confidence in impartial adjudication arise.
