The JIU welcomes Marcel Jullier (Switzerland) as new Inspector

As of 2 January 2026, Inspector Marcel Jullier of Switzerland joined the Joint Inspection Unit (JIU). He brings extensive experience in financial management, audit, oversight and governance across international organizations.

A Strong Background in Oversight, Finance and Management

Inspector Jullier is a Swiss Chartered Expert in Financial and Managerial Accounting and Reporting and a Certified Internal Auditor (CIA). His professional career spans senior responsibilities in financial management, audit, human resources, procurement, information systems and programme performance monitoring.

He has held key oversight and advisory roles at the system-wide level, including as a member of the Advisory Committee on Administrative and Budgetary Questions (ACABQ) since 2017, a member of the United Nations Committee on Contributions since 2023, and a member of the Independent Oversight Advisory Committee of the International Labour Organization since 2022. These roles have provided him with in-depth exposure to governance, accountability, and reform processes across the UN system.

Inspector Jullier also brings operational experience from senior management roles within UN entities, including UN Women and UNDP in New York, where he was responsible for finance, procurement, administrative services and information systems. In addition, he has experience in strategic management in the private sector and has served as a senior adviser to the the Director of the Swiss Agency for Development and Cooperation.

Independence and Professional Integrity

A defining element of Inspector Jullier’s professional profile is his more than 20 years of service with the International Committee of the Red Cross (ICRC), including extensive field experience in conflict and post-conflict settings across multiple regions. This work required the highest standards of independence, objectivity and credibility—principles that continue to guide his approach to oversight.

As a certified internal auditor, he adheres to the core ethical principles of integrity, objectivity, confidentiality and professional competence, which are fully aligned with the values underpinning the JIU’s mandate.

Ensuring Impact through Practical and Balanced Oversight

Inspector Jullier emphasizes that effective oversight must be grounded in a thorough understanding of an organization’s mandate and operating context. He advocates for evidence-based, balanced assessments and recommendations that are clear, implementable and proportionate, with outcomes well understood and a careful balance maintained between effort and impact.

Looking Ahead

As he begins his term, Inspector Jullier identifies increasing financial constraints and ongoing organizational restructuring as major challenges facing the UN system. While efforts to streamline operations can bring efficiencies, he notes the importance of avoiding imbalances between programme delivery and oversight functions.

In this context, he sees the JIU’s role as critical in providing independent, system-wide analysis to support informed decision-making and help maintain an appropriate balance between efficiency, accountability and effective mandate implementation.

The JIU looks forward to Inspector Jullier’s contribution as it continues to promote accountability, learning and improvement across the United Nations system.
