The World Bank Inspection Panel celebrates its 30th anniversary this year. Established in 1993, the Panel is an independent mechanism for addressing complaints from individuals and communities who believe that they have been, or are likely to be, adversely affected by a World Bank-funded project. The Panel's work has contributed to improved accountability and transparency of the World Bank and its projects, and has played a key role in ensuring that the Bank's development activities are carried out in a socially and environmentally responsible manner. During the course of 2023, we will be organizing a series of activities to mark the Panel's 30th anniversary, including a public event at the American University in Washington, DC on April 6th, and programs at the Spring and Annual meetings of the World Bank. We welcome all to reflect on the progress that has been made in strengthening accountability over the past three decades, and to look forward to how the Panel can continue to contribute to development effectiveness in the context of the World Bank operations in the years to come.
