The World Bank sanctions system has teeth. Just ask Oxford University Press, Alstom, KBR, and the more than eighty other companies and individuals debarred over the last year for violating the Bank’s Procurement Guidelines and Consultant Guidelines with corruption, fraud, or collusion. Or ask the numerous entities currently under investigation by the Bank’s Integrity Vice Presidency (INT).

If you happen to be serving as a respondent’s attorney before the Sanctions Board, this article offers some things you should know.
