In a decision sought by the United States government, the Secretary General of the United Nations has been found immune from lawsuits over employment discrimination.
Recent case: Mathieu worked successfully for the United Nations in New York for several years on a year-to-year contract. Then he began clashing with a supervisor and received his first negative review. Shortly after, his yearly contract was not renewed.
Mathieu appealed the decision internally. When the UN refused to reverse its decision, he filed a lawsuit in federal court against the UN and the Secretary General, alleging whistleblowing and retaliation under Title VII.
The U.S. Attorneys Office entered the fray, arguing that the case should be dismissed because the UN and its diplomats have absolute immunity against lawsuits. The court agreed and tossed out the case. (Koumoin v. Ki-Moon, No. 16-CV-2111, SD NY 2016)
