Bruno Simma (born 29 March 1941 in Quierschied, Germany) is a German jurist who served as a judge on the International Court of Justice (ICJ), from 2003 until 2012.
He served as an affiliated overseas faculty member of the University of Michigan Law School, teaching classes in Ann Arbor until 2021, and as one of the three third-country arbitrators on the Iran–United States Claims Tribunal, to which he was appointed in 2013.
[3][4] Simma has acted as an arbitrator in numerous inter-state, foreign investment, international commercial, and sports law cases.
[1] Among them, he served on the NAFTA Chapter 11 investor-state dispute panel in the Clayton/Bilcon case, in which a U.S. investor sought damages under NAFTA Chapter 11 after Canada and Nova Scotia rejected the investor's project to mine basalt and build a marine terminal on the Digby peninsula in Nova Scotia based on an environmental impact assessment conducted under federal and provincial law.
The dissenting panel member warned that in key respects "the decision of the majority will be seen as a remarkable step backwards in environmental protection."
