With great sadness, the International Investment Law Centre Cologne
(IILCC) bids farewell to Karl-Heinz Böckstiegel, who passed away on 19
December 2025. Professor Böckstiegel was one of the defining figures
of international investment law and one of the world’s leading figures
in international arbitration. His doctoral dissertation of 1962,
addressing the general principles of international law on the taking
of property (Die allgemeinen Grundsätze des Völkerrechts über
Eigentumsentziehung), set enduring benchmarks for the treatment of
expropriation in international law. With his habilitation thesis of
1971 on the State as a contractual partner of foreign private
enterprises (Der Staat als Vertragspartner ausländischer
Privatunternehmen), he produced a foundational work that has had a
lasting impact on the doctrinal underpinnings of modern investment
contracts. From 1984 to 1988, he also served as President of the
Iran-United States Claims Tribunal in The Hague, shaping its
jurisprudence during a period of decisive importance for international
economic law. Professor Böckstiegel was closely associated with the
IILCC. As Honorary Chairman, he accompanied, supported, and
substantively shaped the Centre’s work over many years. We owe
Professor Dr. Karl-Heinz Böckstiegel a deep debt of gratitude and will
preserve his memory with great respect.
