The history of international environmental law as an academic topic is generally associated with the emergence of treaties and case law on specific sectors such as shared watercourses, the oceans, or – from 1900 onwards – selected wildlife species. Doctrinal attempts at identifying common (trans-sectoral) elements, and a coherent discipline of international regulation and governance in this field, did not make their appearance until well into the second half of the 20th century, with a prevailing and near-exclusive focus on public international law.
One notable exception was the pioneering work of Karl Alexander Neumeyer (1869-1941), who approached the subject from his distinct perspective of conflict of laws, in a monumental four-volume treatise titled Internationales Verwaltungsrecht (International Administrative Law, 1910-1936).[1] His life-time vision was the development of a new unified system of rules applicable to the transnational aspects of administrative law, to match the well-established conflict rules of private international law and procedure. And in the process, as part of an effort to demonstrate the pragmatic foundations of his approach in different sectors of public administration, he also assembled and analyzed a unique compendium of contemporary legal source materials that would indeed qualify today as typical ‘transnational environmental law’.
Chapter 8 in volume 2 of Neumeyer’s treatise (pp. 1-135), published in 1922, was headed Naturkräfte und Naturerzeugnisse (forces and products of nature). The first section, dealing with internationally shared water resources and water power, is based on the author’s earlier study of “water uses in international administrative law” (1915),[2] criticizing the rigid territorial sovereignty principle invoked by the Austrian Administrative High Court in the notorious 1913 Leitha River case,[3] and advocating the reciprocal protection of foreign legal interests along the lines of the 1909 US-Canadian Boundary Waters Treaty.[4] Other sections deal with the transboundary regulation of mineral resources; agriculture, forestry, hunting and fishing (based in part on the author’s early practical experience as law clerk at a district court in the Bavarian-Austrian border region); and the management and conservation of marine living resources, including a discussion of the 1893 Bering Sea fur seals arbitration.[5] Karl Neumeyer’s emphasis on the need for a mutual ‘other-regarding’ accommodation of foreign concerns, across the entire spectrum of nature-related topics, was way ahead of his times.
Neumeyer taught international law – with a focus on history and conflict of laws – at the University of Munich from 1901 onwards, until the Nazi regime forced him into retirement in 1934 because of his Jewish ancestry and barred him from continuing to work with the Hague Academy of International Law (where he had first lectured in 1923) and the Institut de Droit International (which had elected him to full membership in 1926).[6] Ultimately, when he was notified of the impending eviction from his house and the confiscation of his library, he and his wife decided to commit suicide on 16 July 1941.[7] There is a memorial tablet at their former home near the university; a Neumeyer-Strasse in the city; and in 2008, the Munich Law Faculty (whose dean he was in 1931-32) named the building that houses its Institute of International Law (which he had helped to create) in Karl Neumeyer’s honor and memory.
