Abstract

Frieder Roessler devoted his professional career to international law and inter-governmental cooperation in international trade. He believed in cooperation, economic integration, and the international rule of law, as objectives for the promotion of world peace, justice, and prosperity. In the GATT Secretariat, he contributed importantly to improving the legal quality of GATT dispute settlement decisions and to strengthening the rule of law in the multilateral trading system. After 1995, he focused on international trade law being upheld towards and by developing countries. Frieder Roessler was an international civil servant who defended the highest standards of independence, impartiality, and integrity. His legacy is a deep understanding of GATT and WTO law, which he disseminated through his scholarship, and the quality and rigour of his lawyering. Frieder Roessler was a kind, approachable, warm person, committed, passionate, and faithful to his convictions. He generously shared his wisdom as interlocutor in stimulating legal discussions. All international trade lawyers can continue to learn enormously from him and his experiences.

1 Frieder’s surname was in fact Rössler, but he may have chosen a transliterated spelling without German Umlaut early in his international career, notably all publications appeared under the surname Roessler. Consistency with Frieder’s scholarship will prevail here over legal correctness.

2 See the other accounts in this volume, notably by Ernst-Ulrich Petersmann, Werner Zdouc, and Petros Mavroidis.

3 One story is Frieder’s question about a legal affairs office that generated laughter in a GATT Secretariat staff assembly and a senior colleague telling him: ‘here at the GATT, we do not believe in law, we believe in pragmatism’. The other version is that lawyers were considered useful for the liability for a broken photocopier, but not for settling trade disputes.

4 Frieder considered his transfer to the newly created Office of Legal Affairs of the GATT Secretariat as the moment at which his ‘real career at the GATT had begun’; F. Roessler, Interview recorded on 28 June 2012, www.wto.org/video/2012_06_28_lad_roessler.mp4.

5 Frieder pointed out that the European Economic Community, in existence from 1958, had not been able to defend its interests when the GATT was drafted and that it had no pre-1948 legislation that could benefit from the ‘grandfathering clause’ of Paragraph 1(b) of the Protocol of Provisional Application. It also did not benefit from a waiver such as that granted to the United States in 1955. Roessler, ‘The Role of Law in International Trade Relations’, supra n. 3, 164.

6 This divergence was well described by Åke Lindén at the June 2012 conference on the 30th anniversary of the Legal Affairs Division (www.wto.org/english/tratop_e/dispu_e/lad30bday_e.htm). See also Å. Lindén (2015) ‘The First Years of the GATT Legal Service’, in G. Marceau (ed.), A History of Law and Lawyers in the GATT/WTO. WTO/Cambridge University Press, 135, 137–138. https://www-cambridge-org.demo.remotlog.com/core/books/history-of-law-and-lawyers-in-the-gattwto/AE5C13F457221B489FCEB709D8564BE8.

7 Then ensued a controversy over who should head the new Office of Legal Affairs. The United States proposed university professors and trade law experts (American or French), whereas the European Economic Community first favoured a non-lawyer and insisted (successfully) on a practitioner from within the GATT Secretariat. See Lindén, supra n. 6.

8 This was significantly motivated by an interest in containing unilateralism of the United States under section 301 of the Trade Act of 1974, an interest shared also by others, notably Japan.

12 And that thorough legal analysis amounts to gap-filling. But see Paul Luyten, supra n. 11.

14 It did not deliver the quality and consistency which the GATT contracting parties wanted. The 1981 GATT panel report in SpainSoyabean Oil (L/5142, 17 June 1981, unadopted) is widely cited as a qualitative low point which definitively confirmed the need to improve the legal quality. See Roessler, supra n. 5, 165, Porges, supra n. 9, 225–226.

15 This was what disputing parties wanted to know, whereas the prior approach gave priority to finding a solution which both parties could accept, as they had indicated during the process.

16 Amelia Porges makes this important point. Supra n. 9, 226 and 227.
