1 By either ignoring it completely, rejecting its importance expressly due to the lack of state involvement in its making, or downplaying its importance in current international law. See respectively G. M. Danilenko, Law-Making in the International Community (1993); G. J. H. van Hoof, Rethinking the Sources of International Law (1983), at 177; C. Parry, The Sources and Evidences of International Law (1965), at 103–8.

2 The use of the term network differs greatly from that of Anne-Marie Slaughter, who explores the extent and significance of transnational and ‘transjudicial’ networks of courts and judges. See, generally, A.-M. Slaughter, A New World Order (2004).

3 Similarly to what Boer does with her ‘quasi-ethnographic’ study in the field of concept construction in cyber-warfare law, see L. Boer, ‘International Law as We Know It: Cyberwar Discourse and the Construction of Knowledge in International Legal Scholarship’, (PhD thesis, Vrije Universiteit Amsterdam 2017). We choose ‘quasi-sociological’ here as we go about our quest to better understand the profession as lawyers, and not as sociologists; echoing Orford, we were animated here by ‘juridical thinking’, in light of our legal backgrounds and our asking of questions that will interest lawyers. See A. Orford, ‘On international legal method’, (2013) 1 London Review of International Law, at 166; J. Klabbers, ‘Whatever Happened to Gramsci? Some Reflections on New Legal Realism’, (2015) 28 Leiden Journal of International Law, at 469.

4 Although the term dedoublement fonctionnel appears in Scelle’s depiction of national courts moving between their national and international ‘hats’, here it refers to Oscar Schachter’s description of the international lawyer as performing the tasks of government adviser and independent scholar. See G. Scelle, ‘Règles générales du droit de la paix’, (1933) Recueil des cours 358, at 46, versus O. Schachter, ‘The Invisible College of International Lawyers’, (1977) 72 Northwestern University Law Review, at 218.

6 On networks of actors in specific areas of the profession using professional rosters as a source see S. Puig, ‘Social Capital in the Arbitration Market’, (2014) 25 European Journal of International Law at 387; M. Langford, D. Behn and R. Lie, ‘The Revolving Door in International Investment Arbitration’, (2017) 20 Journal of International Economic Law, at 301. On scholarship and citations see S. T.

Boer, ‘“The Greater Part of Jurisconsults”: On Consensus Claims and Their Footnotes in Legal Scholarship’, (2016) 8 Leiden Journal of International Law, at 1021. On the profession’s ‘professionals’ see M. Koskenniemi, The Gentle Civilizer of Nations: The Rise and Fall of International Law, 1870-1960 (2002); L.

29 Some authors do not mention ‘teachings’ or the ‘invisible college’ at all – see Danilenko, supra note 1; V. D. Degan, Sources of International Law (1997). Others deny the role of ‘teachings’ expressly due to the absence of state involvement in their making, see van Hoof, supra note 1, at 176–7. Another section of the literature dismisses their importance as merely ‘grammarians’, and not influential figures in the actual content of legal norms, exemplified by H. Thirlway, The Sources of International Law (2014), at 126–7. See this view perpetuated, for instance, in the unease with which the International Law Commission addresses ‘teachings of publicists’ in its current work on the identification of customary international law in ILC, ‘Report of the International Law Commission on the work of its Sixty-eight session’ (2 May–10 June and 4 July–12 August 2016) UN Doc. A/71/10. Empirical work on the use of scholarship in international adjudication appears sometimes to hold a more balanced judgment: see O.

56 Both Morgenstern and Bastid were eminent jurists and some of the earliest and most accomplished women international lawyers of their generation; for anyone dedicated to the study of diversity in the international legal profession their names stand to reason. Morgenstern wrote one of the earliest books on international organisations law (Legal Problems of International Organisations, 1986), was a member of the BYIL’s editorial board, and wrote the ILO portion of Sir Clarence Wilfred Jenks’ obituary, but her own obituary was not featured in the publication. Bastid was the daughter of Jules Basdevant, member of the Advisory Committee of Jurists drafting the ICJ Statute, PCIJ and ICJ judge. She was also the first woman to act as a Judge at the International Court of Justice as judge ad hoc for Tunisia in Application for Revision and Interpretation of the Judgment of 24 February 1982 in the Case Concerning the Continental Shelf (Tunisia/Libyan Arab Jamahiriya) (Tunisia v. Libyan Arab Jamahiriya). The upcoming book edited by Immi Tallgren – Portraits of Women in International Law: New Names and Forgotten Faces? – will do important work on mapping out women’s participation and its politics.

73 It would have been possible to use distinct columns for every profession, as well as Boolean variables (the possible values amounting to either ‘true’ or ‘false’) to log the various affiliations and professional characteristics. However, the comparatively scarce diversity of the international legal profession represents a finding of this study, rather than a premise. Moreover, reliance on the advanced filtering capabilities of NodeXL made one such exercise rather pointless.

74 The column names could have been different and more expressive, but are just a consequence of the requirements for data import within the software Gephi.

79 Simply put, the use of the Excel filtering features greatly streamlined the filtering process of nodes having more than one attribute. As this choice worked well in practice, it has not been necessary to use more sophisticated techniques, such as using Boolean data type (true or false) for each and every potential attribute.

84 They also show the ubiquity of informal networks, revealing the highways along which ideas travel within this community of lawyers. Although it is beyond the scope of this article to make causal claims of how ideas travel within the community, sociological works referred to above show how the connections between professionals can illuminate certain patterns. Saying networks suggest pathways for the movement of ideas is not to say that they necessarily promote their substantial homogeneity. One need only to think that one of the thickest edges and strongest connections is between Lord Arnold McNair and Sir Hersch Lauterpacht, both of whom worked on the Law of Treaties though espousing diametrically opposing views on certain issues, or that Sir Derek Bowett and Sir Ian Brownlie had parallel professional lives and were deeply connected but reached opposite conclusions on the use of force. Concepts and personal positions may be influenced by strengthening opposition as well as convergence. This is why quantitative work such as ours must be read as supplementing other mapping efforts that employ more traditional sources, such as professional rosters, and citation analysis, as well as qualitative studies that look at the content of certain professional contributions, such as critical histories of the profession and of formal and informal international institutions.
