RT Article T1 Comparing WTO panelists and ICSID arbitrators JF Oñati Socio-Legal Series VO 1 IS 4 SP 1 OP 25 A1 Costa, José Augusto Fontoura 1968- LA English YR 2011 UL https://krimdok.uni-tuebingen.de/Record/1689292822 AB Who are people who make the decisions in trade and investment dispute settlement systems? In order to describe and analyze investment arbitrators and trade panelists, the whole populations of people nominated to ICSID’s tribunals and committees as well as to WTO Panels from 1995 to 2009 were studied, considering their specialization in law, and their career backgrounds as public servants, academics or private professionals. Applying Pierre Bourdieu’s concept of legal fields, the data suggested that both systems produce legitimacy but in quite different ways and, interestingly, that the one more similar to domestic legal systems takes that form due to political forces, not by an incremental process powered by people with legal backgrounds.
