Composition of ad hoc Committees Implications Nicolas Angelet

I. Policy Issues A. International and Institutional Proceedings No party appointments (Article 52.3) In lieu of domestic control (Article 54) → Legitimacy towards State Parties → Avoid (perceived) domestic or ‘partisan’ influences

I. Policy Issues B. Annulment proceedings Open-ended grounds Directed against award = potentially affecting the arbitrators (cf. Article 52.3) → Legitimacy towards State Parties : avoid domestic or ‘partisan’ positions → Fairness towards the arbitrators : maximize coherence = legal certainty

II. Familiarity with the legal system involved in the dispute? A. Broches et al.: “the requirement of familiarity with the legal system(s) involved may present another obstacle” to continuity in the composition of the Committees

II. Familiarity with the legal system involved in the dispute? Not in line with: –Annulment as a substitute for domestic control, i.e., unrelated to the legal system involved in the dispute –Annulment as distinguished from appeal –Need to enhance coherence

III. Committee Members more experienced than the Arbitrators? Pierre Lalive: “.. the choice of committee members has not always been made … among more experienced people, than that of the arbitrators..”

III. Committee Members more experienced than the Arbitrators? Fairness towards the arbitrators and possibly legitimacy towards State parties Unrelated to coherence Arbitrators’ authority often cannot be outclassed Experience in what? ICSID arbitration, ICSID annulment proceedings, domestic proceedings directed against arbitral awards

IV. Int’l and Domestic Lawyers Different Legal Cultures Public international lawyers: –Advantages: grounds for annulment as treaty law public international law issues raised under a ground of annulment safeguarding proceedings against domestic influences –Limits: few public international lawyers experienced in proceedings against arbitral awards

IV. Int’l and Domestic Lawyers Different Legal Cultures Domestic Lawyers: –Advantages : larger number with relevant experience –Limits: risk of undue domestic influences – compensation through representation of different legal cultures

VI. Continuity in Composition Observations ( Present) Out of 38 persons, 11 have served more than 1 time Generally, not in successive Committees 7 have served in 2 different Committees 3 have served in 3 different Committees 1 has served in the 4 last Committees → Return to continuity?

Conclusion Proposed criteria largely matched Recent return to continuity but loss of Investors’ State / Host State balance Danger of sacrificing other criteria to continuity ?
