10 Statements or Submissions on Costs

This chapter considers the duration and costs of investment arbitrations as well as the procedural mechanics of cost submissions or statements of costs. It first examines the timing, format, and content of cost submissions and statements of costs before discussing the relevant arbitral rules that govern such submissions in International Centre for Settlement of Investment Disputes (ICSID) Convention and ICSID Additional-Facility arbitration proceedings, along with the average amount of such costs. It then explains the UNCITRAL Arbitration Rules on costs submissions, taking into account the average amount of those costs, and the duration of arbitration proceedings. It also analyses how arbitral tribunals have allocated costs in ICSID and UNCITRAL proceedings and highlights the factors deemed relevant by tribunals in those decisions.
