Steven Finizio and Ross Galvin compare the different approaches to the allocation of costs in international commercial and investment treaty arbitration, and include an analysis of treaty decisions since 2014, in a chapter appearing in Finances in International Arbitration: Liber Amicorum Patricia Shaughnessy (2019, Wolters Kluwer).
The authors conclude that there continues to be no universally accepted approach, but that a majority of recent treaty cases have used an approach similar to the approach seen in commercial cases.
