I am grateful to the organisers of this symposium on the collection, edited by Dr Baetens, on the interaction of international investment law (‘IIL’) with other areas of public international law (‘PIL’). Broadly speaking, I identify as a ‘generalist’ international lawyer, one who is interested in the system as a whole and how its organs and agents grapple with emerging problems of global governance. As such, when I was approached in 2011 to consider and address the interaction between two specialised regimes within international law, I leapt at the opportunity to consider how the law of armed conflict, and specifically, international humanitarian law (
jus in bello or ‘IHL’), a distinct legal regime that, in its modern form, has been developing through multilateral treaty practice for well over a century, would be considered within the sphere of international investment law, a relatively new area of international law that has blossomed in the last two decades, yet primarily through bilateral treaty practice and through a rich body of case law.
The results were very interesting. With abundant treaty practice in which bilateral investment treaties (BITs) embedded variously-termed clauses providing for protection and security in various forms, the interaction and possible conflict of norms between these two specialised regimes was inevitable. Indeed, factually speaking, a substantial portion of modern investment disputes have arisen precisely through the continued scourge of armed conflicts between and within States. As such, two questions needed to be considered: first, the manner through which public international law has addressed and considered the effects of armed conflicts on rights and obligations, and whether generalised, abstract rules and principles can be distilled; and secondly, whether practice in the area of investment law—specifically treaty practice in BITs and the interpretation of such treaties by specialised investment tribunals—could be said to be in harmony with the general international law framework.
