From Fragmentation to Convergence

What are the consequences for the principles of treaty interpretation and the formation of customary international law? Seminaire, Centre franco-norvégien en SHS. 

After two decades of fragmentation discourse, international courts and other bodies cross reference each other, and emphasise international law as a single, unified system of law one cannot break up into separate specialist fields. This applies to treaty interpretation, as the ICJ underlined recently in Diallo (Compensation). The same basic approach to the formation and identification of customary international law applies regardless of the field of law under consideration.

This seminar asks, What are the consequences for the principles of treaty interpretation and the formation of customary international law?
