This is exactly what triggered the question. I mean, honestly, claiming that US might have the greatest system along with other developed countries points out just how fragmented global legal system is. I consider such a reference ignorant although it’s more of a systematic fallacy.
Going through the process of writing a master thesis (Global Law: Between Concept and Reality) where the first chapter focuses on the relevant actors got me thinking. Yes. International law might be a collection of all legal sources made by nation states... But, let’s be frank, states (developed and developing) have been prime political and legal contributors for centuries. After Rousseau. Those centuries have passed.
Today many multinational corporations’ (who am I kidding, even individuals’) budgets surpass the budget of a lot of developed countries, while there’s countless types of organizations emerging cross borders and influencing decision-makers on numerous levels.
Global law should proclaim all actors (organizations) not equal, but at least pro-rata responsible for their (in)actions.
A great global legal system starts there. And the rules we create through those modules and fragments are not only Treaties, “laws”, MoUs, CoC, T&C, (love me some abbreviations, sounds so smart and nerdy!) but should in the first place be customs and good practices. Moreover, the effectiveness and abidance to the “rule of law” is all about traceable and measurable impact we create by executing what we agreed upon (including the hidden calculations of withdrawing and breaching said agreements). Big data. Legal data. Global data. Smart data. Call it whatever. These things collected, processed and utilized in a way that benefits humanity as a whole will create GREAT LEGAL SYSTEM.
US is a joke.
