Global Constitutionalism: A Necessary Neologism or a Mere Cachophony?

The evolution of globalisation caused a reciprocal process of constitutionalisation of the International public law and internationalisation of the Constitutional law, at the same time that the exercise of global governance was developed. Global constitutionalism is one of the most successful approaches so far as a means to study this phenomenon, especially in the English and German literatures. In spite of this fact, it still lacks an agreed definition, and it continues without establishing what its scope is. The objective of this article is to analyse this neologism and its several meanings, collecting the most relevant contributions. After distinguishing it from the close concept of international constitutional law, a binary logic is applied to ordering the approaches that defend or deny the feasibility and convenience of translating the constitutionalism's traditional topics to a global context of legal pluralism.
