Abstract: This paper divides in two parts. The first part elaborates
on the difference among categories of "legalities" that have developed
on the globe, and considers their shapes and thickness as irreducible to
the uniform notion of a "global law". Different pictures and
explanations affect sensibly in epistemic and pragmatic sense the
understanding and the potential of the law in relation to global
governance. It is the very fact of metamorphoses of law along diverse
legal "formats" (one has to think of WTO, ISO, ICANN, WHO, ICLOS- about
2000 specialized global regimes-, of the newly coined "Global
Administrative Law", of transnational merchant law, of regional order of
the EU, of the international legal order, of State orders, and so
forth).
