Abstract
Movements tend to employ instituent practices and to acquire constitutive characteristics when they set up the material foundations of their collective autonomy, i.e. when they establish socially reproductive commons, democratically producing forms of life that respond to basic needs of the participants to the commons. The legal recognition of the sphere of the commons and the freedom of people to share, co-establish and self-regulate whole infrastructures of their social production is therefore not a negligible change but a complete reversal of the logic currently underlying our legal order. It is, therefore, clear that to the end of multiplying and expanding the sphere of the commons we need to invent a new theory of a law of the commons and a hybrid and transitional semi-state ius communis, which will be capable of incorporating the acquis of social movements and receptive to emerging forms of life of the oppressed
