The Portuguese Constitution (CRP) stands out for its clear international agenda, particularly regarding cooperation with Portuguese-speaking states. Unlike its limited influence in broader European federalist structures, Portugal plays a significant role in the Lusophone sphere, where constitutional provisions translate into tangible policies, such as special rights for Lusophone citizens and the CPLP. The author argues for a shared Lusophone constitutional identity, rejecting the notion that this is a form of post-colonial dominance. Instead, it is a circular exchange of legal solutions that fosters a 'constitutional humanism of the Lusophony,' characterized by robust fundamental rights protections and sophisticated systems of judicial review.
