  World government proponents seek a highly centralized and federal global system. As Cabrera (2004, 71) notes, a world government would require a “restructuring of the global system to bring states under the authority of just supranational institutions.” A central government would sit at the core with autonomous and coercive decision-making potential. As with cosmopolitan democracy, a world government would also entail a directly-elected global parliament, empowered courts, and a singular global constitution which explicates basic rights and duties for all. In many cases, proponents stipulate that a world government could come about through a major recalibration of the United Nations General Assembly. Famously, Habermas has also argued for a three-tiered hierarchical global system in which supranational, transnational, and national institutions are implemented to secure rights, peace, and global democracy. Although Habermas might deny advocating a world government, William Scheuerman (2008, 148) argues that Habermas’s attempt to pursue stronger supranational governance combined with a global constitution would have that result.
