How is world law different from the international treaties already in place?

Law requires a legislative body to enact it, and an executive body to administer and enforce it. These institutions make up the essential governmental framework. So-called international law lacks these bodies, rendering it merely a matrix of multilateral treaties between equal and independent sovereign states. Neither the individual nor humanity itself is or can be represented by “international law,” as there is no body or institution that oversees the enforcement of these laws.
