Abstract

It is argued that superselection rules originate not from symmetry but from the initial state of the universe. This solves the puzzle posed by Schroeren in his recent paper "The Global Phase Is Real"; since the SO(3) symmetry does not imply the univalence superselection rule, his argument for the reality of the global phase does not succeed.
