Abstract
In a gauge theory at nonzero temperature the eigenvalues of the Wilson line form a set of gauge invariant observables. By constructing the c orresponding partition function for the phases of these eigenvalues, w e prove that the trivial vacuum, where the phases vanish, is a minimum of the free energy.
