Hidden local gauge invariance in Fatteev-Zamolodchikov quantum spin chain under open bondary conditions is studied in the framework of quantum inverse scattering method (QISM). Our results show that the Hamiltonian and its eigenvectors are explicitly gauge-dependent while the energy eigenvalues and the Bethe equations are gauge-invariant.
