We argue the possibility that a real part of M_\nu only respects a \mu-\tau symmetry.  This possibility is shown to be extended to more general case with a phase parameter \theta, where the \mu-\tau symmetric part has a phase of \theta/2.  This texture shows maximal CP violation and no Majorana CP violation.
