obtuse - I don't think you have this correct. It is difficult to discern without looking at the entire record whether the school discriminated on the basis of gender. If they did, and it can be proven, then the school violated the law. EEO law doesn't permit discrimination based on gender. It does require institutions not to discriminate, and meet diversity goals in hiring.
And I don't understand the notion you raise about the job description favoring men. Maybe it did, or maybe it didn't. But you don't know what it stated. Moreover, merely having a surplus of men apply does not automatically mean that the description was discriminatory.
From an optical standpoint, the school seems to have done this poorly. If they appear as if they going to select and select until they obtained the right gender, well, operating towards an unstated quota will not help them. But they have a chance to defend their position in court, so we will see.
