The Editorial Board writes:  Today, Sweet Briar College formally inaugurates Meredith Woo as its 13th president.  This, of course, was a day that wasn’t supposed to happen. If Sweet Briar’s board — the old board, that is — had its way, the women’s college in Amherst County would have closed in 2015 and the expansive 3,250-acre campus today would be . . . well, who knows? Not a college, that’s for sure. A determined band of alumnae had something to say about that. So did the courts — the will of the college’s founder specified the college was to be a “perpetual memorial” to her daughter. That was a key legal detail that stood in the way of the board’s attempt to close the school.
