ABA Journal carries the story. The ABA's letter to Villanova, here, suggests that had not Villanova volunteered the information about its false data, an appropriate sanction would have included probation or being stricken from the rolls of accredited law schools. The punishments also include several shaming sanctions.
Query: suppose the current spate of lawsuits against law schools for allegedly false numbers turns up discovery of the knowing use of false stats and suppose further that the school(s) didn't self-report. What sanctions?
