Asked if it would be common for an investigator to make a disciplinary recommendation in such a case, Lockhart said: "No. In fact, at Kia's level, she wouldn't, and she didn't. She made her point of view on particularly the credibility issues known in the report; they are reflected in the report. It is the commissioner and the commissioner's sole role to decide on discipline. In fact, the union filed a grievance to force him not to delegate the decision" on disciplinary decisions under the personal conduct policy that was strengthened in Dec. 2014.
