You cannot sue to force any federal agency to do anything that is a discretionary act, and most things agencies do are discretionary, like enforcing the law. You may complain to the Secretary of Education, the President, and your congressional representatives about what you regard as insufficient action by the agency, however.I appreciate the tip, but note that I'm not really interested in a personal remedy. I went to the DoE because I wanted the DoE to pressure the school to start to abide by FERPA for the benefit of future students. Now that the DoE refused to do their job, I want the DoE to get an "F" on their report card. I'd be satisfied if some kind of public record were made that the DoE did not do their job, ideally seen by whoever the DoE answers to. If that's simply POTUS, then I guess it's a lost cause.
