A former student at the now-defunct ITT Technical Institute and his mother are suing student loan giant Navient (NAVI) over the company’s refusal to cancel his private student loans despite the U.S. government erasing thousands of federal student loans related to the notorious for-profit school. The case could set a precedent for defrauded borrowers seeking relief from privately-held loans (as opposed to federally-backed loans).

For roughly a decade, Jorge Villalba has been contending with student debt that he believes — and the government has confirmed — he was illegally misled into borrowing. Villalba, 39, attended ITT Technical Institutes, a major for-profit college chain, from 2006 to 2010. Just six years after he graduated, ITT filed for bankruptcy, amid allegations the school used misleading job placement and graduation rates to convince students to sign up for classes and take on the loans that would pay for them.

Today, a new lawsuit was filed against Navient, the student loan servicer formerly known as Sallie Mae. The suit was filed by the Project on Predatory Student Lending at Harvard Law School on behalf of Jorge and Alicia Villalba.

A proposed court settlement between the Trump administration and defrauded borrowers is in jeopardy after the administration revealed its widespread denials of requests for student debt cancellation. Ninety-four percent of the debt relief claims the Education Department has processed since reaching the agreement in April have been rejected, the department said in a court filing last week. The federal agency issued 78,400 decisions, of which 4,400 were approved and the remainder denied.
