A federal judge rejected claims from Harvard College that Zurich American Insurance Co. is on the hook to cover part of the costs the school incurred in defending against a lawsuit challenging its affirmative action admissions policies, a case heard by the U.S. Supreme Court last week.

In an order Wednesday, U.S. District Judge Allison Burroughs of the District of Massachusetts granted summary judgment to Zurich and dismissed the case, concluding that Harvard didn’t formally notify the company about the lawsuit targeting the school’s admissions policies until May 2017, after a notification deadline laid out in the “claims-made-and-reported” policy had passed. The missed deadline could cost Harvard up to $15 million.
