The Seventh Circuit agreed with the district court that it would be inequitable for White Mountains to benefit from National Casualty’s attempt to do the right thing, especially since White Mountains did not do the right thing in a situation of questionable coverage and contribute to the defense costs under a reservation of rights. White Mountains is liable for the defense costs of McFatridge and Edgar County as found by the district court. National Casualty is not liable for the defense costs under McFatridge I, 604 F.3d at 345. We also note that there appear to be no other parties liable for McFatridge’s and Edgar County’s defense costs. McFatridge had previously claimed that the State of Illinois was also responsible for his defense costs, but as noted earlier, the Illinois Supreme Court has recently clarified that the State is not liable for these costs. Madigan, 989 N.E.2d at 173. Therefore, White Mountains alone was unjustly enriched by National Casualty’s expenditures on McFatridge’s and Edgar County’s defense costs, and White Mountains must reimburse National Casualty for these expenditures.
