AIG unit loses cover ruling in church sex abuse settlementAn American International Group unit must again defend its refusal to cover settlement costs the Church of Jesus Christ of Latter-day Saints paid to resolve child sexual abuse claims, after a federal appeals court found the insurer’s policy language ambiguous. The case had been on appeal from the U.S. District Court for the District of Utah. The district court agreed and granted summary judgment to the insurers. In another sexual abuse case, he wrote, defendant Ace took the opposite position — that dozens of sexual abuse incidents stemmed from an institutional coverup that counted as one occurrence. The case returns to the district court for further proceedings.
