Federal and state courts tackled many interesting insurance-related issues this past year. Perhaps no state had a more impactful year than Illinois, which held that construction defects could constitute an occurrence, that a LEG 3 "extension" attempting to preclude coverage for faulty or defective workmanship was ambiguous as a matter of law (applying Illinois law), and that ostensibly prohibitive "catch-all exclusions" can render policy language ambiguous in favor of coverage.
