In this attorney malpractice case, the trial court properly ruled against plaintiff on the case-within-a-case, establishing that the underlying insurance claim had no merit, so the attorney’s negligence in not filing suit in a timely manner did not cause plaintiff’s loss. The insurance claim arose under a contractor’s CGL policy, and the policy’s own work exclusion clearly barred insurance coverage for property damage caused by the contractor’s own faulty work. The decision explains that the exclusion avoids moral hazard of tempting the insured to engage in cheaper, faulty work, and for that reason the exclusion applies to any property damage caused by the contractor’s own work, whether within the scope of the construction contract or not. The decision also affirms the trial judge’s finding that plaintiffs didn’t have a separate claim for personal injury (which would be a covered loss) from an alleged slip-and-fall on a faulty staircase. Though the plaintiff’s testimony about the fall was undisputed, other evidence–namely, failure to mention the injury in earlier listings of covered losses–rationally supported the trial judge’s finding that the testimony lacked credibility. As no loss was covered by the insurance, the attorney’s negligence did not cause plaintiff’s loss.
