Domenick Lucenti (plaintiff) worked for Greg Laviero and Martin Laviero Contractors, Inc. (defendants). He was injured at work in an accident involving an excavator that only worked when it was “rigged” to operate at full throttle. Before the accident, Lucenti and other employees had warned Greg Laviero about the dangers of using the rigged excavator. There had been no other serious accidents involving the excavator and no history of workplace-safety violations involving Laviero’s equipment. Lucenti sued Laviero in state court seeking damages for his injuries. Laviero moved for summary judgment, asserting that it was exempt from liability for civil damages under the exclusivity provision of Connecticut’s workers’-compensation statute, which bars employees from bringing common-law tort actions against their employers for job-related injuries. The trial court granted Laviero’s motion, and the appellate court affirmed. Lucenti appealed to the Connecticut Supreme Court.
