The assignment discusses tort laws, specifically duty of care, breach of duty, causation, contributory negligence, and voluntary assumption of risk. The case study involves Michelle driving drunk with Rebecca as a passenger, leading to an accident. The discussion concludes that Michelle owes a duty of care to Rebecca, breached that duty, and caused the injury. Additionally, it is argued that Rebecca contributed to her own injuries through contributory negligence and that Michelle can rely on the defense of voluntary assumption of risk.
