The assignment discusses the concept of contributory negligence in Australian law, particularly with regards to section 9 of the Civil Liability Act 2003. The court considers several factors when determining whether a person has been guilty of contributory negligence, including the chances of harm, seriousness of the harm, and the burden imposed on the party for taking precautions against the risk of harm. The assignment also refers to case laws such as Wills v Bell & Ors [2002] QCA 419 and Jackson v McDonald's Australia Ltd [2014] NSWCA 162 to illustrate the application of these principles. In the context of the present case, Mrs. Lena Breitenfeldt can file a claim against the Wonder town Junior Cricket Club (WJCC) club for the negligent actions of its employees, but her claim would be reduced up to the extent of contributory negligence. The assignment also touches upon the concepts of duty of care and vicarious liability.
