July 14 was a bad day for Yvonne. On that day she went to her friend's (Justine) house for lunch. The day before, Justine's son, Dominic, had kicked his soccer ball through the glass sliding door which opened on to the sunlit patio. Whilst Yvonne was on the patio she tripped on a crack in the patio floor and seriously injured her arm on the broken glass in the door. Whilst waiting in the hospital casualty rooms an emergency car accident victim was brought in - Yvonne recognised the "glow in the dark" school bag lying on the end of the stretcher. The bag belonged to her son, Jacques. Jacques had serious spinal injuries and the doctors held grave concerns for his future. Yvonne went into shock and suffered psychological injuries. Apparently Jacques had disembarked from his school bus and went to cross the road in front of the bus. The road Jacques was crossing was Pennant Hills Road, a very busy four lane highway. At this time the cars in the two lanes on the other side of the road were stationary and banked up. Jacques stepped out from in front of the bus into a car being driven, at a moderate speed, by Mary. Discuss the actions in negligence, only, that Yvonne may take against Justine, and Mary, on her own behalf and on behalf of her son, Jacques. Fully discuss, using relevant authority, these actions in negligence, and the likelihood of success.
