HACKSHAW V. SHAW  155 CLR 614
High Court of Australia – 11 December 1984
Shaw was the owner of a farm where petrol was stored for farming machinery. The petrol was being stolen at night and Shaw decided to ambush the next thief of petrol. He therefore lay in wait near the petrol tank.
Hackshaw was in a stolen motor vehicle with Cox when Cox drove into Shaw’s farm, with the headlights turned off, and started stealing petrol. Shaw fired two warning shots at the car and hit Hackshaw who was in the front seat.
It was accepted that Shaw had not known that Hackshaw was in the car. Hackshaw sued Shaw seeking compensation for her injuries.
