Legal Principle: A parent is not liable for tort committed by his/her child except when the parent affords the child an opportunity to commit to the tort.
Factual Situation: A mother takes her seven-year-old son with her to market. On reaching the market, she shuts the car ignition, pulls the handbrake and puts the car in gear. She leaves her son in the car only. The child starts playing in the car and while doing so he releases the brakes and pushes the gear lever to neutral. As a result, the car starts moving down the road and runs down a pedestrian.
Question: What is the liability of the mother?
