The document discusses the principle of vicarious liability under tort law. It provides examples where vicarious liability may arise such as between a principal and agent, partners in a firm, or a master and servant. The key aspects discussed include the relationship that must exist between the wrongdoer and the liable party, that the act must have occurred in the course of that relationship/employment, and the justification for imposing vicarious liability including deeper pockets of the employer to pay damages and encouraging accident prevention. It also provides a case example where a court held a municipal corporation vicariously liable for failure to properly barricade and sign a construction pit, even though work was contracted to others.
