The Latin maxim 'qui facit per alium facit per se' means 'he who acts through another acts himself'. This maxim establishes the principle of vicarious liability, where a principal is held liable for the wrongful acts committed by their agent or servant in the course of employment. It is not related to the Indian Penal Code, Indian Contract Act, or general tort liability - it specifically addresses situations where liability is imputed from one person to another based on their relationship.
