The concept of 'directing mind and will' is used to confer liability on the top management personnel who collectively represent the mind of the company and are responsible for negligence or fraud committed. The directing mind of the company refers to any individual acting as an agent of the company with authority, highlighting that the state of mind of the company essentially refers to that of its agents, including the top management. This concept can lead to liability not limited to the company but also to the individuals involved, although there are safeguards such as the business judgment rule to escape liability. The limited liability of a company can be pierced in certain circumstances, such as serious corporate frauds or under-capitalization, where the court may hold shareholders or owners responsible for outstanding liabilities.
