The common law test to impose criminal responsibility on a company only arises where a person's gross negligence has led to another person's death and (under the "identification doctrine") that person is a "controlling mind", whose actions and intentions can be imputed to the company (that is, a person in control of the company's affairs to a sufficient degree that the company can fairly be said to think and act through him). This is tested by reference to the detailed work patterns of the manager, and the job title or description given to that person is irrelevant, but there is often no single person who acts as a "controlling mind", particularly in large companies, and many issues of health and safety are delegated to junior managers who are not "controlling minds".
