Liability of employers for acts of employees

(1) Any act done or conduct engaged in by a person in the course of his employment (referred to in this section as the employee) shall be treated for the purposes of this Act as done or engaged in by his employer as well as by him, whether or not it was done or engaged in with the employer’s knowledge or approval.
(2) In any proceedings for an offence under this Act brought against any person in respect of an act or conduct alleged to have been done or engaged in, as the case may be, by an employee of that person, it is a defence for that person to prove that he took such steps as were practicable to prevent the employee from doing the act or engaging in the conduct, or from doing or engaging in, in the course of his employment, acts or conduct, as the case may be, of that description.
