If a licensee is a partnership or corporation, it shall be sufficient cause for the denial, suspension, or revocation of a clinic license if any, owner, operator, officer, director, or trustee of the partnership or corporation, or any member in the case of a partnership, has committed any act or omitted any duty which would be cause for refusing, suspending, or revoking a license issued to him as an individual under this chapter. Each licensee shall be responsible for the acts of any of his instructors while acting as his agent, if the clinic approved of those acts or had knowledge of those acts or other similar acts and after such knowledge retained the benefit, proceeds, profits, or advantages accruing from those acts or otherwise ratified those acts.
