1.5. The Police Service is a disciplined body. Unless there is good and sufficient cause to do otherwise, police officers shall obey all lawful orders and abide by the provisions of Police Service policy and procedure. They shall refrain from carrying out any orders they know, or ought to know, are unlawful. No disciplinary action shall be taken against any police officer who refuses to carry out an unlawful order.
