The section 27 referral affidavit becomes the initial primary document forming the basis of the inquiry file and can be supplemented if needed.
“the section 27, when it is sent say by complainant, that forms the basis, that is the first document that we receive that say I have seen or I suspect that such and such an offence has been committed ... And that is the first document that we have when we are opening an inquiry file as we are building up our case and investigating. Now, if it is not sufficient, we will go back and obtain a further statement”
