For a warrant to be authorised, an affidavit must be read and agreed to by the authorising authority, confirming there is a case and agreeing with the charges stated in the warrant.
“One of them would have the authorised that warrant, and for one to authorise the warrant, you therefore have to read first this affidavit, and to say, yes, we have a case, I agree with this, and the warrant also states the charges, I agree with the charges. Then the prosecutor authorises that.”
