Formal investigation can be ordered in three ways. Firstly, it can be when a preliminary investigation opened under section MIE-1.11 can be converted into a formal investigation based on the findings, facts and evidence gathered during the preliminary investigation. Secondly, prior to completion of the preliminary investigation, it may be determined that it would be appropriate to order a formal investigation on the case. Thirdly, a formal investigation can also be ordered without any history of a preliminary investigation on the matter.
