I hope it works.
In your conduct of the investigation, it says, “...ensure that where there is reliable information”--for you to ensure, I gather--“that could affect individuals or organizations if the Independent Investigator was to make use of this information in her report,”--and this is where it gets serious--“that the concerned individuals or organizations will have an opportunity to review the portion of the report that may affect them and that their views will be sought before the report is finalized”.
Now, if there's something in your report, can they actually take it out, or is it something that's relative to a legal impact on somebody else? It seems to me that you're drafting a report. You have statements from individuals. They can double-check that report to see if they want it released or not.
