XVI, Sec. 5 Special investigator

Here's a plain-English summary of this rule:

If a case needs extra help while it's being looked into, the Commission can bring in a special investigator to work on it. This person's job is to collect evidence and present it to the Commission. The Chief Justice has to approve this step before it can happen.

The Commission can also give this investigator other tasks connected to the investigation. Basically, this rule gives the Commission a way to add outside help to make sure the investigation gets done properly, but only with sign-off from the Chief Justice.
