What other types of bodies...? I presume federal government bodies, at least, would be your interpretation of this wording, or could this include other bodies that can conduct investigations and are not under...?
You could imagine a situation in which some international body was conducting investigations on similar matters, or a provincial one...if there was some ambiguity around....
Again, this is the base of the question, that it's very open. What range of bodies or other types of bodies do you imagine that this would be referring to?
