I will perhaps ask the deputy commissioner to comment after I make an initial comment, Mr. Chairman.
In the dialogue that takes place with the complainants, if it is frivolous, they can be talked out of it, and quite often, the dialogue with the complainants will make the scope of a potential investigation a lot narrower. So we do everything at the front end to try to make sure the complainant understands what he or she is asking for and what the scope of the statute is, because there is often not a lot of good understanding of what can be asked for and why it can be asked for.
But on the comment as to whether many of them are frivolous, I'd have to ask the deputy commissioner to respond. I don't get that sense early on in the game, but I'll let Mr. Leadbeater comment.
