For the most part, I would hesitate to use the word “frivolous”. I think that's wrong. “Vexatious” might be a little bit closer, but I certainly agree with my colleague's view that sometimes, perhaps increasingly, there are fishing expeditions. People make a request for email subject headers. They're not requesting information. They want to know what's on the menu before they decide what to order. In this context, I'm not sure that's what the act was originally intended for. Certainly the act goes back to 1983. There was no email at that point, so I don't think that's what was intended.
I think to the extent that we can avoid requests like that.... They take up a lot of the time of the people who are being requested and also the people processing the ATIP request, and it would be nice to be able to limit those in some ways.
