I think it was in 1984 or 1985 that the CSIS Act was put in. Probably at the time it was to give independent eyes and ears for the minister, different from the external review body of SIRC. I think, though, what's going on here is no change to the proportion or amount of review that's going to be done. Two-thirds of the CSIS Act still deals with accountability and reporting and review. That proportion stays the same. It's one function that is done in many ways already by SIRC, but it's going to be done specifically in a different place.
