Certainly in comparison to warrants for law enforcement, the mechanisms are different. Part VI Criminal Code warrants have different requirements for reporting back—even disclosing to the person under investigation that they were the subject of a warranted activity. Those requirements are absent in national security warrants for very good reasons that we don't have enough time to go through, but there is no doubt that there is not the same accountability. However, rest assured, as we've seen with a couple of warrants that are referred to as DIFTs—domestic interception of foreign telecommunications—for targets involving a CSIS and CSE collaborative effort, the Federal Court went back and made a very clear pronouncement that it was not pleased with one part of that activity. So there is opportunity and there are some forms of review.
