It was also, as I mentioned, our effort to fulfill a recommendation made by the House of Commons committee that originally reviewed these two powers. They were concerned that the law was unclear as to how long a period of detention there would be for someone who was arrested pursuant to a warrant to attend that investigative hearing. Now the law, under Bill S-7, will be very clear that the maximum period of detention can't be any more than 90 days, and I stress “maximum” period of detention. Under section 707, if I recall correctly, every 30 days the judge has to determine whether the witness should continue to be detained.
