This is just to bring the rest of the bill into conformity. It was based on hopes that there would be sufficient support in this committee to extend the 90-day deadline to a possible maximum of 180 days. Given that the amendment was in fact adopted by the majority of the committee, this follows logically in clause 7 as it now stands. As clause 6 talks about the 90-day deadline, this simply corrects it to the 180-day deadline, as does the Liberal amendment number 5.
On November 23rd, 2010. See this statement in context.
