In terms of the 2010 precedent, it was the ministers who appeared instead of the political staffer. The opposition, many members of the committee, were concerned with that position being taken. There was a debate on a motion to report that to the House, and that was defeated at committee, so that motion was not adopted.
These are the types of issues that we see arising. A government will take a position, and committees will consider that and whether they accept the reasons—or not—given by the government in those instances. My view is that, ultimately, it is up to the committees and to the House to make the determination. The determination may well be that it's appropriate to have a different witness for different purposes or different types of information. These are considerations for the committee.
