Yes, but according to the Speaker, the government complied without actually explaining why it had not released all the documents and why some of them had not been provided. The Speaker indicated that an explanation had to be provided to the House of Commons, to members of Parliament. I believe that is the reason why he decided to accept the prima facie question of privilege and allow the committee to look at the issue more closely. At the various sittings of this committee, the government may provide a more detailed explanation of why it decided not to release the documents.
