No, she doesn't bypass Parliament, Mr. Chairman. The government may through order in council ask her to do a special investigation into a special issue, and in response to that request by the order in council, by the government, she therefore has to respond back to the people who commissioned the report in the first place, being the government. Normally, as an officer of Parliament, she is given statutory powers to conduct her investigations and report to the House, but there is also specific legislative authority to respond to requests by the government.
