The appropriate boundaries of those conversations are exactly the issue of the Shawcross doctrine, and I would point everybody on the committee to “Open and Accountable Government”, which is the Prime Minister's playbook. There was one from Prime Minister Harper with similar language, and there is one that was issued by the Prime Minister in November 2015. It specifically refers in detail to the Prime Minister's view of what is appropriate and not appropriate in terms of dealing with legal matters.
