For those who love weedy public law issues, Stephanie, Philippe and Craig finally steer back to the national security preoccupation of INTREPID, in this latest HMIROP chapter. Specifically, they mix it up (fight) over the scope of the royal prerogative over defence in Canadian law. In exchanging blows, they basically cover two issues: what is the constitutional status of the prerogative; and, whether there is any virtue in putting some matters covered by the prerogative on a statutory footing. This is not over yet.
