"Most Sensible, and not at all Unappreciated; and yet, shall we go Together to the Palace now and Demand her Immediate Release into such Secure Lodging as has been Prepared? Perhaps consulting the Church of Iomedae as regards Exceptional Security, or the Reclamation, or even that which I may provide Personally? I have of course made Demands along such Lines and am Empowered to so Consult. Did Sirmium consider himself to Arrest a Criminal; did you; from Whence does this Detention as of a Notorious Criminal, yet without Formal Charge, arise? If there is no such Theory to be found it is of course Well for me, showing forth the Arbitrary Flimsiness of any Purported Case."
It would be nice if there were some bright line to follow and cite rather than contradictory gleanings from old books. The Crown has arbitrary power to detain, but the basis for detention is sometimes able to be challenged, and all in all no one knows what the law is supposed to be right now, a darkness well suited to casting salutary doubt on everything.
