This makes it clear that the Government is working within the legal stipulations set by Dominic Grieve’s political chicanery, and is responding in kind. So there is nothing unconstitutional or improper here. And if the Commons does not like the move, then it is free to pass a motion of no confidence in the Government. As long as a majority of MPs have confidence in the Government, but disapprove of its Brexit policy, they cannot complain about any legal and constitutional means the Government employs to achieve its objectives.
