On new metaphorical applications of the Schrödinger’s Cat thought-experiment or joke and the need for a new legal test case, in the context of #Brexit

Until an observation forces the system into one of the two equally probable cat-life eigenstates, the box contains the linear superposition of half a dead cat, and half a live cat.
Before we get close again to a default, no-deal Brexit, perhaps next time with no extension on offer, it’d be nice to discover the British PM’s as-yet-undisclosed belief as to the correct answer to an unresolved constitutional question. That question is what the constitutional requirements are for revoking the Article 50 notice already given.
A key question within that is whether there would need to be a new Act of Parliament before the PM could revoke Article 50 notice. What does the PM think is the answer to that? It’s not at all clear from the news what she thinks.
