Brexit Innovations

Yvette Cooper appears to be genuinely innovating with her bill to prolong the Article 50 date.  Traditionally, bills have been forward by the Queen-in-Parliament so this really is quite new.  What the EU Commission are going to make of it I can't imagine.  We tend to find our own constitution very hard to understand so I imagine non-British people find it utterly bewildering.  I take it that it makes a fresh set of elections to the European Parliament inevitable if it gets through.
