To argue tendered termination of A50 by UK gov in lieu of its agreement to 19 Mar 2018 draft settlement (in progress) does not obviate the necessity of its own draft and its acceptance by the Council and EP before 3 March 2019 plenary session.

Apparently there is no form transmittal.

What might this UK document say? Are UK gov and parliament capable of agreement in themselves as to which domestic laws (nacted to date in anticipation of "frictionless" trade) they will admit and which they will repeal? How much time for reconciliation might UK gov stipulate? Further, is UK gov and parliament, under separate cover as they say, willing and able to compensate claims by interested private persons of "damage" by the proceedings of the A50 notice delivered?

Think about those consequences then speculate as to whether unanimity or qualified acceptance of this novelty by the EU Council and EP would or should be forthcoming.

Diversity is the key to economic and political evolution.
