A point I often make on these threads is that referring to EU law genetically can be misleading.It gives the impression all our laws are subject to EU influence.They are not.
I snapped at a neighbour the other night who confidently said he'd be able to get a rejected planning permission after we leave the EU. Planning is a classic example of entirely domestic legislation.
We and all member states agreed remit was only some common regulation in agriculture, environment. product safety and some basic employment rights.
France, Germany, Spain (and us) etc never suggested overall shared legislation.Defence, education, schools, universities, hospitals, NHS, elderly care, local government, defence, tax, inheritance, social care, disability benefits, fiscal policy, property, planning, criminal law, prisons, policing,marriage, children matters, family law, non EU immigration.
