See it is a nightmare. Grandfather clauses are not unusual in cases such as residential rights. My understanding is that I would be entitled to apply for a UK passport in the grounds that my father and indeed my mother was born in Ireland pre 1923. , A date when the treaty between UK and the Irish Free State as it was then called. came into effect. I have no such intention, so will not be confirming that. My children would not however have that as a right.So despite leaving the EU and withdrawing from the ECJ influence, our laws related to EU immigrants are frozen for up to 100 years until the most recent babies brought in have died?
And during that circa 100 years we are subject to any changes in the application of the law the ECJ chooses, without any input or control from us?
I think not.
Anyone moving to another country knows they will be subject to that countries laws and any changes in those laws that country chooses to make. There is no possible justification for EU citizens here to be treated any differently than that time honoured common practice.

What transpires will be in the detail yet to be decided.
