Well if you don't live here what are you moaning about?
If you are scred of proper border checks what are you hiding?
The Good Friday Agreement stipulates that any Irish citizens, which includes those with Irish passports living in the north are allowed to reside anywhere on the island of Ireland. In other words, there cannot be any checks on peoples' movements, therefore there cannot be a border that checks the movement of people on the island of Ireland. As the Good Friday Agreement is an international treaty signed by two sovereign governments and lodged with the UN, it can't be amended, repealed or torn up. The government spokesperson was forced to admit this in parliament yesterday.
The Northern Ireland Act 1989 is different and is now the focus for amending as it stipulates that the Stormont assembly can only pass laws that are compatible with EU law. If not then it goes to the ECJ for a ruling. The Tories will have to try and amended this. However, the GFA and the Northern Ireland Act were signed in conjunction with changes in the Irish constitution. The UK government repealing the Northern Ireland Act will mean the Irish government can alter their constitution back to claiming the north as part of Ireland.
Any changes to any of the 2 signed agreements by a UK government, will mean there will be a push for a border vote on the status of the north of the island of Ireland.
If the north is unified with the south, then the UK government can then give the NHS the £350 million that Northern Ireland gets every week.
