Professor Colin Harvey:

The British Government needs to respect its international legal obligations. There are weaknesses in relation to enforcing those, and the Irish Government is limited in what it can do. That does not undermine the fact that there is an international legal obligation on the UK Government to implement in good faith, by amending its domestic law, in order to reflect this crystal-clear birthright guarantee. That we are sitting here 21 years later talking about this is frankly remarkable, and should give pause for concern to everybody who is currently in negotiations with any British Government about any political agreement now or in the future.
