It would be welcome to see somebody taking that forward. I consulted the Attorney General in Northern Ireland about this issue, which has been placed on the agenda at an international level. I believe those discussions on an international treaty not being upheld take place in Vienna. At one stage, the commission was considering going down that road. However, the Attorney General said that is where it would have to happen but that it would have to fall to one or other of the Governments to take it.
