This case shows that Habitual Residency is not just an issue as to where someone is living. I think the court decision is in fact wrong as the links to the UK had been cut. However, I am aware of cases where people have left the UK, but continue to claim benefits in the UK. That would mean that they are inherently habitually resident in the UK. To change habitual residence is more than just flying out.
The link is to the case where Ken Livingstone appealed the decision of the Adjudication Panel for England. The Standards Board and associated Adjudication Panel have done a lot of damage to democracy in the UK. The courts are, however, bringing them into more sanity. The point about Ken Livingstone's case is that it was high profile and he also could afford to appeal. The Standard Board has a problem in that those subject to its enquiries face substantial costs that they cannot claim back. This is an issue that needs further work. In essence the Judge found that what he said brought him into disrepute, but not the office of Mayor. We do need the machinery of the SBE and APE to concentrate on things that matter rather than people being rude to each other.
