Livingstone, the law and the Labour Rulebook
So Ken Livingstone has won his High Court appeal against the Adjudication Panel for England's finding that he brought his office into disrepute over "unnecessarily offensive" and "indefensible" (according to the appeal Judge) comments made to Jewish journalist Oliver Finegold.
But as far as I know he has never been investigated by the Labour Party over whether his "unnecessarily offensive" and "indefensible" comments "brought the Labour Party into disrepute", an offence under Party rules. To the extent that they may have turned many Jewish voters off voting for a Labour Mayor of London, it looks like prima facie there is a case to be investigated.
The CLP where he lives, Brent East, could have looked at this.
The Chief Whip of the GLA Labour Group could have looked at this.
The NEC could have looked at this.
If he was a councillor (and if he was his comments would have received less publicity and hence damaged the Party less) they would be likely to have resulted in a Labour Party disciplinary investigation. That may have cleared him but at least it would have looked into the matter.
But, as with his rulebook-bending readmission to the Labour Party without serving the 5 year membership ban for standing against a Labour candidate, there is one Rulebook for Ken and another for the rest of us who hold public office, and indeed the wider membership.
