It looks to me as if Unite have taken the judgement,
misunderstood some of the wording and then put their own spin on it for their members.
As Bill of the Hamptons says, the Unite legal team recognise a good earner when they see one and so they are more than happy if Unite appeal.
It's worth reading the Judge's words again:
how can I condemn the less than extreme changes as unreasonable?
There is no point in flogging a dead horse.
