It was up to the prosecution to prove the case. This they failed to do. They knew they would be confronted with probably the most impressive defence team in the world, and their case amounted to a testimony from dubious, discredited hustlers.

Whilst this may have been enough to do deprive a teacher of his living, or send any number of public servants to jail - it was never going to work in this case...

not much cause for celebration any way you look at it.
