I suspect JudgeJ means anomalous rather than false.
To assume what you may have seen must be false simply because the rules say it shouldn't happen would at best be foolish and at worst display a total detatchment from reality.
Take this for example:

This does seem a pretty clear example of a magistrate misinterpreting the rules - I don't know if the prosecution can appeal in cases like this but hopefully at the very least somebody had a word with the magistrate and put her straight.
I mean what is the point of guidelines when JPs still seem to think they know best? anyone would think they were professionals
