barry beavis launched a legal bid to overturn his fine , saying it was unfair , disproportionate and unenforceable .
but in a landmark ruling , appeal court judges decided the size of the fine was neither ` extravagant or unconscionable ' .
motoring groups reacted in fury to the decision , accusing the judges said the fine was enforceable because it was not ` excessively high ' .
but yesterday judges said the ruling was a victory for the parking cowboys .
