That article is ridiculously sympathetic.
The two costs are unrelated to each other.
The defendant chose to contest the conviction, as is their right.
They lost, so costs (substantially reduced, I might add, so still leaving the taxpayer with a hefty bill) were awarded.
So why the spurious attempt to paint the costs as "unfair" in relation to the original fine?
Maybe next time she'll:
- think twice before breaking the speed limit
- not waste everyone's time with a ridiculous defence
I'll just add that he must be a poor physicist to argue that a speed camera is not effective on a bend because light travels in a straight line!
You'd have be travelling extremely fast for that to make more than 0.00000000001% difference to the recorded speed (light travels at c. 186,000 miles/second)
