A scientist escaped a charge of speeding at 42mph, after claiming a device he invented showed him travelling 12mph slower.
A spokesman for the Crown Prosecution Service (CPS) said: "The officer who operated the camera has since retired.
"Without his verbal evidence, we could not prove the case to the required standard." :whistling:
