[2010] EWHC 2357 (Admin)
Magistrates had not been entitled to find that a speed measuring device had been approved under the Road Traffic Offenders Act 1988 s.20 solely on a police officer's evidence that it was widely used, nor was it appropriate to affirm on a different basis the speeding conviction they had consequently passed.
