[2011] EWHC 158 (Admin)
Where the prosecutor had not sought to rely on the procedure set out under the Road Traffic Offenders Act 1988 s.20, a police officer was entitled to corroborate his opinion that a motorist had travelled at an excessive speed by reference to the speed reading given by a speed measuring device that was a prescribed device but which was not of an approved type.
