[2009] EWHC 3018 (Admin)
The fact that a laser speed detection device had not been calibrated in accordance with its manufacturer's instructions did not mean that the device was no longer of an approved type. Evidence from the device as to the speed at which a motorist was travelling was in any event only secondary corroborative evidence, as the opinion of the operator of the device regarding the speed was the primary evidence.
