Speeding, Glasgow JP Court, May 2016. This speeding case involved a Unipar laser gun and two police witnesses. Our client was adamant that he was not speeding and that there must have been an error with the Unipar gun. One possible source of error can be that the police do not activate the correct mode on their airwave radio devices. This mode is similar to activating ‘flight mode’ on a mobile phone when on an aeroplane. Failure to do so can mean that the device interferes with the Unipar gun, resulting in a false speed reading. In their statements, neither police officer mentioned whether they had activated this mode and we therefore asked the Crown to disclose the records from the device. The Crown refused to do so , compelling us to go to court to seek a legal order for the records. The court agreed and the Crown was compelled to hand over the records. When we analysed the data, it was clear that one of the officers had failed to set his device to the correct mode. The case nevertheless proceeded to trial. We cited an expert to give evidence about the importance of the records. Faced with this, the Crown moved to adjourn the trial. We successfully opposed the motion and the case was deserted. The Unipar gun, according to its manufacturer and according to the police, is one of the most reliable speed measurement devices available and the courts are often all too ready to agree. Our position is that the gun is simply a user-operated machine. It can go wrong and, moreover, is only as reliable as the person using it. It is not easy to win a speeding case involving a unipar gun but, time and again, we have proved that it can be done.
