 THOUSANDS of motorists could demand their speeding cases be reheard - after a legal blunder by North Wales Police. Letters were last night sent out to 6,500 people caught speeding on the region's roads. Many may ask their case be reviewed, resulting in costly court chaos. The move came after a crown court judge last month threatened North Wales Police with legal action over its streamlined Arrive Alive anti-speeding campaign prosecution system. The system saw police officers' signatures scanned on to statements, which they were supposed to have read and signed personally. The automated system was scrapped in the light of Judge Derek Halbert's attack and dozens of speeding prosecutions delayed while fresh statements were prepared. The letters were sent to drivers across Britain summonsed to a North Wales court since June 6 last year on speeding charges, failing to furnish information, or associated offences. It affects those caught by mobile speed cameras who either pleaded not guilty and were found guilty, or who were convicted in their absence. They were approved by North Wales' top cop Richard Brunstrom, whose tough anti-speeding policies have sparked much controversy. In Police magazine, the official publication of the Police Federation in England and Wales, the chief con-stable was dubbed "the godfather of the speed camera". Last night a North Wales Police spokeswoman said the force could not predict the cost of potential re-trials. Last month Judge Halbert, in a case he branded unusual and disturbing, attacked the use of sworn statements prepared under the new automated procedure. |
