Richard Keedwell, 71, said a “seriously flawed” legal system meant fighting the fine had taken nearly three years and spent £30,000 of his life savings and sons’ inheritance on a failed legal battle over a £100 speeding fine.
He claims he was wrongly clocked doing 35mph in a 30mph zone on a day trip to Worcester in 2016.
The Crown Prosecution Service (CPS) said the case involved a “multiplicity of issues” which added to its length.
Retired engineer Mr Keedwell, of Yate near Bristol, claimed he “was certainly not doing more than 30mph” in New Road in November 2016.
He said: “I really could not believe that I had been speeding. It made a simple day out turn very sour actually.”
Mr Keedwell claimed he had “no case to answer” and recruited the help of a video and electronics expert who told the court the speed camera may have been triggered by a car in an adjacent lane or have been faulty.
However, he said it took four trips to Worcester Magistrates’ Court before his appeal was heard. After losing the case, he lost a further crown court appeal in August.
Mr Keedwell said he expected the case would be “fairly quick” but had spent “the best part of £30,000”, including about £21,000 in barristers’ fees and £7,000 in court costs, as well as travel expenses.
Mr Keedwell said he felt guilty his family would miss out and said the case had proved “very stressful. I regret the amount of money. I very simply wanted justice.”
