PROSECUTORS want to appeal against the two-year jail sentence for Oxford Eastern Bypass driver Angela Dublin, because they think it is too lenient.

The Crown Prosecution Service has asked the Attorney General to go to the Court of Appeal to ask for the term to be increased.

Dublin was jailed earlier this month for killing four people in last May's crash.

This week Dwain Haynes and Sam Hastings, parents of victims Marshall and Liam, welcomed the move. Mr Haynes called the initial two-year sentence an insult to the families.

Dublin, 45, of London Road, Headington, was sentenced to two years in jail after admitting causing the deaths of Marshall Haynes, Liam Hastings and Josh Bartlett, all 13, and Howard Hillsdon, 21, by dangerous driving.

Mr Haynes, of Greater Leys, said: "Once the case was sent to Crown Court I felt justice would be done.

"But now my question is why did a High Court judge issue a sentence which could have been dealt with the likes of speeding fines in a magistrates' court.

"The sentence is an insult to all the families who lost their loved ones and the boys' memories themselves.

"And what signal does the sentence send out to the rest of our society?"

At Oxford Crown Court this month, Mr Justice Crane said Dublin showed genuine remorse and anguish and a lengthy prison spell would impact on her physical and mental state.

Mr Haynes said: "I feel it is time to speak up and ask the question of our judicial system.

"Is my boy's life and that of three other innocent victims only worth a sentence more fitting of a shoplifter?

"For all the people who feel Mrs Dublin has suffered enough I ask them this; when they kiss their children goodnight ask themselves the question again, would she have suffered enough if it were their child that was thrown 100 feet from the boot of a car, yes, the boot, not a seat."

Mrs Hastings, of Rivermead, Rose Hill, said she was pleased there was a chance the sentence could be extended.

"What she got is nowhere near long enough," she said.

"She is going to miss one of her son's Christmases. We are going to miss at least 50 of Liam's.

"I know that even if the judge gives her 25 years it is not going to bring Liam back. But she has killed four people and I think she should get at least double figures," she said.

A spokesman for the Crown Prosecution Service said: "Papers have been passed to the Attorney General for him to consider whether it should be referred to the Court of Appeal as a potential unduly lenient sentence."

Attorney General Lord Goldsmith has until May 8 to decide whether to seek an appeal.

Usually it is defence solicitors who appeal against jail terms, but if the CPS takes the view a sentence passed in court is too lenient, lawyers can request a new hearing.

The case is first sent to the Treasury Counsel for advice and then passed to the CPS Casework Directorate lawyer to decide whether or not to alert the Attorney General.

Lord Goldsmith has the power under the Criminal Justice Act 1988 to refer a sentence which he believes is 'unduly lenient' to the Court of Appeal within 28 days of the original sentencing.

At a second sentence hearing, the Court of Appeal can decide whether to agree with the decision, impose a longer sentence, or disagree with the decision but leave the jail term as it is.

Victims, their families and members of the public can also appeal directly to the CPS to send a case to the Attorney General.

The maximum sentence for one conviction of causing death by dangerous driving is 14 years in custody.
