George, 42, was present in the dock as the Lord Chief Justice, Lord Woolf, sitting with Mr Justice Curtis and Mr Justice Henriques, said: “We will get our judgment out as soon as we can.”
George was found guilty in July last year of the April 1999 shooting of the 37-year-old BBC Crimewatch presenter on the steps of her home in Gowan Avenue, Fulham, south west London.
A jury at the Old Bailey convicted George by a majority of 10 to one after deliberating for more than 30 hours.
The appeal judges were told yesterday that the jury at George’s trial was “perfectly entitled to reach the safe conclusion” that he and no other murdered Jill Dando.
George’s sister Michelle Diskin, from Ballincollig, Co Cork, was present as Orlando Pownall QC, for the Crown, said that criticisms made of the handling of the case by trial judge Mr Justice Gage were “without foundation”.
“At every stage of the trial, he sought and, as we will endeavour to demonstrate, achieved fairness,” he said.
Mr Pownall rebutted claims by Michael Mansfield QC, for George, that the conviction was unsafe because identification evidence used at the trial was inadmissible and should have led to the proceedings being halted.
“The judge’s rulings in law in respect of the applications made to stay the proceedings for abuse of process, the admissibility of the evidence, and a submission of no case to answer, cannot be faulted,” said Mr Pownall.
“This is not a lurking doubt case.
“Based upon a careful consideration of all the evidence, the jury were perfectly entitled to reach the safe conclusion that this appellant and no other murdered Jill Dando.”
Mr Pownall said the Crown disagreed with the suggestion that the identification evidence in the case was “tenuous”.
He added: “The identification evidence in this case was the foundation stone upon which the Crown constructed the arguments it advanced to the jury.”
If the jury was sure that the identification of George by two witnesses and the partial qualified identifications of the other witnesses were accurate, they were entitled to ask themselves by reference to the other significant strands of evidence whether there could sensibly be any other contender.
If, on the other hand, they could not be sure, then they were bound to acquit.
Against the evidence of identification the jury “were entitled to look at the circumstantial evidence and it was there, we submit, in abundance”.
There was no evidence that someone had carried out a contract killing, said Mr Pownall.
The suggestion that there was a Serb or some other professional assassin nearby was “totally absurd”.
The jury was also entitled to take account of George’s fascination, “if not obsession”, with celebrities and his fascination with firearms and matters military.
Mr Mansfield had said the Crown had not been able to put a single document before the court which indicated that prior to her shooting Barry George had an obsessive interest in Jill Dando.
