A link between the men and Ms Manning, said to be proved by particles from a lighter, was questioned at the Court of Appeal.
Both men - whose cases have featured on the BBC's Rough Justice programme - have said they are victims of a miscarriage of justice and their convictions should be overturned as "unsafe".
Flint particles from a lighter were matched to Ms Manning's skirt after her disfigured body was dumped at Woburn Golf Club in Buckinghamshire, in 2000.
Mr White, now 29, was alleged to have strangled 18-year-old shop assistant Rachel and dumped her body in undergrowth near the 10th hole at Woburn Golf and Country Club, Bucks.
'Confused, imprecise, unreliable'
Mr White insisted that he had left Ms Manning in Milton Keynes after a night out.
However, both men - whose cases have featured on the BBC's Rough Justice programme - have said they are victims of a miscarriage of justice and their convictions should be overturned as "unsafe".
John Coffey QC said forensic evidence had now been "heavily undermined" by fresh scientific experiments.
Central to the prosecution case was the evidence of geologist, Professor Kenneth Pye, who pointed to an unusual "assemblage" of seven particles found both on Ms Manning's skirt and the passenger seat of Mr Hyatt's van, which was said to have been used to transport her body.
Two of the particles were flint debris from a disposable lighter which Professor Pye said provided "strong support" for a link between Ms Manning's skirt and Mr Hyatt's van.
Co-defendant Keith Hyatt, of Bedford, also won his appeal
Mr Hyatt was found guilty of perverting the course of justice.
However, Mr Coffey argued that further scientific tests since the trial, carried out by three experts, cast serious doubt on the reliability of Professor Pye's testimony.
Arguing that the evidence relating to the particles was "confused, imprecise, unreliable and open to many interpretations", the barrister said a central plank of the prosecution case had been "heavily undermined, if not completely swept away".
Professor Pye's interpretation of the particles was quite simply "incorrect", he told Lord Justice Keene, Mr Justice Jack and Mr Justice Irwin.
It was the prosecution case at trial that Mr White strangled Ms Manning after an argument in Milton Keynes, then called Mr Hyatt to help dispose of her body.
Mr White insisted that he had left Ms Manning in Milton Keynes after the night out.
