The man who killed beloved outback nurse Gayle Woodford is to argue for a reduction in his 32-year minimum jail sentence.
Dudley Davey, 35, is listed to come before the Court of Criminal Appeal in Adelaide on Thursday after being granted leave to challenge the length of his non-parole period.
Defence counsel Nick Vadasz will argue that it's questionable whether or not the sentencing judge gave Davey enough discount for his guilty plea.
Mr Vadasz said the discount applied was about 10 per cent, much less than the maximum 30 per cent allowed under sentencing legislation.
The Crown is expected to argue that a bigger discount would have "shocked the public conscience" given the seriousness of Davey's offending and his appalling record.
The 35-year-old pleaded guilty to both the rape and murder of 56-year-old Ms Woodford, who was found buried in a crude grave three days after she went missing from her home in Fregon, in the state's north, in March last year.
