An appeal by the man convicted of raping and murdering Blessie Gotingco has been dismissed.
Tony Robertson had presented a cavalcade of complaints to the Court of Appeal, complaining his conviction for the deadly attack was unsound and the minimum 24-year sentence was unfair.
Among Robertson's complaints were claims had complained the prosecution misled the jury judge's summing up was biased, that the media was against him, that lawyers representing his interests made mistakes and that he wasn't given enough of a chance to prepare his defence.
In August the 28-year-old was sentenced to life imprisonment with a minimum-non-parole period of 24 years for murdering Mrs Gotingco and preventive detention for raping the mother and grandmother.
His the crimes against the 56-year-old came only months after Robertson was released from prison for similarly depraved offending.
