Two teenagers jailed for the brutal murder of Seacliff pensioner Anne Redman have launched appeals against their sentences.
The teenagers, now aged 18 and 19, pleaded guilty to murdering the 87-year-old in the backyard of her home on Australia Day in 2011 when she disturbed them during a break-in.
In November last year, both received mandatory life sentences with non-parole periods of 20 years after the sentencing judge described the murder as a senseless and horrific crime.
The pair cannot be publicly identified because they were juveniles at the time of the murder.
Both were given permission to argue that their sentences were excessive.
Their lawyers compared their case to that of the 14-year-old boy who was sentenced to at least 15 years in prison for bludgeoning a woman to death at Callington, saying that his was a case of premeditated murder and theirs was not.
The Court will also consider whether one of the teenagers should have been given a sentence discount for pleading guilty earlier and offering to give evidence against his co-accused.
