A date has been set for a hearing which will decide whether the sentence given to the killer of schoolboy Joe Geeling was too lenient.
Hamer's minimum term was set at 12 years
Michael Hamer repeatedly stabbed 11-year-old Joe and then dumped his body in a park in Bury, Greater Manchester, in March last year.
The 15-year-old was jailed for life for murder with a minimum term of 12 years.
The hearing, set for 17 January, follows a request to the Attorney General by prosecutors.
Tom and Gwen Geeling, Joe's parents, said Hamer's sentence was too short.
Joe was lured back to Hamer's home and repeatedly stabbed
On 1 March 2006 a massive search was launched for Joe, a cystic fibrosis sufferer, after he failed to return home from St Gabriel's High School in Bury.
His body was found hidden under debris in a gulley in Whitehead Park the next day.
Manchester Crown Court heard that Hamer had lured Joe back to his house, where he beat him with a frying pan and stabbed him 16 times.
After the attack, Hamer dragged Joe's body downstairs, put it in a wheelie bin and took the bin to Whitehead Park, where he hid it.
The court heard that the killing was probably triggered by Joe's rejection of a sexual advance by Hamer.
An iron artwork of a boy riding a bicycle has been erected in the grounds of Joe's former school as a permanent memorial.
