One of the teenage boys found guilty of murdering schoolgirl Ana Kriegel will seek to have his conviction overturned on April 24.
The 15-year-old, referred to as Boy B, was unanimously found guilty of murdering the "lonely and vulnerable" schoolgirl last June and was sentenced to 15 years' detention, to be reviewed after eight years.
Boy A and Boy B, whose identities cannot be published as they are children, were just 13 when they murdered 14-year-old Ana in May 2018.
Boy B lured Ana from her home, knowing his friend was waiting to attack her in a derelict house in St Catherine's Park, Lucan.
He gave several different versions of events to gardai but eventually admitted seeing Boy A attacking Ana.
Now aged 15, they were unanimously found guilty of murder by a Central Criminal Court jury last June.
Boy A was also convicted of Ana's aggravated sexual assault in a manner that involved serious violence.
Boy A was sentenced to life imprisonment with a review after 12 years, and eight years' imprisonment for aggravated sexual assault. No appeal has been lodged on his behalf.
Boy B is seeking to appeal against his conviction only, meaning no appeal is being sought against the severity of his sentence.
During case management procedures in the Court of Appeal yesterday, April 24 was fixed as an early hearing date for Boy B's conviction appeal.
President of the Court of Appeal Mr Justice George Birmingham said arrangements would be put in place for the hearing that both sides consider appropriate.
As both boys were children, the Central Criminal Court adopted procedures from the Children's Court, which saw lawyers and judges wearing suits and ties rather than gowns.
Counsel for Boy B, Damien Colgan SC, said he expected the appeal hearing to take a day.
