The Irish Independent reports that Boy B, who is appealing his conviction of the murder of Kildare school girl, Ana Kriegel, has hired Michael J Staines and Company, one of the country's leading criminal defence firms.
His decision to change legal teams meant his appeal, which had been due to get under way on April 24, had to be postponed to a later date.
The Irish Independent reports that Michael J Staines and Company "" has been involved in several high-profile cases in recent years," including the trial of former Anglo Irish Bank chair, Sean FitzPatrick, on charges of hiding loans from auditors.
He was given a 15-year sentence, to be reviewed after eight years.
While he did not assault Ana, he led her to the derelict farmhouse in Lucan, Co Dublin, where she was sexually assaulted and murdered by another teen, known as Boy A.
Both boys were 13 at the time.
Boy A was sentenced to a life term for murder and will serve an initial 12 years, followed by a review.
While Boy A denied murder and sexual assault at his trial, a court heard how subsequent to being convicted he accepted he caused Ana's death.
However, Boy B has maintained his innocence and court heard that he did not accept the verdict of the jury.
Boy B is seeking to appeal against his conviction only, meaning no appeal is being sought against the severity of his sentence.
The Irish Independent reports that his grounds of appeal have yet to be revealed.
