The 16-year-old hanged himself in Stoke Heath Young Offender Institution in March 2002. His mother Yvonne has been leading a campaign for a public inquiry into his death, with the backing of justice organisation Inquest.
In January this year the High Court ruled against a public inquiry.
The family is appealing against this at a two-day hearing starting on Monday (17 July). At a briefing last week campaigners vowed to continue to fight for an inquiry until they are successful.
Last week, Barnardo's chief executive Martin Narey told Young People Now he backs the campaign. He denied newspaper reports that he had opposed a public inquiry when he was director general of the Prison Service. He said he was a civil servant at the time and did not feel it was right for him to comment on the matter.
